Roots vacuum pump (abbreviated as Roots pump) is a rotary variable capacity vacuum pump without internal compression. It utilizes 2 8-shaped rotors to rotate in the pump casing to generate suction and exhaust effects. Its principle is similar to that of a Roots blower. Due to its operation in a low pressure range, the gas molecules have a large free range, and the resistance of gas leakage through small slits is high, so it can achieve a high compression ratio and can be used as a booster vacuum pump; But it cannot directly discharge the gas into the atmosphere alone, and needs to be used in series with the front stage vacuum pump. The extracted gas is carried into the atmosphere through the front stage vacuum pump.
Roots pumps are widely used in vacuum degassing, vacuum melting, vacuum treatment of molten steel in the vacuum metallurgy industry, as well as in devices such as space simulation and low-density wind tunnels to extract corrosive gases. It can also be used in production processes such as distillation, evaporation, and drying in industries such as chemical, food, pharmaceutical, and motor manufacturing.
The ZJ series Roots vacuum pump is a rotary variable capacity vacuum pump that requires a front stage pump to be used. It has a large pumping speed in a wide pressure range in China and is not sensitive to dust and water vapor in the extracted gas. It is widely used in industries such as metallurgy, chemical industry, food, and electronic coating.

What Is a Roots Vacuum Pump, and How Does It Work?
A Roots vacuum pump, also known as a Roots blower or a rotary lobe pump, is a type of positive displacement vacuum pump that is widely used for various industrial applications. Here’s a detailed explanation of what a Roots vacuum pump is and how it works:
A Roots vacuum pump consists of two synchronized rotors, known as lobes or impellers, that rotate in opposite directions within a housing. The lobes have a unique helical shape with multiple lobes, which allows them to trap and move gas efficiently. The rotors are synchronized with the help of timing gears to maintain precise clearances between the lobes and the housing.
The operation of a Roots vacuum pump can be described in the following steps:
1. Inlet Stage: The process begins with the lobes rotating in opposite directions. As the lobes rotate, the volume between them and the housing gradually increases, creating a larger space at the inlet side of the pump. This expansion of the volume causes the gas to enter the pump through the inlet port. The gas is drawn in due to the pressure difference between the inlet and the pump’s internal chamber.
2. Compression Stage: As the gas enters the pump, it gets trapped in the spaces between the lobes and the housing. As the lobes continue to rotate, the trapped gas gets carried along the rotating lobes. The gas is essentially trapped in the pockets formed by the lobes and the housing. The rotating lobes then compress the gas as they move towards the outlet side of the pump.
3. Outlet Stage: As the lobes approach the outlet side of the pump, the volume between them and the housing decreases, resulting in the compression of the trapped gas. This compression raises the pressure of the gas, causing it to be expelled through the outlet port of the pump. The expelled gas is then discharged into the atmosphere or directed to a downstream process or another vacuum pump, depending on the application.
It’s important to note that a Roots vacuum pump operates as a non-contacting pump, meaning that there is no physical contact between the lobes or between the lobes and the housing. This characteristic eliminates the need for lubrication within the pump and reduces the risk of contamination or oil vapor backstreaming into the vacuum system.
Roots vacuum pumps are known for their high pumping speed and ability to handle large volumes of gas. However, they are not capable of achieving high vacuum levels on their own. To achieve higher vacuum levels, a Roots pump is often used in conjunction with other vacuum pumps, such as rotary vane pumps or diffusion pumps, in a hybrid or combination pumping system.
In summary, a Roots vacuum pump operates based on the principle of positive displacement. It utilizes synchronized rotating lobes to trap and compress gas, allowing it to be discharged at a higher pressure. The non-contacting design of the pump eliminates the need for lubrication and reduces the risk of contamination. Roots vacuum pumps are commonly employed in various industrial applications, especially when high pumping speed and large gas handling capacity are required.

By creating a vacuum in the intake manifold or other engine components, these pumps enable the detection of leaks and ensure the integrity of the engine’s air delivery system.
– Air Flow Calibration: During engine testing and calibration, Roots vacuum pumps are used to simulate various operating conditions by controlling the intake air flow. This allows engineers to fine-tune the engine’s performance, optimize fuel-air mixture ratios, and assess the engine’s efficiency and emissions characteristics.
4. HVAC Systems:
– Climate Control: Roots vacuum pumps are employed in automotive HVAC (Heating, Ventilation, and Air Conditioning) systems to facilitate the flow and distribution of air. These pumps help regulate the operation of HVAC components, such as air blend doors and vacuum actuators, ensuring proper air temperature and direction control inside the vehicle cabin.
5. Fuel System and Turbocharging:

These devices compress and force air into the engine’s intake manifold, resulting in increased engine power and performance.
In summary, Roots vacuum pumps find extensive utilization in the automotive industry. They play a crucial role in brake systems, emissions control, engine testing and development, HVAC systems, fuel systems, turbocharging, electric vehicle battery systems, and engine air induction. By contributing to braking performance, emissions reduction, engine calibration, HVAC functionality, fuel system efficiency, turbocharger control, battery system safety, and engine power enhancement, Roots vacuum pumps contribute significantly to the overall operation and performance of automotive systems and components.
What Is a Roots Vacuum Pump, and How Does It Work?
A Roots vacuum pump, also known as a Roots blower or a rotary lobe pump, is a type of positive displacement vacuum pump that is widely used for various industrial applications. Here’s a detailed explanation of what a Roots vacuum pump is and how it works:
A Roots vacuum pump consists of two synchronized rotors, known as lobes or impellers, that rotate in opposite directions within a housing. The lobes have a unique helical shape with multiple lobes, which allows them to trap and move gas efficiently. The rotors are synchronized with the help of timing gears to maintain precise clearances between the lobes and the housing.
The operation of a Roots vacuum pump can be described in the following steps:
1. Inlet Stage: The process begins with the lobes rotating in opposite directions. As the lobes rotate, the volume between them and the housing gradually increases, creating a larger space at the inlet side of the pump. This expansion of the volume causes the gas to enter the pump through the inlet port. The gas is drawn in due to the pressure difference between the inlet and the pump’s internal chamber.
2. Compression Stage: As the gas enters the pump, it gets trapped in the spaces between the lobes and the housing. As the lobes continue to rotate, the trapped gas gets carried along the rotating lobes. The gas is essentially trapped in the pockets formed by the lobes and the housing. The rotating lobes then compress the gas as they move towards the outlet side of the pump.
3. Outlet Stage: As the lobes approach the outlet side of the pump, the volume between them and the housing decreases, resulting in the compression of the trapped gas. This compression raises the pressure of the gas, causing it to be expelled through the outlet port of the pump. The expelled gas is then discharged into the atmosphere or directed to a downstream process or another vacuum pump, depending on the application.
It’s important to note that a Roots vacuum pump operates as a non-contacting pump, meaning that there is no physical contact between the lobes or between the lobes and the housing. This characteristic eliminates the need for lubrication within the pump and reduces the risk of contamination or oil vapor backstreaming into the vacuum system.
Roots vacuum pumps are known for their high pumping speed and ability to handle large volumes of gas. However, they are not capable of achieving high vacuum levels on their own. To achieve higher vacuum levels, a Roots pump is often used in conjunction with other vacuum pumps, such as rotary vane pumps or diffusion pumps, in a hybrid or combination pumping system.
In summary, a Roots vacuum pump operates based on the principle of positive displacement. It utilizes synchronized rotating lobes to trap and compress gas, allowing it to be discharged at a higher pressure. The non-contacting design of the pump eliminates the need for lubrication and reduces the risk of contamination. Roots vacuum pumps are commonly employed in various industrial applications, especially when high pumping speed and large gas handling capacity are required.

ZJ Series Roots vacuum pump
1. Construction features and working principle of the pump:
Model ZJ Mechanical Booster Pump, also known as a Roots pump, is a volumetric pump.
It employs a pair of rotors, identical and in 8-figure with certain clearance between them
in the pump housing, rotating at the same speed in opposite directions to perform
function of suction and discharge of gas. The 2 rotors are supported by rolling bearings
in the end covers of the pump, rotating at high speed and are kept at a
fixed relative position by a pair of timing gears. The end clearance between rotors and
end covers are fixed by adjustable metal shims between the bearing housings and the
end cover at the fixed end, which ensures one-direction expansion of the rotor when
temperature rises during its operation.
Four sets of inner seals (also known as piston ring) in the 2 end covers prevent lube oil
entering into the pump housing. The shaft seal at the front-end cover, also called as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In order to reduce temperature of the pump, all models of pumps (expect the two
smallest models) are equipped with a gearbox cooler and front-end cover cooler.
Power is transmitted through a coupling or V-belt from the motor to the driving shaft of
the pump and then through synchronizing gears to the driven shaft

Can Roots Vacuum Pumps Be Used for Vacuum Distillation?
Yes, Roots vacuum pumps can be used for vacuum distillation in certain applications. Here’s a detailed explanation:
Vacuum distillation is a process used to separate and purify components of a liquid mixture by exploiting the difference in boiling points under reduced pressure. By operating at lower pressures, the boiling points of the components are decreased, allowing for more selective evaporation and separation. Vacuum distillation is commonly employed in industries such as petrochemical, pharmaceutical, and chemical manufacturing.
Roots vacuum pumps can play a role in vacuum distillation processes by assisting in the creation and maintenance of the required vacuum conditions. Although Roots vacuum pumps alone may not achieve the high vacuum levels necessary for certain applications, they are often used in combination with other vacuum pumps, such as rotary vane pumps or oil-sealed pumps, to create a hybrid pumping system.
In a typical setup, Roots vacuum pumps are utilized as the primary roughing pump in the distillation system. Their high pumping speed allows for efficient removal of large volumes of gas, reducing the pressure in the system and enabling the effective operation of subsequent stages. The Roots pump works by trapping and compressing the gas, creating a pressure differential that facilitates the evacuation of the system.
While Roots vacuum pumps are effective in generating rough vacuum levels, they may not be capable of achieving the very high vacuum levels often required for precise separation in vacuum distillation. Therefore, they are commonly used in conjunction with other vacuum pumps, such as oil-sealed pumps or molecular pumps, that are better suited for achieving and maintaining high vacuum levels.
It’s important to note that the selection and configuration of the vacuum pumps for vacuum distillation depend on various factors, including the desired vacuum level, the characteristics of the liquid mixture being distilled, and the specific requirements of the distillation process. The vacuum system needs to be carefully designed to ensure optimal performance and efficient separation.
In summary, while Roots vacuum pumps alone may not be sufficient for achieving the high vacuum levels required for vacuum distillation, they are commonly employed as part of a hybrid pumping system in conjunction with other vacuum pumps. Their high pumping speed and capability to handle large gas volumes make them valuable for creating the initial vacuum conditions in the distillation process.

What Is the Impact of Altitude on Vacuum Pump Performance?
The performance of vacuum pumps can be influenced by the altitude at which they are operated. Here’s a detailed explanation:
Altitude refers to the elevation or height above sea level. As the altitude increases, the atmospheric pressure decreases. This decrease in atmospheric pressure can have several effects on the performance of vacuum pumps:
1. Reduced Suction Capacity: Vacuum pumps rely on the pressure differential between the suction side and the discharge side to create a vacuum. At higher altitudes, where the atmospheric pressure is lower, the pressure differential available for the pump to work against is reduced. This can result in a decrease in the suction capacity of the vacuum pump, meaning it may not be able to achieve the same level of vacuum as it would at lower altitudes.
2. Lower Ultimate Vacuum Level: The ultimate vacuum level, which represents the lowest pressure that a vacuum pump can achieve, is also affected by altitude. As the atmospheric pressure decreases with increasing altitude, the ultimate vacuum level that can be attained by a vacuum pump is limited. The pump may struggle to reach the same level of vacuum as it would at sea level or lower altitudes.
3. Pumping Speed: Pumping speed is a measure of how quickly a vacuum pump can remove gases from a system. At higher altitudes, the reduced atmospheric pressure can lead to a decrease in pumping speed. This means that the vacuum pump may take longer to evacuate a chamber or system to the desired vacuum level.
4. Increased Power Consumption: To compensate for the decreased pressure differential and achieve the desired vacuum level, a vacuum pump operating at higher altitudes may require higher power consumption. The pump needs to work harder to overcome the lower atmospheric pressure and maintain the necessary suction capacity. This increased power consumption can impact energy efficiency and operating costs.
5. Efficiency and Performance Variations: Different types of vacuum pumps may exhibit varying degrees of sensitivity to altitude. Oil-sealed rotary vane pumps, for example, may experience more significant performance variations compared to dry pumps or other pump technologies. The design and operating principles of the vacuum pump can influence its ability to maintain performance at higher altitudes.
It’s important to note that vacuum pump manufacturers typically provide specifications and performance curves for their pumps based on standardized conditions, often at or near sea level. When operating a vacuum pump at higher altitudes, it is advisable to consult the manufacturer’s guidelines and consider any altitude-related limitations or adjustments that may be necessary.
In summary, the altitude at which a vacuum pump operates can have an impact on its performance. The reduced atmospheric pressure at higher altitudes can result in decreased suction capacity, lower ultimate vacuum levels, reduced pumping speed, and potentially increased power consumption. Understanding these effects is crucial for selecting and operating vacuum pumps effectively in different altitude environments.
Can Vacuum Pumps Be Used for Soil and Groundwater Remediation?
Vacuum pumps are indeed widely used for soil and groundwater remediation. Here’s a detailed explanation:
Soil and groundwater remediation refers to the process of removing contaminants from the soil and groundwater to restore environmental quality and protect human health. Vacuum pumps play a crucial role in various remediation techniques by facilitating the extraction and treatment of contaminated media. Some of the common applications of vacuum pumps in soil and groundwater remediation include:
1. Soil Vapor Extraction (SVE): Soil vapor extraction is a widely used remediation technique for volatile contaminants present in the subsurface. It involves the extraction of vapors from the soil by applying a vacuum to the subsurface through wells or trenches. Vacuum pumps create a pressure gradient that induces the movement of vapors towards the extraction points. The extracted vapors are then treated to remove or destroy the contaminants. Vacuum pumps play a vital role in SVE by maintaining the necessary negative pressure to enhance the volatilization and extraction of contaminants from the soil.
2. Dual-Phase Extraction (DPE): Dual-phase extraction is a remediation method used for the simultaneous extraction of both liquids (such as groundwater) and vapors (such as volatile organic compounds) from the subsurface. Vacuum pumps are utilized to create a vacuum in extraction wells or points, drawing out both the liquid and vapor phases. The extracted groundwater and vapors are then separated and treated accordingly. Vacuum pumps are essential in DPE systems for efficient and controlled extraction of both liquid and vapor-phase contaminants.
3. Groundwater Pumping and Treatment: Vacuum pumps are also employed in groundwater remediation through the process of pumping and treatment. They are used to extract contaminated groundwater from wells or recovery trenches. By creating a vacuum or negative pressure, vacuum pumps facilitate the flow of groundwater towards the extraction points. The extracted groundwater is then treated to remove or neutralize the contaminants before being discharged or re-injected into the ground. Vacuum pumps play a critical role in maintaining the required flow rates and hydraulic gradients for effective groundwater extraction and treatment.
4. Air Sparging: Air sparging is a remediation technique used to treat groundwater and soil contaminated with volatile organic compounds (VOCs). It involves the injection of air or oxygen into the subsurface to enhance the volatilization of contaminants. Vacuum pumps are utilized in air sparging systems to create a vacuum or negative pressure zone in wells or points surrounding the contaminated area. This induces the movement of air and oxygen through the soil, facilitating the release and volatilization of VOCs. Vacuum pumps are essential in air sparging by maintaining the necessary negative pressure gradient for effective contaminant removal.
5. Vacuum-Enhanced Recovery: Vacuum-enhanced recovery, also known as vacuum-enhanced extraction, is a remediation technique used to recover non-aqueous phase liquids (NAPLs) or dense non-aqueous phase liquids (DNAPLs) from the subsurface. Vacuum pumps are employed to create a vacuum or negative pressure gradient in recovery wells or trenches. This encourages the movement and extraction of NAPLs or DNAPLs towards the recovery points. Vacuum pumps facilitate the efficient recovery of these dense contaminants, which may not be easily recoverable using traditional pumping methods.
It’s important to note that different types of vacuum pumps, such as rotary vane pumps, liquid ring pumps, or air-cooled pumps, may be used in soil and groundwater remediation depending on the specific requirements of the remediation technique and the nature of the contaminants.
In summary, vacuum pumps play a vital role in various soil and groundwater remediation techniques, including soil vapor extraction, dual-phase extraction, groundwater pumping and treatment, air sparging, and vacuum-enhanced recovery. By creating and maintaining the necessary pressure differentials, vacuum pumps enable the efficient extraction, treatment, and removal of contaminants, contributing to the restoration of soil and groundwater quality.

Types of vacuum pumps
A vacuum pump is a device that draws gas molecules from a sealed volume and leaves a partial vacuum in its wake. Its job is to create a relative vacuum within a specific volume or volume. There are many types of vacuum pumps, including centrifugal, screw and diaphragm.
Forward centrifugal pump
Positive displacement centrifugal vacuum pumps are one of the most commonly used pump types in the oil and gas industry. Their efficiency is limited to a range of materials and can handle relatively high solids concentrations. However, using these pumps has some advantages over other types of pumps.
Positive displacement pumps have an enlarged cavity on the suction side and a reduced cavity on the discharge side. This makes them ideal for applications involving high viscosity fluids and high pressures. Their design makes it possible to precisely measure and control the amount of liquid pumped. Positive displacement pumps are also ideal for applications requiring precise metering.
Positive displacement pumps are superior to centrifugal pumps in several ways. They can handle higher viscosity materials than centrifuges. These pumps also operate at lower speeds than centrifugal pumps, which makes them more suitable for certain applications. Positive displacement pumps are also less prone to wear.
Positive displacement vacuum pumps operate by drawing fluid into a chamber and expanding it to a larger volume, then venting it to the atmosphere. This process happens several times per second. When maximum expansion is reached, the intake valve closes, the exhaust valve opens, and fluid is ejected. Positive displacement vacuum pumps are highly efficient and commonly used in many industries.
Self-priming centrifugal pump
Self-priming centrifugal pumps are designed with a water reservoir to help remove air from the pump. This water is then recirculated throughout the pump, allowing the pump to run without air. The water reservoir can be located above or in front of the impeller. The pump can then reserve water for the initial start.
The casing of the pump contains an increasingly larger channel forming a cavity retainer and semi-double volute. When water enters the pump through channel A, it flows back to the impeller through channels B-C. When the pump is started a second time, the water in the pump body will be recirculated back through the impeller. This recycling process happens automatically.
These pumps are available in a variety of models and materials. They feature special stainless steel castings that are corrosion and wear-resistant. They can be used in high-pressure applications and their design eliminates the need for inlet check valves and intermediate valves. They can also be equipped with long intake pipes, which do not require activation.
Self-priming centrifugal pumps are designed to run on their own, but there are some limitations. They cannot operate without a liquid source. A foot valve or external liquid source can help you start the self-priming pump.
Screw Pump
The mechanical and thermal characteristics of a screw vacuum pump are critical to its operation. They feature a small gap between the rotor and stator to minimize backflow and thermal growth. Temperature is a key factor in their performance, so they have an internal cooling system that uses water that circulates through the pump’s stator channels. The pump is equipped with a thermostatically controlled valve to regulate the water flow. Also includes a thermostatic switch for thermal control.
Screw vacuum pumps work by trapping gas in the space between the rotor and the housing. The gas is then moved to the exhaust port, where it is expelled at atmospheric pressure. The tapered discharge end of the screw further reduces the volume of gas trapped in the chamber. These two factors allow the pump to work efficiently and safely.
Screw vacuum pumps are designed for a variety of applications. In some applications, the pump needs to operate at very low pressures, such as when pumping large volumes of air. For this application, the SCREWLINE SP pump is ideal. Their low discharge temperature and direct pumping path ensure industrial process uptime. These pumps also feature non-contact shaft seals to reduce mechanical wear. Additionally, they feature a special cantilever bearing arrangement to eliminate potential sources of bearing failure and lubrication contamination.
Screw vacuum pumps use an air-cooled screw to generate a vacuum. They are compact, and clean, and have a remote monitoring system with built-in intelligence. By using the app, users can monitor pump performance remotely.
Diaphragm Pump
Diaphragm vacuum pumps are one of the most common types of vacuum pumps found in laboratories and manufacturing facilities. The diaphragm is an elastomeric membrane held in place around the outer diameter. While it is not possible to seal a diaphragm vacuum pump, there are ways to alleviate the problems associated with this design.
Diaphragm vacuum pumps are versatile and can be used in a variety of clean vacuum applications. These pumps are commercially available with a built-in valve system, but they can also be modified to include one. Because diaphragm pumps are so versatile, it’s important to choose the right type for the job. Understanding how pumps work will help you match the right pump to the right application.
Diaphragm vacuum pumps offer a wide range of advantages, including an extremely long service life. Most diaphragm pumps can last up to ten thousand hours. However, they may be inefficient for processes that require deep vacuum, in which case alternative technologies may be required. Additionally, due to the physics of diaphragm pumps, the size of these pumps may be limited. Also, they are not suitable for high-speed pumping.
Diaphragm vacuum pumps are a versatile subset of laboratory pumps. They are popular for their oil-free construction and low maintenance operation. They are available in a variety of styles and have many optional features. In addition to low maintenance operation, they are chemically resistant and can be used with a variety of sample types. However, diaphragm pumps tend to have lower displacements than other vacuum pumps.
Atmospheric pressure is a key factor in a vacuum pump system
Atmospheric pressure is the pressure created by the collision of air molecules. The more they collide, the greater the pressure. This applies to pure gases and mixtures. When you measure atmospheric pressure, the pressure gauge reads about 14.7 psia. The higher the pressure, the greater the force on the gas molecules.
The gas entering the vacuum pump system is below atmospheric pressure and may contain entrained liquids. The mechanism of this process can be explained by molecular kinetic energy theory. The theory assumes that gas molecules in the atmosphere have high velocities. The resulting gas molecules will then start moving in random directions, colliding with each other and creating pressure on the walls of the vacuum vessel.
Atmospheric pressure is a critical factor in a vacuum pump system. A vacuum pump system is useless without proper atmospheric pressure measurement. The pressure in the atmosphere is the total pressure of all gases, including nitrogen and oxygen. Using total pressure instead of partial pressure can cause problems. The thermal conductivity of various gases varies widely, so working at full pressure can be dangerous.
When choosing a vacuum pump, consider its operating range. Some pumps operate at low atmospheric pressure, while others are designed to operate at high or ultra-high pressure. Different types of pumps employ different technologies that enhance their unique advantages.
The screw pump is less efficient in pumping gases with smaller molecular weight
Vacuuming requires a high-quality pump. This type of pump must be able to pump gas of high purity and very low pressure. Screw pumps can be used in laboratory applications and are more efficient when pumping small molecular weight gases. Chemical resistance is critical to pump life. Chemical resistant materials are also available. Chemically resistant wetted materials minimize wear.
Gear pumps are more efficient than screw pumps, but are less efficient when pumping lower molecular weight gases. Gear pumps also require a larger motor to achieve the same pumping capacity. Compared to gear pumps, progressive cavity pumps also have lower noise levels and longer service life. In addition, gear pumps have a large footprint and are not suitable for tight spaces.
Progressive cavity pumps have two or three screws and a housing and side cover. They are also equipped with gears and bearings. Their mechanical design allows them to operate in high pressure environments with extremely low noise. The progressive cavity pump is a versatile pump that can be used in a variety of applications.
Dry screw compressors have different aspect ratios and can operate at high and low pressures. The maximum allowable differential pressure for screw compressors ranges from 0.4 MPa for 3/5 rotors to 1.5 MPa for 4/6 rotors. These numbers need to be determined on a case-by-case basis.
