Description  

Open up circuit
Nominal pressure 5100 psi (350 bars)
Greatest force 5800 psi (four hundred bars)
 
The A11VLO variable axial piston pump of swash plate design and style for hydrostatic drives in open up circuit hydraulic technique
– Developed mainly for use in mobile applications.
– The pump operates beneath self-priming situations, with tank pressurization, or with an optional constructed-in cost pump (impeller).
– A complete variety of handle options is available matching any software need.
– Power manage option is externally adjustable, even when the pump is working.
– The via generate is ideal for incorporating gear pumps and axial piston pumps up to the exact same measurement, i.e. a hundred% through generate.
– The output movement is proportional to the generate speed and infinitely variable among qV max and qV min = .
– Control products: LR, LR.C, LR3, LG1, LG2, DR, DRS, DRL, DH1, DH2, DH.D, DH.G, EP1, EP2, DE.D, EP.G, and many others.
