Pv20 Pv22 Excavator CZPT Pump
CZPT Sauer PV pump
CZPT Sauer-Sundstrand axial piston pump PV20, PV21, PV22, PV23, PV24, PV25, PV26, PV27
| Description |
Closed circuit
Sequence twenty
Dimensions: 20, 21, 22, 23, 24, twenty five, 26, 27
Nominal force 210 bars, Greatest pressure 350 bars.
The Sauer PV axial piston variable displacement pumps, Sequence 20, are of swash plate building with variable stream capability ideal for hydrostatic transmissions with shut circuit. The flow fee is proportional to the pumps driven speed displacement, which, in turn, is identified by the swash plate angle. The latter is infinitely adjustable between zero and optimum displacement. Movement course is reserved by titling the swash plate to the opposite facet of the neutral or zero displacement place. These units and elements are in shape, sort and purpose replacements for Sauer-Sundstrand series 20 elements.
– Suited for a selection of apps
– Several displacements and choices offered
– 8 various frame dimensions
– Engineered to provide a lengthy service lifestyle and reliability
– Mounted displacement motor can be operated in both route of rotation
– Multiple travel shaft alternatives and control choices
– Hefty obligation bearings and shafts
– Easily serviceable
– Substitute components also obtainable
– Direct replacements for Sauer-Sundstrand
