Product Description
PV20 hydraulic piston pump used for construction machinery
Sauer PV pump: Hydraulic Sauer-Sundstrand axial piston pump PV20, PV21, PV22, PV23, PV24, PV25, PV26, PV27Closed circuit
Specification Description1. Series 20
2. Size: 20, 21, 22, 23, 24, 25, 26, 27
3. Nominal pressure 210 bars, Maximum pressure 350 bars.
The Sauer PV axial piston variable displacement pumps, Series 20, are of swash plate construction with variable flow capability suitable for hydrostatic transmissions with closed circuit. The flow rate is proportional to the pumps driven speed displacement, which, in turn, is determined by the swash plate angle. The latter is infinitely adjustable between zero and maximum displacement. Flow direction is reserved by titling the swash plate to the opposite side of the neutral or zero displacement position. These units and parts are fit, form and function replacements for Sauer-Sundstrand series 20 components.
- Suitable for a variety of applications
- Multiple displacements and options available
- 8 different frame sizes
- Engineered to provide a long service life and reliability
- Fixed displacement motor can be operated in either direction of rotation
- Multiple drive shaft options and control options
- Heavy duty bearings and shafts
- Easily serviceable
- Replacement parts also available
- Direct replacements for Sauer-Sundstrand
