PV20 sauer hydraulic pump used for excavator
Application Range:
Concrete mixers, mining machinery, vehicles, industrial, road rollers, pavers,
stabilized soil mixing machine, concrete pump, pharmaceutical machinery, etc.
Sauer Series 20 Axial Piston Variable Displacement Pump Features:
1. Series 20 Axial Piston Variable Displacement Pumps are well engineered and easy
to handle.
2. The full-length shaft with a highly efficient tapered roller bearing
arrangement offers a high loading capacity for external radical forces.
3. The pumps can be connected with other additional pumps.
4. The hydro-mechanical servo displacement control maintains the selected swash
plate position and hence pumps displacement.
5. Upon release of the control handle, the swash plate automatically returns to
zero position and the flow reduces to zero.
6. High case pressures can be achieved without leakage even at the lowest
temperatures by using suitable shaft seals.
7. The servo valve arrangement offers the facility to incorporate function
regulators and remote control systems.
8. Axial piston units are designed for easy servicing. Complete dismantling and
reassembly can be carried out with standard hand tools, and all components or sub
-assemblies are replaceable.
