Variable displacement axial-piston pump for hydraulic systems with closed circuit. They are used in hydrostatic transmission of stroke drive or operating equipment of combines, road and construction mobile machines.
Application:
- Combines
- Concrete mixer trucks
- Road rollers
The pumps PVH series are a cost competitive solution for a variety of applications.The design is based on the Sauer 20 series. The large-scale modernization, carried out on the basis of long-term experience of the company, allowed to increase considerably technical and operational characteristics of units and kept the famous reliability and durability. These pumps meet the requirements of heavy-duty applications in construction, road and agricultural machinery.
Charcteristics:
- Swashplate design.
- High volumetric efficiency.
- Build-in charge pump.
- Smooth flow direction change.
- High pressure relief valve.
- Bimetal bearing plate has a high wear-resistance.
- Lightweight piston provides reliability in operation at high speeds.
- Tapered roller bearings allow the pump shaft to withstand high radial and axial loads.
- Shaft seals (face seal or lip seal) provide reliable external tightness.
- Mounting flanges according to SAE.
- Possibility of tandem according to SAE.
Control systems:
- hydromechanical
- hydraulic proportional
- electrical 3-positioned 12/24B
