According to the technical specifications (TU), Hydrosila products are intended for operation in hydraulic systems of tractors, vehicles, agricultural machinery, and construction and road equipment. Hydrosila hydraulic components are not intended for use in aviation or military equipment, or in the chemical, medical, light, and food industries. They must not be used for pumping chemical liquids or in hydraulic systems operating with water-based fluids containing special glycols or water.
Not a dual-use product.
PVH series pumps are a cost-competitive solution for various operating conditions. The design is based on the Sauer Series 20 platform. A major modernization, carried out based on the company’s long-term experience, has significantly improved technical and operational characteristics while preserving the well-known reliability and durability. These pumps meet the requirements of heavy-duty operating conditions for use in construction, road, and agricultural machinery.
Features:
- Swash plate design.
- High volumetric efficiency.
- Integrated charge pump.
- Smooth change of flow direction.
- High-pressure relief valve.
- The bimetallic wear plate provides high wear resistance.
- The lightweight piston ensures reliable operation under maximum load conditions.
- Tapered roller bearings enable the pump to withstand high radial and axial loads.
- Radial or face shaft seals ensure reliable external sealing.
- Mounting flanges are manufactured in accordance with the international SAE standard.
- SAE-standard tandem mounting capability.
Hydraulic fluids: mineral and special oils with a kinematic viscosity of 30...70 mm²/s at a temperature of +50°C. Fluids must comply with DIN 51525.
