Applications:

  • Combine harvesters
  • Concrete mixer trucks
  • Road rollers

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.

PVS series pumps provide a cost-competitive solution for a wide range of operating conditions. Their time-proven design, based on the Sauer Series 20 platform, offers excellent reliability and durability in demanding field applications.

Features:

  • Swash plate design.
  • High volumetric efficiency.
  • Integrated charge pump.
  • Smooth change of flow direction.
  • The bimetallic valve plate provides high wear resistance.
  • The lightweight piston design ensures reliable operation under maximum load conditions.
  • Mounting flanges are manufactured in accordance with the international SAE standard.
  • Tapered roller bearings enable the pump to withstand high radial and axial loads.
  • Shaft face seal ensures reliable external sealing.

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.
