H Series variable-displacement axial piston pumps PVH33, PVH53, PVH71, PVH90 and PVH112 are designed for closed-circuit hydraulic systems. They are used in hydrostatic transmissions for travel drives and working equipment of combine harvesters, road-building machinery and other mobile equipment.
Applications:
- combine harvesters;
- truck mixers;
- road rollers.
According to the applicable technical specifications (TU), Hydrosila products are intended for use in hydraulic systems of tractors, vehicles, agricultural machinery and road-building equipment.
According to the applicable technical specifications (TU), Hydrosila products are not classified as dual-use products.
PVH Series pumps are based on the Sauer Series 20 design concept and have been significantly upgraded using Hydrosila’s many years of engineering and manufacturing experience. These improvements have enhanced the technical and operating characteristics of the main components while retaining the proven reliability of the original design concept.
The pumps are designed for heavy-duty operating conditions and are intended for hydrostatic transmissions of construction, road-building, agricultural and other mobile machinery.
Features:
- axial piston swashplate design;
- variable displacement;
- high volumetric efficiency;
- integrated charge pump;
- smooth reversal of hydraulic fluid flow direction;
- high-pressure relief valve;
- high-wear-resistance bimetallic valve plate;
- lightweight pistons for reliable operation under high-load conditions;
- tapered roller bearings designed to withstand significant radial and axial loads;
- radial or face-type drive shaft seal for reliable external sealing;
- mounting flanges in accordance with SAE standards;
- SAE tandem mounting capability.
Hydraulic fluids: mineral and special oils with a kinematic viscosity of 30...70 mm²/s at +50 °C.
The fluids must comply with DIN 51524-2.
