Open Circuit Axial Piston Pump

Fixed displacement hydraulic pump for open loop operation

Get the high-efficiency, open-circuit piston pumps you need for powerful and reliable performance. The HF open circuit axial piston pump is designed based on our closed-circuit pump technology, using the same core components as our HPV series pumps of equivalent displacement. Currently available in 70 ml/r and 90 ml/r displacement options, we’re also ready to develop other displacements based on your needs. Whether for construction machinery, agricultural and forestry equipment, or industrial machines, the HF open circuit axial piston pump provides the hydraulic power to keep your equipment running efficiently.

Key Parameters

Displacement (ml/r): 70, 90
Rated pressure (Mpa): 25
Max. pressure (Mpa): 28

Typical Applications

Cranes

Forklifts

Wheel Loaders

Agricultural and Forestry Machinery
Other machinery designed with open-circuit systems

Features

Max Input Speed: Up to 3000 r/min for high-performance applications
Versatile Control Options: Choose from load-sensing control and pressure compensation control to match your specific needs
Through-Shaft Design: Allows for convenient series operation with other pumps
Robust Bearing Design: Tapered roller bearings enable the shaft to handle larger external loads
Basket-Type Swing Design: Built for durability, ease of maintenance, and a longer lifespan
Integrated, Gasket-Free Design: Reduces operating noise and minimizes leakage for a cleaner, quieter operation
Universal Mounting: Flange, shaft, and ports use an international standard design for easy interchangeability
