The HA2F/1~5 Series Axial Piston Pump is a high-performance hydraulic pump designed exclusively for construction machinery applications. Featuring a swash plate axial piston design, it supports both open and closed circuit operation. With a maximum speed of 7500 rpm, nominal pressure of 315 bar, and peak pressure up to 350 bar, the HA2F/1~5 Series is engineered to deliver reliable, efficient, and long-lasting performance under demanding working conditions.
The HA2F/1~5 Series is purpose-built for construction equipment, including:
Excavators – ensuring smooth hydraulic power for boom and bucket operation
Bulldozers – supporting blade lifting and precise control
Wheel Loaders – providing consistent hydraulic energy for heavy-duty lifting
Concrete Pumps – delivering stable hydraulic flow for continuous pumping
Road Machinery – enabling efficient drive and steering functions
High Efficiency: Spherical oil distribution with automatic alignment reduces leakage and maximizes output.
Durability: Designed with heavy-duty materials to withstand harsh construction environments.
High Pressure Operation: Rated at 315 bar, maximum 350 bar, suitable for tough engineering tasks.
Compact & Versatile: Wide displacement range from 9.4 ml/r to 500 ml/r for different machine types.
Low Maintenance: Long service life reduces downtime and operating costs.
Strong Load Capacity: Drive shaft engineered to handle radial loads, ideal for heavy construction machinery.
