Specification: 45~135 cc/rev
Nominal pressure: 400~420 bar
Maximum pressure: 450 bar
Swash plate design axial piston variable displacement pump for closed-loop hydrostatic transmission.
As the swash plate passes through the center, the direction of hydraulic oil flow changes smoothly.
Two pressure relief valves are installed on the high pressure side to prevent overloading.
Built-in make-up pump acts as make-up pump and control pump.
The maximum make-up pressure is limited by the built-in low-pressure relief valve.
New slewing components and bearings for improved transmission efficiency and higher input speed.
Optimized shell design, shock absorption and noise reduction.
Electrical proportional displacement control to meet the requirements of multi-industry applications.
A variety of oil outlet connection methods to optimize the pipeline connection.
Optional flushometer for direct mounting on the pump body.
