APPLICATION
Piston pumps are widely used in high-pressure, high-flow, high-power systems and where the flow needs to be regulated, such as mobile and construction equipment, engineering vehicles, heavy-duty planers, metal forming and stamping, machine tools, hydraulic presses, oilfield equipment, mining and metallurgical machinery, marine and other hydraulic systems.
Features
Variable motor with axial tapered piston rotary group of bentaxis design, for hydrostatic drives in open and closed circuits
– For use in mobile and stationary applications
– The wide control range enables the variable motor to satisfy
the requirement for high speed and high torque.
– The displacement can be infinitely changed from
Vg max to Vg min = 0.
– The output speed is dependent on the flow of the pump and
the displacement of the motor.
– The output torque increases with the pressure differential
between the high-pressure and low-pressure side and with
increasing displacement.
– Wide control range with hydrostatic transmissions
– Wide selection of control devices
– Cost savings through elimination of gear shifts and possibility of using smaller pumps
– Compact, robust motor with long service life
– High power density
– Good starting characteristics
– Small swing torque
