WA4VTG Series Variable Piston Pump-Closed Circuit Variable Pumps-Wenzhou Hysem Hydraulics Co.,Ltd

Features

-Variable axial piston pump of swashplate design for hydro-static drives in closed circuit

-The flow is proportional to the drive speed and displacement.

-The flow increases as the angle of the swashplate is adjusted from zero to its maximum value

-Flow direction changes smoothly when the swashplate is moved through the neutral position.

-Two pressure-relief valves are provided on the high pressure ports to protect the hydrostatic transmission (pump and motor) from overload.

- The high-pressure relief valves also function as boost valves

-The integrated boost pump acts as a feed pump and control pressure supply.

- The maximum boost pressure is limited by a built-in boost pressure-relief valve.

-Tapered shaft option for direct drive shaft yoke installation
