Product Description

High quality model : WS-JS  10-200Mpa  High pressure air hydraulic

system ,hydraulic power  Unit ,  air hydrostatic testing machine

,pneumatic driven hydraulic power pack ,high pressure hydraulic test

bench , Portable closed cabinet air hydraulic pressure test bench  

  • Hydraulic Power Packs include WS-JS Model are complete hydraulic units ready for connection which are provided for generating operating pressures up to 190MPa.It is suitable for powering a variety of medium,such as oil, water or corrosive liquids.

  • As the pressure will be generated by means of a pneumatically operated pump.The electric connection will not be necessary.

  • To operate this system, the air driven liquid pump have to be equipped with the air control unit combined filter and water seperator, pressure-regulating valve,pressure control gauge as well as manual relieve valve.In this operation,the pump will be mounted to the stainless steel tank in the closed cabinet in a compact and space saving manner.Pressure gauges, valves and pressure regulators will be fitted on panel.

  • The desired operating pressure can be attained by adjusting the driving air pressure.When the driving air pressure and the output pressure reach the balance,the pump stops filling pressure and the output pressure stays at the preset value.

  • This hydraulic unit can be used for all kinds of pressure testing and test tools for research and test institutes or for other functions requiring a determined pressure.  

  • The configuration of the systems include :  air pressure gauge , outlet pressure gauge ( On the first line of the Panel )

  • The hand ball ( For control the on/ff the system ) , air pressure regulator valve ( for control the air pressure  )

  • Outlet needle valve ( for control the output of High pressure ) ,Uploading needle valve ( For releasing the high pressure ) ,it is on second line  and also include 1 set JS240 air driven liquid pump , 16 Liters hydraulic tank  inside of the cabinet  and related pipelines

Technical parameters   Driven piston diameter is : 125 mm
