* The pressure ratio is driven piston/hydraulic plunger ratio.

* The outlet pressure based on air driven pressure is 8Bar (116psi). (It is estimation of maximum allowable pressure.)

* The rate of flow based on the air driven pressure is 6Bar (87psi) and the outlet pressure is 0 Bar. (It is approximate flow value.)

* The mininum air driven pressure is 3 Bar (43.5psi). 



Advantage of our pump



1.  Costing savings:  An alternative to the purchase of High Pressure compressor ,our air driven liquid are Compact and Require no electrical or mechnical drive connections ,Are powered by the same air that they amplify and can mounted in any position 


2.  High Flow rates at High pressure:  When High flow rates at high pressure are needed ,the Air Liquid pump can charge a receiver to an even higher pressure level ,thus storing a volume of  air aviable for rapid release at a constant pressure through a pressure reducing valve 


3. Safety Operation :  Safe Pneumatic Operation-No Heat, Flame or Spark  Rish and No need electricity .

Cheapest Miniature air driven liquid pump It Can be used for pressure testing ,cylinder positiong for valves  ,super critical fluid extraction for food preservation .Chemical metering /Injection ,hydrostatic testing for liquid pump .







We adopt the advanced material Expansible Polystyrene(EPS) as inside packaging , which is more secure and eco-friendly than common packing. Master cartons outside.






By sea Cheapest but longest option 18~30 days by sea delivery, best for large quantity order.
By air More expensive than sea delivery, But cheaper than express 5~7 days by air to airport.
By express Door to door service,the fastest and most expensive one, 3~6 days by express.
