This brochure introduces pneumatic driven air /Hydraulic boosters and Complete booster system.


These air liquid pump offer a flexible and efficient source for delivering high pressure liquids 


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 


2High 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 .


High Liquid flow 2-2.5 KW air compressor powered pneumatic driven hydraulic 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 .




Product Description


Item number

2AT Higest Liquid flow Haskel

Hydro-Pneumatic pump


Air driven
