Air Driven Pumps and Power Packs

The HEYPAC pumps is a double acting, free piston, compressed air driven hydraulic pump of infinitely variable delivery for general use wherever a compressed air sypply is available.

  • Energy efficent: pimp will cycle automatically according to system demand and stall zero flow conditions with minimal energy consumption.
  • Infinitely Variable Flow and Pressure: The output flow and pressure depend upon the intensification ratio relative to the air supply
  • Fluid pressures from 5 to 680 bars
  • ATEX Approval Ex II 2G D, c T6
  • Wide range of Fluids: Mineral oils, Vegetable oils, High water-based fluids, water glycol solution, water in oil emulsions, greases, phosphate esters, silicate esters, liquified gases, water...
