With pressures approaching 10,000 psi, Heypac is the world leader in the development, manufacture and marketing of a range of the most advanced air driven fluid pumps and hydraulic power units.

The Heypac is a double-acting, free piston, compressed air driven hydraulic pump of infinitely variable delivery for general use wherever a compressed air supply is available. The pump will cycle automatically according to system demand and stall under zero flow conditions with minimal energy consumption. The output flow and pressure depend upon the intensification ration relative to the air supply pressure and volume.
