Welcome to HEYPAC

Manufacturers of air driven hydraulic pumps, hydraulic power units, air driven fluid pumps, pressure boosters and intensifiers offering pressures up to 840 bar (12,000psi).

Suppliers of a full range of accessory products including zero leak directional control valves, pressure reducing valves, reservoirs, pulsation dampeners, fluid and air filters.

Maximum hydraulic power 1.5kW (2.0hp)

The GX pump and the EGX ATEX version are available in fluid-to-air ratios of 2.5:1 to 120:1. Maximum fluid pressure is 780 Bar.

Various mounting configurations are available which include a wall mounting bracket and tank mounting flange.  The pump can be mounted on our 2.5, 4.5, 10 and 30 litre reservoirs.  We also manufacture custom reservoirs to order, in various capacities and materials.
The pumps can be supplied with directly mounted CETOP03/D03/NG6 valve manifolds.

'Q max' is defined as the maximum pump flow at 250 cycles per minute - intermittent duty only. One cycle is defined as one down stroke plus one up stroke.                                                   

'Q max average' is defined as the maximum average allowable flow over the complete system operating cycle including both periods of pressure holding (stall condition) and fluid delivery.

Maximum hydraulic power 0.37kW (0.5hp)

The K2R pump and the EK2R ATEX version are available in fluid-to-air ratios of 2:1 to 80:1. Maximum fluid pressure is 680 Bar.

Various mounting configurations are available which include a wall mounting bracket and tank mounting flange. The pump can be mounted on our 2.5, 3, 10 and 30 litre reservoirs. We also manufacture custom reservoirs to order, in various capacities and materials.
The pumps can be supplied with directly mounted CETOP02/D02/NG4 and CETOP03/D03/NG6 valve manifolds.
