Thanks to its robust design, the HPS1000 ultra-high pressure pump is an excellent solution, in terms of performance, to solve the industry’s most demanding problems. With a maximum pressure of 1400 bars, a power of 75 kW and a maximum flow rate of 177 L/min, this pump supplied by HUGHES can be adapted to different types of industrial applications thanks to its robustness.

The mechanical part (which includes the crankshafts), has a forced lubrication system, with filtration and oil cooling. SAE adapter flanges are available, allowing the pump to be coupled with the flywheel of a combustion or electric motor. The design of the head is optimized, with the valves positioned in line, to avoid cyclic metal hardening and to facilitate maintenance. The treated ceramic pistons extend the life of the seals.

The improved design, with seals, plungers and valves, withstands high pressures at high flow rates.
