The versatile HPS650 covers a wide range of flow rates and pressures. It has elements in common with the HPS400 and HPS850 pumps. The direct coupled power transmission output has a splash lubrication system with oil cooling. SAE adapter housings are available, allowing the pump to be coupled with the flywheel of an internal combustion engine 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. Treated ceramic pistons extend the life of the seals. The improved design, with seals, plungers and valves, withstands high pressures at high flow rates.
