The most powerful pump in the Hughes range, the HPS5000 has a specification producing a heavy duty capability for dealing with the more difficult problems in industry and shares critical components with the smaller HPS3000 pump. The 5 cylinder build has an inherently smooth flow characteristic – flow variation is reduced to less than a third when compared to the more common triplex arrangement.
The close coupled, gear driven power end has pressure lubrication, filtration and oil cooling. An SAE 1 adaptor housing is available enabling the pump to be flange mounted to a diesel engine flywheel housing ensuring extremely compact, perfectly aligned installations and enclosing all moving parts.
For maximum hydraulic efficiency, the in-line valve arrangement is designed to minimise the internal losses and prevents the adverse effects of cyclic stress within the head block, while allowing all working components to be easily removed on site for service.
This improved design is capable of high pressure to high volume with outstanding seal, plunger and valve life.
