HIGH PRESSURE QUINTUPLEX PUMP
Extending the series of pumps from the highly successful HPS650, the more powerful HPS850 offers an increased range of flow rates. The standard 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 incorporates an oil circulation pump to assist in cooling. Standard adaptor housings are available enabling the pump to be flange mounted to a diesel engine flywheel housing or electric motor ensuring extremely compact and perfectly aligned installations.
For maximum hydraulic efficiency, the in-line valve pump head arrangement is designed to minimise the unswept volume.
This improved design is capable of high pressure to high volume with outstanding seal, plunger and valve life.
