High Pressure Triplex Pump
The versatile HPS650 model offers a wide range of flows and pressures and shares critical components with the HPS400 & HPS850 pumps.
The close coupled, gear driven power end has splash lubrication and oil cooling. SAE adaptor housings are available enabling the pump to be flange mounted to a diesel engine flywheel housing or electric motor ensuring extremely compact, perfectly aligned installations and enclosing all moving parts.
For maximum hydraulic efficiency, the inline valve arrangement is designed to minimise the unswept volume 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.
