Description

The versatile HPS650 model offers a wide range of flows and pressures and shares critical components with the HPS400 pump. The close-coupled, gear-driven power end has splash lubrication and oil cooling. SAE adapter housings allow the pump to be flange-mounted to a diesel engine flywheel housing or electric motor, providing extremely compact, perfectly aligned installations and surrounding all moving parts. For maximum hydraulic efficiency, the in-line valve arrangement is designed to minimize unscreened volume and allow for easy on-site removal of all operating components for service while avoiding the negative effects of cyclic stress within the head block. This improved design is capable of high pressure to high volume with exceptional seal, piston and valve life.

Maximum Pressure 1000 bar at 27 lpm
(14,500 psi at 6.0 igpm / 7.2 usgpm)
Maximum Power 48 kW
(65 hp)
