Seat Valve Piston Pump HSP

Transports Highly Viscous Materials with a Low Content of Foreign Bodies

The HSP (hydraulic seat valve pump) is an oil-hydraulic piston pump with hydraulically actuated seat valves. It is used to transport highly viscous materials with a low content of foreign bodies at smaller particle sizes (diameter < .2” (5mm)). All moving parts are connected to a central grease lubrication system in order to increase the lifetime of the components.
