Membrane pump driven by oil engine - has control valves to facilitate handling of slurries

摘要

The membrane pump is operated by a power unit (4) in the form of an oil engine driving a reciprocating piston (5) via a connecting rod. It can displace hydraulic fluid in a working space (6) against a membrane (7). The unit (4) is controlled by the action of valves and responding to pressure in the space (6) above the piston until the piston returns to zero. USE/ADVANTAGE - A pump for the delivery of abrasive and highly viscous slurries with high concentrations of solids offering a favourable working volume suitable for feeding filter presses.
