Abstract

See full text

A liquid transfer pump comprises a bellows-type chamber retractable and extendable by a reciprocating drive. The pump is fed by feed stock inflow controlled by a flexible tubular pinch-type valve, and propelled out of the chamber through an identical pinch-type valve. Quick pneumatic relief valves mounted directly on the pinch-type valves ensure instantaneous opening of the pinch-type valves thereby regulating liquid flow. Synchronous regulation of pump cycles is maintained by computer or microprocessor control.
