  • Pump for transfer of liquids containing suspended solids
    Patent number: 9822770
    Abstract: 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.

  • PUMP FOR TRANSFER OF LIQUIDS CONTAINING SUSPENDED SOLIDS
    Publication number: 20140079573
    Abstract: A pump for transferring liquids containing suspended solids comprises a bellows-type chamber retractable and extendable by a reciprocating drive means. The pump is fed by feed stock inflow controlled by a flexible tubular pinch-type valve, and propelled out of the chamber through a substantially identical pinch-type valve. Programmed control means is inadequate to properly regulate volume of flow, and independently interventional means are disclosed to correct aberrant pump cycles.
