发明名称 Composite pumping system
摘要 An article transfer pumping system combining the effects of a jet pump and an air lift pump to minimize article damage while increasing lift capability and overall system efficiency. Air lift pump placement adjacent the pump inlet aerates the rising column of water with articles such as fish, even large salmon, being raised by the jet pump, whereas jet pump placement adjacent the discharge end of the conduit increases pump efficiency.
