US Patent Granted for Reciprocating Pump Drive Mechanisms

Patent number US 10,371,132 B2 has been granted to PeopleFlo for two variations of a mechanical drive mechanism for reciprocating pumps.  In both variations, unique linkage and a one-way clutch transform rotary motion from the driver (usually an electric motor) into reciprocating motion to drive the pump.  Both versions also include a provision that allows for simple adjustment of the pump’s stroke rate, providing adjustable variable flow without changing the driver speed.

“This enables an electrically-driven diaphragm pump to behave much like a traditional air-powered pump, except with dramatically higher efficiency” explained Dan Turner, co-inventor.
