Abstract: Diaphragm pump features upper/lower diaphragm pumping assemblies (U/LDPAs) for pumping fluid and a manifold assembly arranged therebetween. The manifold assembly include a manifold body having an inlet with dual inlet ports and an inlet chamber to receive the fluid from a source; an inlet check valve assembly channel having an inlet duckbill check valve assembly (DCVA) arranged therein to receive the fluid from the dual inlet ports; U/LDPAs orifices having the U/LDPA arranged therein to receive the fluid from the inlet DCVA via first upper/lower manifold conduits and provide the fluid from the U/LDPAs via second upper/lower manifold conduits; an outlet check valve assembly channel having an outlet DCVA arranged therein to receive the fluid from the U/LDPAs; and an outlet having dual outlet ports and an outlet chamber to receive the fluid from the U/LDPAs and provide the fluid from the pump to a outlet source.

Abstract: A pump has a signal processor, including one forming part of a printed circuit board assembly, that receives signaling containing information about a voltage supplied to a motor to run a particular pump model, and also containing information about whether a current draw of the pump is lower than a predetermined low current level or is higher than a predetermined high current level; and determines whether to shut off the pump after a predetermined time, based on the signaling received. The signal processor provides control signalling to shut off the pump after the predetermined time if the current draw of the pump is lower than the predetermined low current level or is higher than the predetermined high current level, where the predetermined low current level and the predetermined high current level depend on the voltage being supplied to the motor to run the particular pump model.

Abstract: A pump system features a power adapter and a pump having a signal processor. The power adapter includes voltage settings that respond to a voltage setting by a user and provide a selected voltage. The signal processor receives signaling containing information about the selected voltage supplied to a motor to run the pump, and also containing information about whether a current draw of the pump is lower than a predetermined low current level or is higher than a predetermined high current level; and determines whether to shut off the pump after a predetermined time, based on the signaling received.
