Abstract: Apparatus features a microcontroller configured to: receive signaling containing information about a measured change of a magnetic field created by a magnetic circuit driving a motor; and determine corresponding signaling containing information about the speed of rotation of the motor, based upon the signaling received. The microcontroller provides control signaling containing information to control the operation of the motor, including where the motor control is used to control the flow of fluids from a pump. A Hall Effect Sensor is used to sense the magnetic flux and provide the signaling in the form of a feedback signal for implementing motor control. The motor housing has a slot, the Hall Effect sensor is mounted external the motor housing over the slot, and a ferromagnetic bridge is arranged over the Hall Effect sensor to close the magnetic circuit and cause more flux to go through the Hall Effect sensor.

Abstract: The present invention provides a pump cartridge, which is directly connected in-line with one or more filter cartridges in a mounting bracket. It may be paired with an accumulator tank for a pump version, and with no accumulator tank for a smart pump version. The inline design reduces the size of the system, the amount of connections, and the amount of hose required to install the system, which in turn reduces the space required for installation, the number of potential leak paths, and the likelihood of failure of the system due to issues with the hose.

Abstract: A pump has a housing that includes an inlet to receive a liquid to be pumped, an outlet to provide the liquid being pumped, a pumping chamber between the inlet/outlet; and a motor shaft to rotate in the pumping chamber. The impeller is arranged on the motor shaft, includes radially curved vanes to rotate inside the pumping chamber to pump the liquid from the pumping chamber to the outlet; and includes anti-airlock vanes formed as a set of axially curving vane extensions that extend along the axis of the shaft, rotate with one part inside the pumping chamber, protrude through the inlet and rotate with another part outside the inlet for submerging in liquid to be pumped underneath the pump, draw the liquid through the inlet into the pumping chamber, and provide the liquid to the radially curved vanes to generate pressure to force entrapped air from the pumping chamber.

Abstract: A pump includes a liquid housing having a liquid chamber with a piston/diaphragm assembly arranged therein that responds to a suction stroke and draws liquid into the liquid chamber, and responds to a pressure stroke and provides liquid from the liquid chamber; and a gas housing having a slide valve assembly separating first and second gas chambers. The slide valve assembly responds to a suction-to-pressure-force at the suction stroke conclusion, changes from a suction-to-pressure stroke state, provides gas from the first to second gas chamber through the slide valve assembly, and provides the pressure stroke so liquid passes from the liquid chamber; and responds to a pressure-to-suction-force at the pressure stroke conclusion, changes from the pressure-to-suction stroke state, provides gas from the second chamber through the slide valve assembly, and provides the suction stroke so liquid is drawn into the liquid chamber.

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 features: A motor having a front end bell (FEB) with a coupling portion having twist lock style (TLS) connections with locking portions, and an outer surface with a detent; and a pump head (PH) including a PH portion having a PH coupling portion with corresponding TLS connections and corresponding locking portions with locking stops. The PH portion has an outer surface having a threaded orifice. The TLS connections couple together when the FEB and PH coupling portions are pushed together. The locking portions engage when the FEB and PH coupling portions twist together about the longitudinal axis of the pump. The locking stops abut against the locking portions to stop the FEB and PH coupling portions from twisting further, so the detent and the threaded orifice align to receive the LP, locking the motor and PH together.

Abstract: The pump has a pump body having a pump body portion with a vent hole to allow air entrapped in the pump body to bleed out to atmosphere and allow liquid to fill the pump body in order to get the pump running, and also includes a tab receiving portion having a rim defining an opening; and a pump/strainer assembly that includes a base with slots/openings formed therein to receive and strain liquid to be pumped, and includes a strainer retaining tab with a raised rim to be received in the opening of the tab receiving portion and circumferentially engaged by the rim of the opening to hold together the pump/strainer assembly and the pump body. The at least one tab receiving portion and the strainer retaining tab are dimensioned to conceal the vent hole and substantially prevent the liquid from bleeding through the vent hole and squirting outside of the pump body when the pump is running.
