摘要： 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.

摘要： A pump features a liquid sensing device (LSD) in combination with a housing. The LSD senses the level of a liquid collecting outside the pump and turns the pump on/off for pumping the liquid. The housing includes a housing wall to contain the LSD. The housing wall has an outside wall surface with an outside sensing surface. The housing includes an inside mounting structure to mount the LSD inside the housing in relation to the outside sensing surface. The outside sensing surface has ribs extending or projecting outwardly away from the outside wall surface in order to prevent an object from being stuck on the outside sensing surface, and allow the LSD to sense the level of the liquid collecting outside the pump and touching the outside sensing surface, reducing a malfunction of the pump due to the object contacting the outside sensing surface.

摘要： 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.

摘要： A modular pump features a gas-control-and-drive-unit (GCDU), a cartridge-style-pumping-module (CSPU) and a retainer clip (RC). The GCDU includes a GCDU-housing to receive/provide gas to a gas-passageway causing a GCDU-force in one direction; an actuator-rod-and-slide-valve-arrangement (AR/SVA) to respond to a CSPM-force and exhaust the gas from the GCDU-housing causing a GCDU-exhaustion-force in an opposite direction; and a GCDU-coupling-member. The CSPM includes a CSPM-housing to receive a fluid to be pumped, and a piston-and-dual-diaphragm-arrangement (PDDA) to respond to the GCDU-force, provide the CSPM-force and pump the fluid from the CSPM, and to respond to the GCDU-exhaustion-force and pump the fluid from the CSPM. The CSPM-housing includes a CSPM coupling member to detachably couple to the GCDU-coupling-member. The RC detachably couples a piston of the PDDA and an actuator rod of the AR/SVA, so the CSPM attaches/detaches from the GCDU using a three-step process for field replacement using the RC.

摘要： 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.
