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:
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.
Abstract:
An in-line gas liquid infusion smart system, featuring a controller having a signal processer configured to receive signaling containing information about parameters or settings related to dispensing a non-infused liquid and a gas-infused mixture of gas and liquid from a dispense point; and determine corresponding signaling containing information to dispense the non-infused liquid and the gas-infused mixture from the dispense point, and also containing further information about the parameters or settings for providing to a remote controller for controlling, monitoring or troubleshooting the in-line gas liquid infusion smart system, based upon the signaling received.
Abstract:
An air operated diaphragm pump is provided a housing having an orifice formed therein; a gas passageway configured to provide gas through the air operated diaphragm pump in order to pump syrup through the air operated diaphragm pump; a syrup passageway configured to provide the syrup through the air operated diaphragm pump when the gas is passed though the gas passageway, part of the syrup passageway configured in fluidic communication with the orifice of the housing with an inside pressure greater than an external pressure of the outside atmosphere when the syrup is provided through the air operate diaphragm pump; and an indicator arrangement configured or arranged in the orifice of the housing to communicate with the syrup passageway, and to respond or activate when a vacuum force exceeds a predetermined level and provide a visual indication when the syrup is no longer provided through the air operated diaphragm pump.
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.

Abstract:
A utility pump is provided featuring a housing and battery configuration, where the housing is configured with a series configuration of integral pumps, and also configured with a battery receiving portion having electrical terminals for receiving power for providing to the series configuration of the integral pumps, and where the battery has a protruding portion with corresponding electrical terminals configured to contact the electrical terminals to provide power to the series configuration of the integral pumps when the protruding portion of the battery is inserted into the battery receiving portion of the housing and rotated in one direction to an “ON” position, and also configured not to contact the electrical terminals when the battery is not rotated to the “ON” position.
