Abstract: An automatic self-driving pump system features a pump/motor/drive detector and an automatic self-driving and control design/setup module. In operation, the pump/motor/drive detector receives sensed signaling containing information about a pump/drive for operating in a hydronic pump system, e.g., stored in and sensed from a signature chip or barcode installed that can be scanned by a scanner, and provides corresponding database signaling containing information about parameters for providing automatic pump control design, setup and run to control the pump/drive for operating in the hydronic pump system, based upon the sensed signaling received. The automatic self-driving and control design/setup module receives the corresponding database signaling, and provides control signaling containing information for providing the automatic pump control design, setup and run to control the pump/drive for operating in the hydronic pump system, based upon the corresponding database signaling received.

Abstract: A pump features an impeller having a rotating disk with a front side and a back side. The impeller is arranged to rotate on a shaft with the front side nearest an inlet and the back side nearest a motor housing, so as to provide a main flow of liquid being pumped and a rear impeller flow of the liquid being pumped in an area between the back side of the impeller and the motor housing. The back side has a spiral-shaped vane configured to constantly sweep, and expel any debris from the area between the back side of the impeller and the motor housing. The spiral-shaped vane is formed as a curve that emanates from a central point defined by an axis of the impeller and gets progressively farther away as the curve revolves at least one complete revolution around the central point or axis.

Abstract: Apparatus for providing liquid from a reservoir of liquid contained in a vehicle/vessel or other equipment, featuring a pump for pumping liquid having a pump housing outlet nozzle; and a back flow preventer assembly having an inlet end to couple to the outlet nozzle, having an outlet end to couple to an outlet hose for connecting to an outlet exiting a wall of a vehicle, vessel or other equipment, and having a duckbill-type check valve to provide liquid being pumped in one direction from the reservoir of the vehicle, vessel or other equipment to the outlet exiting the wall of the vehicle, vessel or other equipment via the outlet hose, and also configured to prevent residue liquid left in the outlet hose from flowing back into the pump and returning to the reservoir once the pump has completed pumping if the outlet exiting the wall of the vehicle, vessel or other equipment is above the outlet nozzle, so as to prevent on an on/off oscillation of the pump depending on the volume of residue liquid left in the outlet hose.

Abstract: Apparatus, including a pumping system, is provided featuring a pump and a control circuit. The pump has an impeller housing configured with a slit at the top for trapped air to leave the impeller housing once the pump has been submerged. The control circuit is configured to cycle the pump on and off for a predetermined number of cycles so that the trapped air will float to the top and be expelled out the slit when the pump is cycled off. The control circuit is configured to leave the pump on after the predetermined number of cycles.

Abstract: A system features a controller having a signal processor configured to: receive signaling containing information about a liquid level of a gas infused liquid in a liquid/gas infusion tank/vessel, one or more gas input characteristics of a gas provided to the liquid/gas infusion tank/vessel, and one or more liquid input characteristics of an incoming non-infused liquid provided to the liquid/gas infusion tank/vessel; and determine corresponding signaling containing information to control a pump that provides the incoming non-infused liquid to the infusion tank/vessel on demand each time a beverage is dispensed with the gas infused liquid from the liquid/gas infusion tank/vessel and to maintain a desired liquid level and target equilibrium gas pressure in the liquid/gas infusion tank/vessel at a given temperature.

Abstract: A drain or sump box features a combination of a housing, a pump, a float switch and a deodorant bar retainer. The housing may include a housing floor and a wall structure attached thereto and configured to receive and contain waste water. The pump is arranged in the housing to respond to signaling for pumping the waste water from the housing. The float switch is arranged in the housing to sense the level of the waste water and provide the signaling to turn the pump on when the waste water exceeds a certain level. The deodorant bar retainer is arranged in the housing in the housing to receive and retain a deodorant bar for preventing, reducing or masking waste water odor and associated bacteria causing the waste water odor.

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.
