A pump system or device is provided for removing water from a pool cover or sump, featuring a controller configured to respond to a signal containing information about the ambient temperature in relation to a pump and to provide a controller signal containing information to control the operation of the pump based at least partly on the ambient temperature. The pumping system or device me be configured to include some combination of the following: temperature sensing, including a Thermistor, to change control logic at temperatures below a specific level (e.g. below 35 degrees F.); the initiation of impeller cycling at low operating temperatures to avoid ice formation in the impeller cavity and/or hose, but not for level sensing; the use of temperature feedback to turn off pump at low temperatures that may result in damage to the system; the addition of control logic to ignore torque increases due to contamination or flow-back Inclusion of soft-start of motor to reduce stress on impeller/motor; the option to connect Garden-style hose with an integral heating element to avoid freezing; a heating element to receive power from the pump via, e.g., a plug connector, where power to the heating element is supplied only when the temperature device is activated at some specified setting; the addition of a temperature sensor to render the pump inoperative if the temperature should fall below a set point (freezing); and/or the use of a field effect level sensor, such that the temperature sensing is substantially independent of the level sensing device.

A pump motor is disclosed. The pump motor includes a case; a socket part disposed in a portion of the case and provided with a terminal part thereinside; and a cover part detachably coupled to the case and configured to open and close the socket part, wherein the socket part includes a moisture blocking member configured to block a gap between the case and the cover part.

A drain pump includes an impeller, a rotor configured to rotate the impeller, a stator, a first housing that defines a rotor accommodating portion, a second housing that is coupled to the first housing and that defines together with the first housing a motor accommodating space that accommodates the stator, a connector that extends from the stator and that has a contact surface configured to connect to a power source and exposed to an outside of the motor accommodating space through at least one of the first housing or the second housing, and a connector cover portion that is located at at least one of the first housing or the second housing to cover the connector and that has at least one side surface opened to expose the contact surface of the connector to the outside of the motor accommodating space.

A circuit board includes a circuit board main body including a first through hole and a second through hole, a first inlay member inserted into the first through hole, and a second inlay member inserted into the second through hole. A first end surface of the first inlay member includes a first end portion on the side of the second inlay member, a second end portion on the opposite side of the second inlay member, a first area including the first end portion, and a second area including the second end portion. A first end surface of the second inlay member includes a third end portion on the side of the first inlay member, a fourth end portion on the opposite side of the first inlay member, a third area including the third end portion, and a fourth area including the fourth end portion. The circuit board further includes a first resist provided in the second area, and a second resist provided in the fourth area.

A pump assembly includes an electric motor with a printed circuit board carrying a controller, a pump driven by the electric motor, a housing surrounding the printed circuit board, and a plug connector which is fixed to an outside of the housing by a flange. The plug connector covers an opening of the housing and includes contacts directly electrically contacting the printed circuit board and passing through the opening of the housing. The connector includes a pressure compensator including a sintered filter to vent the housing.

A method for producing a submersible motor pump for pumping waste water and/or sewage includes a cylindrical pot-shaped housing forming an inner space between an open base surface and a cover surface axially opposite the base surface, including a connector opening provided in the pot-shaped housing, a motor provided in the inner space and comprising a cylinder-like stator comprising a plurality of windings and a first connector connected to ends of the windings, in particular oriented towards the cover surface and provided with at least one radially resilient latching tab, including the steps of gripping the first connector from outside the pot-shaped housing through the connector opening, inserting the first connector from the inner space into the connector opening, and latching the at least one latching tab to the pot-shaped housing.

An improved an end cap assembly for a fuel pump is provided. The end cap assembly includes first and second brush caps herein that are overmolded onto first and second shunt wires to ensure a fluid-tight seal around the shunt wires without requiring heat staking, sonic welding, or melt flowing the end cap to the shunt wires. The brush caps are cone-shaped and include a snap-fit feature that retains the brush caps in place when the endcap assembly is transported prior to being assembled to a fuel pump body.

An electric pump includes: an impeller; a rotor connected to the impeller; a housing accommodating the rotor; divided iron cores surrounding the housing from an outside of the housing; divided coil bobbins respectively attached to the divided iron cores; divided coils respectively wound around the divided coil bobbins; and a bus bar unit including bus bars, wherein the housing includes a bottom wall portion directly or indirectly holding a shaft portion in a standing manner, the shaft portion supports the rotor for rotation, the bottom wall portion overlaps at least a part of the divided coils in an orthogonal direction orthogonal to an axial direction of the rotor, and the bus bar unit is conductively connected to the divided coils and is held by the bottom wall portion.

The present discloses a pump apparatus having a first pump and at least one controller. The at least one controller is suitable for generating a first control signal for controlling the first pump. The at least one controller is suitable for generating a second control signal for controlling operation of a second pump. The second pump is external to the pump apparatus. One or more pump connection port is provided in the pump apparatus for outputting the second control signal to the second pump. The present disclosure also relates to a vacuum system comprising a pump apparatus of the type described herein.
