A submersible pump, comprising: a casing, having accommodated therein a pumping unit and a drive unit for driving the pumping unit; a base, defining a pump inlet; and a float control unit. The float control unit comprises: a float, having at least one magnet; and a float chamber housing, defining a float chamber in which the float is movable up and down. The float chamber has at least one opening which connects the float chamber with an external environment. At least part of the float chamber housing is movably or removably attached to an outer wall of a casing of the submersible pump.

A pump having a drive unit with an electric motor, a hydraulic unit connected to the electric motor, and an integrated control unit operatively connected to the electric motor and configured for monitoring and controlling the pump. An integrated pressure sensor, connected to the control unit, has a fixed reference pressure. The control unit determines a liquid level of a liquid surrounding the pump based on a relation between an actual value of the pressure sensor and a reference value. A method for calibrating the pump comprises initiating pumping, continuing pumping until the liquid level is equal to a predetermined calibration level, determining the actual pressure value when the liquid level is equal to the predetermined calibration level, and calibrating the pump by setting a new reference pressure value corresponding to the actual pressure value.

A centrifugal pump pet water fountain is provided which includes a bowl defined by a peripheral wall extending upwardly from a floor. The bowl is configured to hold water. The housing divides the basin into a drinking basin and an interior basin. The housing includes an upright sidewall extending from a floor and a cap. The housing also defines an elevated water reservoir with a spout. A rotating cone is positioned within the housing and driven by a motor. The cone has a water inlet and a top opening adjacent the cone top opening. During operation, the rotation of the cone forces water to climb the interior surface of the cone through centrifugal force, where the water is deposited within the reservoir and returned to the drinking basin through the spout.

A water transmission device and a washing machine including the same. The washing machine includes a water transmission device configured to discharge water in a washing tub, wherein the water transmission device includes a filter case which is disposed under the washing tub and accommodates a filter, and into which the water in the washing tub is introduced, a pump case connected to the filter case and accommodating an impeller configured to suction the water in the filter case and discharge, a motor configured to rotate the impeller, a suction hole through which a side portion of the pump case facing a center of the impeller and a side portion of the filter case, and an outlet which is open downward from a lowest end inside the pump case and communicates with a water discharge pipeline.

The utility model relates to a household submersible pump, which comprises a pump base, a pump body and a signal light assembly, wherein the pump base is provided with a water outlet, a water inlet and a first filter screen; the pump body has an inner housing having an inner electrical chamber equipped with a circuit board therein and a front mount, and an outer housing having a front guiding seat; the signal light assembly comprises a signal light connected to the circuit board and a light guiding column with a waterproof seal ring embedded therein; the light guiding column is able to be rotated from a first state in which it can be inserted into the front mount through the front guiding seat to a second state in which it is locked in the front mount, and is set to be able to export the light emitted from the signal light to the outside of the outer housing. The utility model not only achieves an outward propagation of light to indicate the status of the pump but also achieves an IPX8 level waterproof.

The invention, comprises a pumping apparatus, system and method for increasing the flow of the in a first direction to boost liquid flow and in a reverse second direction to remove blockages and/or self-clearing, with operation having an rotor/impeller that can use a shredder and/or shearing action utilizing blades for processing to pass solids, debris and other things to prevent clogging and/or self-cleaning of the unit.

Improved systems and methods for cleaning a filter are described, including apparatuses that include a built-in mechanism for cleaning a filter screen. The system can include a brush mounted in contact with a filter screen, adapted so that the brush can be moved to clean the filter screen. In some versions, the brush rotates with an axis of rotation perpendicular to a plane defined by a substantially planar filter screen. In other versions, the brush is adapted to be moved by a gravitational force along a surface of a filter screen upon removal of a pump housing from a pump well. In still other versions, a substantially cylindrical brush is mounted nested with a substantially semi-cylindrical filter screen, and the brush can be rotated while in contact with the filter screen and with an axis of rotation aligned with a longitudinal axis of the filter screen.

A vertical multi-stage pump includes a rotation shaft extending in a vertical direction, a plurality of impellers fixed to the rotation shaft, a multi-stage pump chamber accommodating the plurality of impellers and comprising a suction port for a first-stage impeller at a lower end, a lower casing comprising a suction nozzle extending in a horizontal direction and forming a communication space communicating the suction nozzle and the suction port, and an inner cylinder member interposed between the multi-stage pump chamber and a lower casing and expanding the communication space in a vertical direction.

A debris trap for capturing debris flowing in a stream of liquid, the debris trap includes a housing, a fluid inlet channel in connection with a space in the housing, a fluid outlet channel in connection with the space, the fluid outlet channel comprising a fluid outlet port, a float member, a guide element configured to guide movement of the float member when a liquid level in the space changes when in use, a stopper in connection with the fluid outlet port configured to stop the movement of the float member when the liquid level in the space raises, the fluid outlet port which, when the float member is against the stopper, remains partially open and the float member, when brought against the stopper, form a fluid communication path with a reduced area, which restricts the size of the debris capable of flowing through the outlet port.
