A home flood prevention appliance system includes controller circuitry disposed in a shroud above a cover of a sump basin, and a plurality of electrically operated sump pumps disposed in a lower portion of a structural frame positionable below the cover in the sump basin. The system also includes a water control actuator operable as a water main control device for a domestic water distribution network and a flow meter to measure the flow of municipal water supplied to the network. The controller circuitry configured to selectively energize the pumps to extract liquid from a sump basin based on a liquid level in the sump basin. The water control actuator controlled by the controller circuitry to shut off a municipal water supply to the domestic water distribution network in response to detection of a leak. Communication circuitry included in the home flood prevention appliance may wirelessly communicate.

An apparatus for monitoring of a pump includes a control module, and an error detection unit, wherein a support vector machine based module is provided that receives an estimated output quantity data value from the control module, processes the estimated output quantity data value to provide a processed estimated output quantity data value via the support vector machine, and supplies the processed estimated output quantity data value to the error detection unit instead of the estimated output quantity data value of the control module.

The present invention relates to a pump apparatus. The pump apparatus includes: an impeller (1) in which a permanent magnet (5) is embedded; a pump casing (2) which houses the impeller (1); a motor stator (6) having a plurality of stator coils (6B); a motor casing (3) which houses the motor stator (6); a bearing assembly (10) which supports the impeller (1); a vibration sensor (30) for detecting a vibration of the bearing assembly (10); and a controller (29) connected to the vibration sensor (30). The controller (29) calculates the rate of change in the vibration based on the vibration detected by the vibration sensor (30) and, when the rate of change in the vibration is higher than a predetermined threshold value, performs at least one of an operation to stop the supply of electric current to the motor stator (6) and an operation to trigger an alarm.

A kit for forming a fluid delivery system for a hydration system is also disclosed, as are various components of a hydration system.

A method for controlling a hydraulic pumping system that includes a centrifugal pump operating at a functional point. The method uses parameters of the centrifugal pump at the functional point and end-of-lines characteristics of the centrifugal pump to determine an updated Net Positive Suction Head Required, NPSH.sub.r, value.

Design solutions to mitigate the following four fatal flaws in the conventional pump system design; namely, (1) surprise pump-failure in single pump designs that can result in costly water damage; (2) the threat of fatal high voltage electrocution due to flooding; (3) grid power outage and no energy supply to support the needed pumping power that results in water damage; (4) foil odor from the standing water in the well after a period of low seeping rate with or without activated pumping. The principles described herein can completely mitigate the above four fatal design issues.

An appliance comprises an electric motor, a resistor or an inductor in electrical series with the motor, and a controller. The controller activates the motor, detects a voltage across the resistor or inductor while the motor is activated, and deactivates the motor or changes an amount of electric power supplied to the motor in response to a change in the detected voltage.
