Abstract: Apparatus is provided featuring a switch-mode power supply (SMPS) having a power circuit component in combination with a SMPS controller. The power circuit component may be configured to provide power to a pump that provides fluid from a container to some other device, including an appliance. The SMPS controller may be configured to receive signaling containing information about at least one control parameter selected from a group including a pressure at an outlet of the pump, a fluid level in the container and the temperature of a motor of the pump, and also may be configured to shut off the power provided to the pump based at least partly on the signaling received so that the power circuit component substantially does not draw power and heat up when the pump is shut off.

Abstract: A disposable pump head and canister assembly is provided having a disposable pump head having an upper housing with an input port and an output port, and being configured to be engaged to a motor so as to pump fluid into the input port, through the disposable pump head, and out the output port, the upper housing configured to couple to a support plate via a plurality of upper housing flexible tabs that snap fit to corresponding structure of the support plate and configured to be frictionally engaged to a motor so as to pump fluid into the input port, through the disposable pump head, and out the output port; and a canister having an exterior wall portion, a cover and a latching arrangement, where the exterior wall portion is configured so as to form an interior cavity dimensioned to receive the disposable pump head, and where the cover is configured to close and be latched to the exterior wall by the latching arrangement so as to frictionally engage the disposable pump head and the motor.

Abstract: The present invention provides a pump, comprising: a disposable pump head having an input port and an output port, and being configured to be frictionally engaged to a motor so as to pump fluid into the input port, through the disposable pump head, and out the output port; and a canister having a cover and a latching arrangement, and configured with an interior cavity dimensioned to receive the disposable pump head, the cover configured to close and frictionally engage the disposable pump head and the motor. The cover has a compressible member, like a pad, dimensioned so as to push a top surface of the disposable pump head so as to frictionally engage the disposable pump head and the motor. The cover may be arranged on a hinge. The latching arrangement may comprise a part for grabbing a lip of the cover.

Abstract: 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.
