Low profile pump with the ability to be mounted in various configurations

A pumping system comprising:

• a pumping chamber configured with a central portion having an outlet, and configured with a tubular coupling end portion having inwardly flexible portions, each inwardly flexible portion configured with a respective outwardly extending raised rim;
• and
• a mounting base including a circular portion having an inner circumferential wall with an inner circumferential recess configured therein to receive and engage the outwardly extending raised rims of the inwardly flexible portions of the tubular coupling end portion of the pumping chamber, so that the pumping chamber is rotationally coupled to the mounting base for 360° rotation;
• the pumping system having a motor, pump and electronics assembly with an impeller and a motor for rotating the impeller;
• and the mounting base and the motor, pump and electronics assembly being coupled together using a detent and slot arrangement so that the impeller extends into the pumping chamber,
• the motor, pump and electronics assembly having a housing configured with at least one outwardly extending detent formed or configured thereon, and the mounting base having a circumferential wall configured with at least one inwardly extending slot for receiving the at least one outwardly extending detent of the housing for coupling together the mounting base and motor, pump and electronics assembly;
• the pumping system having a switching assembly having a printed circuit board assembly with a water level sensor configured to respond to a water level and turn the motor in the motor, pump and electronics assembly on and off, the switching assembly arranged in a housing part of the motor, pump and electronics assembly;
• the at least one outwardly extending detent having two diametrically opposed outwardly extending detents formed or configured on the housing, and
• the at least one inwardly extending slot having two diametrically opposed inwardly extending slots for receiving the two diametrically opposed outwardly extending detents of the housing for coupling together the mounting base and the motor, pump and electronics assembly in at least two rotational orientations that differ by 180°, including
• a first rotational orientation so that the water level sensor is located at a higher height in the housing part for providing a higher water level sensing setting, and
• a second rotational orientation so that the water level sensor is located at a lower height in the housing part for providing a lower water level sensing setting.
