1. A pump system, comprising:

  • a pressure sensor, for providing a signal indicative of a sensed pressure;

    a controller, responsive to the signal indicative of a sensed pressure, and also responsive to electrical power, for regulating the electrical power based on at least the sensed pressure; and

    a pump unit, having a pumping mechanism and an electrical motor for driving the pumping mechanism, responsive to the regulated electrical power;

    wherein the pumping mechanism includes an inlet cavity and an outlet cavity on either side of a pumping structure, and the pressure sensor is disposed in the inlet cavity and/or the outlet of the pumping mechanism and is communicatively coupled to the controller.
