1. A pump assembly comprising: a permanent magnet motor having a stator with coil windings; a rotor assembly having a shaft, and an impeller attached to the shaft, the shaft being driven by the stator, the impeller driving fluid through the pump assembly; and a control module having a controller and a user interface, the controller measuring characteristics of the stator, the controller determining at least one of the flow rate and the pressure of the fluid moved through the pump assembly based on the characteristics measured, and the user interface being configured to display an output representative of at least one of the flow rate arid the pressure of the fluid.
