1. A variable speed electric pump system comprising:
an impeller housing, said impeller housing defining an interior volume and having a water inlet and a water outlet;
an impeller disposed within the interior volume of said impeller housing;
a motor/electronics housing assembly connected in sealing engagement to said impeller housing, said motor/electronics housing assembly defining at least one cavity therein;
a brushless DC electric motor disposed within said motor/electronics housing assembly, said brushless DC electric motor having an output shaft projecting from said motor/electronics housing assembly into said impeller housing through a watertight seal, said output shaft connected to said impeller;
a microprocessor and a motor speed controller disposed within said motor/electronics housing assembly, said microprocessor in electric communication with said motor speed controller;
each of said microprocessor and said motor speed controller in electrical communication with an external direct current power source;
said motor speed controller in electrical communication with said brushless DC electric motor; and
a motor speed control apparatus located remote from said brushless DC electric motor and in electrical communication with said microprocessor and configured to send a motor speed signal to said microprocessor, whereby the motor speed signal from said motor speed control apparatus is received by said microprocessor which generates an output signal to said motor speed controller which then incrementally varies input voltage to said electric motor in response to said output signal.
