A pumping system having a main pump with a controller and a primer. The primer includes a vacuum source for drawing priming fluid into the pump, a vibratory fork liquid sensor which constantly senses for priming fluid, and a primer controller which connects the vacuum source as soon as the sensor does not sense priming fluid. The main pump controller initiates operation of the main pump substantially immediately upon receiving an indication that pumping is desired. A related pump operating method includes continuously sensing for the presence of adequate priming fluid, adding priming fluid to the pump whenever the presence of priming fluid is not sensed, and initiating operation of the pump substantially immediately upon receiving an indication that pumping is desired.
