Series QPC Quadraplex Pump Controller is used where 4 pumps need to alternate to provide equal run time on each. By offering 5 inputs, controller allows 4 outputs to operate properly even if one input fails to open or close. It has 4 LED indicators that show load energized by SPST output contacts and is available in sequence-on-simultaneous-off and first-on-first-off configurations. In either, lead load position is advanced to equalize run time on each pump.

Dwyer Instruments, Inc., the preferred source for your complete range of practical and affordable instrumentation, has just released the NEW SERIES QPC QUADRAPLEX PUMP CONTROLLER.
The Series QPC is used where four pumps are required to alternate to provide equal run time on each. Alternating loads allows for equal wear on all pumps lengthening their operation life. The Series QPC has five inputs allowing the four outputs to operate properly even if one of the inputs fails to open or close. Four LED indicators show the load that is energized by the SPST output contacts.
The QPC is available in two sequence configurations: sequence-on-simultaneous-off (SOSO) and first-on-first-off (FOFO). In either sequence, the lead load position is advanced to equalize run time on each pump. An inrush delay on both models reduces line sags by preventing multiple loads from energizing simultaneously.
