For use with our Franklin Electric Cistern Pump or any well/water pump, this device can be wired in between the pump and the electric panel and is used to detect abnormal changes in pump motor activity (i.e., when well or cistern is dry) and is therefore used to protect the pump motor. We HIGHLY recommend the PumpSaver in situations where you have a low-producing well and are trying to create a well back-up system or reservoir. Contact us for more information or for system design.
The Pump Saver & Overload Relay 111-3R-L (115 volt, 1⁄3 to 1hp) single-phase PumpSaver® relay protects pumps from dry-well, dead-head, jammed impeller, rapid-cycling, and overvoltage/undervoltage, whether the pressure switch is mounted before or after our unit.
A calibration process allows the relay to be calibrated to your specific pumping application, thereby reducing the possibility of false or nuisance tripping. A proprietary microcontroller based voltage, power factor and current-sensing circuit constantly monitors for power fluctuations, overcurrent and underload conditions. When an abnormality, such as loss of suction, is detected, the relay deactivates its output relay and directly disconnects the pump motor and begins its user-selectable “Restart Delay” (dry-well recovery) timer. When the timer expires or power is removed and reapplied, the unit reactivates its output relay and allows the pump to turn back on.
An infrared LED communicates directly with a hand-held diagnostic tool called the Informer (sold separately). The Informer displays parameters including calibration points, trip points, run time and last faults.
This Pump Saver comes with a NEMA 3R enclosure.
