The facts are clear and so are the choices. Franklin Electric's Pumptec family provides the high performance pump protection you need deep down in the well. Designed to monitor motor load and supply voltage and to shut down the pump to prevent damage, Pumptec family products protect you water system investment. Pumptec, QD Pumptec and Pumptec-Plus are the only single-phase load monitoring devices designed specifically for Franklin single-phase motors. They cover a broad range of ratings and fault conditions.
Application: Protects Franklin Electric 2 wire and 3 wire single phase submersible pump motors against: Low voltage, Drop in water level, Low yielding well, air or gas locked pump, clogged well screen, broken shaft or coupling and worn pump parts
When the water level drops too far, the motor will start to run faster, due to less load on the pump. When the pump motor changes speed, it affects the amp load on the motor leads. Pumptec will interrupt power to the motor whenever load drops below a preset level. After a preset time, Pumptec will restart the motor. Pumptec can be set to stay off from 2 minutes up to 90 minutes, when tripped, or can be set for manual reset. This allows your water well to recover to a safe operating level before restarting the pump motor. When Pumptec detects that the motor load has dropped below a preset level for over 4 seconds, Pumptec will interrupt power to the motor and display the tripped condition light. To reset the Pumptec manually, turn off the power supply for 5 seconds, then turn it back on.
