MODEL 125-7

MODEL 125-7


The Model 125-7, primarily designed for use with centrifugal booster pumps, can also be used on well pumps with relatively shallow lifts where the pump design permits starting against a closed valve. Because of its lift check feature, the 125-7 is ideally suited to those pumping applications where little or no back flow can be tolerated.


  • Eliminates surges associated with starting and stopping the pump
  • Pump starts against a closed valve that then gradually opens at a controlled rate
  • Valve gradually closes at a controlled rate while pump continues to run
  • Pump stops when valve is fully closed
  • Integral lift check feature closes valve immediately on power failure
  • Separate adjustable opening and closing speeds
  • Can be maintained without removal from the line
  • Factory tested
