Pump over-run systems

Harrier pneumatics has a vast range of pump overrun systems to integrate with any plant room set up you may require.

Pump overrun will shut down a diaphragm pump when it starts to speed up due to lack of product, it can also be sued as a low level shut off valve, the pump overrun valves have an integrated flow control of pump speed.

We have the following variations of the pneumostop systems

(pump-overrun prevention valves):

  • ¾” bsp with a manual start button
  • ½” bsp with a manual start button
  • ½” bsp with air pilot start and air pilot stop and manual stop and start buttons suitable for setting up.
  • Remote start, twin button version available for air piloted start/stop valves
