  1. Galvanised Access Cover
  2. GRP Tank
  3. Inlet Pipe
  4. High Level Alarm Float
  5. Control Panel
  6. Quick Release Coupling
  7. Isolation Valve
  8. Non Return Valve
  9. Submerged Pump with Integral Float

As the level of the liquid rises in the chamber the integral float on the pump is activated, the pump starts and pumps the liquid out of the chamber until the pump float drops and the pump turns off.

The level of the liquid will again rise and the above sequence is repeated.

If the pump fails to pump, the liquid level will rise to activate the high level float and the high-level alarm light will be illuminated.
