External pump chamber, lincolnshire sewage treatment

If the location of the Diamond sewage treatment plant is on an incline, in a high water table area or a long distance away from the designated discharge point (ie: soakaway/water course/ditch) the final effluent may require pumping. Contact Us for help sizing your pump station.

The Diamond range can be specified with an External Pump Chamber (EPC) which can deliver up to 100 litres per minute of effluent at a head of 4m. 

The EPC can be simply retro-fitted and is easy to maintain.

How does the EPC work?

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 beacon will be illuminated.
