How our Dual Sewage Pumping Station works

See illustration below.¹

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 floats on the pumps are activated and, as the floats are factory set at the same level, both pumps start and pump the liquid out of the chamber until the pump floats drop and the pumps turn off.

The level of the liquid will again rise and the above sequence is repeated. As both pumps are activated each time this ensures equal wear to both pumps.

If both pumps fail to pump, the liquid level will rise to activate the high level float and the high level alarm light will be illuminated.
