Why use our High Specification Pump Station?
How our High Specification Pump Station works
See illustration below.¹
As the level of the liquid rises in the chamber the first two level floats, the stop and duty start floats are activated and the duty pump starts and pumps the liquid out of the chamber until the stop float drops and turns the pump off. The level of the liquid will again rise and due to the autochangeover control system the other pump will start. This ensures that the two pumps do an equal amount of work.
If the liquid level reaches the height of the second level float and the pump fails to pump, the level of liquid will continue to rise until the third float is activated and calls the standby pump to start. This pump will then start and pump until the stop float drops. If both pumps fail to pump, the liquid level will rise to the fourth float and the high level alarm will be activated.
