Ebara

Ebara pumps Europe produces stainless steel and cast iron pumps for the domestic, utility and industrial markets around the world. The modern, efficient design and manufacturing technology allows them to produce competitive products whilst being energy efficient.

Functioning principle
As established by the UNI EN 12845 Standard, if the firefighting unit supply pumps intervene, they are started by a pair of pressure switches via an electric control panel supplied with each pump and they must function continuously until stopping, which only occurs with manual control. The start-up of the supply pumps can cause simultaneous activation of an acoustic and luminous long-distance indicator.

The small flow rate jockey pump (pilot), intervenes in the case of small system leaks and is started and stopped automatically by its own electric control panel and relative pressure switch calibrated at a pressure value slightly higher than the pressure switch value of the supply pump. Stopping takes place when system pressure is reset.

The acoustic – luminous indicator also signals a missing phase, the voltage, lack of water, and any incorrect position of the shut-off valves both in discharge and suction. The electric control panels are equipped with pump running signals.
