The high-pressure water feeder system, characterised in that the pump (1) has a double-circuit suction system. One suction circuit is equipped with an electromagnetically-operated two-way valve (4) on the conduit, which connects the tip of the water hydrant (H1) to the equalising tank (2), equipped with electric breaker switches (12 and 13) of the water level signalling device. This circuit is also equipped with a non-return valve (8) mounted on the conduit, which connects the equalising tank (2) to the suction side of the pump (1). The second suction circuit is equipped with an electromagnetically-operated two-way valve (7) and with electric pressure-operated breaker switches (14 and 15) mounted on the conduit, which connects the tip of the second water hydrant (H2) to the suction side of the pump. The delivery conduit (16) of the pump (1) is connected through an electromagnetically-operated (6) two-way valve and the overflow valve (3) to the conduit connected to pump (1) at the suction side. The delivery conduit is connected through an electromagnetically-operated two-way valve (5) to the conduit, which leads to the tank (2). |
