Fill cycle

The fluid enters the pump body by gravity, pushing the suction valve (1). The air release valve (2) is open to allow air to evacuate while the pump is filling.

In maximum position, the float drives a mechanism that simultaneously triggers the closing of the exhaust valve and the opening of the compressed air valve (3).

Empty cycle

The increase in pressure in the body of the pump causes the closing of the suction valve (1) and the expulsion from the liquid to the network via the valve retention (4).

The return of the float to the low position triggers, unlike before, the closing of the compressed air valve (3) and the opening of the air release valve (2).

From then on, a new cycle would begin.

This mechanical operation does not consume compressed air in the absence of fluid to pump.
