Operating principle

Operating principle

The tank is supplied with water from a water supply system or network through a float valve, which regulates the water level in the tank. The valve is installed in the chimney so as to use the full active capacity of the tank. Water is supplied from the tank through the suction pipeline / pipelines. In the suction chambers there are suction baskets equipped with non-return valves.
In the case of tanks supplying fire-fighting pumping stations, water is taken from the tank through suction pipelines with foot valves and anti-vortex plates. It is possible to discharge excess water to the sewage system through the installed overflow pipeline.
