Brief introduction of utility model energy saving vertical multistage fire pump

The utility model discloses an energy-saving vertical multistage fire pump comprising a water inlet section, a middle section, a water outlet section, an impeller, a main shaft and a guide vane, wherein the impeller is arranged in the guide vane and the water outlet section through a main shaft; In the middle section, the runner of the water outlet section is in the form of a volute, and the final impeller is directly arranged in the volute. The utility model has no final guide vane in the water outlet section, the water is directly discharged into the volute channel of the water outlet section after being discharged by the final impeller, and then discharged from the water outlet. This can improve the flow of water, reduce energy loss, improve pump efficiency, more beneficial to greatly reduce the vibration and noise of the pump.
