Sewage pump 380V 1.5kW Hmax 22m Qmax 417l/min LEO 3.0 50WQ8-20-1.5F (7738133)

Submersible sewage electric pumps for sewage disposal. They combine high efficiency in the most adverse conditions. Dual-channel impeller provides high resistance to clogging, high hydraulic efficiency at high flow rates, stable operation without turbulent turbulence.
Single-phase electric pumps are equipped with an automatic float switch.
Pumps of this series are easy to install and maintain. Both mounting on an automatic quick coupling is possible, as well as free installation for mobile operation of the pump.
The combination of a compact design with the ability to supply high pressure makes these pumps an ideal solution for wells, both with temporary and permanent installation.
