7″ submersible electronic multi-impeller pump designed for use in water wells, tanks or cisterns. The pump is suitable for use in residential building service for pressurization, rainwater reuse and gardening and irrigation. It integrates the electronics for automatic switching on and off, a double mechanical seal in an oil chamber, a non-return valve and a handle for transport. Electronic operation also protects against the dry run. Built with a innovative modular design: the hydraulic part, the motor, the electrical part and the filter can be disassembled separately, simplifying the maintenance activity.
