Product overview :
Self-cool high-lift downdraft pump adopt wet water-filled submersible motor, cavity as the water channel between motor shell and the retaining barrel can make the motor fully cool and let the submersible pump have the characteristics of good thermal condition , long life , high efficiency, simple structure and low cost.
National patent , retaining barrel , downdraft , high power, high flow, high-lift pump, downdraft pump is designed for mine underground rescue drainage as water-carrying tool, and it can completely drain the mine water and have the characteristic of rational structure , high efficiency and low energy , convenient installation and maintenance, reliable using.
