They can be used to extract water of shaft sump, local water and water pit, and discharge the sewage with solid particles such as cuttings, coal pellets and sand. Their motors are flame-proof submersible three-phase asynchronous motors. The pumps have advantages such as small foot space, convenient installation and using, reliable and durable for explosion-proof, long service life.
