DST

Dayuan DST series pumps have the advantages of compact structure, small volume, beautiful appearance, small installation area, stable operation, long service life, high efficiency, low power consumption and convenient decoration. The electric pump is mainly composed of motor, mechanical seal and pump. The motor is a three-phase asynchronous motor. The rotor shaft of the electric pump adopts stainless steel butt shaft, which can effectively improve the wear resistance and corrosion resistance of the shaft. At the same time, it is also convenient for the maintenance and disassembly of the impeller.
