Application

HS112M2-4 7.5hp 5.5kw 3 phase hollow shaft electric motor is a new type of motor with an internal joint designed for high-pressure pumps. It reduces the overall size of the hollow shaft and maintains all the technical and maintenance advantages of a standard motor. It adopts a new technology design, 100% copper wiring, C&U bearing, and shaft extension through high-frequency quenching treatment, significantly improving mechanical strength, low-temperature rise, fast heat dissipation, high efficiency, and energy-saving. In addition, it is connected to the pump for high-pressure water column cleaning.
