Electric Motors

Successful Delivery of Vertical Hollow Shaft Motor

Vertical hollow shaft motors (VHS motors) are electric motors for deep well water pumps, typically installed in deep wells or boreholes to extract or transport groundwater. Our VHS motors are used in a variety of cases, including mine rescue, construction drainage, agricultural irrigation, industrial and mining enterprises, urban water supply and drainage, and wastewater treatment.

Your trusted source for electric motors and metallurgical equipment

Since our beginning in 2010 we have focused on manufacturing and sales of metallurgical equipment and we continually improve our products and service. Verified during over a decade of activity, we gradually realized the significant impact of large electric motors on the quality of metallurgical equipment. So, we expanded our factory to increase the production and sales of electric motor products.
Today, we are a company that primarily offers electric motors, such as deep well pump motors, DC motors, AC motors, high-voltage motors, and explosion-proof motors. Additionally, we also offer metallurgical equipment, such as induction furnaces, smelting furnaces, and electric arc furnaces, which are mainly used in the production and processing of metal materials, including smelting, casting, and rolling processes.
