Vertical hollow shaft pump motor in line with IEC energy efficiency classes

Our IEC standard VHS motors are in line with IEC energy efficiency classes, a standard mainly suitable for markets in Europe, Asia, and Africa. The primary differences between IEC and NEMA standards lie in energy efficiency grades, installation dimensions, bearing lubrication methods, and wiring methods for the junction box.

Our IEC standard VHS motors can extract groundwater from depths of 100 to 200 meters, primarily used for irrigation in desert areas, airport firefighting, and agricultural irrigation in water-scarce regions.

Key Features
  • Equipped with two angular contact ball thrust bearings at the motor’s top, these motors effortlessly manage upward or downward thrust. The lower radial ball bearing handles any radial loads from the pump.
  • Designed to power deep-well turbine pumps, our vertical hollow shaft motors support self-releasing, bolted, or non-reverse couplings, as specified by the client. Located at the motor’s top, these couplings allow easy pump impeller adjustments. Access them by removing the top cover and fan housing.
FAQ

We use high-quality bearings from trustworthy brands, including TMB, NSK, SKF, and FAG, to ensure long-term durability. Bearings are essential for optimal VHS motor performance, as they withstand axial thrust, improve reliability, and extend service life. Additionally, custom bearing options are available upon request.

Yes, we have exported high-powered VHS motors worldwide, including the United States, Mexico, the Middle East, and Europe.

Yes, our motors are engineered for ambient temperatures of 50–60°C, and thanks to enhanced thermal design and high-temperature-resistant materials, our IEC standard VHS motors can operate safely at up to 70°C in harsh climates such as deserts or high-heat industrial zones.

We provide motors in IE3, IE4, and IE5 energy efficiency classes to meet varying international standards and application needs, from basic industrial usage to advanced energy-saving projects.

SEMC motors are designed with wide voltage adaptability, covering multiple regional standards including 230V, 380V, 400V, 415V (European), and 460V (North American), making them ideal for use across the globe.

Our motors are built to accommodate a wide range of input voltage, ranging from 300 to 460V.
