VHS Motors

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.

Applications
Agricultural irrigation and rural water supply
  • High-altitude and mountainous water extraction: Long-shaft deep-well pump motors navigate rugged terrains like plateaus and mountains, accessing groundwater from wells up to 100 meters deep to support irrigation and drinking water needs in drought-prone areas.
  • Large-scale farmland irrigation: With high-flow and high-head performance, these motors efficiently draw groundwater to meet the demands of water-intensive crops like wheat and rice.
Urban and industrial water supply
  • Urban residential water: Deep-well pump motors deliver consistent drinking water for cities, using smart automated controls to optimize flow for high-density needs while minimizing energy consumption.
  • Industrial process and cooling water: Supporting industries like petroleum, chemical, and pharmaceutical, these pumps extract groundwater or liquid raw materials; stainless steel models withstand corrosion and high temperatures in harsh industrial settings.
Applications
Pulp and Paper Mills
  • Continuous high-load operation: VHS motors provide reliable, round-the-clock performance for pulp agitators, pumps, and vacuum systems commonly found in paper manufacturing lines.
  • Moisture-resistant design: Constructed with sealed enclosures and anti-corrosive materials, our VHS motors, such as NEMA standard VHS, TEFC VHS, etc., are well-suited for humid, fiber-laden environments typical of pulp processing plants.
Municipalities and wastewater treatment systems
  • Minimal energy consumption: Our VHS motors available in IE3, IE4, and IE5 efficiency classes minimize energy consumption, which helps municipalities reduce power expense while maintaining long-duration operation.
  • Anti-reverse protection: Equipped with a steel ball type anti-reverse mechanism, our VHS motors ensure unidirectional operation, preventing costly pump damage caused by flow reversal.
Well Drilling Operations
  • High thrust capacity: Our VFD compatible deep well pump motor supports both standard and high thrust configurations, ideal for deep-well water extraction in operations reaching hundreds of meters underground.
  • Flexible adaptability: Our VFD-compatible VHS motors comply with IEC or NEMA standards, enabling easy installation worldwide, with customizable IP55 or IP67 protection, supporting various environments.
Mining and drilling operations in a harsh environment
  • Designed with Totally Enclosed Fan Cooled (TEFC) motors: Prevents dust and moisture from entering and damaging the insulation system. Our TEFC VHS motors operate reliably even in high-temperature or humid environments.
  • High durability: Built with an explosion-proof motor engineered for hazardous situations, and equipped with high-output torque to deliver powerful, consistent torque. Our VHS motors drive conveyors, pulverizers, crushers, etc., with exceptional efficiency.
Features
  • Our VHS motors have no special requirements for well pipes or water pipes, making them suitable for steel pipe wells, ash pipe wells, and earthen wells. Under permissible pressure, steel pipes, rubber pipes, and plastic pipes can all be used as water pipes.
  • Our VHS motors are easy to install, use, and maintain, require minimal space, and do not need a pump house.
  • Our VHS motors are easy to repair and have a long service life.
