Engineered to deliver exceptional torque characteristics, strict efficiency compliance, and operational reliability in hazardous and demanding environments.
Shaanxi Nanfang Motor Technology Co., Ltd. stands as the authoritative global distributor of WOLONG Electric Drive Group Co., Ltd. (founded in 1984, listed on the Shanghai Stock Exchange in 2002 under ticker SH600580). Over nearly four decades of persistent engineering growth, WOLONG has established a monolithic global footprint comprising 3 major manufacturing hubs, 39 state-of-the-art factories, and 3 global Research & Development facilities.
WOLONG's commitment to industrial motor innovation is driven by a global brand integration strategy. By systematically incorporating prestigious, century-old legacy brands into its technological matrix, WOLONG has solidified its position as a global leader in high-performance electric drive systems for water, slurry, chemical process, and cryogenic industrial pumps.
The shifting economic, regulatory, and technical environment shaping high-capacity pumping systems worldwide.
With electric motor systems accounting for over 70% of industrial electricity consumption, international standards (IEC 60034-30-1) are increasingly mandating transitions to IE3, IE4, and Ultra-Premium Efficiency IE5. Our range features advanced permanent magnet (PM) synchronous motors and variable frequency drives designed to optimize pump efficiency under fluctuating load profiles.
Modern industrial operations require continuous uptime. Modern pump motors integrate vibration, thermal, and magnetic field sensors directly into the frame. Our digitalized motor systems feed diagnostic parameters to SCADA platforms, predicting bearing wear, winding insulation failure, and structural cavitation before operational failure occurs.
In oil & gas processing, refinery fluid circulation, and deep underground coal mining operations, the presence of volatile gases and dust requires certified flameproof structures. The integration of Nanyang Explosion-Proof Group (CNE) into the WOLONG architecture guarantees ATEX and IECEx compliance for critical explosion-proof pump setups.
WOLONG's strategic acquisitions integrate premier global drive technologies to provide versatile, high-end motor designs for heavy industrial systems.
By bringing together global manufacturing assets, Shaanxi Nanfang Motor and WOLONG supply customized electric motors that combine localized regulatory compliance with high-performance manufacturing pipelines:
Acquired in 2011, ATB is one of Europe's top three motor manufacturers. The acquisition integrated Morley (specializing in underground coal mining drive systems with a 130-year lineage) and Laurence Scott (renowned for custom low-starting-current nuclear-grade motors and naval defense power supplies).
A pioneer in efficiency optimization, Brook Crompton has over a century of history in high-efficiency AC motors. Under WOLONG, Brook Crompton leads design refinements for low-voltage, medium-voltage, and harsh-duty pump motors, including the iconic Brook Crompton "W" series and variable-speed systems.
Founded in Germany in 1882, Schorch motors are widely recognized in petrochemical, oil, gas, and power generation industries. Schorch provides specialized engineering for heavy-duty drive systems, water transmission pumps, variable-speed process circuits, and sub-sea drives.
In 2018, GE's commercial and industrial motor business joined the WOLONG family. This transaction integrated NEMA standard engineering and heavy-industry application experience (including water treatment, paper mills, metallurgy, and mining systems) into WOLONG's global product catalog.

Our rotors feature robust squirrel cage configurations. Cast aluminum rotors are produced using centrifugal or high-pressure die-casting to eliminate internal porosity. For high-output applications, copper bar rotors are used, with induction-brazed end rings and retaining rings designed for dynamic stability in high-speed centrifugal pumps.
Stator coils are constructed from polyester-film-wrapped wire, reinforced with high-mica tape. The entire assembly undergoes Vacuum Pressure Impregnation (VPI) to eliminate air voids. This ensures excellent dielectric strength, high thermal conductivity, and resistance to environmental moisture and chemical vapors.
Optimized using digital multi-physics and finite element simulation platforms, the high-strength cast iron or structural steel frames offer excellent rigidity and heat dissipation. They are designed to withstand high mechanical shocks, limit vibration propagation, and extend bearing life.
Equipped with an integrated air guide cylinder, silencer plates, and acoustic damping materials, our IP22 to IP55 fan covers reduce aerodynamic noise. The side-entry air inlets prevent obstruction, ensuring stable cooling and minimal noise emissions during continuous load cycles.
As industrial supply chains face changing geopolitical and economic conditions, WOLONG's advanced manufacturing infrastructure in China provides key operational advantages. The transition to Industry 4.0 smart manufacturing plants integrates automated machinery with digital quality assurance systems.
Key pillars of this production framework include:
Engineered solutions for challenging environments in global industries.
Volatile compounds and aggressive chemicals require strict flameproof construction. Our ATEX/IECEx certified motors drive high-pressure hydrocarbons, reflux, and transfer pumps in refineries. Designed with explosion-proof junction boxes and non-sparking materials (e.g., YWKK and YWKS series) to ensure safety and prevent ignition.
Underground dewatering pumps operate under continuous hydrostatic loads in wet, dusty, and methane-heavy environments. The Morley-designed flameproof AC motors and WOLONG YBSD conveyor and slurry pump drives provide robust performance for deep shaft water management systems.
Large municipal grids rely on large-capacity intake and wastewater pumps. WOLONG’s high-efficiency three-phase asynchronous motors (such as the YE3 and WE series) run continuously, helping lower public utilities' operating costs through reduced energy draw.
Every motor is tested and certified to comply with regional electrical and safety codes, enabling seamless integration into international projects.
