Engineered for extreme reliability, maximum energy efficiency, and certified safety in hazardous operational environments.
Shaanxi Nanfang Motor Technology Co., Ltd serves as the premier authorized global distributor for Wolong Electric Drive Group Co., Ltd. Founded in 1984 and listed on the Shanghai Stock Exchange in 2002 (code: SH600580), Wolong has transitioned from a localized motor shop into a titan of the global drive control market.
Currently running 3 major global manufacturing hubs, 39 specialized production factories, and 3 advanced research institutes, Wolong commands unparalleled engineering strength in design, fabrication, and performance testing for complex industrial applications.
Providing world-class pump motor solutions that satisfy severe technical mandates across multiple industries.
Fully compliant with international anti-explosion safety requirements, optimized specifically for chemical process pumps and oil transport operations globally.
Offering advanced IE3, IE4, and next-generation IE5 permanent magnet synchronous motors (PMSM) configured to reduce operating expenses in continuous-run pump applications.
Covering diverse voltages (LV, MV, HV) and torque configurations, suitable for handling harsh industrial media, slurry extraction, and high-pressure injection.
An authoritative analysis of engineering trends, localized challenges, supply-chain resilience, and global procurement criteria.
Modern industrial pump motor systems consume approximately 25% of the world's total industrial electricity. From municipal wastewater infrastructure to deep-sea petroleum extraction, the demand for pump drives has shifted decisively away from "commodity electric motors" toward highly engineered, application-specific fluid drive packages. Commercial duty pump motors operate under continuous thermal and electrical stresses, requiring specialized seal designs, variable frequency adaptability, and corrosion-resistant insulation technologies.
Historically, the market has been dominated by localized standards (NEMA in North America, IEC in Europe). However, as multinational corporations seek to build standard, repeatable skid architectures, manufacturers must provide globalized platforms. This requires dual-certified (IECEx/ATEX and Class I Div 2) electric motors capable of functioning globally, minimizing warehousing overhead, and simplifying field replacement programs.
The centralization of the motor manufacturing supply chain in China has created an unmatched competitive advantage in product scale, cost control, and rapid adaptation. China-based manufacturing hubs integrate advanced vertical processing—including raw material sourcing, automated electrical steel stamping, computerized copper coil winding, high-pressure die-casting, and VPI vacuum impregnation—all within tightly knit industrial zones.
Furthermore, domestic factories leverage advanced automated testing protocols, enabling 100% testing of critical performance benchmarks (such as starting torque curves, insulation resistance under simulated humidity, and vibration parameters) before delivery. This drastically shortens the OEM product design-to-production lifecycle, enabling customized shaft extensions, custom mounting brackets, and specific cooling profiles to be engineered and delivered in half the time of Western competitors.
Wolong's rise to a global manufacturing force was accelerated by strategic acquisitions of historic European and American brands, which brought over a century of motor engineering heritage:
Leveraging state-of-the-art physics simulation, premium materials, and certified engineering systems.
R&D centers in China, Europe, and Japan collaborate with the Shanghai Central Research Institute to pioneer next-generation permanent magnet (PM) motors and variable frequency drive (VFD) controls.
Possessing globally respected brands (ATB, Schorch, Brook Crompton, Laurence Scott, Morley) that ensure technical acceptance in oil and gas, heavy mining, and utility infrastructures.
Specialized encapsulation, flameproof enclosures, and increased-safety designs certified under ATEX, IECEx, and regional hazardous regulations.
Over 30 years of global technological consolidation and industrial asset growth.
Accumulated with abundant assets and decades of motor manufacturing expertise, Wolong Electric Group sought to bridge the gap between Eastern scale and Western technical heritage. Through a series of acquisitions, Wolong has consolidated the global motor market, acquiring intellectual property, premium manufacturing footprints, and engineering teams.
In 2011, Wolong acquired 97.94% of the Austrian ATB Group, positioning the company among the top tier of European electrical drive producers. The ATB family brought high-specification expertise, particularly the Morley brand, which has provided heavy flameproof mining motors for nearly 130 years.
Simultaneously, Laurence Scott brought bespoke engineering capabilities for low starting current configurations—a requirement for nuclear cooling systems and naval generator plants. Additionally, the integration of Schorch (Germany, founded 1882) expanded Wolong’s capabilities in custom high-voltage pump motors for municipal sewage, steel processing, and heavy marine propulsion.
Every element is engineered to meet severe service conditions, ensuring durability and thermal safety.
Featuring centrifugal cast aluminum constructions that integrate the bars and end rings into a single piece. For larger high-voltage process pumps, copper-bar rotors with welded end rings and protective high-speed retaining rings prevent deformation under extreme startup inertia.
Constructed utilizing high mica content tape, wound precisely and treated with advanced Vacuum Pressure Impregnation (VPI). The VPI resin creates a void-free structure, offering high dielectric strength, resistance to moisture, and Class H thermal stability.
Designed using structural-fluid multi-physics simulations. High-strength cast iron (or fabricated steel) frames provide high structural rigidity, excellent heat dissipation, and isolate vibrations, ensuring low temperature rises under continuous load.
An integrated aerodynamics system combining air guide cylinders, protective inlet windows, and silencer plates. Compact and lightweight, the side-inlet design reduces turbulence noise while maintaining IP22 standard touch safety protection.

We adhere to a comprehensive global certification strategy to support international distribution and deployment:
Engineered to drive critical infrastructure under continuous loads globally.
As a global supplier of electric motors and drives, Wolong’s industrial solutions power critical equipment across key sectors:
Integrating specialized shaft configurations, variable frequency speed control, and customizable thermal monitoring ensures our systems adapt to local requirements. With R&D and production sites in Germany, Austria, the UK, China, and North America, we provide support and short lead times globally.
Answers to key technical questions from procurement officers and engineering leads.
Commercial duty pump motors are designed for continuous duty (S1 cycle) under variable loads. They feature higher electrical stator steel quality, optimized slot fill factors, upgraded insulation (Class F or H), and larger shaft diameters to support high mechanical shear forces. They also incorporate bearing protection like insulated bearings or shaft grounding rings to prevent electrical erosion when run with Variable Frequency Drives (VFDs).
This dual-shore manufacturing model combines European design standards, engineering specifications, and quality controls with the cost-efficiency and supply-chain speed of Wolong's production bases in China. This integration allows us to deliver high-quality, European-engineered drive solutions with optimized cost structures and shorter delivery times.
We supply motors certified to ATEX and IECEx standards for Zone 1 and Zone 2, as well as Class I Div 1 and Div 2. Common protective designs include Flameproof (Ex d), Increased Safety (Ex e), Non-Sparking (Ex nA), and Positive Pressure Shell (Ex p) configurations, ensuring compliance with local hazard safety directives.
Yes, customization is a core service. We can design and produce custom shaft extensions (single, double, keyed, or tapered), modify terminal box orientations, integrate RTD temperature sensors or space heaters, and supply custom flange dimensions to match legacy motor frames.
We supply motors meeting IE3, IE4, and IE5 efficiency standards. Upgrading to IE4 or IE5, particularly in continuous-run pump applications, can reduce electrical energy consumption by 2% to 5%. In high-horsepower installations, the energy savings can offset the initial motor purchase cost within 12 to 18 months.
Engineered for extreme performance, mining operations, and specialized high-voltage applications.
