WEG W22 355L 160kW 6-Pole IE3 Motor

The WEG W22 355L 160kW 6-Pole IE3 motor provides 985 RPM operation ideal for direct-driven centrifugal pumps, cooling tower fans, and large industrial fans across the GCC region. The 6-pole design eliminates the mechanical complexity and maintenance burden of gearboxes in many low-to-medium speed applications, reducing the total installed cost and improving long-term reliability metrics for asset-intensive operators like Saudi Aramco, Marafiq, and SWCC.

Operating at 985 RPM, the W22 355L 6P delivers 1551 Nm of shaft torque—sufficient for direct coupling to large centrifugal pumps in the 1500–2500 m3/hr flow range commonly deployed in industrial cooling water systems, fire water systems, and process water distribution networks. The high torque output at low speed is a particular advantage for pump startup sequences where fluid inertia must be overcome smoothly to avoid water hammer events that could damage piping and valves.

For SWCC (Saline Water Conversion Corporation) desalination plants at Jubail, Yanbu, Shoaiba, and Ras Al-Khair, the W22 355L 6P represents an ideal drive motor for brine recirculation pumps and product water transfer pumps. WEG motors have accumulated millions of operating hours in desalination service globally, demonstrating resistance to the humid, salt-laden coastal atmospheres prevalent at Red Sea and Arabian Gulf coastal installations. Standard IP55 protection with additional sealing options provides adequate environmental protection, while C4 or C5-M corrosion protection coatings address the aggressive marine environment.

The motor's vibration characteristics—tested and certified to ISO 10816-3 Grade A—are particularly important for large pump systems where mechanical vibration can accelerate seal wear, misalignment, and bearing failure. Factory dynamic balancing to G2.5 quality (G1.0 optional) ensures smooth operation from first startup. In-service vibration monitoring connections are compatible with major PdM (predictive maintenance) platforms used by Saudi industrial operators.

For Ma'aden mining operations at Al-Zubara phosphate complex and Ras Al-Khair industrial city, the W22 355L 6P is specified for slurry pump drives where the combination of high torque, moderate speed, and robust construction addresses the severe duty conditions. The motor's bearing arrangement with reinforced drive-end bearing is optimized for the high radial loads inherent in direct-coupled slurry pump configurations.
