12 Vertical Hollow Shaft Motors

Supporting Energy Efficiency in Water Management

We have successfully completed the manufacturing and delivery of twelve vertical hollow-shaft electric motors, specially engineered for use in deep well pumping stations as part of a large-scale energy upgrade project.

These motors were designed and built to combine mechanical reliability with energy efficiency, supporting the transition toward more sustainable water infrastructure.

Technical Highlights

• Frame sizes: IEC 160 to IEC 280

• Protection: IP55, with insulation class F (temperature rise limited to 80°C)

• Bearings: Heavy-duty thrust bearing on top, oil-lubricated DE bearing for smooth operation

• Winding protection: PTC thermistors included, PT100 available on request

• Custom engineering: All 12 units built according to NEMA Premium Efficiency guidelines

• Mechanical upgrade: Ratchets constructed with ball mechanisms instead of pins for greater durability and operational reliability

These motors are built for vertical installation in deep well applications, combining structural robustness with continuous performance — especially where axial load and thermal stability are critical.

This project reflects not only our technical capacity, but also our ongoing commitment to providing solutions where efficiency, reliability, and engineering precision align.
