Submersible Pump Spline Coupling Specialists

We machine submersible pump spline coupling assemblies for leading borewell, dewatering and irrigation pump brands. Our in-house tool room allows us to deliver involute/straight splines with zero backlash, balanced torque transmission and corrosion resistance suited for harsh groundwater conditions.

Every coupling is produced in Rajkot with ISO 9001 quality systems, PPAP documentation and 100% inspection of spline profile, pitch diameter and runout. For OEMs, we offer co-engineering support to redesign couplings for higher torque, vibration reduction or NEMA compliance.

Design Support

Reverse engineering, CAD validation and tolerance stack-up for legacy pump models.

Manufacturing Capacity

Monthly output of 18,000+ couplings with CNC turning, grinding and broaching lines.

Documentation

Full PPAP, IS/NEMA certs, material traceability and ultrasonic/MPI reports on request.
