Four-inch motors are available in 230V single-phase (0.37 to 2.2 kW) and 400V three-phase versions (0.37 to 7.5 kW). Six-inch motors are 400V three-phase from 5.5 to 37 kW. The Omega 6" water-cooled motors use stainless steel shells and shafts, NEMA flange and spline dimensions and a thrust bearing rated 15 500 N (3 to 15 kW) or 30 000 N (18.5 to 37 kW).
Control boxes range from a simple capacitor starter for single-phase motors, through boxes with built-in motor protection, to intelligent controllers with dry-run, over/under voltage and phase protection, and mining control cabinets up to 110 kW.
Matching motor, pump and control box
- Power - the motor kW must equal or exceed the kW stated for the pump end.
- Coupling - 4" pump ends fit 4" NEMA motors; 6" pump ends fit 6" motors (some 6XNS models are supplied with a 4" motor bracket).
- Supply - 230V single-phase motors need a control box with the start/run capacitor; 400V three-phase motors need a starter with overload and phase protection.
- Protection - in boreholes that can run dry, use an intelligent control box with sensor-free dry-run protection.

Frequently asked questions
Can I use an Omega motor with a Leo pump end?
Yes. Both follow NEMA dimensions, so a 4" Omega or Leo motor fits any 4SR/4SA pump end of the right kW.
Which control box protects against dry running?
The intelligent control boxes (M8, M921, M931, M531, K531) include sensor-free dry-run protection. The standard control box only starts the motor.
What is a mining control cabinet?
A wall-mounted PLC control cabinet for a single pump up to 110 kW with flow-switch control, alarms, fault logging and full electrical protection.
