The MK series of mechanical speed variators is available in 7 sizes. It includes foot mounted, flange mounted, pump adapters, and can integrate with any IEC motor or gearbox and can operate at zero speed. 

MK Series

The MK series mechanical variators  provide trouble-free, mechanical speed for a wide variety of applications when AC inverters are not an option. No complicated electrical wiring, no wash-down problems, and no complex manual to study. Increasing or decreasing speed requires just turning a knob.

 

Standard output flanges allow easy mounting to your existing gearbox, motor, pump, or use one of SITI’s standardized gear solutions for a compact, reliable, cost-effective solution.
