1-2 Major Application

The MVF2000 series is applied for speed control of square torque loads such as fans,
pumps, and compressors, as well as for mills, crushers, and conveyor belts that require
constant torque operation over the entire speed range. Accurate speed and torque controls
result in better energy saving, improved process quality, and prolonged equipment lifetime.
Various industry segments that require reliable and stable operation can benefit from
MVF2000's high performance:

Power Generation: coal mills, blower fans, and water pumps.

Metallurgy: conveyor belts, positive displacement pumps, fans, and water pumps.

Mining: crushers, conveyor belts, PD pumps, fans and water pumps.

Petrochemical: compressors, PD pumps, centrifugal pumps, fans and water pumps.

Cement & Materials: crushers, mixers, extruders, rotary kilns, drying furnaces, fans and
water pumps.

Sugar & Ethanol: mills, pumps, and fans.

Municipal works: water supply pumps, sewage pumps, heat network pumps.
