Pump, fan and compressor systems make up a large share of a plant's energy consumption and mostly draw continuous power between 60 and 100 kW. Because the load character of these three applications differs, motor selection differs too. DRG Motor supplies cast iron housed motors suited to continuous duty in this band.

Motor Selection in Pump Applications

Centrifugal pumps draw a load torque that rises rapidly with speed, so they are mostly matched with 4-pole 1500 rpm or 2-pole 3000 rpm motors. On continuously running pumps, a higher efficiency class directly lowers energy consumption.

Load Character in Fan Applications

Fans have a load torque that rises with the square of speed and run at constant speed for long periods. For this reason efficiency and continuous-duty endurance are decisive in fan drives; Class F insulation and a cast iron housing maintain a stable temperature over long operation.

Requirements of Compressor Applications

Compressors demand high starting torque and a fluctuating load. Here a strong breakdown-torque margin and a solid mechanical structure matter; the cast iron housing damps the vibration produced by the cyclic load and protects bearing life.

The Right Motor for 60–100 kW

In this power band there is no single recipe for pump, fan and compressor; pole count and efficiency class change with the load character. DRG Motor supplies from 0.55 to 355 kW; we can plan the right motor for your 60–100 kW system, with pole count and housing type, from our İzmir-based plant.
