Where the WPA 175 Is Installed in Australia
Infrastructure-scale drives: large dam penstock actuators, heavy mining conveyor head drives, industrial kiln rotation systems, and large-scale water treatment clarifier bridge drives for 30m+ diameter tanks. The 175 mm centre distance delivers over 1,200 Nm output torque at 150 kg unit weight, serving the upper end of single-stage worm gear capacity in heavy Australian industry.
When to Choose This Model
The WPA 175 covers the below 21.50 kW. Step to WPA 200 for the heaviest loads. Choose cast iron over aluminium when the application involves sustained vibration, belt-tension side loads, outdoor installation, or ambient temperatures above 45 degrees C.
For materials, configuration variants, efficiency data, lubrication, and selection methodology, refer to the WPA/WPS Series overview.
