Where the WPA 040 Is Installed in Australia
Smallest cast-iron model in the WPA range. Designed for light-duty textile machinery bobbin winders, small ventilation damper actuators, laboratory agitators, and miniature conveyor drives where the structural rigidity of cast iron is required but the loads are modest. In Australia, commonly specified by equipment builders in the textile and light manufacturing sectors of western Melbourne.
When to Choose This Model
The WPA 040 covers the below 0.48 kW. For higher power or larger shaft diameters, step to WPA 050. 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.
