Where the WPA 135 Is Installed in Australia
Large-scale mining conveyor drives, heavy industrial mixer systems for chemical and mineral processing, sugar mill auxiliary equipment in Queensland, and large water treatment process drives. The WPA 135 accepts motors up to 11.25 kW and is a standard specification in Australian mining tender documents for conveyor auxiliary and transfer point drives.
When to Choose This Model
The WPA 135 covers the below 11.25 kW. Step to WPA 147 for higher torque margin. 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.
