Coupling selection for a CDWdrives coupling is quick and simple. Follow the guide below to find the proper coupling for your application, or contact us to have a CDWdrives engineer perform the selection.
Data required for Coupling Selection:
Driver: Water Turbine (100 HP at 1800 rpm)
Driven Equipment: Screw Compressor
Turbine Bore: 2.38″
Compressor Bore: 2.00″
Distance Between Shaft Ends: 5″
Service Factor for the Water Turbine & Screw Compressor: SF=2
HP/100 rpm = (100 HP x 100 x 2) / 1800
HP/100 rpm = 11.1
Coupling selection based on max rating: A4B
Coupling Bore Capacity: 2-7/8″
Maximum Speed for A4B is 3275 rpm unbalanced
DBSE for A4B is 5″
A4B is acceptable in this application.
