DERAN Propeller Pump Gear Drives are designed to drive low speed propeller type and mixed flow pumps, typical applications are Flood control, Sewage  pumping, De-watering, and Aqua-culture.
The design of fan cooled propeller pump gear drive and sprag non-reverse are the choice of pump system designers and engineers world wide. Fan cooling eliminates corrosion, freezing and the added maintenance costs required to operate water cooled systems. The sprag non-reverse operates at all speeds, bathed in oil, eliminating the   problems associated pin type non-reverses and slow vertical shaft speeds.                                         All catalogue ratings include a minimum AGMA 1.5 Service factor. Bearing L10 life will exceed 30,000 hours in all applications. Actual bearing life calculations are available on request for your specific application.
