Combination Drives

A Combination Drive is known for complete reliability and for such operations that require complete reliability Combination Drives are the number one choice.

Combination gear drives give the users the leverage of operating pumping system with two alternate power sources. In case of a power failure or for example say a motor failure, the drive can be converted simply for an engine or turbine operation. Though the combination drives can come in with solid or hollow shafts, normally a hollow shaft (vertical) electric motor is mounted on top of combination gear drives. Between an electric motor and gear drive, a coupling is positioned on the pump head shaft. The function of the coupling is for disconnecting the gear drive from the system in case of electric motor operating the pump. It is on the design of the coupling that the change over system from electric to engine power is automatic or manual.

Advantages of Combination Drives
Flexibility of Operation : In combination drives, as the engine is activated to power the pump, the coupling rotates the electric motor and pump treating it as one. The electric motor carries the thrust of the pump, as the pump adjusting nut is placed at the top of electric motor. This gives the Combination gear drives the flexibility to function with or even without thrust from the pump.
Special Design : In combination gear drives the automatic or manual couplings have an unique design. This design allows maintaining the pump head shaft alignment centered under all types of operating conditions. Thus there is elimination of the problems of pump head shaft whip and vibration.
