The Amarillo Automatic Combination Drive offers a reliable system for automatically changing from electric motor to the stand-by power source. There is no need for manually changing the clutch to transmit power with the gear drive.











The system is designed so that during motor operation only the pump headshaft and the outer drive body (726) of the automatic clutch rotates. A steady bearing is supplied to insure that the headshaft stays in alignment. The stand for the electric motor is furnished with the drive and is available in standard NEMA motor sizes as listed in Table 1.
The Automatic Combination Clutch is available on the Models 30 through 200A. Additional sizes may be available upon request. The Factory should be consulted on all applications.
