Couplings

Franklin Electric offers this line of motor-pump couplings for maximum customer convenience in matching the Franklin motor to a variety of pump shafts. Couplings are designed to transmit the pump thrust to the motor in order to provide maximum benefits from the Franklin internal thrust bearing construction.

Hardened stainless steel spacer discs in the 4” and 6” couplings assure positive bearing between motor and pump shafts, and assure full support for downward thrust created by the pump.

8” couplings DO NOT contain hardened spacer discs, since the motor shaft itself is hardened.

All couplings include Allen head 300 series stainless steel set screws.
