HYDRABATHS® PUMP 610000CD-RS
Offered in its original form with a 48-frame motor.
Only found here. 
Same specs as the original.
Motor comes with a 1-year no-fault warranty.
The R in the part number stands for a 3' cord
The S stands for air switch.
The air switch is no longer built inside the motor making it difficult to replace. 
The air switch is now in an easy-to-replace control box that the pump plugs into.
Our advanced air switch technology is second to none.
