This replacement is configured for select whirlpool bathtubs originally equipped with the NR1-C Gemini Plus II pump, box part number 001F88C. Verify the complete number on your original pump label before ordering.
NR1-C 001F88C Gemini Plus II Whirlpool Pump Replacement
Replace a discontinued NR1-C Gemini Plus II 1/2 HP whirlpool bathtub pump with a modern 120-volt replacement solution. The original NR1-C was a cord-connected bath pump without a built-in air switch and was identified by box part number 001F88C.
The replacement pump provides dependable 8.5-amp performance while retaining the familiar Gemini-style plumbing arrangement used in many older whirlpool bathtubs. It is intended for applications where the pump is activated by a separate bathtub control system rather than an air switch built into the pump.
The original box part number is 001F88C. Do not confuse it with 0001F88C. These numbers should not be treated as interchangeable unless the original pump label and installation specifications have been verified.

The replacement motor may have a different stated horsepower or amperage than the original NR1-C. Compatibility is determined by the complete electrical, control and plumbing configuration—not horsepower alone.
Designed for Cord-Controlled Installations
The original NR1-C configuration did not contain a built-in pneumatic air switch. Its power cord connected the pump to a separate control device, relay or switched receptacle installed with the bathtub. Confirm that your existing system controls power externally before ordering.
