Description

It is about 7 1/4"" across the face of the pump, it measures about 7 3/8" from the bottom to the top of the pressure side of the volute, it also measures 15" from the back to front edge. The Suction and Pressure side thread fittings are called 2" x 2" but measure 3" from the edge of the thread to the edge of the thread.
Note: There are other companies offering other brands that are not exact fit for your tub.. This pump is an exact fit..
NOTE: This Pump looks a lot like an Aqua-Flo and a CMP Pump and they will interchange if you replace the entire pump!
NOTE about Watkins Wavemaster Complete Pumps: Watkins Does Not Make Pumps. They buy different brands of pumps and put their numbers on them.. If you want the original Watkins numbers on your new pump we don't offer that.. What We offer is the exact pump or the closest equivalent to the original pump if it is obsolete that they would buy and put their numbers on from the original pump manufacturers. The main difference between one you would buy from them now and ours is the exhaust vent in the back will not come on our pump.. We think it is a bad idea as it does not allow the motor to cool as it was intended to cool and does not have any redeeming quality for you as an end user.. See the below picture for what will NOT come on our pump.. If you must have that feature Watkins is the only source..
Note: If your original Pump has this on the back with a hose attached none of my pumps will have that nor will they be able to accept this part from your old pump.. You will save 100's of dollars over the original pump with that attachment that is only used to put heat from the motor under the tub and I believe the motors stay cooler without that device and last longer..
