  • 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..
  • Compare your screws to be sure that this is the correct wet end.

  • When putting your cord back on the new pump note C= Common or the White Wire, L= Low Speed and is usually the Black Wire and rarely the Red Wire, H=High Speed and is usually the Red Wire but occasionally the Black, Green = Ground or the Green wire. They way you can tell if you have it wired correctly is when you power up the pump should go into Low Speed First. If it goes into High Speed you need to power down and reverse the red & black wires and power back up and verify it goes into Low Speed first. If you leave it wrong it will overheat and damage the Hot Tub especially during warm weather...

Description

Independent Supplier & Replacement Part Notice

We are an independent parts supplier and are not affiliated with, sponsored by, or endorsed by Watkins, Hot Spring, Caldera, Tiger River, or Solana. These names and their part numbers are used only to identify compatibility.

We offer replacement parts as alternatives to spa-branded parts. When this listing identifies a part as the same original-manufacturer replacement, it is supplied under the component manufacturer’s branding and part number, which may differ from the Watkins or spa-brand label and number. Other compatible alternatives are identified in the individual product listing. Please review the listed specifications, fitment details, and any installation differences before ordering.

This dual-speed 48 Frame complete spa pump delivers 1.0 Horsepower at 10.3/3.8 Amp and carries Watkins Vendor Code 3536. Manufactured by LX, this genuine replacement typically displays part number 37334-03 on Watkins-branded versions.

Physical measurements include approximately 7 1/4" face diameter, 7 3/8" height from base to volute pressure side top, and 15" depth from rear to front edge. The inlet and outlet connections are designated 2" x 2" with actual thread-to-thread measurement of 3".

Overall Dimensions: 15-3/16"L x 8-7/16"W x 8-7/16"H

IMPORTANT: This unit shares design similarities with Aqua-Flo and CMP models and can be swapped as complete assemblies. Verify you're selecting the correct frame size—this 48 frame motor back measures under 6" across, while 56 frame versions exceed 6".

Bleeder Barb Compatibility Note: If your existing wet end features a bleeder barb with flat-head screwdriver slot bleeder screws, a replacement bleeder barb will be required. Wing nut style indicates newer barb design—replacement only necessary if damaged.
