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.
Complete Seal, Dual Bearing & Impeller Rebuild Kit for Watkins 37334 (Part# 71894) - Vendor Code 4081
This comprehensive repair kit services 1.0 HP Watkins pumps specifically designed for Wavemaster 48 motors. The impeller features precise specifications: 2 1/8" eye diameter, 1/4" vane width, and 3 7/8" outside diameter. Compatible with Vendor Code# 4081 wet ends.
Electrical Reference Guide: A properly matched 1.0 HP impeller operates at approximately 11-12.0 Amps on high speed with 115V power, or 7-8.0 Amps at 230V. Consult the amperage chart corresponding to your motor voltage to verify correct horsepower.
Important: Installing an oversized impeller will NOT increase spa performance. Incorrect sizing causes motor overheating and potential damage during high-speed operation. Always match impeller specifications to your existing setup.
Frame Size Identification: Distinguish between 48 Frame and 56 Frame wet ends by measuring motor through-bolt spacing. The 48 Frame measures 3 5/8" center-to-center (5 3/16" diagonal X-pattern) with 1/4" bolt heads. The 56 Frame measures 4 1/8" center-to-center (5 3/4" diagonal X-pattern) with 5/16" bolt heads.
Vendor Code 4081
This complete kit includes the mechanical seal assembly and two precision bearings required for full pump restoration. Individual seal-only and seal-with-bearing combinations are available separately for Watkins Vendor #4081 XP2 model wet ends if partial servicing is preferred.
