Complete 1.0HP Impeller and Seal Assembly Kit for Watkins Part Numbers 37334 and 71894
This comprehensive seal and impeller kit services Watkins Vendor Code 4081 pumps designed for Wavemaster 48 1.0HP motors. The impeller features precise measurements: 2 1/8" eye diameter, 1/4" vane width, and 3 7/8" outer diameter specifications.
Electrical Performance Specifications:
- 230V operation: approximately 7-8.0 Amps at high speed
- 115V operation: approximately 11-12.0 Amps at high speed
Critical Installation Warning: Never install an oversized impeller expecting increased performance. Incorrect sizing causes motor overheating and permanent damage during high-speed operation. Always verify horsepower requirements using the amperage chart method described below before selecting your replacement kit.
Frame Identification Guide:
Determine your frame type by measuring motor through-bolt spacing:
- 48 Frame: 3 5/8" spacing (or 5 3/16" diagonal X-pattern) with 1/4" bolt heads
- 56 Frame: 4 1/8" spacing (or 5 3/4" diagonal X-pattern) with 5/16" bolt heads
Horsepower Verification: Check your motor's amperage rating at high speed. For 115V motors, expect 11-12.0 Amps with 1HP impellers; 230V motors should read approximately 8.0 Amps at high speed. Consult compatibility charts for other horsepower ratings.
Compatible Vendor Code: 4081
