Description
Complete Service Kit for Watkins 2 HP Pump Models 1019801-03, 0977601-03, 39577-03 - Vendor Code 3536
This comprehensive repair package contains everything needed to restore your Watkins 2 HP circulation pump: impeller assembly, mechanical seal, bearing, silicone lubricant, and seal installation tool. Designed specifically for Vendor Code 3536 pumps used in Hot Spring, Caldera, Tiger River, and Hot Spot spa systems.
Critical Impeller Measurements: The impeller measures approximately 4 1/8 inches across the face (edge to edge), 3 inches from front tip to back sleeve tip, and 7/16 inch from inside vane edge to edge. Some impellers display casting number B351-21 - if yours has this marking, you must verify the edge-to-edge measurement as the manufacturer trims one casting to different horsepower specifications.
The included bearing is engineered to match the motor specifications for this wet end configuration.
IMPORTANT COMPATIBILITY NOTE: This wet end resembles Aqua-Flo wet ends but components are NOT interchangeable between brands. Verify your pump manufacturer before ordering.
Pump union O-rings for 2 5/8 inch center-to-center 2 inch unions available separately for Watkins HotSpring Caldera Tiger River Hot Spot applications.
