Description: This after-market impeller is used on the after-market 2.0 HP Wavemaster 8000/8200 jet pumps. This impeller screws onto the pump motor’s threaded shaft with regular right-hand threads.
Installation: The steps to replace an impeller are very similar to replacing a wet-end kit and take about the same amount of time.
Step 1. Unscrew and Remove the volute cover of the Wet End.
Step 2. Use a pair of plyers to hold the motor shaft while you turn the impeller counterclockwise.
Step 3. Turn the impeller counterclockwise until it is free from the motor shaft.
Step 4. If the spring-loaded part of the shaft seal, or the wear ring are still on the impeller, remove them.
Step 5. To install the new impeller, simply reverse steps 1 – 4.
Please check the vendor code or pump model on your pump before ordering replacement parts and use the chart to determine the correct impeller replacement. If your vendor code reads “3536”, there is no replacement impeller and the 77712 complete wet-end replacement is needed. If your vendor code is “3861”, please call 805-541-9000 or text us photos of your pump’s labels.
|This impeller will work on the following wet-end kits:|
|Wet End||Impeller||Shaft Seal||Wear Ring|
*Wet-end label: 91041820-000; Stamped on wet end leg: 92770705; Stamped on volute cover: 91231605. If the label/sticker reads 91041820-000, use 71405-SB. If your wet end has been changed in the past and there is a label/sticker that reads 91041610-020-001, use 71405.
**71405-SB Dots: silver, blue(use 71409-E wear ring)
If you can’t determine the dots on your impeller, buy the entire wet-end kit. The installation time is about the same.
