Description: This is the 1.0 HP impeller for the Wavemaster® 4000 jet pump.
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 is still on the impeller, remove them.
Step 5. To install the new impeller, simply reverse steps 1 – 4.
Important information for replacement parts:
Please check the vendor code or pump model on your pump before ordering replacement parts and use the chart to determine the correct wet-end replacement. If your vendor code reads “3536“, use IMP-77709. If the vendor code is “3861” or has a “-01, or –02” at the end of the model number, please call 805-541-9000 or text us photos of your pump’s labels or stickers.
