the impeller assembly is the only moving part on the AquaJet ™
pump and will experience wear and tear. if you’ve cleaned
the pump, as described above, and still experience poor

Kits are available through your Aquascape ® dealer.
1a. Note the orientation of parts in this photo. the
replacement kits include all parts shown. Make sure to
remove all of the original parts from the inside of the pump
before installing the replacement impeller kit.
1b. A centering bushing is required on both ends of the
impeller shaft, one bushing is located inside the pump and
an outer bushing sits in the water Chamber Cover.
2. Slide the first interior bearing washer onto the ceramic shaft.
3. place the ceramic impeller shaft into the pump, checking to
be sure the centering bushing seats inside the pump.
4. Carefully, slide the impeller back onto the shaft. Use
caution, the impeller Assembly is magnetic and will be
forcefully pulled back into the pump.
5. install second outer bearing washer over the impeller shaft.
6. the water Chamber Cover is replaced by lowering the
cover over the impeller shaft so the impeller shaft seats in
the impeller bushing. the cover tabs should fit inside the
matching slots on the pump face
7. when the pump water Chamber Cover is rotated clock-
wise less than a ¼ turn, the pump discharge fitting on the
pump Cover is in the vertical position.
