• Internal Pump Cleaning
– If you have thoroughly cleaned the filter cage screens
and still have diminished flow rates, then you will need to
remove the pump from the circular base to inspect and
clean the impeller rotor assembly.
– Pull the cage release tabs outward to unlock the upper
pump cage (Ex. 11).
– With the cage tabs released the filter cage can be lifted
to expose the pump (Ex. 12).
– The procedure to remove the pump from its mount
varies depending on the pump model. The 600 and
1300 are easily removed by depressing the tab on the
mounting bracket and sliding the pump forward towards
the water chamber cover (Ex. 13).
– For the 2000 model, remove the two screws securing
the pump holding brackets to allow the pump to be
lifted from the circular base. Please make a note of the
pump bracket orientation prior to removing the screws
so the brackets can be replaced onto the pump in the
same orientation. The power cord can be left in the
strain relief, if desired, in order to simplify reassembly
(Ex. 14).
– While holding the pump securely, rotate the water
chamber cover counter-clockwise so it can be removed
from the pump (Ex. 15).

– With the impeller assembly now exposed, it can be
removed from the pump by pulling outward on the
impeller blades.
IMPORTANT: Do not lose the outer rubber
impeller shaft centering bushing (Ex. 16). This
bushing sits inside the water chamber cover
and sometimes it remains in the cover when the cover is
removed (Ex. 17). If, however, this bushing stays on the
impeller shaft, simply slide it off the shaft and set it aside
or replace it in the water chamber cover so the impeller
assembly can be removed from the shaft.

– If your rotor assembly impeller and internal pump body
have excessive scale build-up, clean with a mild acid,
such as white vinegar or Aquascape Pump Cleaner
Maintenance Solution (#91143) and a kitchen sponge or
soft bristled brush that won't scratch the stainless steel.
This will remove the scale build-up and allow the pump
impeller to spin like new again (Ex. 18).

• Replacing The Impeller/Rotor Assembly and Water
Chamber Cover
– 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 pump performance, it is most likely
time to replace the impeller. Replacing the impeller is
extremely easy. Replacement impeller kits are available
through your Aquascape dealer.
NOTE: 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
(Ex. 19).
