The impeller cover for the Marina / Elite Crystal-Flo CF60 and CF80 canister filters. It caps the impeller well and holds the rotor square; a cracked or warped cover lets the impeller wander, which shows up as rattling and lost flow long before the pump actually stops.
Notes
- CF60 and CF80 only — it does not fit the CF20 or CF40.
- Cover only; the impeller itself is a separate part.
- Check the O-ring seating while the cover is off — a tired seal causes the same symptoms.
Also for these filters: CF40 impeller assembly and foam pads.
