Eheim Locking Device for Pump Cover – Professional 2226 / 2228 and Professional 3 2080 / 2180 (7342358)

The Eheim Locking Device for Pump Cover (7342358) is a genuine OEM replacement locking ring designed to secure the pump cover on the Eheim Professional, Professional II, and Professional 3 1200XL external canister filter ranges. This locking ring clips over the pump cover assembly, holding it firmly in position against the filter canister body — ensuring a secure, stable connection and preventing the pump cover from loosening during filter operation.

Over time locking rings can crack, lose tension, or break — particularly after repeated removal and refitting during routine filter maintenance. Prompt replacement ensures smooth operation and protects against pump cover instability that can lead to leaks or loss of suction. Replacing with a genuine Eheim OEM part ensures an exact fit and restores full locking function. Aquaristikshop
