Maytronics Dolphin Ex 45 CB black impeller cover 2010 - M96310045

Maytronics Dolphin Ex 45 CB black impeller cover 2010

The impeller cover is the protective lid that sits directly over the pump impeller inside the motor unit of your Dolphin robotic pool cleaner. It shields the spinning impeller from debris ingress, maintains the correct hydraulic pressure within the pump chamber, and keeps the impeller correctly seated during operation. This is the black variant specific to the 2010-generation motor unit fitted to the Dolphin Ex 45 CB.

Function and role in the pump circuit

The impeller draws water up through the robot and drives debris into the filter cartridge or bag. The cover seals the top of the impeller bay, directing flow efficiently through the pump and preventing short-circuiting of the water path. Without an intact cover, suction performance drops immediately and debris bypasses the filter — the pool will not be cleaned effectively regardless of how long the cycle runs.

Compatible models

This black 2010-series impeller cover is designed for the Maytronics Dolphin Ex 45 CB. Maytronics uses colour-coding to differentiate impeller assemblies across its range: the black variant is dimensionally specific to its corresponding motor generation and will not interchange with yellow-variant covers from other platforms. Always confirm your motor unit generation before ordering.

Symptoms that indicate replacement is needed

Common signs of a failed or missing impeller cover include a sudden loss of suction, water bypassing the filter and returning to the pool unfiltered, unusual gurgling or cavitation noise during a cleaning cycle, and visible cracking or deformation of the cover body. If the robot moves normally but leaves debris behind, inspect the impeller cover first — it is one of the most frequently damaged wear items in this area of the machine.

Why genuine Maytronics matters

Aftermarket impeller covers are manufactured to looser tolerances and can crack under the pressure differential generated by the pump, or fail to seat flush — recreating the very problem you are trying to fix. Genuine Maytronics parts are engineered and tested to work seamlessly with Dolphin cleaning systems, preserving the hydraulic efficiency and motor longevity that the original design specifies. Fitting anything other than a genuine part on a serviceable robot risks premature motor failure.
