The MD 40 impeller with a single-groove shaft design is a replacement hydraulic part designed for the repair of MD 40 pumps. Wear or damage to the impeller causes a drop in flow rate, increased noise and, ultimately, the pump’s inability to perform its function.
Replacing the impeller with a new original is an economical alternative to purchasing an entire new pump, restoring the original hydraulic performance and extending the overall service life of the unit. The part is made of materials resistant to pool chemicals and cavitation wear.
Replacing the impeller requires basic knowledge of the pump construction and appropriate tools, so we recommend entrusting it to an experienced service technician. A correctly fitted impeller restores the full performance of the pump without the need for further adjustment.
