The impeller of the 11504 pump is a key rotating part that directly determines the flow and pressure throughout the entire pool filtration circuit. Worn impeller blades cause a drop in flow, an increase in noise and higher electricity consumption.
The original part is made of durable engineering plastic, which withstands the chemicals contained in pool water throughout the pump’s entire service life. Replacing the impeller is the most economical way to restore pump performance.
Installation involves removing the pre-filter and accessing the pump shaft. When replacing the impeller, we recommend also checking the condition of the mechanical shaft seal and the O-rings sealing the hydraulic part.
