This impeller is compatible with the ESPA IRIS 650/750M, Silen I 50 12M, Niper3-650, Blaumar N2 and NOX 50 pumps, so it covers a whole group of related models with a single SKU.
The precise geometry ensures that the impeller fits into the hydraulic section of all the above-mentioned pumps and restores their nominal flow rate and pressure.
Replacement is recommended in the event of a drop in flow rate, increased noise or visible erosive degradation of the blades of the original impeller.
The part is made of durable plastic resistant to the chemicals in pool water as well as to mechanical wear during long-term operation.
