The impeller for ESPA IRIS 1000M and NOX 100 pumps is a rotating hydraulic component dimensioned for the performance parameters of these single-phase pool pumps.
The shared design for both models means that only a single part type needs to be kept in stock to service both pump ranges.
Wear or cavitation damage to the impeller blades manifests itself as a drop in flow, increased noise and higher electricity consumption.
Replacement takes place after dismantling the front pump section and releasing the impeller from the shaft — no specialist workshop equipment is required.
The original ESPA part guarantees precise hydraulic parameters and vibration-free operation after installation.
