The impeller is a key component of the hydraulics of the Neptun ST800 counter-current unit – its shape and dimensions directly determine the performance and flow of the entire unit. Wear or damage of the impeller shows up as a drop in the counter-current’s performance and increased pump noise.
The replacement impeller precisely matches the original and is made of material resistant to chlorinated water, UV radiation and the chemicals used in pools. Replacement requires dismantling the hydraulic section of the counter-current pump.
We recommend having the impeller replaced at an authorised service centre or in the company of a specialist, so that the joint is sealed and the pump works with its original parameters after the repair.
