The impeller for the ESPA Niper 400 and NOX 25 pumps is a shared hydraulic rotating part with performance parameters corresponding to the 400 W / NOX 25 class.
The precisely shaped blades ensure a flow characteristic suitable for circulating water in smaller pools and for use as a supplementary circulation pump.
Wear or cracking of the blades causes a drop in flow rate and an increase in the current draw of the pump motor.
Replacement with an original part is an economical solution before buying a new pump – the whole job usually takes less than an hour.
The original ESPA design guarantees precise dimensional tolerances and balance for smooth, vibration-free running of both models.
