The impeller is a key hydraulic part of the ESPA Nadorself 400T pump, and its condition directly affects the flow and pressure produced by the counter-current jet.
Manufactured from durable engineering plastic, it offers low weight, resistance to cavitation and a long service life even during continuous operation in an outdoor installation.
A worn or damaged impeller manifests itself as a drop in the power of the counter-current jet or increased pump noise – replacement with an original part eliminates these problems.
Installation is straightforward: after removing the front cover of the pump, the old part is replaced with a new one and the pump is reassembled without any special tools.
