More about this product
The Flygt NP 3171 MT 15.0 kW (3-phase) is a submersible pump for permanent wet (P-type) installation. This IE3 Premium build runs the patented self-cleaning N-impeller, whose back-swept leading edge and relief groove push solids through the pump rather than letting them build up. The hydraulic parts are grey cast iron — the baseline build for general duty. A premium-efficiency IE3 motor lowers running cost and energy use over the pump’s life (the kW rating differs slightly from the equivalent standard build). This is the ATEX explosion-protected version for wet wells classified as potentially explosive atmospheres.
