More about this product
The Flygt NP 3171 HT 18.5 kW (3-phase) is a submersible pump for permanent wet (P-type) installation. This Standard 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 standard-efficiency motor drives the unit. This is the ATEX explosion-protected version for wet wells classified as potentially explosive atmospheres.
