Full Description

The Flygt NP 3171 MT 22.0 kW (3-phase) is a submersible pump for permanent wet (P-type) installation. This Hard-Iron 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 impeller and insert ring are cast in abrasion-resistant Hard-Iron™ for gritty, sand-laden media that would wear standard cast iron. A standard-efficiency motor drives the unit. This is the standard, non-Ex version for general duty.

Standard or Ex — which is this?

What does Hard-Iron™ add?

Abrasion-resistant high-chrome impeller and insert ring for sandy, gritty media — markedly longer wear life than grey cast iron on abrasive duties.

Is leak detection included?

Yes — FLS leakage sensing is fitted as standard on this frame. MINI CAS monitoring relays are available as an option.

Configuration shown reflects the manufacturer build for this duty point. Standard cable length as listed; longer cable to order.
