The Flygt NX 3171 SH is a 22 kW submersible pump from the 3000-series X-type range, supplied here in the ATEX Ex-rated build with the ie3 + hard-iron™ impeller & insert ring. The X-type has drilled mounting flanges and no predetermined mechanical connection, so it adapts to wet-well or dry-well installation (a cooling jacket is fitted for dry-well duty).

Full Description

Overview

This listing is the Flygt NX 3171 SH rated at 22 kW on a 3-phase supply, built with the ie3 + hard-iron™ impeller & insert ring. The N-hydraulic keeps the impeller clear of rag and solids for sustained efficiency on wastewater and effluent duties, and the Hard-Iron high-chrome impeller and insert ring add abrasion resistance for gritty media. The IE3 premium-efficiency motor lowers running cost over the pump life.

Self-cleaning N-hydraulic maintains its duty point and resists blockages in solids-laden flows.

Frequently asked questions

Is this the ATEX Ex-rated version?

Yes – this listing is the ATEX Ex build for installations classified as a potentially explosive atmosphere. A standard (non-Ex) build is also available.

Can it be used in a dry-well installation?

Yes. The X-type is designed for both wet-well and dry-well use; for dry-well duty a cooling jacket must be fitted.

Does it include leakage sensing?

Yes – NX 3153/3171/3202/3301 units include FLS leakage sensing as standard. It can be left disconnected if not required, with no change to the pump.

Which impeller / curve does this use?

Impeller 270, 272, 274 – 275. The hydraulic family (SH) and impeller code together fix the duty point; ask for a sizing check if you are unsure which curve matches your flow and head.

All units 3~ unless stated. Standard cable length as specified; longer cable to order. Image for illustration.
