Frequently Asked Questions

What does the model number mean?

• N – Flygt Adaptive high-efficiency non-clog impeller design
• S – Portable / semi-permanent wet well arrangement. The pump is supplied with the Flygt square 4-bolt outlet, to which a hose elbow or guide-rail claw can be fitted as required (supplied separately)
• 3085 – Pump model series
• .190 – Explosion-proof (Ex) version with grey cast iron construction
• 254 – Impeller code
• SH – Motor / pressure class

What is the Adaptive N-impeller?

The Adaptive N design allows the impeller to move slightly along the shaft when bulky debris passes through the pump. This temporarily increases internal clearance, helping rags and fibrous material pass before the impeller returns to its normal position for efficient operation.

Why would I choose an Adaptive N pump?

It aims to combine the hydraulic efficiency of a channel-style impeller with clog resistance closer to that of a vortex pump. In real wastewater duties this can reduce unplanned blockages while still maintaining stronger efficiency than a pure vortex design.

What Adaptive N is not

Adaptive N does not make a pump immune to all ragging or unsuitable applications. Correct pump sizing, operating point and installation remain essential, and performance should always be verified against the manufacturer curve and actual site conditions.

How can this S version be installed?

The S configuration is intended for portable or semi-permanent wet well use. The 3085 series uses the Flygt square 4-bolt discharge outlet. Although not a factory DIN flange, this outlet is compatible with DN80 PN10 adaptor flanges, allowing connection to hose elbows, pipework, or a guide-rail claw for fixed installations. Flygt claws or compatible third-party accessories can be used to suit an existing system. All accessories are supplied separately.

Can this replace my existing Flygt pump?

In many cases, yes. If you provide your existing model number or duty point, we can confirm suitability before purchase.

Please send photos of your current discharge connection and installation arrangement and we can advise on the most practical way to connect this pump.
