Frequently Asked Questions

• 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
• 462 – Impeller code
• MT – Motor / pressure class designation

What applications is this pump suitable for?

This model is intended for pumping wastewater containing solids and fibrous material, as well as clean water and surface water. It is commonly used in municipal sewage, industrial effluent and drainage duties where reliable operation is required and where ragging or build-up can cause blockages for conventional impellers.

What does adaptive mean?

Adaptive refers to the hydraulic’s ability to adjust internal clearances when bulky debris passes through the pump. In practical terms, the impeller can move slightly along the shaft under load, temporarily increasing clearance to help rags and fibrous material pass, before returning 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 wastewater 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 selection, 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/flange accessories, allowing connection to hose elbows, pipework, or a guide-rail claw for fixed installations. Accessories such as hose elbows, adaptor flanges and guide claws 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.
