Flygt 3101 Pump Repair Kit — Fits 3101.090 and 3101.180

Flygt 3101 Pump Repair Kit — Mechanical Seals & O-Ring Set

Direct-fit aftermarket repair kit for the Flygt 3101 submersible pump. It replaces the primary sealing components serviced during routine maintenance and rebuilds, restoring leak-free operation and cutting downtime. Both 3101 builds take the same sealing set, so one kit covers the series.

What’s included

• Upper mechanical seal: TC/TC/VIT — Tungsten Carbide / Tungsten Carbide / Viton

• Lower mechanical seal: TC/TC/VIT — Tungsten Carbide / Tungsten Carbide / Viton

• Complete O-ring set: Buna-N (Nitrile / NBR)

Applications

• Flygt 3101— 3101.090 and 3101.180

The Flygt 3101 is a compact submersible channel impeller pump built for municipal and industrial wastewater, sewage and drainage duty, typically on a DN 100 discharge in three-phase 400 V service. It is the pump you find in small lift stations, pumping stations, basement and building drainage sets, and package treatment plants — the sort of installation where a single unit runs unattended for years and gets rebuilt rather than replaced. Its channel impeller passes wastewater without the clogging that catches closed impellers, and its seals wear the way every submersible’s do: grit at the lower face, heat and running hours at the upper. This Flygt 3101 repair kit replaces both, along with the full O-ring set, so a rebuild puts the pump back to leak-free service in one pass.

Both builds are covered by Flygt basic repair kit 601 89 45, which uses the same seals and O-ring set supplied here. Enter your full model number at checkout under “Pump Model Notes”.
