Flygt 3140 Pump Repair Kit — Fits 3140.090 and 3140.180

Flygt 3140 Pump Repair Kit — Mechanical Seals & O-Ring Set

Direct-fit aftermarket repair kit for the Flygt 3140 submersible pump. It replaces the primary sealing components serviced during routine maintenance and rebuilds, restoring leak-free operation and cutting downtime. Both 3140 builds — the .090 and the .180 — 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 (Flygt reference 640 63 30, Type M Active)

• Lower mechanical seal: TC/TC/VIT — Tungsten Carbide / Tungsten Carbide / Viton (Flygt reference 384 00 09, Type S)

• Complete O-ring set: Buna-N (Nitrile / NBR) — Flygt O-ring kit reference 80 32 49

Applications

• Flygt 3140 — 3140.090, 3140.180

The Flygt C 3140 is a mid-size submersible C-pump built around the Flygt Nevaclog impeller, whose open channel design lets stringy solids pass instead of collecting on the vane. It handles municipal and industrial wastewater, sewage, lift-station duty, drainage and raw water transfer. Motor ratings run roughly 8.8 to 9 kW (P2), with 100 mm, 150 mm and 250 mm discharge options. A D 3140 drainage version is also in service and uses the same sealing components.

Both builds are covered by Flygt basic repair kit 601 89 31, which uses the same seals, O-ring kit and wear protector supplied here.

Prefixes and codes on the nameplate: CP (semi-permanent wet well on twin guide bars), CS (free-standing transportable with pipe or hose connections), CT (vertically mounted permanent, flanged) and CZ (horizontally mounted permanent, flanged). Head classes are LT (low head), MT (medium head) and HT (high head), followed by an impeller curve code — commonly 452 or 454 on 100 mm discharge, 432, 434 or 436 on 150 mm, and 610, 612 or 614 on 250 mm.

Add your full model number at checkout under “Pump Model Notes”. Not sure of your build? Send a photo of the nameplate to info@sealhouseusa.com, or call or text 561-414-1046 — no purchase required, our seal specialists will match it.

Also fits the Flygt 3152: the seals in this kit are the same seals used in our Flygt 3152 Pump Repair Kit. The O-ring set is what differs between the two, so order by your pump model rather than by seal.
