DESCRIPTION

Flygt 3356 Pump Repair Kit — Mechanical Seals & O-Ring Set

A direct-fit aftermarket repair kit for the Flygt 3356 submersible pump, replacing the primary sealing components serviced in a routine rebuild. One seal pair — 90mm upper, 80mm lower — covers the C 3356, N 3356 and L 3356 alike. The O-ring set is where these pumps differ: the column pump takes a different set from the C and N versions, so pick your version from the dropdown. Built to OEM-equivalent standards or higher.

Choose Your Kit

The seals are the same on every 3356. The O-ring set is not — the column pump takes a different set. Read the version letter off your dataplate and pick the matching row.

The Flygt 3356 is one of the large submersibles: 45 to 140 kW at 50 Hz and 70 to 280 hp at 60 Hz, on a 350mm / 14 in. discharge, six-pole at 990 r/min or eight-pole at 745 r/min on 50 Hz and 1190 / 895 r/min on 60 Hz. It is built three ways on the same seal pair — the N 3356 with the self-cleaning three-blade N-impeller, the C 3356 with the channel impeller, and the L 3356 column pump. On a pump this size the lower seal takes the grit while the upper takes the heat and the run hours, so both are replaced together.

Nameplates read C 3356, N 3356 or L 3356 with an installation prefix — NP, NS, NT or NZ on the N-pump, CP, CS, CT or CZ on the C-pump — and a drive unit designation such as 35-29-6AA, 35-35-6AA, 35-45-6AA, 43-30-6BC, 43-44-6BC, 43-56-6BC, 35-29-8AA, 35-35-8AA, 35-45-8AA or 43-30-8AA. Curve codes run 53-670 and 53-870 at 50 Hz, 63-670 and 63-870 at 60 Hz.

The O-ring set on the 3356 depends on two things: whether you have the C/N version or the L column pump, and which drive unit is fitted. So enter your full model number and the drive unit number under Pump Model Notes at checkout and we pack the kit to that pump. Easiest way: text a photo of the dataplate to 561-414-1046 and we will read both off it for you, no purchase required.

Rebuilding a 3300 or a 3306 instead? All three run the same 90mm and 80mm seal pair, but each takes a different O-ring set — order the Flygt 3306 pump repair kit or the Flygt 3300 pump repair kit for those.
