Four kit options cover the EDWARDS GXS range from GXS450 to GXS4200F — and three of them do not cover what most buyers assume they cover.

✅ Assembly kit: 8 lip seals, 8 sealed bearings, 8 spacer rings, plus O-rings, split rings and plug caps
✅ Section kit: 4 of each, one end only
✅ Lower-section fits GXS450 / GXS750F · Upper-section fits GXS4200F
✅ No GXS2600 section kit — that frame is unit-kit only

A GXS dry screw pump is built in sections — and it wears in sections too.

EDWARDS GXS overhaul kits, supplied by section:
✅ Lower-section kit — GXS160 / GXS250, 0.8 kg
✅ Upper-section kit — GXS1750F / GXS2600F, 1.2 kg
✅ Complete unit kits — GXS250 + GXS2600F, GXS160 + GXS1750F

Each section kit carries 4 lip seals, 4 sealed bearings, 4 spacer rings, plus the O-ring set, retaining rings and end caps. A complete kit is two matched section kits.

The pairing is the detail buyers get wrong: it is not by size order. A GXS160 and a GXS2600F do not share one complete kit — that site needs both section kits.

G1099-80039: the exhaust oil mist filter that belongs on every Pfeiffer DUO 2.5 and DUO 3 GC-MS backing pump.

✅ 3/8 BSP male thread, cone face + O-ring — threads straight onto the DUO exhaust port, no adapter, no PTFE tape
✅ 95% capture at 0.3 μm — glass-fibre and synthetic-fibre coalescing layer stops the sub-micron aerosol that coats benches and walls
✅ Integrated 1/4" oil return — condensed oil drains back to the pump instead of leaving with the exhaust
✅ 88.7 mm × Ø50.8 mm, ≈45 g — one-piece, tool-free swap on the 12-month service

Interchangeable with G3870-80056 for New DUO 2.5 RVP: one part covers DUO 2.5, DUO 3 and the 5973/5975/5977 GC-MSD systems on them.

Exhaust Silencer PN 04.12.6921C — for EDWARDS GXS 160/250 and GXS 450/750 Dry Screw Pumps

✅ Ø240 mm stainless chamber, 530 mm overall, 13.9 kg complete ✅ KF40 bore for GXS 160/250, KF50 bore for GXS 450/750 ✅ 90° side inlet, bolted end plate, threaded drain boss with ball valve ✅ No consumable element — routine service is the drain valve and the clamp joint

One chamber, two bores, four frames. Order by the pump spigot, not by the label: both versions carry the same part number on the tag.

ULVAC GLD201B / GLD-N201 overhaul kit ULGLD201MAK — the five part groups that fail together, in one box.

✅ 4 high-density graphite vanes
✅ 4 FKM shaft oil seals
✅ Multi-size FKM O-ring set
✅ Coupling spider + exhaust valve plates, springs and seat grommets

Graphite vanes shorten and vacuum drifts down; FKM seals harden and the pump starts leaving oil. They wear on the same hours, so they get replaced in the same teardown — not in two.

Published interval: 2000–3000 hours on clean duty, shorter on solvent, dust or corrosive gas.

BARDEN VCMP Bearings for EDWARDS GXS Dry Screw Pumps — VCMP209ASP · VCMP114 · VCMP212

✅ VCMP209ASP for the GXS160 and GXS250
✅ VCMP114 for the GXS450 and GXS750
✅ VCMP212 — the general GXS size
✅ Precision ceramic ball bearings, supplied individually by part number

Bearings set rotor position, timing clearance and shaft alignment on a dry screw pump, so their condition is the machine's performance. Confirm the pump frame from the nameplate and the marking on the bearing being removed before you order.

EDWARDS GXS Dry Screw Pump Wear Parts — for the GXS160 GXS250 GXS450 GXS750

✅ Shaft seal / lip seal 53 × 66 × 12, part number 536612
✅ Bearing sets split by pump size — GXS160 GXS250, and GXS450 GXS750
✅ Oil slinger disc and GXS series oil filter element serve the whole range
✅ Replacement wear parts supplied to fit the GXS series

Four part families cover a GXS service, and three of them fit every model in the range. Only the bearings split by pump size — and that is the one line where the wrong pick is expensive. The two sets look alike and are not interchangeable.

Exhaust Oil Mist Filter PN 004391 — for the PVR EU160 Oil-Sealed Rotary Vane Pump

✅ Ø72 × 300 mm micro body — fits the bench, cabinet and analyser frames an EU160 lives in
✅ ≥99% oil mist separation, ≤5 µm particle cut-off
✅ Holds exhaust back pressure inside a ≤1.2 bar ceiling
✅ 1500 hours or 3 months on dirty duty, up to 3000 hours on clean lab duty

The EU160 takes this one part number and nothing else. PN 004391 is a dedicated micro cartridge, not a trimmed-down version of a larger PVR filter — so the housing and exhaust port stay standard, and the element cannot be cleaned and reused.

Cooling Water Pipe Sets for EDWARDS GXS Dry Screw Pumps — GXS450 and GXS250/GXS2600

✅ Two matched groups: GXS450 at approx. 1 kg, GXS250/GXS2600 at approx. 0.8 kg
✅ Supplied as complete replacement pipe sets, not single pipe sections
✅ Wear-resistant, heat-resistant pipe for water circuit rebuilds
✅ Model-specific — GXS450 and GXS250/GXS2600 pipes do not interchange

Most cooling faults on a water-cooled dry screw pump start as a tired pipe, a fretted joint or scale inside the circuit, and they surface as a process problem long before anyone inspects the cooling side. Replacing the whole matched set in one visit costs far less than a second shutdown.

Control-side service kit for EDWARDS GXS dry screw vacuum pumps

✅ Control handle with display, keypad and 5-pin connector ✅ Handle mounting bracket, 8 × 8.5 × 9 cm ✅ Nitrogen pressure sensor with cable ✅ Dashboard operator panel with emergency stop, plus XLR connector plug

GXS pumps rarely stop because of the screws — they stop on the control side. Holding these on the shelf shortens the stoppage. Covers GXS160 through GXS2600:
