Mouvex SLS1, SLS2 and SLS3 Hygienic Eccentric Disc Pumps
Spare Parts for Mouvex SLS1, SLS2 and SLS3 Hygienic Eccentric Disc Pumps
Product Summary
Genuine OEM spare parts for Mouvex SLS1, SLS2 and SLS3 hygienic eccentric disc pumps for food, dairy, cosmetic and pharmaceutical duties with CIP and SIP cleaning. The three sizes share almost every part, so seal sets, the size-specific piston and cylinder, transmissions and main parts are listed on one page by their Mouvex reference.

How we confirm the exact part: Mouvex spares are ordered by their reference number against the pump build shown on the nameplate (model, serial number and options code). References on this page are as printed in the current Mouvex parts list. Send the nameplate details or a photo, and tell us the liquid pumped, and we’ll confirm the right genuine parts before we quote.
Service Intervals & When to Replace
- Bellows: a leak at the vent signals bellows failure; keep the vent open to atmosphere, as a closed vent shortens bellows life.
- Piston and cylinder: wear parts; replace them as a pair when output drops or they reach the IOM minimum dimensions.
- Transmission oil: with Mouvex CS05 oil, drain every 24,000 h at or below 80°C, 12,000 h at 80–100°C and 6,000 h at 100–110°C.
- Cleaning: keep CIP/SIP inlet pressure within the IOM limit (3 barg) so the piston lifts and the cleaning flow passes through the pump.
Models
This page covers the Mouvex SLS1, SLS2 and SLS3. The model, serial number and build options code are on the pump nameplate; Mouvex matches spares to that build.
Models & Key Specifications
| Model | Max differential | Displacement | Max speed | Parts list |
|---|---|---|---|---|
| SLS1 | 16 bar | 0.017 L | 1000 rpm | PL 1004-F01 |
| SLS2 | 10 bar | 0.034 L | 1000 rpm | PL 1004-F01 |
| SLS3 | 6 bar | 0.051 L | 1000 rpm | PL 1004-F01 |
Limits from Mouvex IOM NT 1004-F00: pumped product −15°C to +110°C, CIP/SIP up to +121°C, jacket up to 5 barg. Rows marked with a size apply to that size only.
Troubleshooting
No flow or low flow
Likely cause: Port plugs left in, wrong rotation or speed too low; a bypass set below the discharge pressure or not closing; or internal wear. Action: Check the drive, rotation and speed, then measure discharge pressure. If it is low, reset or clean the bypass; if the pump is worn, replace the piston and cylinder (as a matched pair).
High vacuum at the inlet, pump noisy
Likely cause: Suction lift or suction losses too high, a blocked inlet (valve, strainer, blank seal) or product vapour pressure too high for the temperature. Action: Lower the pump or shorten and enlarge the suction line, clear the strainer and valves, and cool the product or bring the pump closer to the tank.
Low vacuum and poor priming
Likely cause: Air leaking in at the front cover seals or flanges, the bypass not seating, or internal wear. Action: Isolate the pump from the suction line and re-measure the vacuum. Replace the seal set, clean the bypass seat, or replace the piston and cylinder (as a matched pair) if the pump itself will not pull vacuum.
Bearings running hot
Likely cause: Pipework pulling on the pump flanges, poor pump-to-drive alignment, a twisted baseplate or excessive belt or chain tension. Action: Support the pipework so it does not load the pump, re-check coupling alignment at each installation stage, and make sure the baseplate sits on its mounting points.
Motor overloads or trips
Likely cause: Viscosity, specific gravity or head losses higher than the pump was selected for, speed too high, misalignment or a motor wiring fault. Action: Check the actual discharge pressure against the duty, reduce speed or heat the product, and check alignment and motor connections. Do not use the bypass as a flow control.

Mouvex SLS1, SLS2 and SLS3 spare parts: frequently asked questions
Tap a question to see the answer.
What spare parts are listed for the Mouvex SLS1, SLS2 and SLS3?
The page lists maintenance kits and seal sets first, then wear parts, then the main parts, each with the Mouvex reference printed in PL 1004-F01. Material versions such as FKM, FEP-FKM or CVT seals have their own references.
How do I order the right Mouvex parts?
Mouvex matches spares to the pump build. Tick the parts you need, choose your model in the quote form, and add a nameplate photo showing the model, serial number and options code, plus the liquid pumped. We confirm the exact genuine parts before quoting.
Are SLS1, SLS2 and SLS3 parts interchangeable?
Almost. The three sizes share the seal sets, transmissions and most main parts, but each has its own cylinder and piston set, and they are rated at 16, 10 and 6 bar respectively. Check the size on the nameplate before ordering the piston and cylinder.
Do you supply parts for other Mouvex pumps?
Yes. We list parts for Mouvex A, C, Micro C, SLC, SLS and FLO eccentric disc pumps and P Series sliding vane pumps. See our Mouvex eccentric disc pumps or all Mouvex spare parts by series. Not sure which model you have? Send a nameplate photo.
