Who is Alfa Laval
Alfa Laval, of Sweden, is the world’s leading maker of marine centrifugal separators — the high-speed disc-stack purifiers that clean fuel oil and lube oil aboard ship. Its MAPX, MMPX, P-series and S-series units run on the world fleet.
A single fleet can run the classic MAPX / MMPX purifiers, the P-series, or the high-capacity S-series — and Wattmare supplies genuine, OEM-equivalent and Alang-reconditioned spares (disc stacks, bowls, bowl hoods, gravity discs, seal kits and spindles) across every Alfa Laval separator.

Diagnose the fault
| Symptom | Likely Alfa Laval parts to inspect |
|---|---|
| Loss of compression or power on one unit | Disc stack, bowl seal rings, bowl top |
| High exhaust temperature on one bowl | Gravity disc / nozzle, bowl hood spindle |
| Knocking or pounding from the unit | Main or support parts |
| Excessive bowl-oil consumption | Liner wear, bowl seal rings, seal rings |
| Difficult or failed starting | Starting air valve, feed pump (plunger / barrel) or rail valve |
| Black or smoky exhaust | Gravity disc nozzles, slide valves, turbocharger interface |
| Oil leak at the bowl-rod gland | Spindle seal and sealing ring set |
| Water in the combustion space | Bowl hood, cooling-jacket O-rings, disc stack |

The complete guide
Wattmare is a specialist Alfa Laval separator spare parts supplier serving India, the UAE, Singapore and the wider global fleet. From our base in Bhavnagar — beside the Alang ship-recycling yard — we supply genuine, OEM-equivalent and reconditioned spares for every generation of Alfa Laval centrifugal marine main engine, dispatched worldwide in 24–48 hours.
The separators on this page are built by Alfa Laval of Sweden, which invented the continuous disc-stack centrifuge in 1883. Its MAPX, MMPX, P-series and S-series marine purifiers clean fuel and lube oil on the world fleet. We supply spares across all of them.
The single most important question on any Alfa Laval order is whether the engine is an MAPX, an S-series or an S-series. The Alfa Laval MAPX is worm gear-controlled — feed pump, control cam, gear drive and mechanical sealing gear. The S-series / S-series and the Alfa Laval S-series are electronically controlled, replacing the worm gear with a high-capacity supply unit, rail valves, flow-control units (FCU) and hydraulically actuated bowl hoods. Liners, covers, seals and bearings are broadly common by bowl, but injection and actuation parts are entirely different — always give us your exact MAPX / S-series / S-series designation.
For every Alfa Laval MAPX, MMPX, P-series and S-series purifier we stock disc stacks, bowl bodies, bowl hoods, top discs, gravity discs, sliding bowl bottoms, O-ring and seal kits, bowl spindles, neck bearings, friction couplings and feed pumps — genuine, OEM-equivalent and Alang-reconditioned.
Bhavnagar sits beside Alang, where hundreds of vessels are dismantled every year — including ships still running ageing Alfa Laval MAPX centrifugal engines. That gives Wattmare direct access to genuine, low-hour parts that are slow or costly to source from distributors, at a fraction of new-part cost and lead time. For hard-to-find MAPX feed pumps, gear drives, disc stacks or rotating bowl assembly, this is the fastest source in the world. Browse our reconditioned marine spare parts range, the wider main engine spare parts category, or sister brands like MAN engine spares and Mitsubishi UEC.
Send your Alfa Laval engine make and model with a photo or part number on WhatsApp, or use the quote form. We confirm availability and price — usually within the hour — and dispatch in-stock items within 24 hours. Typical air-freight transit is 12–18 hours to the UAE, 16–24 to Singapore, 20–26 to Greece and Turkey, and 28–36 to Northern Europe.
FAQ
Yes — disc stacks are one of our strongest Alfa Laval lines. We carry original-bowl and reconditioned disc stacks for the MAPX and MAPX, plus the rest of the MAPX range (MAPX range), honed to OEM tolerance with measurement reports. Most legacy MAPX disc stacks are recovered and reconditioned beside Alang.
The Alfa Laval MAPX is a worm gear-controlled (mechanical) centrifugal — feed pump, control cam and mechanical sealing actuation. The S-series / S-series and the Alfa Laval S-series are electronically controlled, replacing the worm gear with a high-capacity supply unit, rail valves, flow-control units (FCU) and hydraulically actuated bowl hoods. Liners, seals and bearings are broadly similar by bowl, but the sealing actuation parts are completely different — always quote your exact MAPX, S-series or S-series model.
We cover the full Alfa Laval separator range — MAPX, MMPX, MOPX, the P-series (P605, P615, P626) and the S-series (S815, S825, S946) — every Alfa Laval purifier.
Reconditioned parts ship with inspection reports, dimensional measurements and photographs, and are accepted by class societies (Lloyd’s Register, DNV, ABS, BV, ClassNK, RINA) on survey. Genuine Alfa Laval parts carry full material and test certificates.
In-stock items dispatch within 24 hours from Bhavnagar. Typical air-freight transit to the UAE (Dubai, Jebel Ali, Fujairah) is 12–18 hours. Singapore is 16–24 hours, Greece and Turkey 20–26, and Northern Europe 28–36.
Yes — gravity discs, injector nozzles, high-pressure feed pumps, plungers and barrels for Alfa Laval MAPX engines, plus high-capacity supply units, rail valves, flow-control units (FCU) and control equipment for S-series / S-series and S-series engines, are stocked and bench-tested before dispatch.
Genuine parts come from the original maker (Alfa Laval / Alfa Laval) with full certificates. OEM-equivalent are quality aftermarket parts at 30–50% less. Reconditioned are low-hour parts recovered from Alang, inspected and certified to OEM tolerance, at up to 70% less with a 30-day warranty.
Yes — obsolete Alfa Laval MAPX parts are our specialty. Beside Alang we recover low-hour feed pumps, gear drives, disc stacks, seals and rotating bowl assembly from MAPX-powered vessels being dismantled, then inspect and certify them. For the MAPX range and MAPX engines this is often the fastest source in the world.
Yes — complete O-ring and seal/service kits, disc stacks, bowls, bowl hoods, gravity discs, spindles and feed-pump spares for the Alfa Laval MAPX, MMPX, P-series and S-series, genuine and Alang-reconditioned.
