A century of diesel
Mitsubishi Kakoki Kaisha (MKK) is founded in Japan.
MKK develops the self-cleaning Selfjector marine oil purifier.
The Selfjector SJ-H Hercules becomes a marine fuel- and lube-oil standard.
MKK launches the high-performance SJ-G Genius Selfjector series.
Wattmare keeps every Mitsubishi Selfjector SJ-G, SJ-H and SJ-T purifier running with genuine, OEM-equivalent and Alang-reconditioned spares.
Who is Mitsubishi
Mitsubishi Kakoki (MKK), of Japan, builds the Selfjector — the self-cleaning marine centrifugal oil purifier that cleans fuel oil and lube oil aboard ship. Its SJ-G Genius, SJ-H Hercules and SJ-T Selfjector units run across the world fleet.
A single fleet can run the classic SJ Selfjectors, the SJ-H Hercules, or the high-performance SJ-G Genius — and Wattmare supplies genuine, OEM-equivalent and Alang-reconditioned spares (disc stacks, bowls, bowl hoods, gravity discs, seal kits and spindles) across every Mitsubishi Selfjector separator.

Diagnose the fault

|---|---|
| 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 separator | Main or spindle bearings |
| 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 Mitsubishi Selfjector 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 Mitsubishi centrifugal marine main engine, dispatched worldwide in 24–48 hours.
The separators on this page are built by Mitsubishi Kakoki (MKK) of Japan — the maker of the Selfjector self-cleaning marine centrifuge. Its SJ-G, SJ-H and SJ-T Selfjector purifiers clean fuel and lube oil on the world fleet. We supply spares across all of them.
The single most important question on any Mitsubishi order is whether the engine is an SJ-G, an SJ-H or an SJ-H. The Mitsubishi SJ-G is worm gear-controlled — feed pump, worm gear, gear drive and mechanical gravity disc gear. The SJ-H / SJ-H and the Mitsubishi SJ-H 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, hoods, bowls and bearings are broadly common by bowl, but injection and actuation parts are entirely different — always give us your exact SJ-G / SJ-H / SJ-H designation.
For every Mitsubishi SJ-G, SJ-H and SJ-T Selfjector 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 Mitsubishi SJ-G 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 SJ-G 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.

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 Mitsubishi lines. We carry original-bowl and reconditioned disc stacks for the SJ-G and SJ-G, plus the rest of the SJ-G range (SJ-G range), honed to OEM tolerance with measurement reports. Most legacy SJ-G disc stacks are recovered and reconditioned beside Alang.
The Mitsubishi SJ-G is a worm gear-controlled (mechanical) centrifugal — feed pump, worm gear and mechanical gravity disc actuation. The SJ-H / SJ-H and the Mitsubishi SJ-H 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, bowls and bearings are broadly similar by bowl, but the gravity disc actuation parts are completely different — always quote your exact SJ-G, SJ-H or SJ-H model.
We cover the full Mitsubishi Selfjector range — SJ-G Genius, SJ-H Hercules and SJ-T — every Mitsubishi Selfjector 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 Mitsubishi 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 Mitsubishi SJ-G engines, plus high-capacity supply units, rail valves, flow-control units (FCU) and oil-feed equipment for SJ-H / SJ-H and SJ-H engines, are stocked and bench-tested before dispatch.
Genuine parts come from the original maker (Mitsubishi / Mitsubishi) 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 Mitsubishi SJ-G parts are our specialty. Beside Alang we recover low-hour feed pumps, gear drives, disc stacks, bowls and rotating bowl assembly from SJ-G-powered vessels being dismantled, then inspect and certify them. For the SJ-G range and SJ-G 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 Mitsubishi SJ-G, SJ-H and SJ-T Selfjectors, genuine and Alang-reconditioned.
