Alfa Laval MAPX / MOPX Separator Spares — Gasket Kits, Disc Stacks, Gravity Discs and Friction Pads

Service parts for Alfa Laval MAPX and MOPX marine separators: bowl gasket kits, disc stacks, gravity disc sets, friction pads and spindle assemblies — what each does, which sizes the catalogue lists, and the data a purifier-spares quotation needs.

The purifier wear groups

MAPX (fuel) and MOPX (lube-oil) separators from Alfa Laval dominate mid-size engine rooms. Their service life revolves around five groups, all represented in the catalogue:

The two numbers that matter

• Separator type and size from the nameplate (e.g. MAPX 207 S-24, MOPX 207 SGT-24) — the suffix matters for kit content.
• Serial number — gasket kit revisions follow the machine series.
• For gravity discs: the fuel density/viscosity the plant separates, or the bore of the disc currently fitted.
• Service level: intermediate (gaskets, pads) vs major (bearings, spindle) — kits are quoted accordingly.

Adjacent systems are covered in the fuel-oil viscosity guide and the bilge-water MEPC guide.

Purifier spares are quoted against nameplate type and serial — with those two numbers, kit revision questions disappear and the quotation lands within a day.

Frequently asked questions

Where can I buy Alfa Laval MAPX or MOPX spares?

Gasket kits, disc stacks, gravity disc sets, friction pads and spindle assemblies for MAPX/MOPX separators are listed on cballast.com — request a quotation with the nameplate type and serial; dispatch is worldwide.

What does a separator gasket kit contain?

The sealing rings the bowl and frame need at an intermediate service — bowl seal, sliding-bowl-bottom rings and the associated O-rings per the machine's kit revision.

How is a gravity disc selected?

By the density of the oil being separated: the disc bore positions the oil/water interface, and the set covers the range a MAPX 207/209 needs; state the fuel density with the enquiry.

When do friction pads need renewal?

When the bowl takes visibly longer to reach speed or the coupling squeals at start — pads are a fast, cheap preventive renewal.

Are disc stacks supplied new or reconditioned?

Both routes are quoted where available (the MAPX 309 stack, for example, is listed as a reconditioned-exchange item); condition is stated on the quotation.
