MOPX-210

The Alfa Laval S.p.A. MOPX-210 is a legacy high-speed disc-stack oil separator intended for centrifugal cleaning of fuel oils, lubricating oils or other compatible mineral oils according to its installed configuration. It is normally installed in a machinery-space oil-treatment system together with the necessary feed, heating, outlet and control equipment. Inside the rotating bowl, centrifugal force separates denser contaminants from the lighter oil phase, with the disc stack increasing the effective separation area. Depending on bowl arrangement and system setup, the separator may be used for purification, clarification or another manufacturer-approved oil-cleaning duty. The MOPX family was used in marine fuel- and lubricating-oil separation systems; the exact bowl, discharge and control arrangement depends on the installed specification. The numeric designation in MOPX-210 identifies the model within its family, but the provided source does not give capacity or construction details for this exact variant. Exact configuration, operating values, wear limits and application suitability must therefore be taken from the manufacturer documentation and machine nameplate.

Common failures & inspection points

Incorrect bowl or process configuration for the intended duty, producing poor separation, unstable outlets or product loss
Accumulated sludge or deposits in the bowl and disc stack, producing reduced capacity, declining separation efficiency or vibration
Worn spindle, bearings or drive components, producing abnormal noise, vibration or unstable running
Damaged seals, blocked passages or leaking connections, producing external leakage or internal cross-flow
Faults in operating-water, control or sludge-discharge functions where fitted, producing incomplete cycles, alarms or failed separation

Service & Maintenance

Confirm the exact separator specification and intended duty before dismantling or changing bowl components. Inspect the bowl, disc stack, spindle, bearings, drive train, seals and all process passages for deposits, corrosion, erosion and wear. Where automatic operating-water or sludge-discharge functions are fitted, test their sequence and valve condition after service. Monitor vibration, noise and cleaned-oil quality after reassembly. All exact service intervals, tolerances, tightening values and process settings must be taken from the relevant manufacturer documentation.

Replacement Parts

Carry the manufacturer-recommended service kit for the exact serial number and separator specification. Depending on the design, additional critical spares may include bearings, seals, drive components, bowl-service parts and operating-water or control-valve components. Do not rely on apparent similarity between separator families when selecting parts.
