WHPX Series
The WHPX series was Alfa Laval's marine standard separator in the 1960s and 1970s. Manual sludge discharge (no automatic discharge) made operation labour-intensive. Occasionally still found on very old vessels (built before 1985), but practically no longer maintainable with original parts. Historically interesting as precursor to the MAPX series, which introduced automatic discharge.

Common failures & inspection points
Paring disc, top disc, mud ports check for dull spots/wash-out; erosion depth >0.2 mm (bowl/cap) or >0.5 mm (other) = replacement.
Leaks at cover/bolted joints/mud outlet; gasket rings (EPDM) change every 6000–8000 h, original parts only.
Check vibration/noise; bearings change in pairs every 12000–16000 h, lubricate correctly; do not increase throughput during vibration.
Belts every 3000 h (tension per manufacturer), cracks/wear; coupling check for axial play (>0.5 mm = fault), corrosion.
Monitor current consumption nominal/actual; clean bowl during shutdown; check pre-filtration + lubrication; limit sludge volume.
