Inspection

Inspector Detail

Common issues

  • Packing/gland leakage at the plunger
  • Suction/discharge valve wear reducing volumetric efficiency and flow
  • Plunger or liner wear/scoring increasing leakage past the packing
  • Crosshead/crankcase bearing wear
  • Pulsation/vibration from worn valves stressing downstream pipework
  • Packing overheating from insufficient lubrication or cooling
  • Relief valve set-pressure drift over time

Inspection checklist

  • Check packing gland leakage rate against the baseline/normal drip rate
  • Trend discharge pressure and flow to detect volumetric efficiency loss
  • Monitor vibration at the crosshead/crankcase
  • Sample and analyse crankcase lubricant per PMS
  • On teardown, inspect suction/discharge valve seats and springs for wear
  • Inspect plunger/liner surface condition for scoring or wear
  • Verify relief valve set pressure against the nameplate
  • Check foundation bolts and alignment

Service intervals

Packing inspection/adjustmentevery 500-1,000 running hours or on leakage trend, per maker's PMS - confirm exact figure with the maker's manual
Crankcase oil changeper maker's manual, commonly every 2,000-4,000 hours or per oil analysis results
Valve overhaul (suction/discharge)condition-based, commonly in the range of several thousand hours - confirm against the maker's manual for this specific stroke/plunger configuration
Relief valve set-pressure checkannually

Typical wear limits

Plunger/liner clearancebauartüblich in the range of a few tenths of a millimetre depending on plunger diameter - confirm the exact figure against the maker's manual for the stroke/plunger size actually fitted (140-178 mm stroke, 15.85-146.05 mm plunger range per the type series)
Packing gland leakagea slow drip is typically normal/acceptable; a continuous stream indicates packing renewal is due - confirm against the maker's guidance rather than a fixed number

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

  • Plunger packing sets sized for the plunger diameter in service
  • Suction and discharge valve assemblies (seats, discs/balls, springs)
  • Plunger/liner sets matching the fitted stroke and diameter
  • Crosshead/crankcase bearings
  • Gaskets and seals for the specific configuration fitted

Safety

  • High-pressure fluid injection injury risk at the packing/plunger area
  • Relief valve discharge hazard - ensure discharge is piped to a safe location
  • Reciprocating machinery crush/entanglement hazard at the crosshead
  • Process fluid hazard depends on the specific service this pump is on (flammable/toxic fluids need their own precautions)

Class survey

Whether this pump falls under a Continuous Machinery Survey item depends on the system it serves (e.g. cargo, fire main, process injection) - confirm the applicable survey scope for this pump's specific application on board before assuming a fixed survey regime.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
