IMO ACG 500e16

IMO AB (Colfax) IMO ACG 500e16 is identified in the source list as a screw pump. It is normally installed in engine-room fuel, lubricating-oil or other viscous-liquid service close to the tanks and treatment equipment it serves. Its purpose is to provide smooth positive-displacement flow, particularly where liquid viscosity or suction conditions make a centrifugal pump less suitable. The existing database record states 16 bar. The screw elements and close internal clearances create the pumping action, so cleanliness, lubrication by the handled fluid and correct relief protection are important. The exact model designation identifies a particular screw-pump size and configuration; flow, differential pressure and viscosity capability must be confirmed from the manufacturer documentation.

Common failures & inspection points

●Internal screw or liner wear caused by abrasive contamination or prolonged service, resulting in reduced capacity and increased internal leakage
●Dry running or poor inlet supply caused by empty tanks, closed valves or suction restriction, resulting in abnormal noise, rapid heating or seizure risk
●Shaft-seal leakage caused by worn sealing faces or misalignment, resulting in visible oil or fuel leakage
●Bearing or timing-component deterioration caused by contamination, misalignment or lubrication problems, resulting in vibration and abnormal mechanical noise
●Relief-valve malfunction caused by deposits, incorrect setting or mechanical sticking, resulting in abnormal discharge pressure or inability to protect the pump

Service & Maintenance

Check suction strainers, inlet conditions, shaft seals, bearings, drive coupling and relief arrangements. Monitor discharge pressure, noise, vibration and delivery for signs of internal wear or suction starvation. Avoid running the pump dry and verify that heating arrangements for viscous fluids are functioning where fitted. Inspect for external leakage and confirm that the handled fluid remains within the viscosity range intended for the installed pump. During overhaul, inspect screws, liners and bearings for scoring or contact. Refer to the manufacturer documentation for the exact clearances, relief settings and wear limits.
