Alfa Laval ALSP 60
Alfa Laval Alfa Laval ALSP 60 is identified in the source list as a screw pump. It is normally installed in an engine-room fuel, lubricating-oil or other viscous-liquid system close to the tanks and treatment equipment it serves. Its purpose is to provide smooth positive-displacement flow where liquid viscosity or suction conditions make a centrifugal pump less suitable. The source record provides a stated power of 2.2 kW, and the stated medium fuel oil/lube oil. 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 and source-listed power or medium distinguish this pump from neighboring sizes and services; refer to the manufacturer documentation for the exact flow, pressure and viscosity limits.

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 heating arrangements for viscous fluids where fitted. Inspect for external leakage and confirm the handled fluid is suitable for the installed pump. During overhaul, inspect screws, liners and bearings for scoring or contact. Refer to the manufacturer documentation for exact clearances, relief settings and wear limits.
