Screw Pump · Pumps
Designed for efficient marine applications, the LPQ pump from IMO AB operates on a three-screw principle, driven electrically and installed in engine rooms for oil service. This pump excels with lube and fuel oils, ensuring smooth operation within harsh maritime environments. Common issues include mechanical seal leakage, internal wear from screws, damage due to suction strainers clogging, and bearing degradation caused by contaminated oil. Regular maintenance focuses on cleaning the suction strainer, monitoring discharge pressure, checking for seal leaks, and addressing any abnormal pump noise. Critical spares such as seal kits, bearing sets, relief valve kits, gaskets, and screw replacements are recommended for timely repairs during routine checks or when performance declines.
