Screw Pump · Pumps
Crew members, engineers, and operators on board marine vessels depend heavily on reliable fuel oil and lube oil supply systems to ensure efficient operations. Allweiler’s SNF model, a three-screw pump driven electrically, is specifically designed for marine oil service applications. Common issues include mechanical seal leakage, screw wear due to contaminated fuel, bearing damage from misalignment, and relief valve leakage affecting discharge pressure. To maintain optimal performance, it's crucial to keep suction strainers clean and manage oil viscosity and temperature correctly. After servicing, always check coupling alignment to ensure proper operation. Regular overhauls are recommended if there is a drop in capacity or pressure.
