Screw Pump · Pumps
Crew members and marine engineers aboard vessels depend on reliable fuel oil and lube oil pumps to ensure efficient engine operation. IMO AB's ACE model, a three-screw pump driven electrically, is specifically designed for engine-room oil service in marine environments. Common failures include rotor scoring from contaminants like cat fines or dirt, seal leakage, internal wear causing pressure loss, and relief valve leaks leading to low discharge pressure. Critical spare parts include mechanical seals, gaskets, relief valve kits, bearings, and screw sets. Regular maintenance involves monitoring suction vacuum, discharge pressure, and pump noise while ensuring clean filters/strainers are maintained. Overhauls should be performed if pressure cannot be sustained or if abnormal noises occur.
