Screw Pump · Pumps
Regular maintenance is essential to ensure reliable operation and longevity of your marine oil service equipment, particularly when dealing with fuel oil or lube oil. Leistritz’s L3MF three-screw pump is designed for such demanding applications, featuring an electric drive and robust construction suitable for marine environments. Common issues that can arise include wear on the screw set due to dirty oil, mechanical seal leakage, bearing wear from cavitation or low viscosity, and relief valve malfunctions. To mitigate these potential failures, it is recommended to regularly check the discharge pressure and suction strainer. During scheduled overhauls or when performance drops, inspecting the screws and bearings is crucial. For effective maintenance, spare parts such as mechanical seals, bearings, gaskets, valve parts, and screw sets should be readily available. By adhering to these service notes and keeping essential components on hand, you can significantly extend the operational life of your L3MF pump and maintain optimal performance in marine oil service applications.
