Marine-rated, per manufacturer datasheetCapacity
Fuel oil/lube oilMedium

Marine engineers and operators rely on reliable equipment like the Leistritz L2NG to ensure the efficient transfer and boosting of fuel oil and lube oil on board ships. This marine-rated pump is designed to meet the rigorous demands of the maritime industry, featuring a twin-screw pump mechanism driven by an electric motor. Its installation options include oil transfer and booster service, making it versatile for various applications. Common issues that may arise include screw and liner scoring due to contaminants, mechanical seal leakage, timing gear wear or backlash, and bearing wear from misalignment. Critical spare parts such as seal kits, bearings, timing gear components, gaskets, and screw sets are essential for maintenance. Regular monitoring of suction pressure, vibration, and seal leakage is recommended to ensure optimal performance. Additionally, checking the timing gear condition during overhauls and maintaining filter cleanliness are crucial for extending the pump's operational lifespan.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
