Fuel Oil Transfer Pump · Pumps
Three-screw pumps are commonly found in shipboard applications where high-pressure fuel oil handling is required. These pumps are designed to efficiently handle heavy fuel oil (HFO) and marine diesel oil (MDO) with capacities ranging from 5 to 300 cubic meters per hour. The Kral L Serie features a robust cast iron construction, suitable for demanding marine environments, and is powered by electric motors. This pump series offers a variety of sizes, including L 32, L 42, L 55, L 70, L 85, and L 105, catering to different flow and head requirements, with a head range from 40 to 200 meters. Introduced in 1990, the L Serie has been a reliable choice for medium-duty applications. Common issues encountered include screw wear, seal leakage, relief valve malfunctions, and bearing wear. Spare parts are readily available under the designation "Kral L parts," and standard service procedures are provided for maintenance.
