L Series

Fuel oil and lube oil transfer is essential aboard any vessel, requiring reliable equipment to ensure smooth operations. Kral's L Series pumps are designed specifically for this marine environment, offering robust performance and dependable service. These pumps feature a three-screw design, driven electrically, and are intended for installation within marine oil service applications. To maintain optimal performance, regular service checks are recommended, including inspecting the suction filter, discharge pressure and temperature. Coupling alignment should be checked after any motor/pump service. Common issues that may arise with the L Series include mechanical seal leakage, internal leakage from screw wear, cavitation caused by a blocked suction filter, and bearing damage resulting from misalignment. To address these potential failures, it's advisable to stock spare parts such as mechanical seals, screws, bearings, gasket kits, and pressure valve components. Overhaul the pump if you experience abnormal noise or a decline in performance.
