Centrifugal Pump · Pumps
This is a marine-rated centrifugal pump designed for demanding oil service applications. IMO AB manufactures the ACF model, built for fuel oil, lube oil, and hydraulic oil transfer. The ACF pump utilizes a three-screw pump design, driven electrically and ideally installed within an engine-room oil service system. To ensure reliable operation, regular maintenance is crucial. This includes cleaning suction strainers frequently, verifying the relief valve's operation and checking for seal leakage. During scheduled overhauls or when flow or pressure drops, inspect the screw set and bearings for wear. Common issues with the ACF include screw set scoring caused by contaminated oil, mechanical seal leakage, relief valve sticking due to sludge or varnish, and bearing wear resulting from using low viscosity oil. For critical fuel and lube duties, it's recommended to stock essential spare parts such as the mechanical seal, bearing kit, gasket set, relief valve parts, and a complete screw set.
