Fuel Oil Transfer Pump · Pumps
Multi-stage centrifugal pumps are essential components in marine applications, particularly for handling heavy fuels. The Heishin Pump (Sulzer) NMC Multi-Stage pump is designed to efficiently manage high-viscosity fluids such as HFO/MDO. With a capacity range of 5 to 200 m³/h, the NMC series includes models NMC 50, NMC 65, NMC 80, NMC 100, and NMC 125, catering to various flow and head requirements up to 40 to 250 meters. Originally introduced in 1985, the series comprises approximately 50 variants, all driven electrically and constructed from multi-stage cast iron. Common maintenance issues include stage wear, mechanical seal leakage, bearing wear, and cavitation. Spare parts are available from Heishin/Sulzer Japan, ensuring reliable service intervals for continued operation.
