Fuel Oil Transfer Pump · Pumps
Internal gear pumps belong to a category of marine equipment designed for handling viscous fluids. The SPX FLOW TopGear GM/H Internal Gear pump series is part of this category and includes models such as the TopGear GM 25, GM 50, GM 80, GM 120, TopGear H 80, H 120, and H 200. These pumps are capable of handling a flow range from 2 to 180 m³/h and are suitable for heavy fuel oil (HFO), marine diesel oil (MDO), and other heavy viscous oils. Constructed with options for heated jackets and multiple material choices, these pumps operate electrically and have been in service since the early 1990s. Users should ensure operation within viscosity and temperature limits to avoid common failures such as bushing wear under high-viscosity service, seal leakage at elevated temperatures, gear scoring from particles, and relief valve contamination. A global service network supports these pumps, ensuring reliable maintenance and spare parts availability.
