F.0. Pump TOP-203HWFGVB-035 VOLCANO Marine Boiler Fuel Oil Pump
The F.0. Pump TOP-203HWFGVB-035 VOLCANO (Model / Part No: TOP-203HWFGVB-035) is an industrial high-temperature fuel oil trochoid gear pump unit manufactured for Volcano Co., Ltd. marine auxiliary boilers and heavy fuel oil (HFO) burner systems. Designed for positive displacement transfer and pressure feeding of preheated heavy fuel oil, light marine gas oil, and diesel, this pump ensures stable volumetric flow and constant pressure delivery to burner nozzle lances.
Built with special heat-resistant Viton mechanical seals and high-precision trochoid rotors, the pump withstands continuous high-temperature oil recirculation without pressure loss or leakage. Installed on Volcano marine boilers, shipboard sludge incinerators, and industrial combustion plants, the TOP-203HWFGVB-035 VOLCANO provides quiet operation, high suction capability, and long operational service life under severe engine room conditions.
