The Portapump unit is a rugged, all-weather fuel pump designed for the rapid fuelling or de-fuelling of all types of aircraft or vehicles using jet A1 or diesel with a flash point above 37ºC. It is designed to be easily transported by aircraft, helicopter or vehicle. Able to be carried by one man, it uses a powerful 24–28 volt DC motor direct coupled to a high speed pump with phosphor bronze sliding vanes. The power source can be any 24/28 volt supply such as a portable GPU, vehicle battery or aircraft DC bus. Alternatively a 110/220 volt domestic mains supply can be used with a DC voltage converter.
