Applications
The DELTA aluminium fuel unit type A is an efficient and modern oil burner pump, provided with bilateral delivery ports. Hub and shaft sizes are manufactured to international standards (EN 225-1), so it can be fitted to every oil burner. The pump type A is designed for pumping oil in high pressure oil burners and transfer pump applications. Its features allow an easy pump replacement with every other type of oil pump: the same unit is provided with nozzle port in both the left and right sides.Technical specifications
