Fuel pump Suntec E6NA 1070 7P

The Suntec E 6 N A 1070 oil pump is a high-performance device equipped with an integrated pressure-regulating valve that not only maintains the required fuel pressure but also provides a secure fuel shut-off when needed. Its design is largely based on the proven solutions of the J series pumps; however, the E series features extended functionality. This allows the pump to operate safely and efficiently not only with diesel fuel but also with heavier liquid fuels, including fuel oil and other medium-viscosity fuels. Such versatility makes it an ideal choice for both industrial and residential fuel supply systems, ensuring reliable and consistent operation across a wide range of working conditions.
