Suitable for diesel engine fuel piping; also obtained type approval from the Fire Safety Center.
Currently, flexible hoses cannot absorb the following movements: - Pulsating pressure and shock pressure from pumps, etc. - Movements in the direction of expansion and contraction. However, these movements frequently occur in piping systems everywhere. To solve this problem, we developed the "NFK-PG Series." By using a multi-layer structure with fluororesin inside, we have made it possible to accommodate not only the movements of conventional flexible hoses but also pulsating and expansion/contraction movements. Leveraging this performance, we have obtained performance evaluation from the Japan Fire Equipment Safety Center for flexible hose joints suitable for diesel engine fuel piping, which were previously difficult to address with conventional fire law flexible hoses. We encourage you to use this for "emergency diesel engines" that serve as emergency power sources during power outages, drive sources for disaster prevention fire pumps, and drive sources for river water level adjustment pumps.
