The actual working conditions of the high pressure fuel pump in the cylinder have the characteristics of high working temperature, high working frequency and fast change of pressure,
It is almost harsh on the requirements of the seals, requiring seals to withstand high temperatures (Engine temperature 100-160°C), optidur NC (The number of working life cycles reached one billion levels), Good follow-up (High working frequency and fast pressure change), Due to the limitations of seal performance indicators, most of the market share of the current global high-pressure fuel pump by Dr. Song and Hitachi brands.
The VS011 material seal developed by our company completely meets the working conditions of high pressure fuel pump. Through the actual work experience of many customers in Guangzhou and Beijing have achieved satisfactory results. High-pressure fuel pumps currently assembling our company's seals are already on the market.
