螺杆泵改造，有没有超过200℃的高温密封啊！求推荐，输送渣油用的

是指改造机械密封吗，温度没有问题，只是这介质粘度？挺麻烦得

不知道你是改造那一块，关于温度动静环石墨的耐温是没问题的，不过浸锑石墨一般用的温度高点，亲呋喃树脂温度低点；牵涉更改介质，要看粘度了，其实粘度大的还是稠油泵好用，粘度小了就不好改了:) :(

没问题，我们以前导热油泵，温度220度，用的是丹东克隆的机械密封，辅助密封采用石墨垫片，是波纹管的机械密封，正常使用寿命一般在一年以上。

介质渣油，用金属波纹管不太好吧！

渣油很黏，波纹管单端面机械密封采用PLAN32冲洗方案比较好，我这里用的美国福斯的，300多度，克隆也有！

这个不难吧？九十年代初渣油泵就在用了，波纹管机械密封
