mechanical seal for cryogenic(-104 C) vertical pump (VS6)

[danyel231]

we have a vs6 type pump with Ethylene service at -104 C temp., vapor pressure at operating temperature is 1 bara and the question is what arrangement and seal plan (base on API 682 4th) is suitable for this condition? which type of seal we should use?(Type A,B,C)

Why not contact a reputable seal manufacturer or their agent?
