221,222 series mechanical seals

2018/8/7

Type 221 and 222 mechanical seals are radial double-face kettle mechanical seals, which are especially suitable for work occasions with limited axial dimension. Type 221 is a strong corrosive medium, which can be used in glass-lined reaction kettles and so on. Type 222 is suitable for weak corrosive medium, and is often used in combination with stainless steel kettles.
>>Scope of application: pressure (absolute pressure) 1.33 * 10-5 ~ 1.0MPa ，The temperature of the sealing chamber is less than 80 degrees, and the rotation speed is less than 500r/min.
>>221/CT and 222/CT are thermostats on the basis of the prototype. They are suitable for the temperature range of - 40 ~ 250 ~C. The height increases by about 100 mm, and the other sizes remain unchanged.
