221,222 mechanical seal is a radial double-end mechanical seal for agitators, it is especially adapted axial size limited the workplace, 221 type is under strong corrosive medium, used in glass-lined reactor and so on; 222 To adapt to weak corrosive media, often with supporting the use of stainless steel and other vessel.
Scope of application: pressure (absolute pressure) 1.33 × 10-5 ~ 1.0MPa, the sealed chamber temperature ≤ 80 ℃, speed ≤ 500r/min.
221/CT, 222/CT up and down the basis for the increase in the prototype thermostat for -40 ~ 250 ℃ temperature range, the height increase of about 100mm, the other dimensions unchanged.
