2018/8/7

285, 286 type mechanical seals, including rotating shaft supporting system and double face mechanical seal. The 285 type is suitable for 1.33 * 10-5 ~ 0.6MPa, and the 286 type is suitable for 1.33 * 10-5 ~ 1.6MPa. Temperature of sealing chamber is < 80, rotational speed is < 500 rpm. The actual height (L, L0, etc.) varies with the extension length of stirring shaft. Please pay attention to the design of the seal chamber and supply according to the specific size of the bottom flange.
The 288 type adopts the integral short shaft structure. The pressure is 1.33 *10-5~4.0 MPa, the temperature of the sealing chamber is less than 80, and the rotational speed is less than 500 rpm. The output end can also be designed with the integral shaft.
