Product Detailed Description

YALAN 207 Mechanical Seal for Reactors, Drying Machine and Evaporators

Structural Features: double end, multiple springs, balanced, fixed rotary direction, with internal bearing, cartridge mechanical seal. The multi spring design make sure the load on the seal faces are balanced. The top of the seal has radial bearing which can decrease the unnecessary movement of the shaft. The seal tank has cooling jacket that optimizes the operating conditions of the seal. The locked screw transmission design has directivity and it is easy to install with reliable performance.

1. The top bearing should not be used as agitating support point.
2. When the medium temperature is above 180 ºC a cooling tank is needed to be installed, which will increase the operating height of the whole component by 80 mm.
3. When the pressure is above 0.3 MPa, auxiliary seal system is needed.
