The seal is made according to the drawing of the double mechanical seal.  
Radial plain bearing is located  between the stages of  the seal and operates on the barrier liquid of the mechanical seal.  
The rigidity of the shaft is increased because of the reduced size of the console and increased distance between the shaft supports.  


Shaft diameter, mm 22..200
Shaft rotation speed, rpm 30…4500
Temperature of sealed medium, °C -60…200
Pressure of sealed medium, MPa up to 10
Maximum leakage, l/h 0,002
