They can be used in console pumps to exclude high vibration.
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.
