The development of HERMETIC pump systems depended on the solution of a central problem, namely the elimination of axial thrust at the rotor equipment . The various fluid properties exclude the possibility of using mechanical axial bearings . The only generally valid solution to this problem thus lay in hydraulic balance of the rotor .
With canned motor pumps the axial position of the pump shaft is automa- tically regulated during operation to achieve a self-created balanced condition and thus, there are no effects by axial forces on the axial bearing collar .
The technical design of the axial thrust balancing generally depends on the construction size and stage number of the respective pump as well as on the liquid to be conveyed .
