Glandless centrifugal multi-stage pumps
Pumps of the following type are intended for usage mainly in technological and transport systems for feed supply, transport and distribution of petroleum refinery products, gas condensate, liquefied hydrogen gases, petrol etc.
Types and the main specifications of the pumps are given in table 1 and their graphical specifications on Fig. 2.
Pumps, as a rule, are produced with remote electric motor intermediate bearing assembly of leading magnetic clutch drive (version Б). Pump rotor is discharged of axial forces and rotates in the plain bearings lubricated by the pumped environment (Fig. 1).
