Beschreibung
Zusammenfassung:	A multi-stage centrifugal pump has a main side plate of last stage at the side of side pocket, this is equipped with unit for purification of liquid being pumped with removal of mechanical admixtures. Stator bushing of additional cylindrical orifice hole of hydraulic balancing device is installed in pressure head with possibility of its radial displacement by means of adjusting screws. End gasket is provided with unit for prevention of contact of springs of the end gasket with outer liquid leakages through its friction pair and additional end-capping gasket, and chamber between additional end-capping gasket and friction pair of the end gasket is connected to inlet or pressure chamber of the pump.
