Vertical multi-stage centrifugal pump with the suction port and the discharge port at the same level. The pump head and the base are made of cast iron. All other components in contact with the liquid are made of stainless steel (EN 1.4301).

CRN 3-31 S-P-A-V-HQQV The non-self-priming high-pressure multi-stage vertical centrifugal pump with the suction and discharge ports at the same height (flush) can be conveniently installed into a horizontal single-pipe system. The stuffing box is inverted to ensure that the shaft seal is not affected by the higher pump discharge pressure. The multi-stage vertical centrifugal pump with the suction and discharge ports at the same height (flush) can be conveniently installed into a horizontal single-pipe system. Electrical energy is transmitted through a split coupling. The connection of the pipeline is achieved through a PJE (Victaulic®) coupling.
