Vertical pump VD / VDL

Download Catalog

The VD and VLD Gabbioneta Pumps TM are vertical multistage, volute type, heavy duty prcess pumps, available in double- casing or wet pit configuration. Double suction 1st stage impeller permits to meet low NPSH requirements, while the closed type impeller with front and rear wear rings and balancing holes minimizes the axial thrust. Labyrinths and deflectors at both bearing housing covers maximize protection against dirt and pump shaft, in one or two pieces, is fully machined to respect the more restrictive run-out API limits. Additional rigid coupling, to facilitate mechanical seal maintenance activities, and axial thrust tilting pad bearings for ultra high thrust operating conditions can be provided.

  • Geometry of pump components optimised through hydraulic, structural, thermal and dynamic F.E.M. analysis to guarantee high product reliability
