The VBN, VBN-DS line heavy duty process pumps, available in double - casing or wet pitconfigurations, are multistage, diffuser type, fully designed according to latest edition of API 610 Std.Pump components geometry, optimised through hydraulic, structural, thermal and dynamic F.E.M.analysis, lead to an high product reliability. Particularly to avoid dangerous resonances, the F.E.M.dynamic analysis is carried out on all manufactured pumps taking into account the proper siteoperating conditions.
Main design features are:
■ Closed type impeller with front and rear wear rings as well as balancing holes, to minimise the axial thrust.
■ Large eye single suction or double suction 1st. stage impeller to meet low NPSH requirements.
■ Number of stages rangeable from 1 to 14.
■ Pump shaft in one or at the maximum two pieces, fully machined to respect the more restrictive run-out API limits.
■ As a standard, the rotor axial thrust is supported by a duplex oil lubricated ballangular contact type bearings.
■ Renewable bushings are provided at all interstage and columns.
■ Deep stuffing boxes, designed in accordance to API 682 Std., suitable to accept any type of mechanical or packing seal.
■ Labyrinths and deflectors at either bearing housing to maximise protection against dirt.
General informations
Main pumps applications refer to heavy duties on:■ fluid transport ■ pipeline ■ hydrocarbon booster ■ condensate extraction
