The VD and VLD centrifugal pump series are engineered to minimize NPSHr on high capacity vertical applications.
The VD and VLD Gabbioneta Pumps® are vertical multistage, volute type, heavy duty process 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.
The Gabbioneta VBN centrifugal pump series are designed to minimise axial thrust in low NPSH applications.
The VBN and VBN-DS Gabbioneta Pumps® are vertical multistage, heavy duty process pumps, available in double casing or wet pit configuration.
A wide range of sizes, number of stages and large eye suction or double suction 1st stage impeller, that allows to meet low NPSH requirements, complete the variery of the offered products.
The Gabbioneta AHPB pump series is built to reliably minimize axial and radial hydraulic thrust in high-temperature environments while resisting corrosion.
The AHPB, AHPB-DS Gabbioneta Pumps® are heavy duty double casing, multistage, radial split, with single or double 1st stage impeller pumps.
A wide range of sizes, number of stages combinations, various arrangements of suctions and discharge nozzles and three bearings arrangements and De-staged construction when required complete the variety of the offered products.
Gabbioneta DSA pumps offer axial balance, proven reliability and easy maintenance in the toughest conditions, including temperatures over 120 °C.
The DSA Gabbioneta Pumps® range are horizontal, between bearings with radial split casing and double suction impeller.
A wide range of sizes, various arrangements of suction and discharge noozzles and the three bearings arrangements available complete the variety of the offered procucts.
Gabbioneta DH and DDH process pumps, built for reliable service and easy maintenance, offer operational flexibility and stability in high temperatures.
The DH-DDH range Gabbioneta Pumps® are heavy duty horizontal, between bearings two stages pumps with radial split casing.
Two single suction back to back impellers for DH or a double suction first stage impeller, plus a second stage with bilancing drum for DDH, assure adequate axial thrust balance and allow to accept any type of balanced mechanical seals, in accordance with API 682 Stdandard.
Gabbioneta AXD/AXDD pumps offer easy maintenance and proven reliability for the tough conditions found in refineries and petrochemical plants.
The AXD-AXDD range Gabbioneta Pumps® are heavy duty horizontal, between bearings axial split casing pumps with single or double suction first stage impeller and, for AXDD, a second single suction impeller, with suction and discharge nozzles, integrally cast with the casing, arranged in in-line configuration.
The Gabbioneta RL range process pumps offer dedicated hydraulic designs to meet very low flow conditions.
The RL range Gabbioneta Pumps® are horizontal, radially split, centerline supported, single entry overhung pumps, designed in a back pull-out cofiguration for easy maintenance, centerline feet mounting for high temperature stability. RL pumps are specifically designed for low flow operations, featuring open Barske type impeller with radial vanes.
The all-around Gabbioneta R range process pumps provide superior efficiency for more than 100 different hydraulic configurations suitable for heavy-duty use.
The R Range Gabbioneta Pumps® are overhung horizontal radially split, centerline supported heavy duty process pumps, designed in a back pull-out configuration for easy maintenance and centerline feet mounting for high temperature stability.
The coverage includes more than 100 different hydraulics, for optimum efficiency over a wide operating range.
Shaft flexibility index is fully in compliance with API 610 Annex K and twin volute configuration minimises radial loads.
This Gabbioneta Pumps® series offers reliable operation, easy internal inspection and maintenance while reducing axial and radial loads.
The AHP and AHP-DS range Gabbioneta Pumps® are heavy duty process multistage pumps, horizontal, between bearings, volute type pumps, with axial split casing that allow easy internal inspectability and maintenance and single or double entry 1st stage impeller.
Opposed impellers configuration allow to minimise axial thrust.
Built for easy maintenance and long life, Gabbioneta DSIL pumps minimize axial and radial load while meeting tough NPSH requirements.
The DSIL range Gabbioneta Pumps® are heavy duty process vertical in-line overhung pumps, with double suction impeller designed in a back pull-out cofiguration for easy maintenance activities without motor removal.
Suction and discharge noozzles are integrally cast with the casing and double volutes minimise radial loads, for extent pump life.
Double suction, axially balanced, closed type impeller, with front and rear wear rings, allow to meet very low NPSHr.
As option, pumps can be equipped with heavy duty bearing housing, anti-reverse rotation device, steam jackets and casing insulations.
Gabbioneta VI are VS4 robust process pumps specifically designed to minimise overall dimensions
The VI Gabbioneta Pumps® are vertical, single stage heavy duty process pumps, with side discharge.
VI pumps have closed type impeller with front and rear rings as well as balancing holes, to minimise the axial thrust, and large eye to meet low NPSH requirements.
Pump shaft is fully machined to respect the most restrictive run-out API requirements, labyrinths and deflectors at both bearing housing covers allow to maximize protection against dirt and discharge column mounted with a sliding fit through the sole plate accounts for thermal expansions.
As option, can be provided full jacketed contruction to minimize pump distortions caused by local heating, additional rigid coupling to facilitate mechanical seal maintenance activities, suction strainer for particularly dirt services and open impellers for waxy or fibrous solids.
