the foundation of the company

Pompe Gabbioneta has been engaged in design and

The AHP AHP-DS line heavy duty process pumps are multistage, horizontally split, diffuser type with single or double entry 1^ststage impeller, 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.

The "modular design" philosophy permits to cover a wide range of applications replacing the main hydraulic components i.e. only impeller/diffuser. Casing, shaft, mechanical seals, bearing frames result therefore fully interchangeable and reusable.

A wide range of sizes, number of stages and material combinations complete the variety of the offered product.

Main design features are:

■ Opposed impeller and diffuser configuration to minimise axial and radial hydraulic thrusts.

■ Large eye single suction or double suction 1^st stage impeller to meet low NPSH requirements.

■ Hydraulic performances checked on a Single Stage Test Equipment. This is particulary useful to verify the effective 1^st stage NPSH.

^■ Easy internal inspectability and maintenance.

■ Number of stages rangeable from 4 to 13.

■ "Stiff shaft design". Rotor operates below it's 1^stwet critical speed.

^■ Central and lateral balancing drums adequately shaped to optimise pump rotordynamic behaviour.

■ Side-Side suction and discharge nozzles integrally cast on lower casing half.

■ Near centerline casing mounting for high temperature stability.

^■ Contoured grafoil or glassfiber gasket to assure joint between casing halves and eliminate interstage leakages.

■ Deep stuffing boxes, designed in accordance to API 682 Std., suitable to accept any type of mechanical or packing seals.

■ Labyrinths and deflectors at either bearing housing to maximise protection against dirt.

^■ Three bearings arrangements available:

1. Ball Radial / Ball Thrust

2. Sleeve Radial / Ball Thrust

3. Sleeve Radial / Tilting Pads Thrust (Kingsbury Type).

manufacture of high quality centrifugal pumps.

The products and the markets served progressively changed from water to chemical industry and finally,

in the last thirty years, to API 610 heavy duty pumps for refinery and petrochemical industries.

The product development is based on a thorough interchange of marketing and operating experience

within the company and in close cooperation with project and plant engineers.

The manufacturing is made in a factory equipped with several modern cnc machines and machine tools,

special note has to be given to the machining centers where pump casings can be machined

completely with only two settings.

In house facilities are designed to meet the performance and NPSH testing requirements of all pumps manufactured in the company in full compliance with API 610 standards.

A quality assurance system certified in accordance with ISO 9001 is granting the achievement of highest quality for manufactured pumps.
