Pompe Gabbioneta has been engaged in design and

The DH and DDH line pumps are horizontal, two stage between bearings with a radial split casing. Single (DH line) or double (DDH line) suction impellers are fully designed according to latest edition of API 610 std.

A wide range of sizes and material combinations complete the variety of the offered product. Main design features, are:

■ DH pumps, with two single suction back to back impellers, to ensure the adeguate axial thrust balance.

■ DDH pumps, with a double suction 1 st. stage impeller, balanced by means of back wear ring on the 2nd stage impeller.

■ Suction and discharge nozzles, integrally cast with the casing, are normally arranged in top-top position, but side-top or side-side nozzle arrangements are available.

^■ Ample balancing line from 2nd. stage to suction maintain stuffing box pressures within limits easily acceptable by any type of balanced mechanical seals.

■ Centerline casing mounting for high temperature stability.

■ Stiff shaft design. Rotor operates below 1 st critical speed.

■ 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.
