Trillium Italy BB5 Pump Range

Our Supplier have two pump factories in Italy, where Gabbioneta produces small to medium size BB5 pumps and Termomeccanica produces medium to big BB5 pumps. Both can deliver with NORSOK approved materials.

Gabbioneta BB5 series is built to reliably minimize axial and radial hydraulic thrust in high-temperature environments while resisting corrosion.

These Gabbioneta BB5 pumps are heavy-duty, double casing, multistage, radial split pumps with single or double first stage impellers. This series offers a wide range of sizes with a number of stages combinations, with various arrangements of suction and discharge nozzles. When required, three bearings arrangements and de-staged construction complete the vast variety of this product offering.

Termomeccanica BB5 pumps are between bearings, double casing, radially split, and multistage with a diffuser design. A full cartridge pull-out solution is standard for simple and efficient dismantling. The MESBD models are first stage double entry impeller for low NPSH applications. A bolted discharge cover design is available. For high stage numbers, a back-to-back arrangement is adopted. A bleed off nozzle can also be provided. The hydraulic axial thrust is compensated by a balancing drum. Antifriction or hydrodynamic bearings can be supplied based on operation parameters.
