Product catalog summary

Applications

For drinking water and industrial purposes
For sea water
For automatic systems with hydrofore tank
For conveying acid and alkaline liquids, petrol, and light oils
For condensate and liquids with vapours
For food and pharmaceutical products

Design Features

BT pumps are self-priming side channel multistage pumps with star-shaped impellers that are hydraulically balanced to reduce axial thrust on the bearings. The bearings are external and life grease lubricated. These pumps have a low NPSHr value, allowing operation with suction lift up to 8 meters. They are suitable for transferring liquid-gas/vapour mixtures. Basic design pumps are mechanically sealed, with the option for double mechanical seals for handling hot, toxic, aggressive, and corrosive media.

Operating Pressures and Temperatures

Up to 120°C: 40 bar
Above 120°C: 16 bar
Max operating temperature with mechanical seal: 160°C
Minimum operation temperature: -10°C

Materials

Construction materials include cast iron, various types of bronze, and stainless steel. Special constructions are available according to Naval Rules, including shock-proof, noise-proof, vibration-proof, and non-magnetic versions.

Dimensions and Weights

The document provides detailed dimensions and weights for various pump models, indicating that dimensions and weights are not binding and flanges are according to UNI PN40 standards.

Performance Table

The performance table provides data for liquids with a viscosity of 1 centistoke and specific gravity of 1 Kg/dm3. It includes capacity and power requirements for different pump models at various flow rates.
