TB2-M

Product catalog summary

Introduction
This document provides comprehensive technical specifications and operational guidelines for pressure groups equipped with horizontal electric pumps. These systems are specifically designed for water pressurization and distribution across civil, agricultural, and industrial installations.

Applications
The systems are utilized in heating, cooling, air-conditioning, and irrigation systems. They operate in a sequential cascade to accommodate increasing water demand, ensuring continuous operation even if one pump fails.

Specifications

Fluid Compatibility: Suitable for non-aggressive fluids both chemically and mechanically.
Temperature Range: Operates with pumped liquids between -15°C and 50°C.
Maximum Operating Pressure: 8 bar.
Maximum Starts per Hour: 20.
Installation Conditions: Indoor installation with ambient temperatures from 0°C to 40°C, humidity up to 50%, and altitude up to 1000 meters.
Noise Level: Maximum 81 dBA.
Performance: At 2900 rpm, maximum flow (Qmax) is 20, and maximum head (Hmax) is 92 m (Q=0).

Performance Tolerances
The pumps comply with UNI EN ISO 9906 Appendix A, and motors comply with IEC 60034-1 standards.

Group Composition
The system includes two self-priming centrifugal electric pumps, a base with adjustable anti-vibration feet, a control panel, suction and delivery manifolds, pressure switches, gate valves, check valves, and other components.

Pump Features
The pumps are self-priming with a cast iron body, brass or thermoplastic resin impeller, and a mechanical seal in carbon/ceramic. They feature a totally enclosed fan-cooled motor, protection class IP44 (IP55 available on request), and insulation class F.

Control Panel Features
The electro-mechanical control panel supports both three-phase and single-phase power supplies, with protective and operational components such as magnetothermal switches, relays, transformers, and pilot lamps.

Optional Accessories
Accessories include diaphragm tanks, float switches, minimum pressure switches, and level relays with water shortage signals.

Special Versions
Special versions with electronic control panels are available upon request.

Materials and Components
The document details materials used in the hydraulic system, including galvanized and stainless steel (AISI304) and nickel-plated brass for various components like control panel columns, manifolds, and valves.

Hydraulic Features
Hydraulic characteristics for different pump models (TB2-M series) are provided, including performance curves and dimensions, based on a kinematic viscosity of 1 mm²/s and a density of 1000 kg/m³.

Dimensions and Weights
Standard dimensions and weights for various pump models are provided, with optional configurations for check valves and control boxes.

Performance Curves
Performance curves for pumps running individually and in pairs are included, with specifications for different models. The curves are based on standard conditions and include a safety factor for NPSH.

Operating Conditions
The system is designed for non-aggressive fluids, with a liquid temperature range of -15°C to 50°C and a maximum operating pressure of 7 bar. It should be installed indoors, with ambient temperatures between 0°C and 40°C, and a maximum altitude of 1000 meters.

Electrical and Mechanical Features
The system includes two self-priming centrifugal pumps, a cataphoresis-coated base with adjustable feet, an electrical control panel, and various valves and fittings. The pumps are made from stainless steel (AISI304) with optional thermoplastic or stainless steel impellers.

Control Panel Features
The electromechanical control panel is designed for two-pump pressurization systems, with options for direct start or star-delta configurations. It includes protective switches, alternation relays, and a transformer for auxiliary services.

Procedures
The operation is described as a sequential cascade following increased water demand, with automatic alternation between the main and secondary pumps. In case of a pump failure, the second pump ensures continued operation.

Recommendations
Optional accessories such as diaphragm tanks, float switches, and pressure switches are recommended for enhanced functionality. Special versions with electronic control panels are available upon request.
