They offer a delivery capacity of up to 3.5 m3/h, a head of up to 6.5 m, and a power range of 20 kW to 40 kW. The pump body is made of cast iron, suitable for water circulation in heating and air-conditioning systems.

TCB-TCS Series
This series is intended for hot water circulation in residential systems, available in bronze (TCB) or stainless steel (TCS) versions. They provide a delivery capacity of up to 6 m3/h for single pumps and up to 9.5 m3/h for twin pumps, with a maximum operating pressure of 10 bar and a temperature range of 0°C to +110°C.

TC-FC Series
Designed for commercial systems, these circulators offer a delivery capacity of up to 68 m3/h for single pumps and up to 125 m3/h for twin pumps. They can handle a head of up to 20 m and operate with both single-phase and three-phase power supplies. The pump body is constructed from cast iron, suitable for non-aggressive hot or cold water circulation.

Performance and Dimensions
The document includes detailed tables of hydraulic performance and dimensions for each series, specifying delivery (Q) and total head (H) in meters, along with power and speed ratings. These tables are crucial for selecting the appropriate pump based on specific system requirements.

Applications
Each series is designed for specific applications, such as residential heating and air-conditioning systems, sanitary hot water systems, and commercial water circulation. The materials used, such as cast iron, bronze, and stainless steel, ensure durability and compatibility with various water types.

FC-FCT Series Overview
This series of centrifugal pumps is designed for various applications including water supply, heating, cooling, and general industry. The pumps are available in single (FC) and twin (FCT) versions, with options for different materials and configurations.

Specifications
The pumps offer delivery rates up to 190 m3/h for 2 poles and 330 m3/h for 4 poles, with a head up to 89 m for 2 poles and 35 m for 4 poles. They support both three-phase and single-phase power supplies at 50 and 60 Hz, with power ranging from 0.25 kW to 22 kW. The maximum operating pressure is 10 bar for PN10 versions and 16 bar for PN16 versions, with liquid temperature ranges from -10°C to +130°C for "E" versions and -20°C to +140°C for "S" versions.

Materials
The pump body is made of cast iron, while the impeller is made of AISI 316 stainless steel for certain models and cast iron for others. The adapter can be aluminum or cast iron, and the mechanical seal options include Carbon/Ceramic/EPDM and Silicon-carbide/Carbon/EPDM.

Applications
The pumps are suitable for water supply, heating, ventilation, cooling, chilling, general industry, and heat recovery. Optional features include a version with a Hydrovar frequency converter, an FCS with an efficiency class 1 motor, and a version with a bronze impeller.

Performance Tables
The document includes detailed hydraulic performance tables for various models at 50 Hz, 2 poles, and 4 poles, indicating the delivery (Q) and total head (H) in meters for different power ratings (kW and HP).

Operating Characteristics
The operating characteristics are provided for both 2 poles and 4 poles at 50 Hz, with notes on NPSH values and performance conditions for liquids with specific density and viscosity.

FCE4, FCS, FCS4, and FCTE Series Overview
This section details the specifications, dimensions, and weights of various pump series, focusing on their disassembly, dimensions, and component specifications.

Specifications
The document provides detailed specifications for pump bodies with and without foot, including series 125, 160, 200, and 250. It lists the dimensions and weights for each pump type, specifying parameters such as diameter (DNA, DNM), height (H), length (L), and weight (kg).

Procedures
The document outlines the clearance required for disassembly of pump bodies, both with and without foot. It specifies the necessary space and tools needed for maintenance and repair operations.

Standards and Norms
The catalogue includes standard specifications for pump flanges, holes, and thicknesses. It also details the connectors for air valves, pressure gauges, and drains, ensuring compatibility with industry standards.

Recommendations
Recommendations for handling and installation are implied through the detailed dimensions and weights, ensuring that users can select the appropriate pump type for their specific needs.
