Grundfos pressure group CMBE TWIN 3-62 I-U-C-C-D-A

The Grundfos CMBE TWIN 3-62 I-U-C-C-D-A pressure boosting system is a high-performance system designed for increasing pressure in both domestic and commercial applications. This pressure boosting system includes two Grundfos CMBE pumps connected in parallel, ensuring a constant and reliable water pressure, ideal for commercial buildings, single-family homes, and other facilities that require a constant and efficient water supply.

This system is specially designed to supply clean water with efficient and economical operation, automatically adjusting to the pressure needs of the system thanks to its integrated frequency converter. This allows for significant energy savings by reducing the pump speed when water demand decreases and increasing the speed when a higher flow rate is needed, providing intelligent and efficient operation.

The Grundfos CMBE TWIN 3-62 is built with high-quality materials, such as AISI 304 stainless steel, both in the pump body and in the impeller, ensuring great resistance to corrosion and a long service life of the system, even in demanding conditions. This makes it a reliable choice for projects where durability and strength are essential.

Main product features:

• Two pumps in parallel: This twin pump design provides greater stability and redundancy, ensuring a constant water supply even in high-demand situations.
• Integrated frequency converter: Automatically adjusts the pump speed based on demand, optimizing energy consumption and maintaining constant pressure at all times.
• High-quality material: The pump body and impellers are made of AISI 304 stainless steel, ensuring excellent corrosion resistance and greater durability.
• Suitable for drinking water: Complies with certifications and approvals for drinking water use, such as CE, UBA, EAC.
