Direct pump group ESBE GDA211 25-WILO 61001100

Universal pump group ESBE GDA211 – an effective solution for installers and users

The ESBE GDA211 25-WILO pump group is a ready-to-install device designed for direct energy transport in heating systems. It is characterized by high efficiency and reliability, which translates into user comfort and energy savings. The construction based on high-class components, including an energy-saving Wilo pump, guarantees long-lasting and trouble-free operation.

Construction and application

The GDA211 pump group is equipped with a number of elements ensuring optimal operation of the installation: two shut-off valves with clear thermometers, a check valve preventing backflow of the medium, and high-quality thermal insulation minimizing heat loss. The device is designed to work with glycol, which expands its range of applications. Thanks to its compact dimensions (width 250 mm, height 379 mm, depth 146 mm) and the possibility of wall mounting, the ESBE GDA211 pump group will work even in limited space. Connections with a diameter of 1 1/2 inch (40) on the primary side and 1 inch (25) on the secondary side ensure compatibility with most heating installations.

• High pump efficiency Wilo: Provides efficient circulation of the heating medium, reducing operating costs.
• Check valve: Protects the pump from damage and ensures proper flow of the medium.
• Thermometers: Allow for continuous monitoring of the heating medium temperature.
• Thermal insulation: Minimizes heat loss and increases the energy efficiency of the system.
• Expandability: Compatibility with manifolds allows for easy adaptation of the pump group to more complex installations.
• Durable construction: The use of materials such as brass and steel guarantees the longevity of the device.
• Maximum working pressure 10 bar: Ensures safe operation under standard operating conditions.
• BSPP connection threads: Facilitate installation and connection to the existing installation.

Key technical parameters for professionals

The ESBE GDA211 pump group is characterized by a working temperature range from 5 to 100°C and has a built-in circulating pump with a mounting length of 130 mm. The housing made of plastic provides resistance to corrosion and mechanical damage. The device is adapted to work with glycol, making it an ideal solution for installations protected against freezing. Additionally, the presence of a pump ball valve facilitates servicing and maintenance of the device without the need to disassemble the entire pump group. The pump meets the requirements of EC 547/2012 and EC 641/2009 standards regarding high energy efficiency.
