Wilo-VeroTwin-DPL 80/120-4/2-IE3 double circulation pump 2155463

Efficient circulation pump for heating and cooling systems

The Wilo-VeroTwin-DPL 80/120-4/2-IE3 circulation pump is a reliable solution for demanding installations where efficiency and durability are key. The dual pump design provides redundancy and the ability to adjust performance to changing system needs. The device is characterized by high energy efficiency (IE3 class), which translates into lower operating costs. This makes it an ideal choice for both professional installers and users looking for long-term savings.

Design and application

The Wilo-VeroTwin-DPL 80/120-4/2-IE3 is a canned pump with an inline design and a DN80 flanged connection. Made of high-quality cast iron (GG 25), it provides corrosion resistance and long-term operation even in harsh conditions. The polypropylene impeller (PP-GF) guarantees mechanical strength and chemical resistance. The pump is designed for circulating water in heating, air conditioning, cooling systems and industrial installations. Its versatility makes it suitable for use in residential, commercial and industrial buildings. The IP55 protection class ensures safe operation even in humid environments.

Key features and benefits

• High efficiency: The maximum pump capacity is 139.4 m³/h, and the maximum head is 20.01 m, allowing for efficient operation in extensive installations.
• Energy saving: The IE3 class motor minimizes electricity consumption, reducing operating costs and environmental impact.
• Dual design: Two independent pumping circuits provide redundancy – in the event of a failure of one circuit, the other will continue to operate, maintaining the continuity of the system. Additionally, it allows for flexible adjustment of performance to current demand.
• Durable construction: The GG 25 cast iron body and PP-GF impeller guarantee resistance to corrosion and mechanical damage, ensuring a long service life.
• Wide temperature range: The pump can operate in a temperature range from -20°C to 120°C, making it suitable for a variety of applications.
• Easy installation and maintenance: The inline design with flanged connections facilitates installation and integration with the existing installation.
• Compliance with standards: Insulation class F and compliance with industry standards ensure safe and reliable operation of the device.
• Maximum operating pressure: 10 bar – ensures safe operation in standard installations.
• Rotational speed: 2900 1/min – optimal speed for efficient fluid flow.
