Wilo-VeroTwin-DPL 50/120-1.5/2-IE3 twin circulation pump 2121252

Circulation pump for heating and cooling systems

The Wilo-VeroTwin-DPL 50/120-1.5/2 circulation pump is a reliable solution for installations requiring efficient liquid circulation. The dual pump design provides redundancy and the ability to adjust performance to current needs. The device is particularly recommended for use in heating, air conditioning and industrial systems where continuity of operation and energy efficiency are key. The pump body made of cast iron guarantees durability and corrosion resistance, and the polypropylene (PP-GF) impeller ensures efficient energy transfer.

Construction and application

The Wilo-VeroTwin-DPL 50/120-1.5/2-IE3 is a canned pump with an inline design and DN 50 flanged connections. This design simplifies installation in pipelines and minimizes the risk of pressure loss. The motor with a power of 1.5 kW and energy efficiency class IE3 translates into low operating costs. The pump is designed to operate with liquid at temperatures from -20°C to 120°C and in an environment at temperatures from -15°C to 40°C. Thanks to its high efficiency (MEI 0.4) and the ability to adjust the rotational speed (2900 1/min), the pump optimizes energy consumption and ensures user comfort.

Key features and benefits

• Dual design: Ensures independent operation and the ability to switch between pumps in the event of a failure or a need to increase performance.
• High energy efficiency (IE3): Reduces operating costs and minimizes environmental impact.
• Durable materials: The GG 25 (GJL-250) cast iron body and PP-GF impeller guarantee long life and corrosion resistance.
• DN 50 flanged connections: Facilitate installation and integration with the existing installation.
• Wide temperature range: Allows the pump to be used in various operating conditions (-20°C to 120°C).
• Protection class IP55: Protects the device from external factors such as dust and moisture.
• Maximum working pressure 10 bar: Guarantees safe operation in typical installations.
• Rotational speed 2900 1/min: Provides optimal performance at a nominal flow rate of 45.82 m³/h and a head of 115.23 kPa.
• Compliance with standards: The device meets the required safety and quality standards, confirming its reliability.

The Wilo-VeroTwin-DPL pump is an investment in an efficient and durable solution for your heating or cooling system, providing comfort for both the installer during installation and the end user for years to come.
