Wilo-VeroTwin-DPL 50/140-3/2-IE3 double circulation pump 2121254

Efficient circulation pump for heating and cooling systems

The Wilo-VeroTwin-DPL 50/140-3/2-IE3 circulation pump is a reliable solution for installations requiring efficient liquid circulation. The twin pump design provides high performance and the ability to operate in systems with variable flow requirements. The device is particularly recommended for use in public buildings, industrial facilities, and advanced heating and cooling systems.

Design and application

The Wilo-VeroTwin-DPL 50/140-3/2-IE3 is a canned pump with an inline design and flanged connection. This construction simplifies installation and integration with existing infrastructure. The pump is designed for pumping cold and hot water (according to VDI 2035) free of abrasive components. Therefore, it will be suitable for heating, water and cooling installations. Made of cast iron (housing) and polypropylene (impeller) ensures durability and corrosion resistance. The motor with energy efficiency class IE3 guarantees low energy consumption, which translates into operational savings.

Key features and benefits

• High efficiency: The maximum pump capacity is 73.19 m³/h, and the maximum head is 21.59 m, allowing for efficient operation even in extensive installations.
• Twin pump: The twin pump design provides redundancy and the ability to adjust performance to current system needs – backup or parallel operation increasing flow.
• Energy saving: The IE3 motor minimizes electricity consumption, reducing operating costs.
• Durability and reliability: The use of high-quality materials, such as cast iron and polypropylene, guarantees a long pump life and corrosion resistance.
• Wide range of applications: The pump is ideal for heating, water and cooling installations in public buildings, industrial facilities and single-family homes.
• Safety: The IP55 protection class provides protection against dust and water jets, allowing operation in harsh environmental conditions.
• Flanged connections: Allow easy installation and removal of the pump in the installation, and also ensure a tight connection with pipes with a diameter of DN 50.
• Pressure class PN 10: Ensures safe operation in systems with a maximum working pressure of 10 bar.
• Continuous operation: The ability to operate at an ambient temperature of -15°C to +40°C and a medium temperature of -20°C to +120°C enables the use of the pump in a wide range of working conditions.
