Wilo-Helix V 208-1/16/E/KS/400-50 high-pressure water pump 4161710

High-pressure water pump Wilo-Helix V 208-1/16/E/KS/400-50

This is a multi-stage, vertical centrifugal pump designed for water supply, pressure boosting, and industrial applications. The inline design and robust coupling guard facilitate installation and maintenance. The pump is characterized by high efficiency and reliability, and its components made of stainless steel ensure corrosion resistance. This model is particularly well-suited for use with potable water thanks to stainless steel parts in contact with the medium (EPDM version).

Performance and application

The Wilo-Helix V 208-1/16/E/KS/400-50 pump offers a maximum flow rate of up to 4 m³/h and a maximum head of 58.52 m. It will be useful in various installations, including:

• Water supply and pressure boosting.
• Circulation installations in industry.
• Process water systems.
• Closed cooling circuits.
• Fire protection systems.
• Car washes.
• Irrigation systems.

Thanks to the ability to pump water with solids up to 10 mm in diameter, the pump is versatile and can be used in applications requiring pumping of contaminated liquids.

Design and materials

The pump is designed for durability and reliability. Key components are made of high-quality materials:

• Pump casing: Stainless steel 304 (1.4301) or 316L (1.4404) – provides corrosion resistance and long life.
• Impeller: Stainless steel 304 (1.4307) or 316L (1.4404) – guarantees efficient pumping even in difficult conditions.
• Shaft: Stainless steel 1.4301 or 1.4462 – ensures stability and mechanical strength.
• Seal: EPDM or FKM – matched to the type of medium, ensuring the tightness and reliability of connections.

The pump motor has an energy efficiency class of IE3, which translates to lower electricity consumption and reduced operating costs. The motor output power is 0.75 kW, and its rated voltage is 230-400 V at a frequency of 50 Hz. The IP55 protection class protects the device against dust and water jets, allowing it to operate in various environmental conditions. The ambient temperature range is from -15 to +50°C, and the fluid temperature from -30 to +120°C (depending on the seal version). The maximum operating pressure is 16 bar, and the diameter of the inlet and outlet connections is 1 inch (25 mm).
