Wilo-Helix V 1611-1/25/E/KS/400-50 high-pressure water pump 4141161

High-pressure water pump Wilo-Helix V 1611-1/25/E/KS/400-50

This is a high-performance, multi-stage centrifugal pump designed for water supply, pressure boosting, and industrial applications. The pump's design, optimized for flow and net positive suction head, ensures reliable operation in demanding conditions. Made of high-quality stainless steel, it guarantees durability and corrosion resistance.

Construction and application

The Wilo-Helix V pump features a vertical design with inline connections, making it easy to install and integrate with existing systems. It finds application in:

• Water supply and pressure boosting.
• Industrial installations – water circulation.
• Fire protection systems.
• Car washes and irrigation systems.
• Cooling circuits.
• Water treatment – as an element of water purification systems.

Thanks to its robust construction and corrosion-resistant materials, the pump is ideal for use with clean water or liquids with a small amount of solids (up to 10 mm in diameter).

Key features and benefits

• High efficiency: The multi-stage design provides efficient water pumping at high pressure.
• Durability: The pump body made of stainless steel 1.4404 (AISI 316L) and impellers and diffusers made of stainless steel 1.4404 (AISI 316L) guarantee a long service life even in difficult operating conditions.
• Reliability: A solid coupling cover provides easy maintenance and minimizes the risk of failure.
• Wide temperature range: The pump can operate in a temperature range from -30°C to +120°C (depending on the seal version).
• High working pressure: The maximum working pressure is 25 bar, allowing the pump to be used in demanding installations.
• IE3 motor: The use of an IE3 energy efficiency class motor translates into lower electricity consumption.
• Easy servicing: The pump design has been designed with convenient access to elements requiring regular inspection or replacement.

The pump is designed to operate with a voltage of 400 V and a frequency of 50 Hz, and its motor output power is 7.5 kW. The IP55 protection class provides protection against dust and water jets, allowing the pump to be installed in various industrial environments. The embedding length is 300 mm and the pump height is 159 mm. The inlet and outlet connections are DN50 flanges with a pressure class of PN25 made of stainless steel 1.4301 (AISI 304).
