Wilo-Helix V 411-1/25/E/KS/400-50 high-pressure water pump 4160531

High-pressure water pump Wilo-Helix V 411-1/25/E/KS/400-50

This is a multi-stage, vertical centrifugal pump designed for efficient water pressure boosting in various applications. The inline design with round connections simplifies installation in existing systems. The pump is characterized by high efficiency and reliability, making it an ideal solution for both professional installers and end-users. Made of high-quality materials, including stainless steel, it ensures long-lasting and trouble-free operation.

Construction and application

The Wilo-Helix V 411-1/25/E/KS/400-50 pump is widely used in water supply and pressure boosting systems, industrial installations, fire protection systems, as well as in car washes and irrigation systems. Thanks to its robust construction and corrosion-resistant materials, it can also be used for pumping water contaminated with solid particles up to 10 mm in diameter. The pump body optimized for flow minimizes hydraulic losses and increases work efficiency. It is worth noting that the design is easy to maintain thanks to a solid coupling cover.

Key features and benefits

• High performance: The maximum pump capacity is 6.5 m³/h, and the maximum head is 87.12 m, allowing for efficient satisfaction of the needs of even demanding installations.
• Durable construction: Made of high-quality stainless steel (pump body – stainless steel 304 (1.4301), impeller – stainless steel 304 (1.4307)) guarantees corrosion resistance and long service life.
• Wide temperature range: The pump can operate in an ambient temperature range from -15°C to 50°C and pump liquid with a temperature from -30°C to +120°C (depending on the version).
• Safety: IP55 protection class provides protection against dust and water jets, allowing the pump to be installed in various environmental conditions.
• Energy efficiency: IE3 class motor ensures high energy efficiency, which translates into lower operating costs.
• Easy installation: The inline design with round connections simplifies the integration of the pump with the existing hydraulic installation.
• Motor power: 1.5 kW provides sufficient power to operate under various load conditions.
• Connections: Both the inlet and outlet connections are made using a flange with a nominal diameter of DN 25 and a pressure class of PN 25 – a standard solution that facilitates integration with existing pipeline systems.

The Wilo-Helix V pump is a reliable solution for demanding applications, combining high performance with durability and ease of use.
