This multistage, vertical centrifugal pump from the Wilo-Helix V series is a robust solution for water supply, pressure boosting, and industrial applications. The pump design is optimized for flow and efficiency, and its durable components ensure reliable operation in demanding conditions. Model 426-1/25/E/KS is characterized by high performance and the ability to pump liquids with temperatures up to 120°C.

Design and application

The Wilo-Helix V pump is designed to work with clean or slightly contaminated water containing solids up to 10 mm in diameter. It will be suitable for irrigation systems, car washes, fire protection installations, as well as water treatment and cooling liquid circulation processes. Thanks to its Inline design, the pump is easy to install and integrate with existing installations. Made of high-quality materials – stainless steel – it ensures long-lasting and trouble-free operation.

Key features and benefits

• High efficiency: The maximum pump capacity is 6.5 m³/h, and the maximum head is 208.2 m, allowing for efficient water pumping even to great heights.
• Durable construction: The pump body made of stainless steel (grade 304 or 304L depending on the version) provides corrosion resistance and long life. Impellers and diffusers are also made of stainless steel (grade 304L or 316L), which further increases the durability of the device.
• IE3 motor: Equipped with an IE3 energy efficiency class motor, which translates to lower energy consumption and operating costs. The motor power is 4 kW at a voltage of 400 V and a frequency of 50 Hz.
• Wide temperature range: The pump can operate with a liquid temperature from -30°C to +120°C (depending on the EPDM version), making it a universal solution for various applications.
• IP55 protection class: Provides protection against dust and water jets, allowing the pump to be installed in various industrial environments.
• Flanged connections: Equipped with flanged connections DN25 on the suction and discharge sides, compliant with EN 1092-1 standards, which facilitates integration with existing piping installations.
• Solid coupling guard: The pump design is designed to ensure easy maintenance thanks to a solid coupling guard.
• Maximum working pressure: The pump is designed to operate at a maximum working pressure of 25 bar.

The Wilo-Helix V pump is a reliable device for professionals and end customers looking for an efficient and durable solution for pumping water in various industrial and commercial applications.
