Wilo-Helix V 618-1/25/E/KS/400-50 high-pressure water pump 4156056

High-Pressure Water Pump – Reliable Supply and Pressure Boosting

The Wilo-Helix V 618-1/25/E/KS/400-50 is a multistage vertical centrifugal pump designed for efficient water delivery in demanding installations. Its inline design with round ports simplifies installation and integration into existing systems. It performs reliably in water supply and pressure boosting applications, as well as in industrial systems, fire protection systems, and car washes.

Performance and Durability in Every Detail

This pump stands out with its robust construction and corrosion-resistant materials, ensuring long-term reliability even under harsh operating conditions. Impellers, guide vanes, and stage casings are made of stainless steel (1.4404 / AISI 316L), and the pump casing is also constructed from stainless steel (1.4404 / AISI 316L), guaranteeing reliability and resistance to aggressive media. The 4 kW motor (IE3 efficiency class) delivers high performance while maintaining energy efficiency. The pump’s maximum flow rate is 10 m³/h, with a maximum head of an impressive 158.9 m, enabling its use in a wide range of high-pressure applications.

Key Features and Benefits

• High Efficiency: Optimized hydraulic design minimizes energy losses and ensures efficient operation.
• Durability and Corrosion Resistance: Use of high-grade stainless steel (in various grades depending on component) ensures long service life, even when pumping contaminated or chemically aggressive water (in versions with appropriate seals).
• Easy Maintenance: Robust coupling cover provides easy access to serviceable components, reducing downtime.
• Wide Range of Applications: Ideal for water supply, pressure boosting, industrial systems, fire protection, and car wash installations.
• Safety: IP55 protection rating guards against dust and water jets, ensuring safe operation in diverse environmental conditions.
• Versatility: Compatibility with potable water (in EPDM seal versions) increases installation flexibility.
• Robust Connections: Stainless steel connections (DN 32) ensure leak-tight and durable joints.
