Wilo-Helix V 409-1/16/E/KS/400-50 high-pressure water pump 4160526

High-Pressure Water Pump – Reliable Solution for Water Supply and Pressure Boosting

The Wilo-Helix V 409-1/16/E/KS/400-50 is a multistage vertical centrifugal pump designed for demanding applications. Its inline design and robust construction from corrosion-resistant materials ensure reliable operation and long service life. It performs excellently in both industrial systems and water supply, pressure boosting, and irrigation applications.

Construction and Applications

This pump is engineered to handle water, including water contaminated with solid particles up to 10 mm in diameter. It is suitable for:

• Water supply and pressure boosting systems
• Industrial installations – circulation of process and cooling water
• Fire protection systems
• Car washes and irrigation systems
• Closed-loop cooling circuits

The pump features a solid stainless steel casing that provides excellent corrosion resistance and long-term durability. The impeller and diffuser are manufactured from high-grade stainless steel, further enhancing the pump’s longevity. High hydraulic efficiency is achieved through optimized flow design and favorable net positive suction head (NPSH) values.

Key Features and Benefits

• High Performance: Maximum pump capacity of 6.5 m³/h and maximum head of 70.67 m enable efficient water delivery even at significant heights.
• Durable Construction: The pump casing is made of stainless steel (grade 304 – 1.4301), ensuring corrosion resistance and extended service life even under harsh operating conditions. Impellers are made from stainless steel (grade 304 – 1.4307), further increasing durability.
• Wide Temperature Range: The pump operates in ambient temperatures from -15°C to +50°C and can handle conveyed fluids from -30°C to +120°C (depending on seal version).
• Safety: IP55 protection rating ensures resistance to dust and water jets, enabling safe operation in diverse environmental conditions.
• Easy Maintenance: The pump design facilitates straightforward servicing, resulting in minimal operational costs.
• IE3 Efficiency Motor: The IE3 energy efficiency class motor reduces electrical consumption and lowers operating costs. Rated motor output: 1.1 kW at supply voltage 230-400V and frequency 50 Hz.
• Standardized Connections: Both inlet and outlet connections (ISO 228-1) have a nominal diameter of 1 inch (25 mm) with cylindrical internal gas thread (BSPP-G), simplifying integration into existing hydraulic systems.

The Wilo-Helix V is a robust and high-performance pump ideal for demanding water supply and pressure boosting applications – delivering reliable performance for professional installers and end-users seeking a dependable solution.
