High-Pressure Water Pump Wilo-Helix V 411-1/16/E/KS/400-50 – Reliable Pressure Boosting

This multistage vertical centrifugal pump, Wilo-Helix V 411, is a robust solution for water supply and pressure boosting in installations. Constructed from high-quality stainless steel, it ensures long-term, trouble-free operation even under demanding conditions. The pump is particularly recommended for applications requiring high pressure, and its compact design facilitates easy installation and integration with existing systems.

Construction and Applications

The Wilo-Helix V 411 is designed for use with clean water; its impellers and casing stages are made of stainless steel, guaranteeing corrosion resistance. The pump is suitable for:

• Domestic and utility water supply systems
• Irrigation installations
• Industrial pressure boosting systems
• Residential and commercial buildings requiring stable water pressure

With a flow rate up to 6.5 m³/h and a maximum head of 87.12 meters, the pump efficiently delivers water to upper floors or remote draw-off points. The maximum operating pressure of 16 bar ensures safety and reliable performance.

Key Features and Benefits

• High Efficiency: IE3 motor energy efficiency class translates to lower operating costs. A minimum efficiency index (MEI) of 0.7 confirms optimal energy utilization.
• Durable Construction: Use of stainless steel (304 / 1.4301 and 304 / 1.4307) in the pump casing and impeller ensures corrosion resistance and extended service life.
• Compact Dimensions: Installation length of 204 mm and pump height of 128 mm enable mounting even in confined spaces.
• Wide Voltage Range: Operation from 230…400 V increases installation flexibility.
• Safety: IP55 protection rating guards against dust and water jets, allowing use in diverse environmental conditions.
• Easy Connection: Electrical connection via terminals simplifies integration with the electrical system. Inlet and outlet connections feature internal cylindrical pipe threads (BSPP-G, ISO 228-1) with a 1-inch (25 mm) diameter, ensuring compatibility with standard hydraulic components.
• Motor Designed for Continuous Operation: Operating temperature range of -30 to +120°C allows use across a broad spectrum of ambient and fluid temperatures.

The Wilo-Helix V 411-1/16/E/KS/400-50 pump is an investment in a reliable and efficient water pressure boosting solution that meets the expectations of both professional installers and end users. The 1.5 kW motor draws a rated current of 3 A at 50 Hz.
