Wilo-Helix V 429-1/25/E/KS/400-50 high-pressure water pump 4160547

High-pressure water pump Wilo-Helix V 429-1/25/E/KS/400-50

This multistage, vertical centrifugal pump from Wilo is a reliable solution for water supply, pressure boosting, and industrial applications. The pump's design has been optimized for efficient flow and minimization of cavitation, resulting in a long service life and stable operation. It is ideally suited for both domestic and more demanding industrial systems.

Construction and application

The Wilo-Helix V pump is designed for pumping clean water or non-aggressive liquids with a temperature of up to 120°C (depending on the seal version). It is suitable for irrigation systems, car washes, fire protection installations, as well as water treatment and cooling water circulation processes. Thanks to its solid construction with corrosion-resistant materials, the pump is durable and reliable even in harsh working conditions. The EPDM version is approved for use with potable water.

Key features and benefits

• High efficiency: The pump's maximum flow rate is 6.5 m³/h, and the maximum head is 231.7 m – this allows for efficient operation in a wide range of applications.
• Solid construction: The pump housing is made of stainless steel (grade 304 or 316L depending on the model), providing corrosion resistance and long service life. Impellers and diffusers are also made of stainless steel (grade 304 or 316L).
• Energy-efficient motor: The motor with energy efficiency class IE3 and a power of 4 kW minimizes electricity consumption.
• Durable materials: The shaft made of stainless steel (1.4301 or 1.4462) ensures reliability and resistance to mechanical loads.
• Easy maintenance: The pump design is designed for easy access to components requiring servicing.
• Wide temperature range: The pump can operate in an ambient temperature from -15°C to +50°C and pump liquids with a temperature from -30°C to +120°C (depending on the seal version).
• Safety: The IP55 degree of protection guarantees protection against dust and water jets.
• Flanged connections: Both the inlet and outlet connections are DN25 flanges compliant with EN 1092-1, which facilitates integration with existing installations.

The pump has a motor thermal protection and is designed for continuous operation. The use of high-quality materials guarantees reliable operation for a long time, minimizing operating costs and downtime. Thanks to precise workmanship and hydraulic optimization, the pump is characterized by high energy efficiency and quiet operation.
