Wilo-Helix V 211-1/25/E/KS/400-50 high-pressure water pump 4161716

High-pressure water pump Wilo-Helix V 211-1/25/E/KS/400-50

This is a multi-stage, vertical centrifugal pump designed for water supply, pressure boosting, and industrial applications. The pump's design allows for efficient pumping of water, even with solids up to 10 mm in diameter. Made of high-quality stainless steel, it ensures reliability and long life in demanding conditions. This model is characterized by high efficiency and the ability to adapt to specific installation needs.

Construction and application

The Wilo-Helix V pump is designed for versatility. It will work in irrigation systems, car washes, fire protection installations, as well as in water treatment and cooling liquid circulation processes. The Inline design simplifies installation and integration with existing infrastructure. The pump body optimized for flow minimizes energy losses and ensures stable operation. A solid coupling cover increases durability and facilitates maintenance.

Key features and benefits

• High performance: The maximum pump capacity is 4 m³/h, and the maximum head is 80.7 m – ideal parameters for various applications.
• Durability and corrosion resistance: Construction from high-grade stainless steel (1.4301 and 1.4307) guarantees corrosion resistance and long-term operation, even with water of varying chemical quality.
• Wide temperature range: The pump can operate in a temperature range from -30°C to +120°C (depending on the seal version), making it suitable for use in various environmental conditions.
• Safety: IP55 protection class provides protection against dust and water jets, increasing safety in harsh industrial conditions.
• Energy efficiency: IE3 energy efficiency class motor minimizes electricity consumption, reducing operating costs.
• Easy maintenance: The pump design is designed for easy access to components requiring regular inspection or replacement.
• Adaptability: Various material versions are available (including a version for aggressive media with FKM sealing) and options to adapt to specific installation requirements (e.g., motor protection, IE4 efficiency class).
• Application in fire protection systems: Possibility of using Helix V pumps in fire protection systems (version with VdS certificate).

The pump is adapted to operate with a voltage of 230-400V at a frequency of 50Hz and has flanged connections DN25 compliant with EN 1092-1 standards of pressure class PN25. The motor output power is 1.1 kW with a rated current of 2.5A.
