Wilo-Helix V 220-1/25/E/KS/400-50 high-pressure water pump 4161728

High-pressure water pump Wilo-Helix V 220-1/25/E/KS/400-50

This three-phase, vertical centrifugal pump Wilo-Helix V is a robust solution for water supply, pressure boosting, and industrial applications. The flow-optimized and efficient design, combined with corrosion-resistant materials, guarantees reliable operation in demanding conditions. The pump is particularly well-suited for use with potable water, thanks to versions with stainless steel parts in contact with the medium (EPDM version).

Design and application

The Wilo-Helix V pump features an Inline design, which simplifies installation in existing systems. It finds application in:

• Water supply and pressure boosting.
• Circulation installations in industry.
• Process water systems.
• Closed cooling circuits.
• Fire protection systems.
• Car washes and irrigation systems.

Durable materials, such as stainless steel 304 (1.4301) and 304 (1.4307) used to make the pump body and impeller, ensure long life and corrosion resistance. A robust coupling cover facilitates device maintenance.

Key features and benefits

• High efficiency: The maximum pump capacity is 4 m³/h, and the maximum head is 148 m, allowing for efficient water pumping even at significant heights.
• Durability and reliability: The pump body made of stainless steel 304 (1.4301) and the impeller made of stainless steel 304 (1.4307) ensure corrosion resistance and long device life.
• Wide temperature range: The pump can operate in a temperature range from -30°C to +120°C, making it a versatile solution for various applications.
• Safety: Protection class IP55 protects the pump against dust and water jets, ensuring safe operation in various environmental conditions.
• Energy efficiency: The IE3 class motor provides high energy efficiency, which translates into lower operating costs.
• Easy maintenance: The pump design has been designed for easy maintenance and access to key components.
• Resistance to aggressive media: Versions with FKM seals are available for working with aggressive media (up to +90°C).

The pump is designed to operate at 230-400V with a frequency of 50Hz and has EN 1092-1 DN25 flange connections with a pressure class of PN25. The use of flange connections facilitates the integration of the pump with existing hydraulic infrastructure.
