Wilo-Helix V 203-1/16/E/KS/400-50 high-pressure water pump 4161705

High-pressure water pump Wilo-Helix V 203-1/16/E/KS/400-50

This is a multi-stage, vertical centrifugal pump designed for efficient water pressure boosting in various applications. Made of high-quality stainless steel, it is characterized by durability and corrosion resistance. This model is particularly well suited for working with contaminated water, thanks to the ability to pump liquids with solids up to 10 mm in diameter. The pump is intended for installation in water supply systems, irrigation, car washes, and fire protection installations.

Design and application

The Wilo-Helix V 203-1/16/E/KS/400-50 pump is a normally suctioned device with an Inline design, which facilitates integration with existing installations. The pump body made of stainless steel 304 (1.4301) and the impeller made of stainless steel 304 (1.4307) ensure reliability and long life even in harsh working conditions. Thanks to the optimization of flow and the excess NPSH value, the pump operates quietly and efficiently. It can be used in circulation systems, process water and closed cooling circuits.

Key features and benefits

• High efficiency: The maximum pump capacity is 4 m³/h, and the maximum head is 21.78 m, which allows for efficient water supply even at high altitudes or to extensive installations.
• Durability and corrosion resistance: The use of stainless steel in the construction of the body and impeller guarantees long-term operation without the risk of corrosion, even in water with increased mineral or chemical content.
• Versatility of application: The pump works perfectly both in domestic installations (water supply, pressure boosting) and industrial (fire protection systems, irrigation).
• Easy maintenance: A solid coupling cover facilitates access to elements requiring servicing, which translates into minimal downtime and low operating costs.
• Safety: Protection class IP55 provides protection against dust and water jets, which increases safety in various environmental conditions.
• Energy efficiency: IE2 class motor minimizes electricity consumption, reducing operating costs.
• Wide temperature range: The pump can operate in a temperature range from -30°C to +120°C (depending on the seal version), which allows it to be used in various climatic and process conditions.
• Connections compliant with standards: BSPP-G (ISO 228-1) threaded connections and PN 16 flanges ensure easy integration with existing hydraulic installations.

The Wilo-Helix V pump is a solid solution for demanding users looking for a reliable device for boosting water pressure. Its design and materials guarantee long-term operation and minimal operating costs.
