High-pressure water pump Wilo-Helix V 204-1/16/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. Model 204-1/16/E/KS/400-50 is particularly recommended where reliability and high performance are required.

Design and application

The Wilo-Helix V pump is designed for easy maintenance and long-term operation. The pump body optimized for flow minimizes hydraulic losses, and a solid coupling cover provides additional protection. It finds application in:

• Water supply and pressure boosting.
• Industrial installations, including circulation systems.
• Process water systems and closed cooling circuits.
• Fire protection systems.
• Car washes and irrigation systems.

Key features and benefits

• Material durability: The pump body made of stainless steel 304 (1.4301) and the impeller made of stainless steel 304 (1.4307) guarantee corrosion resistance and long pump life, even in harsh working conditions.
• High efficiency: The maximum head reaches 28.78 m with a maximum flow rate of 4 m³/h, allowing for effective satisfaction of even demanding installations.
• Safety: Insulation class F and protection degree IP55 ensure safe pump operation in various environments.
• Versatility: Possibility of use with potable water (EPDM version) increases the range of pump applications.
• Reliability: Solid construction and precise workmanship guarantee reliable operation for a long time.
• Energy efficiency: IE2 class motor minimizes electricity consumption, resulting in lower operating costs.
• Easy installation: Compact inline design facilitates integration of the pump with the existing hydraulic installation.

The pump operates with a voltage of 400 V and a frequency of 50 Hz, and its rated current is 0.95 A with a motor power of 0.37 kW. The temperature range of the pumped liquid is from -30°C to +120°C (depending on the gasket version). The connections on the inlet and outlet sides are internal gas tapered BSPP-G (ISO 228-1) with a nominal diameter of 1 inch (25 mm). The maximum operating pressure is 16 bar (pressure class PN 16).
