Wilo-Helix V 233-1/25/E/KS/400-50 high-pressure water pump 4161734

High-pressure water pump Wilo-Helix V 233-1/25/E/KS/400-50

This multistage, vertical centrifugal pump from the Wilo-Helix V series is designed for demanding applications in water supply, pressure boosting, and industrial installations. It is characterized by high efficiency and reliability, and its construction ensures long-lasting and trouble-free operation. The pump is particularly well suited for use with clean water, but can also be used in systems with process water.

Construction and application

The Wilo-Helix V 233-1/25/E/KS/400-50 pump features a robust construction, with a casing and impeller made of stainless steel (1.4301 and 1.4307 respectively), which guarantees corrosion resistance and long service life. Equipped with a 3 kW motor and a supply voltage of 400 V (50 Hz), it provides a flow rate of up to 4 m³/h with a maximum head of 242.8 m. The inline design simplifies installation in the pipeline, and the connection flanges (DN 25) ensure a tight connection.

The pump is used in:

• Water supply and pressure boosting
• Industrial installations (circulating, process water)
• Fire protection systems
• Car washes
• Irrigation
• Closed cooling circuits

Advantages and characteristic features

• High efficiency: Thanks to hydraulic optimization, the pump is characterized by a high efficiency ratio (MEI = 0.7).
• Corrosion resistance: The use of stainless steel in the impeller and casing construction provides long-term protection against corrosion, even in harsh working conditions.
• Robust construction: The durable housing and precise workmanship guarantee the reliability and long service life of the device.
• Wide temperature range: The pump can operate in an ambient temperature from -15°C to +50°C and pump liquid with a temperature from -30°C to +120°C.
• High working pressure: The maximum working pressure is 25 bar, allowing the pump to be used in systems requiring high pressure.
• Protection class IP55: Provides protection against water jets and dust, allowing the pump to be installed in various environments.
• IE3 class motor: The use of a motor with a high energy efficiency class (IE3) translates into lower electricity consumption.
• Installation length: 250 mm allows for easy integration with existing installations.

The Wilo-Helix V pump is an investment in a reliable and efficient solution for demanding water applications. Its robust construction and high quality workmanship guarantee long-lasting and trouble-free operation for both professional installers and end users.
