Wilo-Helix V 222-1/25/E/KS/400-50 high-pressure water pump 4161729

High-pressure water pump Wilo-Helix V 222-1/25/E/KS/400-50

This Wilo-Helix V multistage, vertical centrifugal pump is designed for efficient water pressure boosting in various applications. It features a robust construction and high efficiency, making it a reliable solution for both professional installers and end-users. The pump is particularly well-suited for water supply systems, industrial installations, and fire protection systems.

Design and application

Wilo-Helix V is a normally suctioned pump with Inline connections, which simplifies its integration with existing installations. The pump housing is made of stainless steel (grade 304 – 1.4301) ensuring durability and corrosion resistance. Impellers and diffusers made of stainless steel (grade 304 – 1.4307) further increase resistance to aggressive media. The pump is designed to operate in ambient temperatures from -15°C to +50°C and with liquid in the range of -30°C to +120°C (depending on the seal version). This makes it suitable for a wide range of working conditions.

Performance and technical parameters

The Wilo-Helix V 222-1/25/E/KS/400-50 pump offers a maximum flow rate of up to 4 m³/h and a maximum head of up to 162.5 meters. The motor with a power of 2.2 kW is powered by a voltage of 230-400 V at a frequency of 50 Hz. The degree of protection IP55 guarantees protection against dust and water jets, allowing the pump to be installed in various environments. The energy efficiency class of the motor is IE3, which translates to lower operating costs. The maximum operating pressure is 25 bar. The motor speed is 2900 revolutions per minute, and the rated current is 4.3 A. It is worth noting the Minimum Efficiency Index (MEI) of 0.7, which indicates the high energy efficiency of the pump. The inlet and outlet connections have a nominal diameter of DN 25 and are terminated with flanges compliant with EN 1092-1 standard and pressure class PN 25.
