Wilo-Helix V 424-1/25/E/KS/400-50 high-pressure water pump 4160545
High-pressure water pump Wilo-Helix V 424-1/25/E/KS/400-50
This is a multi-stage, vertical centrifugal pump designed for demanding applications such as water supply, pressure boosting, and fire protection systems. The pump's design, optimized for flow and anti-cavitation margin, ensures high efficiency and reliability. Made of durable materials, including stainless steel, it guarantees a long service life even in harsh working conditions.
Construction and application
The Wilo-Helix V 424-1/25/E/KS/400-50 pump finds wide application in various installations:
- Water supply and pressure boosting.
- Industrial circulation installations.
- Process water systems.
- Closed cooling circuits.
- Fire protection systems.
- Car washes and irrigation.
The pump design allows for normal suction and is characterized by high efficiency. Inline connections facilitate installation in existing systems. A robust coupling cover provides easy maintenance and access to serviceable components.
Materials and operating parameters
The pump housing is made of stainless steel 304 (1.4301), and the impeller of stainless steel 304 (1.4307), ensuring corrosion resistance and long-term operation. The pump operates at a voltage of 230-400V at a frequency of 50Hz and has a 3 kW motor with energy efficiency class IE3. The maximum head is 190 meters, and the maximum flow rate is 6.5 m³/h at a maximum working pressure of 25 bar. The temperature range of the pumped liquid is from -30°C to +120°C, and the ambient operating temperature is between -15°C and +50°C. The IP55 protection class guarantees protection against dust and water jets. The motor insulation class is F.
It is worth noting the Minimum Efficiency Index (MEI) of 0.7, which demonstrates the energy efficiency of the device – important for both operating costs and the environment. The pump has EN 1092-1 flanged connections with a nominal diameter of DN 25 on the inlet and outlet sides, and flanges with a pressure class of PN 25 on both sides.
