Wilo-Helix V 409-1/25/E/KS/400-50 high-pressure water pump 4160527

High-pressure water pump Wilo-Helix V 409-1/25/E/KS/400-50

This Wilo-Helix V multistage, vertical centrifugal pump is a robust solution for water supply, pressure boosting, and industrial applications. Its inline design and high hydraulic efficiency make it an efficient choice for both installers and end-users. The pump is designed to operate with clean water but can also be used with liquids containing small impurities.

Characteristics and application

Wilo-Helix V 409-1/25/E/KS/400-50 finds wide application in systems: water supply and pressure boosting, circulation installations, fire protection systems, car washes, and irrigation. Thanks to its construction from corrosion-resistant materials, the pump is durable and reliable even in harsh conditions. Made of high-quality stainless steel (depending on the version – 1.4301 or 1.4404), it ensures long-term operation without frequent repairs. The possibility of use in aggressive media (FKM version) expands its range of applications.

Advantages and benefits

• High efficiency: The maximum pump capacity is 6.5 m³/h, and the maximum head is 70.67 m, allowing for efficient water pumping to significant heights.
• Durable construction: The pump body made of stainless steel (grade 304 or 316) provides corrosion resistance and long life.
• Versatility: Can be used with various types of liquids, including potable water (EPDM version) and aggressive media (FKM version).
• Reliability: Solid construction and high-quality materials guarantee trouble-free operation for a long time.
• Easy maintenance: The pump design is designed for easy access to components requiring servicing.
• IE3 motor: The use of an IE3 energy efficiency class motor translates into lower electricity consumption and reduced operating costs.
• Wide temperature range: The pump can operate at an ambient temperature from -15°C to +50°C and pump liquids with a temperature from -30°C to +120°C (depending on the gasket version).
• Safety: The IP55 protection class provides protection against dust and water jets, increasing safety in various environmental conditions.

The Wilo-Helix V pump is powered by a voltage of 230-400V at a frequency of 50Hz and draws a rated current of 2.5A, with a motor output of 1.1 kW. Inlet and outlet connections with a nominal diameter of DN 25 terminated with flanges (PN 25) ensure easy installation in existing installations.
