Wilo-Helix V 209-1/25/E/KS/400-50 high-pressure water pump 4161712

High-pressure water pump Wilo-Helix V 209-1/25/E/KS/400-50

This is a high-performance, multi-stage centrifugal pump designed for water supply, pressure boosting, and industrial applications. The pump's design, optimized for flow and net positive suction head, ensures reliable operation in demanding conditions. Made of high-quality stainless steel, it guarantees durability and corrosion resistance. This model is particularly recommended for installations requiring high pressure and performance.

Characteristics and application

The Wilo-Helix V 209-1/25/E/KS/400-50 pump has a wide range of applications in various systems:

• Water supply and pressure boosting in residential and industrial buildings.
• Circulation installations in industry.
• Fire protection systems – thanks to the ability to adapt to specific conditions (e.g. VdS certificate).
• Car washes and irrigation systems.
• Cooling circuits.
• Water treatment – pumping contaminated water with solids up to 10 mm in diameter.

The pump design also allows operation with aggressive media (in the version with FKM seal).

Construction and design features

The pump is characterized by a solid construction and thoughtful design:

• Pump casing: Made of stainless steel 304 (1.4301) or 316L (1.4404) – provides corrosion resistance and long life.
• Impeller and diffusers: Made of stainless steel 1.4307 or 1.4404, guaranteeing high hydraulic efficiency and abrasion resistance.
• Connections: Flanged (DN 25) in accordance with EN 1092-1 standards, pressure class PN 25, allow easy installation and integration with existing installations.
• Motor: Three-phase with a power of 0.75 kW, powered by a voltage of 230…400 V and a frequency of 50 Hz, characterized by energy efficiency class IE3.
• Degree of protection: IP55 – provides protection against dust and water jets, allowing installation in various working environments.
• Pump length: 250 mm - facilitates integration of the pump with existing hydraulic infrastructure.

The pump also has a solid coupling guard to facilitate maintenance and is adapted to operate at an ambient temperature of -15°C to +50°C (with the possibility of extending the range). The maximum liquid temperature is +120°C (depending on the seal version).

It is also worth mentioning the laser-welded 2D/3D hydraulic systems, which optimize pump efficiency and ensure proper degassing and liquid flow.
