Wilo-Helix V 202-1/16/E/KS/400-50 high-pressure water pump 4161704

High-pressure water pump Wilo-Helix V 202-1/16/E/KS/400-50

This is a vertical, multi-stage centrifugal pump designed for efficient pressure boosting and water supply. The inline design with flanged connections simplifies installation in the system. Made of high-quality stainless steel, it ensures reliability and long life, even in harsh working conditions. This pump is used both in industrial installations and in domestic water supply systems.

Construction and application

The Wilo-Helix V pump is designed for a wide range of applications. It will be useful in irrigation systems, car washes, fire protection installations, as well as in water treatment and liquid circulation processes. The pump body optimized for flow minimizes energy losses and ensures high efficiency. A solid coupling cover facilitates maintenance and increases the durability of the device. The possibility of using it with potable water (EPDM version) confirms its versatility.

• Water supply and pressure boosting: Ideal for residential, commercial and industrial buildings.
• Circulation installations: Provides efficient circulation of liquids in heating and cooling systems.
• Process water: Works well in industrial applications requiring precise liquid dosing.
• Fire protection systems: Provides reliable water supply in emergency situations.
• Car washes and irrigation: Delivers the appropriate water pressure to car washes and irrigation systems.

Technical characteristics and benefits

The pump is equipped with a 0.37 kW motor powered by 400 V voltage and 50 Hz frequency. Impellers, guide vanes and stage casings are made of stainless steel (1.4307 or 1.4404), which guarantees corrosion resistance and long-term operation. The maximum pump capacity is 4 m³/h, and the maximum head is 14.66 m, allowing it to be adapted to various hydraulic needs. The energy efficiency class of the motor is IE2 – this means energy savings during operation. The IP55 protection class protects the pump from dust and water jets, allowing it to operate in various environmental conditions.

• High efficiency: Optimized hydraulic design minimizes energy losses and reduces operating costs.
• Durability: Made of high-quality stainless steel, it ensures corrosion resistance and long life of the device – the material of the housing is stainless steel 304 (1.4301).
• Versatility: Possibility of use with various types of liquids, including potable water (EPDM version).
• Easy maintenance: User-friendly design facilitates access to elements requiring regular inspection and replacement – a solid coupling cover is an additional advantage for the service technician!
• Safety: IP55 protection class provides protection against dust and water, increasing safety of use.
• Reliability: The motor with energy efficiency class IE2 guarantees stable operation of the device for a long time – the motor power is 0.37 kW and the rotational speed is 2900 1/min .

The pump has internal gas tapered BSPP-G connections with a diameter of 1 inch (25 mm) on both the inlet and outlet sides, as well as a maximum operating pressure of 16 bar (PN 16 class). The mounting length is 204 mm and the ambient temperature range is -15 to +50 °C .
