Wilo-Helix V 209-1/16/E/KS/400-50 high-pressure water pump 4161711

High-pressure water pump Wilo-Helix V 209-1/16/E/KS/400-50

This is a multi-stage, vertical centrifugal pump designed for a wide range of applications, from water supply and pressure boosting to fire protection systems and industrial installations. The inline design with flanged connections allows for easy installation in existing pipelines. Made of high-quality stainless steel, it ensures reliability and durability even in harsh working conditions. The pump is characterized by high efficiency and energy efficiency (IE3 class), which translates to lower operating costs.

Construction and application

The Wilo-Helix V pump has been designed with versatility and ease of maintenance in mind. The pump housing optimized for flow minimizes hydraulic losses, and a robust coupling cover ensures durability and safety. It can be used to pump clean or slightly contaminated water with a temperature from -30°C to +120°C (depending on the seal version). Thanks to the wide range of operating parameters, it finds application in:

• Water supply and pressure boosting
• Industrial installations (water circulation)
• Fire protection systems
• Car washes
• Irrigation
• Cooling circuits

Technical characteristics and benefits

The pump is powered by a three-phase motor with a power of 0.75 kW and a supply voltage of 400 V (±10%), 50 Hz. The maximum capacity is 4 m³/h, and the maximum head is 65.63 m. Construction from corrosion-resistant materials (stainless steel 1.4301 and 1.4307) guarantees a long service life and minimizes the risk of failure. The degree of protection IP55 provides resistance to dust and water jets, allowing the pump to be installed in various environments.

• High efficiency: IE3 class motor minimizes electricity consumption.
• Durability: Construction of high-quality stainless steel ensures corrosion resistance and long service life.
• Versatility: Wide range of operating parameters allows the pump to be adapted to various applications.
• Easy installation: Inline design facilitates integration of the pump with existing pipeline installations.
• Reliability: Solid construction and precise workmanship guarantee trouble-free operation for a long time.
• Safety: IP55 protection class protects the pump from external factors.

The pump has inlet and outlet connections with a diameter of 1 inch (25 mm) with an internal cylindrical BSPP-G (ISO 228-1) gas thread. The maximum working pressure is 16 bar. The motor insulation class is F, which ensures safe operation in various temperature conditions.
