Wilo-Helix V 616-1/16/E/KS/400-50 high-pressure water pump 4156054

High-pressure water pump Wilo-Helix V 616-1/16/E/KS/400-50

This is a multi-stage, vertical centrifugal pump designed for water supply, pressure boosting, and industrial applications. The inline design with flanged connections allows for easy installation in the system. Made of high-quality stainless steel, it ensures durability and corrosion resistance, which is particularly important in demanding operating conditions. The pump is characterized by high efficiency and reliability, and its solid construction guarantees a long service life.

Characteristics and application

The Wilo-Helix V 616-1/16/E/KS/400-50 pump is perfect for installations requiring high pressure and performance. It finds application in:

• Water supply and pressure boosting in residential and industrial buildings.
• Irrigation and car wash systems.
• Fire protection installations.
• Cooling circuits and process water systems.
• Industrial circulation installations.

Thanks to the use of corrosion-resistant materials, the pump can operate with water of varying degrees of purity, containing solid particles up to 10 mm in diameter. The pump design has been optimized in terms of flow and anti-cavitation margin, which translates into efficient operation and minimization of the risk of cavitation.

Construction and key features

The pump is equipped with a 4 kW motor powered by 400 V and 50 Hz. The motor's C characteristic allows it to react more slowly to short current surges, making it well-suited for starting devices with a motor. The impellers, guide vanes, and stage casings are made of stainless steel (grade 1.4404 / AISI 316L), which ensures corrosion resistance and long-term operation. The pump body is made of stainless steel (grade 1.4301 / AISI 304L). The IP55 protection class guarantees protection against dust and water jets, allowing the pump to be mounted in various environmental conditions. The pump length is 204 mm, and the maximum operating pressure is 16 bar. The motor's energy efficiency class is IE3 – which means higher energy efficiency than standard motors. The maximum pump capacity is 10 m³/h with a maximum head of 141.6 m. The inlet and outlet connections are internal gas tapered threads BSPP-G (ISO 228-1) with a nominal diameter of 1 ¼ inch (32 mm).
