High-pressure water pump Wilo-Helix V 620-1/25/E/KS/400-50

This multistage vertical centrifugal pump Wilo-Helix V 620 is a robust solution for water supply and pressure boosting in installations. Constructed from high-quality stainless steel, it ensures reliable operation and long service life, even under demanding conditions. The pump is particularly recommended where high flow rates and significant lift heights are required.

Design and application

The Wilo-Helix V 620 features a compact design with inline ports, simplifying installation and integration into existing systems. It utilizes a laser-welded 2D/3D hydraulic system that optimizes efficiency and minimizes the risk of air bubble formation in the pumped medium. Thanks to corrosion-resistant materials, the pump can handle fluids with temperatures ranging from -30°C to +120°C. It is an ideal solution for water supply systems, irrigation, and industrial applications.

Performance and operating parameters

The Wilo-Helix V 620 offers a maximum flow rate of up to 10 m³/h and a maximum head of 176.2 m. The 4 kW motor is powered by 400 V at 50 Hz. The IP55 protection rating ensures resistance to dust and water jets, enabling installation in diverse environments. The motor efficiency class IE3 guarantees energy savings during operation. Maximum working pressure is 25 bar. The C characteristic allows smooth starting of motor-driven equipment by responding slowly to brief current surges.
