Wilo-Helix V 1612-1/25/E/KS/400-50 high-pressure water pump 4141162

High-pressure water pump Wilo-Helix V 1612-1/25/E/KS/400-50

This powerful, vertical centrifugal pump is designed for water supply and pressure boosting in a wide range of applications – from industrial systems to domestic installations. The Wilo-Helix V pump design combines high efficiency, durability and ease of maintenance, making it a reliable solution for both professional installers and end users. The pump is characterized by a compact design with Inline connections, which simplifies integration with existing installations.

Design and application

The high-pressure design of the pump allows for efficient water pumping even in demanding conditions. Made of high-quality stainless steel (pump body, impeller), it provides corrosion resistance and long life. The pump is used in:

• Water supply and pressure boosting
• Circulation systems (industrial and process)
• Cooling circuits
• Fire protection systems
• Car washes
• Irrigation

Thanks to the ability to work with liquid temperatures up to 120°C (depending on the seal version), the pump also performs well in applications requiring water heating.

Key features and benefits

• High efficiency: Laser-welded 2D/3D hydraulics ensures optimal flow and minimizes energy losses.
• Durability: Made of corrosion-resistant materials (stainless steel) guarantees long pump life, even in an aggressive environment.
• Easy maintenance: The pump design allows easy access to components requiring servicing, and the demountable coupling (in models ≥ 7.5 kW) facilitates the replacement of the mechanical seal without the need to disassemble the motor.
• Versatility: A wide range of operating parameters (flow rate up to 26 m³/h, head up to 157.6 m, working pressure up to 25 bar) allows the pump to be adapted to different needs.
• Safety: The possibility of using EPDM seals allows the pump to be used in contact with potable water.
• IE3 motor: The use of an energy efficiency class IE3 motor helps to reduce operating costs.
• Solid construction: The pump body is made of stainless steel 304 (1.4301) providing strength and corrosion resistance. The impeller made of stainless steel 304 (1.4307) further increases the durability of the device.

The pump is designed for continuous operation in ambient temperatures from -15°C to 50°C and with liquid temperatures from -30°C to +120°C, ensuring its reliability in various environmental conditions. The IP55 protection class protects the device against dust and water jets, increasing its safety.
