Wilo-Helix V 1015-1/25/E/KS/400-50 high-pressure water pump 4150563

High-pressure water pump Wilo-Helix V 1015-1/25/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 working conditions. The pump is characterized by high efficiency and reliability, and its solid construction guarantees a long service life.

Performance and application

Wilo-Helix V 1015-1/25/E/KS/400-50 is a versatile device used in:

• Water supply and pressure boosting in buildings and installations.
• Industrial circulation installations, providing a stable medium flow.
• Irrigation systems, car washes, and fire protection systems – where high performance and reliability are required.
• Cooling circuits, where efficient fluid circulation is key.
• Working with potable water (in stainless steel versions in contact with the medium).

The pump achieves a maximum flow rate of 16 m³/h and a maximum head of 158.9 m, allowing for efficient water pumping even to significant heights. The motor power is 5.5 kW at a supply voltage of 400 V and a frequency of 50 Hz.

Construction and materials

Key components of the pump are made of high-quality corrosion-resistant materials:

• Pump housing made of stainless steel (grade 304 or 316 depending on the version), ensuring durability and resistance to aggressive media.
• Impellers, diffusers, and stage casings also made of stainless steel (grade 304 or 316), guaranteeing long-term trouble-free operation.
• Shaft made of stainless steel (grade 1.4301 or 1.4462), providing stability and mechanical strength.
• Connections made of stainless steel, compatible with EN 1092-1 standards (nominal diameter DN40).

The degree of protection IP55 provides protection against dust and water jets, allowing the pump to operate in various environmental conditions. Insulation class F guarantees safe use. The embedding length is 280 mm and the pump height is 149 mm. The maximum operating pressure is 25 bar.
