Wilo-Helix V 1012-1/16/E/KS/400-50 high-pressure water pump 4150558

High-pressure water pump Wilo-Helix V 1012-1/16/E/KS/400-50 – a reliable solution for water supply and pressure boosting.

This multistage vertical centrifugal pump with inline ports is a robust choice for both professional installers and end users. Designed for efficient pressure boosting in water supply systems, industrial circulation circuits, as well as fire protection and car wash systems. The Wilo-Helix V pump design ensures reliability and long service life, even under demanding conditions.

Construction and materials ensuring durability

The pump casing is made of stainless steel (grade 304 or 316L depending on the model), while the impeller and guide vanes are constructed from corrosion-resistant materials, providing high resistance to water and other media. This makes the pump ideal for applications requiring contact with various liquids. The use of a laser-welded 2D/3D hydraulic design optimizes efficiency and minimizes the risk of cavitation. High manufacturing quality translates into minimal maintenance requirements and long-term trouble-free operation.

Performance and technical specifications

The Wilo-Helix V 1012-1/16/E/KS/400-50 pump offers a maximum flow rate of up to 15.4 m³/h and a maximum head of up to 126.1 m, with a motor power of 5.5 kW. It operates at 400 V voltage and 50 Hz frequency. The IP55 protection rating ensures protection against dust and water jets, enabling installation in diverse environments. The pump features inlet and outlet flanges with a nominal diameter of 1 1/2 inches (40 mm), compliant with ISO 228-1 standard and pressure class PN 16. The motor efficiency class is IE3, resulting in lower operating costs.

The pump is designed to operate in ambient temperatures ranging from -15°C to +50°C and can handle fluid temperatures from -30°C to +120°C (depending on the EPDM version).
