Wilo-Helix V 1004-1/16/E/KS/400-50 high-pressure water pump 4150543

High-pressure water pump Wilo-Helix V 1004-1/16/E/KS/400-50

This three-phase vertical centrifugal pump Wilo-Helix V is a robust solution for water supply and pressure boosting in installations. Designed for demanding operating conditions, it delivers high performance and reliability. The pump is particularly well-suited for systems requiring stable pressure and efficient water transport.

Construction and application

The Wilo-Helix V 1004-1/16/E/KS/400-50 features a corrosion-resistant construction — the pump casing and impeller are made of stainless steel (304 and 304L), ensuring long service life even when pumping liquids with varying chemical compositions. The pump is suitable for:

• Domestic and potable water supply,
• Irrigation systems,
• Industrial water installations,
• Pressure boosting in existing systems.

Thanks to its compact dimensions (height 149 mm, installation length 248 mm) and flanged connections (nominal diameter 1 1/2 inch), installation is relatively straightforward, even in confined spaces. The IP55 protection rating ensures resistance to dust and water jets, enabling operation in diverse environmental conditions.

Performance and operating parameters

The Wilo-Helix V 1004-1/16/E/KS/400-50 achieves a maximum flow rate of 15.4 m³/h and a maximum head of 42.38 m. The 1.5 kW motor with IE3 energy efficiency class ensures optimal energy consumption. Operation at voltages of 230-400V and frequency 50 Hz ensures compatibility with most standard electrical installations. The maximum working pressure is 16 bar, guaranteeing safe operation in systems with elevated pressure requirements. The C characteristic allows slower response to current surges, making it well-suited for starting motor-driven equipment. The minimum efficiency index (MEI) of 0.7 confirms the pump’s high energy efficiency — resulting in lower operating costs.
