Wilo-Helix V 1003-1/16/E/KS/400-50 high-pressure water pump 4150542

High-pressure water pump Wilo-Helix V 1003-1/16/E/KS/400-50

This is a three-phase, vertical centrifugal pump designed for water supply and pressure boosting in industrial, process, and closed-loop cooling systems. It is also suitable for car washes, fire protection systems, and irrigation installations. The pump's design has been optimized for efficiency and durability, resulting in reliable operation and low operating costs.

Construction and application

The Wilo-Helix V pump is characterized by a compact design and ease of maintenance. The connection between the pump shaft and the motor shaft is made using a clamping sleeve, compliant with IEC standards. A separate lantern roller bearing ensures optimal acceptance of axial forces, and a corrosion-resistant shaft with a stainless steel sleeve guarantees a long service life. The pump housing, made of stainless steel, is optimized for flow and net positive suction head (NPSH) value. This makes the pump resistant to corrosion and ensures stable operation even in harsh conditions.

• High efficiency: Laser-welded 2D/3D hydraulics with flow and degassing mode optimization translates to lower energy consumption.
• Durability: Impellers, guide vanes, and stage casings made of stainless steel provide corrosion resistance and long device life.
• Easy maintenance: Construction with a solid coupling cover and a sealing cassette facilitate access to elements requiring servicing.
• Versatility: Can be used with potable water (in versions with stainless steel in contact with the medium).
• Safety: The pump is designed to operate in a temperature range from -30°C to +120°C and a maximum operating pressure of 16 bar.

Technical and design parameters

The pump is equipped with a 1.1 kW motor with energy efficiency class IE3, ensuring high performance with low power consumption. The motor speed is 2900 rpm, and the rated current is 2.5 A. Flange connections with a diameter of 40 mm (1 1/2 inch) allow for easy connection to the installation. The IP55 protection class guarantees protection against dust and water jets, enabling pump installation in various working environments. Insulation class F provides high thermal resistance of the motor. It is worth noting the Minimum Efficiency Index (MEI) of 0.7, which confirms the high energy efficiency of the device. Materials used in production – stainless steel 304 (pump body) and stainless steel 304 (impeller) – guarantee corrosion resistance and long-term reliability of the pump even in an aggressive chemical environment.
