Wilo-Helix V 616-1/25/E/KS/400-50 high-pressure water pump 4156055

High-pressure water pump Wilo-Helix V 616-1/25/E/KS/400-50

This is a multi-stage, vertical centrifugal pump designed for demanding applications where high performance and reliability are key. The inline design with round connections allows for easy installation in existing systems. The Wilo-Helix V 616-1/25/E/KS/400-50 pump is used in water supply, pressure boosting, industrial installations and fire protection systems. The robust construction and high-quality materials guarantee a long service life and minimal operating costs.

Construction and application

The pump is designed to operate with clean water or liquids with a small amount of solids (up to 10 mm in diameter). The pump body is made of stainless steel (grade 304 or 316 depending on the version) to ensure corrosion resistance and resistance to aggressive media. Impellers and diffusers are also made of stainless steel, which further increases the durability of the device. The pump is adapted to work in a wide temperature range – from -30°C to +120°C (depending on the EPDM or FKM version). The possibility of use in fire protection systems confirms its versatility and safety of use.
