GEA Hilge CONTRA III multistage centrifugal pump

GEA’s Hilge CONTRA III multistage centrifugal pump is designed according to hygienic design guidelines, has electro-polished surfaces and high-quality sealing materials, and is suitable for use in dairy, beverage and food industries, in addition to pharmaceutical ones. Its increased drive power, over the smaller models, means its maximum flow rate is 100 m³/h.

The pump’s components are forged, deep-drawn and milled from 316L grade stainless steel and are designed to be hygienic and easy to maintain. Clean-in-place and sanitising cycle times can be reduced, leading to savings in water, cleaning agents and energy. Sterilisation-in-place pumps are also available, and the pump is able to remain in the pipeline for a motor change. Pipes are easy to clean, with a cavitation-free design, with a surface roughness from Ra ≤0.8 µm to Ra ≤0.4 µm.

A large number of configurations are viable, with both horizontal and vertical installations possible. For corrosive atmospheres, the product is available in the Adapta variant, which has EC conformity approval according to ATEX Directive 2014/34/E.

For plants that run on weekends or under partial loads, the speed control feature means water can be kept continuously in motion regardless of the operating phase, thus reducing the chance of contamination. The pump’s frequency converters have a lower heat effect on the pumped media; less cooling is required therefore reducing energy and protecting the media.
