hilge: maxana


Single stage, end-suction centrifugal pump made of heavy duty, rolled Stainless steel, major dimensions and characteristics to DIN EN 733 and DIN EN 22858.

The pumps are used in the brewhouse of breweries, for beer filtration, beverage,dairy and food processing applications, as well as UF filtration systems, hot and cold water, brine, condensate and CIP fluids.

Further applications are in special systems in the chemicals and manufacturing industries, surface treatment for environmental technologies (water treatment) and the textile industry.
