The single-stage NHK is a hygienic volute-casing pump with open impeller (for optimised pumping of shear sensitive media) rotating on a robust shaft. The thick-walled stainless steel casing is fixed by a sturdy quick-release clamp ring with sanitary grade O-ring sealing. All process-wetted parts are constructed from electro polished AISI 316L stainless steel. Importantly, the volute casing is rolled steel whilst the casing cover is forged in order to give a heavy-duty construction. All other parts are made of AISI 304. The NHK range is in accordance with food-grade standards 3A1 with a surface roughness Ra < 3,2 µm (other standards are optional). The Modular and compact design, the use of standard motors and several options guarantee a reliable performance within the food and beverage industry.
 
Applications:
Hygienic centrifugal pumps are used within the food and beverage industry such as breweries and dairies. Applications areas for these pumps include brewing (mash, wort, beer), dairying (milk, cream, fats), filtration(filtration, separation, mixing), cleaning (up and downstream CIP), filling (beer, soft drinks, juices) and sterile andpure water.
