ANDRITZ Pump solutions for the starch industry www.andritz.com/pumps
ANDRITZ Pump solutions for the starch industry Decades of experience in hydraulic machine manufacturing and comprehensive process know-how form the basis of our pumps top performance. Our highquality products and in-depth knowledge of starch production processes generate reliable pumping solutions to meet the needs of our customers. ANDRITZ HYDRO offers innovative and targeted pumping solutions throughout the entire starch production process from raw material preparation to extraction and fiber separation, on to final washing and concentration. De pending on the branch of industry of the facility con cerned, we supply centrifugal pumps with a closed, open, or semi-open impeller and an integrated vacu um pump. Foaming liquids, in particular, create one of the most challenging conditions for centrifugal pumps. The combination of a single-stage cen trifugal pump with an integrated vacuum pump prevents accumulations of air at the impeller inlet and guarantees highly efficient pumping operations, even with fluids at higher viscosities (e.g. fibrous pulp slurries containing up to 40% air). The vacuum pump removes the gas content in the medium in order to ensure that fluids can be conveyed without any difficulties. As a result of these design features, self-priming centrifugal pumps from the AD series are excellently suited for trouble-free handling of crucial processes. With the company s own technical center ASTRÖ, we have an internationally recognized institute for hydraulic development and testing at our disposal. Optimization on a computer using CFD and numerous model tests are responsible for the high economic efficiency of the ACP, S, ISO, and AD pump series. Professional expertise and our understanding of customer requirements make us a valuable partner, offering development to model tests, design, manufacturing, project management and installation, to service and training all from a single source. Customers around the world trust us. They value our many years of experience throughout the value chain. The advantages at a glance Efficiencies of up to 90% Assembly system Highly cost-effective thanks to high efficiency and long service life Cost reduction if self-priming centrifugal pumps are used instead of positive displacement pumps Decades of experience and comprehensive process know-how guarantee a high standard pumps S and ACP series
