PROCESS TECHNOLOGY & COMPONENTS Contents Title Varied requirements governing pumps for the food industry Varied and challenging: the food industry, in particular, places precise demands on pumps, as they need to comply with exacting hygiene requirements and the media can often be very challenging. Comparing the WANGEN MX, Twin NG and Vario Twin NG pump ranges shows that progressing cavity pumps and twin screw pumps are ideally suited for different applications and for pumping a wide variety of media. You can read more about the wide range of applications for WANGEN pumps for different kind of media starting out on page 30.
