A large wine producer in New Zealand was struggling to overcome continuous pump clogging problems in their main wastewater sump due to heavy loading of leaves, bottle caps, string, plastic caps and strapping. The original pumps that were installed for the job simply could not cope and as a result, a screen had to be installed on the suction to filter out suspended solids. Screening the waste only caused more problems, as solids would simply become "blanketed" over the screen, restricting pump flow. By installing a Vaughan chopper pump, any previous clogging risk was instantly eliminated meaning that the suction screen could be removed.
