QUERY/PROBLEM(refer to the attached file) Bulk is transferred from location A to B using a centrifugal pump. At the end of operation(when there is no bulk at the pump suction), bulk remaining in the discharge line(marked by Red) causes problem for the next batch(As next batch is of different product). I need your suggestions on how to remove this remaining bulk to some satisfactory level ? P.S.: There is no facility for cleaning the line after batch operation.
