Sizing a pump header Pump engineering Eng-Tips

Aug 03, 2010 For the suction header: Make sure that the lengths between the header/suction pipe connection and the header/pump connections is not only as short as possible but also of the same lengths (if possible). Your suction pipe has a certain diameter which must consider the total flow of all pumps that can run in parallel in respect of fluid velocity.
