Operators also noticed that the pump was occasionally noisy." I would appear that the pump is cavitating at low sump levels (question 1) resulting from insufficient NSPHa and this was also the problem with the premature seal failure (question 2) when operating at low sump levels. - Ian Simpson Wed, 26 Aug 2009 20:17:48 +0100 http://www.pump-zone.com/pumps/centrifugal-pumps/pump-challenge-2-moving-a-pump-from-the-bottom-of-a-dry-pit.html#comment-127 this is an interesting article, thank you! - anonymous Fri, 24 Jul 2009 10:25:23 +0100
