Announcing Significant Changes to 3″ Self-Priming Centrifugal Pumps
John Blue Company is pleased to announce significant changes to the 3″ Self-Priming Centrifugal Pumps. The newly released centrifugal pump impeller has improved capacity while pressure is applied. For example, the new impeller will allow users to gain 75 GPM more flow at 30 psi compared to the standard impeller. At open flow (0 back pressure) users will realize a 20 GPM increase resulting in a maximum flow rate of 327 GPM.
