SSP (Open Impeller) Performance at 3500, 2900, and 1750 rpm.

Our SSP open impeller pump is better suited for applications where solids may be present in the pumpage.  Open impeller pumps also can be adjusted for minor changes in performance.  See this article for notes on setting open impeller clearances.  Our instruction manual also has a section that discusses open impeller shimming and performance here.
