Refer to performance curves for 3450 RPM and 1150 RPM selections
Note: Units shown in the selection table are non-overloading with their motors at the stated condition point and for a reasonable drop in head. Not all selections are non-overloading throughout the entire operating range. See performance curves for additional information.
Explanation of model numbers: Example: 3SCH-25-4; 3 indicates 3 inch discharge; SCH indicates type of pump (SCL, SC, SCH are single-stage pumps of various head ranges, SSC are two-stage pumps); -25 Indicates motor horsepower; -4 indicates motor speed (-4=1750 RPM, -2=3450 RPM, -6=1150 RPM).
