How to read the performance curves
The curves on the following pages apply to SEG pumps.
Note: The pumps are tested according to ANSI HI 11.6:2012 3B tolerance. Testing equipment and measuring
instruments are designed and calibrated according to the standards mentioned. The pumps are approved according to
tolerances for entire curves, specified in grade 3B.
