STANDARD PERFORMANCE FOR PUMP MODEL 62 1/2D1--CH23 S/G
Based on 70_ F (21_ C) clear water at sea level
with minimum suction lift. Since pump installations
are seldom identical, your performance may be dif-
ferent due to such factors as viscosity, specific
gravity, elevation, temperature, and impeller trim.
If your pump serial number is followed by an “N”,
your pump is
NOT a standard production model.
Contact the Gorman-Rupp Company to verify per-
formance or part numbers.
Never tamper with the governor to gain
more power. The governor establishes
safe operating limits that should not be
exceeded.
