STANDARD PERFORMANCE FOR PUMP MODELS 62 1/2A1−GX390 S/2
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. Continuous duty perform-
ance is limited to 3600 RPM; however
the engine may be run at 3800 RPM dur-
ing intermittent fire fighting service.
