MAINTENANCE AND REPAIR OF THE WEARING PARTS OF THE PUMP WILL MAINTAIN PEAK
OPERATING PERFORMANCE.
STANDARD PERFORMANCE FOR PUMP MODELS 13D1−19
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. The maximum continuous
operating speed for this pump is 3600
RPM.
