STANDARD PERFORMANCE FOR PUMP MODELS 11 1/2A2-E2 1P AND 11 1/2A2-E2 3P
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.
Pump speed and operating condition
points must be within the continuous per
formance range shown on the curve.
