STANDARD PERFORMANCE FOR PUMP MODEL 81 1/4B3−E.33 1P
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.
