STANDARD PERFORMANCE FOR PUMP MODEL 03B31-B
Based on 70_ F (21_ C) clear water (corrected to
.80 specific gravity) at sea level with minimum suc­
tion lift. Since pump installations are seldom identi­
cal, your performance may be different due to such
factors as viscosity, specific gravity, elevation, tem­
perature, 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.
