STANDARD PERFORMANCE FOR PUMP MODEL VG8D3-B
Based on 70_ F (21,1_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.
