STANDARD PERFORMANCE FOR PUMP MODEL 66B2−B
Based on 70_ F (21_ C) clear water at sea level

are seldom identical, your performance may be dif-
ferent due to such factors as viscosity, specific
gravity, elevation, temperature, and impeller trim.
Pump speed and operating condition
points must be within the continuous per-
formance range shown on the curve.
