PUMP MAINTENANCE AND REPAIR - SECTION E

MAINTENANCE AND REPAIR OF THE WEARING PARTS OF THE PUMP WILL MAINTAIN PEAK
OPERATING PERFORMANCE.

STANDARD PERFORMANCE FOR PUMP MODEL 14C2‐F3L

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 part
numbers.

Pump speed and operating condition
points must be within the continuous per
formance range shown on the curve.
