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 T6A60S-B, Including /F, /FM, /WW

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.
