P8 METAL SUCTION-
LIFT CAPABILITY 

 

 

Suction-lift curves are calibrated for 
pumps operating at 305 m (1,000') above 

sea level. This chart is meant to be a 
guide only. There are many variables 

that can affect your pump's operating 

characteristics. The number of intake and 
discharge elbows, viscosity of pumping 

fluid, elevation (atmospheric pressure) 
and pipe friction loss all affect the 

amount of suction lift your pump will 
attain.
