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.
