P.025 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.
