Static Suction Lift
Static Suction Lift : In hydraulics, the term used for the vertical distance between the surface of the water supply to the suction inlet of a fire pump; may be positive or negative. Positive suction lift occurs when the water supply level is higher than that of the suction inlet (the water is aiding the pump). If the fire pump is above the water supply it must lift the water, creating a negative suction lift (the most common situation)
