• These curves are theoretical; actual results may vary depending on installation conditions and other variables. Use these values for reference only.

• The above pressure drop charts are based upon 1/8" perforated screens and baskets handling clean water at 60 °F during ideal inlet and outlet conditions. Therefore, they should only be used for estimation purposes.

• For fluids other than water, multiply the pressure drop (Δ P) obtained from the charts by the specific gravity of the fluid in question.

• For mesh lined screens, multiply the pressure drop (Δ P) obtained from the charts by the corresponding correction factor shown in the Cv correction table.
