Housing Differential Pressure vs. Liquid Flow Rate

For liquids other than water, multiply differential pressure by specific gravity.

¹Registered trademark of Tri-Clover, Inc.
²Registered trademark of DuPont Dow Elastomers.
³Dependent upon cartridge selection, fluid viscosity, and allowable pressure drop. See graph below for housing pressure drop at various flow rates. Refer to cartridge nomograph to determine initial pressure drop due to the filter cartridge. The 28MEGA+ may be used to provide longer cartridge life and lower initial pressure drop. A flow rate in excess of 100 gpm (379 lpm) is not recommended with 2" connections. Consult factory for higher flow rates.
