Housing Differential Pressure vs. Liquid Flow Rate
For liquids other than water, multiply differential pressure by specific gravity
1Registered trademark of Dupont Dow.
2Flow rate is dependent upon cartridge selection, fluid viscosity, and allowable pressure drop. See graph below for housing pressure drop at various flow rates. Refer to specific cartridge nomograph to determine initial pressure drop due to the filter cartridges. The 24FMO may be used to provide longer cartridge life and lower initial pressure drop. However, a flow rate in excess of 180 gpm (681 lpm) is not recommended with 2" (5.1 cm) connections.
3Ten-inch (25.4 cm) cartridges may be used instead of 20" (50.8 cm), 30" (76.2 cm), or 40" (102 cm) cartridges in 2, 3, or 4-deck housings, which will reduce this height. For 316 stainless steel spacers, specify part #T10583032.
