Fabricated Duplex Basket Strainers

To determine the anticipated maximum differential pressure (DP), it is common to request the DP at 75% blockage. At 75% blockage, there is a 75% reduction in flow area compared to clean, and a DP equal to approximately 4X that of the clean DP Value. This is based on a proportional analysis with open basket area being inversely proportional to DP.
