Calculate the approximate clean differential pressure drop by selecting the strainer connection size, inputting your flow rate (GPM), inputting the specific gravity if other than water (sg of water = 1) and select the viscosity range if other than water (SSU of water = 30). Click "Update" to refresh the data and be sure that the clean differential is ≤2 PSI for the intended basket retention. NOTE: the differential pressure calculator is based upon the model 50 design for the 8" size and model 52 design for the 10" - 16" sizes. The model 570 has lower flow coefficient values and therefore a slightly higher clean differential pressure for a given flow rate. We will gladly assist you with the calculated clean differential pressure figures for the 8" - 16" model 570 duplex strainers.
If you require a higher pressure design or a larger strainer size we would provide the custom fabricated style. Cast iron duplex strainers usually ship within 72 hours after receipt of an order. If lead time is critical please contact us and we'll confirm the lead time required.
We wrote an article entitled BASKET STRAINERS: Differences between Simplex and Duplex Style Strainers which helps you decide if a duplex strainer is the best style for your application.
