Cast Steel Duplex Strainers

 

Our carbon steel duplex strainers for ¾" to 24" size pipelines are listed below.  All flanged connections are ANSI class 150#.  You will note that the diverting valve style differs by strainer size.  The 53BTX ¾" through 4" sizes have a ball valve style diverter, the model 50 6" and 8" sizes use a tapered plug valve style diverter and the model 570 style uses a pair of sliding disc valves for flow diversion.  Each part number is hyperlinked to its' outline drawing which also contains additional specifications.

 

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 because 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" model 570 duplex strainers if your prefer this design.

 

If you require a higher pressure design or a larger strainer size we would provide the custom fabricated style.    Cast steel 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.
