This Duplex Basket Strainer is a special design with several important features and advantages for large size pipelines with high flow rates. Flow is switched from one basket chamber to the other by a pair of synchronized, high quality butterfly valves. This replaces the diverter plug used on smaller size strainers and gives a straight flow pattern with no sudden changes in flow direction. The result is a very low pressure loss A 10˝ strainer of this type, for example, can handle 2000 gpm of water with a pressure drop on only 2 psi. This is the strainer to choose when you have a high flow rate application and a low pressure loss is critical. Another important benefit of this new design is a saving in overall size. It is more compact than other large size duplex strainers – which means less weight and a smaller profile. This can be very important when space requirements are tight. This design also uses a new, unique basket design concept which incorporates a larger screening area. This is done by convoluting(pleating) the perforated sheet in the strainer basket, thus increasing the available screening area while reducing the total basket size. The flow enters the basket from the side, not the top – resulting in a straight-through flow pattern. What all this means in service is a lower pressure drop and greater time between basket cleanings than would be possible with standard-design baskets a real savings in time and operating costs.

Large size pipelines with high flow rates require a unique type of basket strainer. The typical design for smaller size pipelines just won’t perform efficiently the pressure loss would be too high and the baskets too large to remove and clean easily. These problems have been solved by the straight through flow design simplex basket strainer With this straight through flow, pressure loss is greatly reduced and, at the same time, results in a compact strainer that can fit in tight spaces. The basket that this strainer uses is special as well. The perforated or mesh straining screen in the basket is convoluted (pleated). This increases the amount of straining area available while at the same time reducing the overall basket size and weight.
