Model 52 Cast Iron Duplex Strainers 


View Pricing

Model 52 duplex strainerStainer basketThe Model 52 duplex strainer is made of cast iron for water applications and pipeline sizes from 10" to 18".  Diversion of flow is accomplished by (4) linked butterfly valves operated from a single gear operated hand wheel with a pointer that indicates which chamber is in service.


The special side entry strainer baskets remove damage causing particulate matter from the process media.  This unique design provides a straight through flow path resulting in a very low clean differential pressure. Both perforated and mesh lined strainer baskets have a pleated (convoluted) design, increasing the straining area while reducing size and weight of the basket itself.


Model 52 strainers have a threaded drain plug, enabling you to drain the cavity for inspection.  Heavy wall thickness combined with precision machined basket seats formulate a rugged pump suction strainer body with a tight sealing basket chamber. These pump suction strainers have all the features that you need and are usually available to within just a few weeks if the castings are in-stock.Model 73 suction strainer
