Rated to a maximum flow rate of 30 GPM (114 liters per minute), this strainer uses a stainless steel screen to protect downstream components from particulate contamination. The built-in bypass prevents system starvation when the screen approaches restriction. At 3.47 inches in diameter and 8 inches in length, it connects via a 1-1\/2 inch NPT threaded port. Hydraulic technicians and industrial plumbers typically install this unit on pump inlet lines where suction-side protection is required.\u003c\/p\u003e\n\u003cp\u003eThis strainer is suited for industrial hydraulic systems, fluid power circuits, and pump inlet applications where continuous flow protection and bypass capability are necessary. It handles operating conditions up to 195 degrees F and a maximum working pressure of 3 psi. The threaded NPT connection simplifies installation in standard pipe assemblies. Applications span mobile hydraulics, stationary power units, and industrial fluid systems where contamination control at the suction port is a maintenance priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaximum flow rate of 30 GPM (114 liters per minute) for suction-side filtration\u003c\/li\u003e\n  \u003cli\u003eIntegral bypass prevents pump starvation under restricted-flow conditions\u003c\/li\u003e\n  \u003cli\u003eStainless steel screen material for durability and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch NPT threaded connection for standard pipe compatibility\u003c\/li\u003e\n  \u003cli\u003eRated to 195 degrees F maximum working temperature\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 3.47 inches diameter and 8 inches length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style suction strainer replacement for hydraulic pump inlet lines using 1-1\/2 inch NPT threaded connections in systems operating within the rated flow, pressure, and temperature limits.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified hydraulic technician or industrial pipefitter. Depressurize and drain the system fully before removing or installing any suction-side strainer. Apply thread sealant appropriate for the fluid type to the NPT threads and tighten to standard practice for the pipe size. Verify that system suction conditions remain within the 3 psi maximum working pressure rating to ensure proper bypass function.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Flow Rate\u003c\/strong\u003e: 30 GPM (114 liters per minute)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: 1-1\/2 inches NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3.47 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 3 psi (0.2 bar)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 195 degrees F (90 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScreen Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHas Bypass\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.62 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40161515\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 937489\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542661529906,"sku":"937489","price":102.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b65fc66787f0e159eea1c695e98384b_2aad40cd-ec97-4ba9-a0b0-84e843308730.jpg?v=1785904226","url":"https:\/\/voomisupply.com\/products\/parker-937489-suction-strainer-with-bypass-30-gpm-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
