Rated at 1\/12 horsepower and capable of delivering up to 3.00 GPM, this pump features a built-in demand switch that automatically starts and stops the pump in response to system pressure. The wetted components are constructed from polypropylene, making it suitable for use with a range of compatible liquids where chemical resistance is a priority. Licensed plumbers, irrigation technicians, and spray system installers typically work with this class of pump in low-flow, on-demand circuits.\u003c\/p\u003e\n\u003cp\u003eThis pump is well suited for residential and light commercial applications including demand-based spray systems, chemical dosing, RV water supply, and small-scale pressure boosting. The 1\/2-inch inlet and 1\/2-inch outlet ports allow straightforward integration into standard low-flow plumbing circuits. The DC power input makes it a practical choice for off-grid setups, mobile installations, and 12-volt systems where AC power is not available or practical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuilt-in demand switch automatically activates and shuts off the pump based on downstream pressure draw\u003c\/li\u003e\n  \u003cli\u003e1\/12 HP DC motor provides efficient low-draw operation suitable for 12-volt systems\u003c\/li\u003e\n  \u003cli\u003eMaximum flow rate of 3.00 GPM for low-flow spray and transfer circuits\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch inlet and 1\/2-inch outlet ports for standard small-bore plumbing connections\u003c\/li\u003e\n  \u003cli\u003ePolypropylene construction on wetted parts offers resistance to many common chemicals and corrosion\u003c\/li\u003e\n  \u003cli\u003eDiaphragm pump design supports self-priming and dry-run tolerance typical of this pump type\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit pump for demand-based spray and transfer systems requiring a 1\/12 HP DC diaphragm pump with 1\/2-inch ported connections and automatic demand switching.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified technician familiar with low-voltage DC plumbing systems. Disconnect and lock out all power sources before servicing or making any connections. Verify that inlet and outlet plumbing is free of obstructions and that port connections are sealed properly to prevent air ingestion, which can affect diaphragm pump performance. Follow all applicable local plumbing codes and the manufacturer installation instructions for mounting orientation and wiring polarity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower\u003c\/strong\u003e: 1\/12 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Flow Rate\u003c\/strong\u003e: 3.00 GPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Type\u003c\/strong\u003e: DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.4 pounds\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: PENTAIR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2088-343-135\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PENTAIR","offers":[{"title":"Default Title","offer_id":51541895905586,"sku":"2088-343-135","price":232.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/99d6c81f0d44321aa3c10d28ffcbd29b.jpg?v=1785887547","url":"https:\/\/voomisupply.com\/products\/pentair-2088-343-135-diaphragm-pump-1-12-hp-3-gpm","provider":"Voomi Supply","version":"1.0","type":"link"}
