During the peak of the growing season, even a single day without precise chemical injection can result in visible crop loss, nutrient deficiencies, and costly setbacks for your nursery or greenhouse operations. Global supply chains remain unpredictable, and waiting for critical repair components during a heat wave is a risk your business cannot afford. By securing your replacement plunger assemblies now, you eliminate the threat of downtime and ensure your crews are ready to perform emergency maintenance before a minor wear issue becomes a catastrophic failure.\u003c\/p\u003e\u003cp\u003eThe Dosatron DM11F Plunger Assembly is engineered with high grade chemical resistant materials that outperform generic seals and third party components. This technical advantage ensures consistent volumetric proportioning even under varying flow rates, which reduces the need for frequent recalibration and manual monitoring. Investing in genuine Dosatron parts protects the internal integrity of the injector body and extends the service life of the entire unit. By maintaining a stock of these essential components, you demonstrate a level of professionalism that minimizes labor costs and provides your clients with the reliability they expect from a top tier irrigation specialist.\u003c\/p\u003e\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eHigh Grade Chemical Resistant Composite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eDosatron DM11F Fixed Ratio Injectors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComponent Type\u003c\/td\u003e\n\u003ctd\u003eInternal Plunger Assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Pressure\u003c\/td\u003e\n\u003ctd\u003eRefer to Injector Body Rating\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Color\u003c\/td\u003e\n\u003ctd\u003eBlack \/ Neutral\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eApproximately 0.1 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eAvailable Models \u0026amp; Sizes\u003c\/h3\u003e\u003cp\u003eThis plunger assembly is specifically designed for the DM11F fixed ratio models.

Use a standard strap wrench or the provided Dosatron tool to unscrew the bell housing and access the internal piston. When installing the new DM11F plunger assembly, apply a thin layer of manufacturer approved silicone lubricant to the seals to ensure smooth travel and prevent binding during the initial startup. Always check local plumbing codes regarding backflow prevention when utilizing chemical injection in potable water systems.\u003c\/p\u003e","brand":"Dosatron","offers":[{"title":"Default Title","offer_id":52158390173985,"sku":"120793","price":26.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/8458\/3969\/files\/120793_PR.png?v=1766259740","url":"https:\/\/asiwsupply.com\/products\/dosatron-dm11f-plunger-assembly","provider":"ASIW","version":"1.0","type":"link"}
