{"product_id":"dosatron-d128r-actuator-spring","title":"Dosatron® D128R Actuator Spring","description":"\u003ch3\u003eProduct Overview\u003c\/h3\u003e\u003cp\u003eA snapped or fatigued actuator spring can bring your entire fertigation system to a grinding halt during the height of the growing season. When injection pumps fail, your crops lose vital nutrients, leading to stunted growth or total plant loss that can devastate a season's yield. With peak demand placing strain on supply chains, waiting for a backordered component can result in costly project delays and frustrated clients. Maintaining a stock of these essential springs ensures you can perform immediate on-site repairs, keeping your systems running and your production schedules on track regardless of external shortages.\u003c\/p\u003e\u003cp\u003eThe Dosatron D128R Actuator Spring is engineered specifically for the precision requirements of chemical injection rather than being a generic hardware store substitute. Its precise tension rating ensures consistent piston movement, which maintains the accurate dilution ratios your professional clients demand. By choosing the genuine manufacturer replacement, you reduce the risk of premature failure and the labor costs associated with repeated service calls. Having these small but critical components in your service kit gives your crew a competitive advantage by allowing for preventative maintenance that avoids expensive emergency repairs and protects your reputation for reliability.\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 Stainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eDosatron D128R Series Models\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComponent Type\u003c\/td\u003e\n\u003ctd\u003eInternal Actuator Spring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Rating\u003c\/td\u003e\n\u003ctd\u003eMatches System Operating Standards\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eManufacturer Certified Replacement Part\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eNatural Metallic\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 actuator spring is designed for the D128R series injectors; however, we stock a wide range of springs for various Dosatron pump capacities.
