These industrial-grade diaphragm metering pumps are designed to faithfully deliver chemicals 24 hrs/day for years, making “throwaway” pumps obsolete. This JR Series can handle flows from as low as 0.05 gal/hr up to 7 gal/hr. The integral worm gear reducer with steel worm gear and bronze driven gear is designed to give many years of service. Standard 48-fram TEFC foot-mounted motors for either 1- or 3-phase power are used. Washdown duty and explosion-proof motors are also available options. The manual output adjustment knob is located on top of the pump for easy operator access.
