JN Series Diaphragm Metering Pumps 5 simplex models, 1-7 GPH capacity, up to 250 psi. These simple, rugged, accurate diaphragm type metering pumps are used in many industrial plants for injecting a controlled flow of highly reactive liquids such as acids, caustics and water treatment chemicals. Heavy duty industrial grade construction means these tough little pumps will deliver many years of trouble free 24-7-365 pumping. Simplex is shown. Duplex and triplex pumps also available.
MetriFlow Diaphragm Metering Pumps 3 Series: JN Series (up to 7 GPH), MF Series (up to 75 GPH), and MH Series ( Up to 180 GPH). These simple, rugged, accurate mechanically actuated diaphragm type metering pumps are used for injecting a controlled flow of highly reactive liquids such as acids, caustics and water treatment chemicals. Heavy duty industrial grade construction means these tough pumps deliver many years of trouble free 24-7-365 pumping. The double diaphragm construction option protects pump from leaking corrosive liquids.
MF Series Diaphragm Metering Pump 12 simplex models, 5-75 GPH capacity, up to 300 psig. Madden diaphragm metering pumps are designed for tough industrial jobs where chemicals must be pumped 24 hours a day, 365 days a year. Engineered materials are used for the wetted end to pump virtually any chemical, from acids to caustics. Even viscous liquids and suspended solids can be pumped with volume controlled accuracy. Mechanically activated diaphragm type metering pumps are are simple and rugged in design. The manual output adjustment knob is located conveniently on the top of the pump body. For automatic output control with a 4-20 mA instrument signal several variable speed drive packages of controller and motor are available. The worm gear reducer has integral steel worm drive shaft and a bronze worm gear, continuously splash lubricated with ISO grade 460 worm gear reducer oil for extended gear and bearing life. Standard motors are 56 frame foot mounted, 1,725 rpm, TEFC. Repetitive accuracy is +/- 1%. Simplex, duplex, triplex and quadruplex pumps are available.
