The company's new 500 series pumps are hydraulically actuated and available as simplex or duplex models.

  • Madden Manufacturing, Inc.

    Madden Manufacturing Inc. produces four series of diaphragm metering pumps all available as simplex, duplex and triplex models. With output ranges of 1 to 7 GPH, 5 to 90 GPH, and 96 to 180 GPH, the pumps provide repetitive accuracy of plus or minus 1 percent over a 10:1 turndown ratio. The pumps are designed for industrial jobs where chemicals must be pumped 24 hours a day.

  • AcuFlow

    AcuFlow designs four series of compact hydraulically-actuated diaphragm metering pumps capable of handling acids, bases, corrosives, hazardous chemicals and slurries. Depending on series, the pumps feature output ranges of 0.05 GPH to more than 1700 GPH at pressures up to 5,000 psi.

  • Jaeco Fluid Systems, Inc.

    Jaeco Fluid Systems Inc. offers electronically pulsed diaphragm metering pumps and hydraulically actuated diaphragm metering pumps. Used for low flow applications, the pulsed pumps feature a stroke rate that is manually adjustable for turn-down ratio of 10:1. The hydraulically actuated pumps used for leakproof metering of difficult-to-handle liquids, and available as simplex and duplex models.

  • Global Water Instrumentation, Inc.

    Global Water Instrumentation Inc. manufactures diaphragm metering pumps for chemical injection. Featuring a built-in diaphragm failure detection systems, the pumps provide maximum working pressure up to 175 psig, and can operate in fluid temperatures of 130F and ambient temperatures of 14 to 115F.

  • KNF Neuberger, Inc.
