    High-Accuracy Metering Diaphragm Pumps for Chemicals

    Image of Product. Front orientation. Diaphragm Pumps.
    These diaphragm pumps meter a consistent amount of liquid within ±2% of the maximum flow. Often used to pump water-treatment chemicals, cleaning fluids, and electropolishing solutions, they have an adjustment dial that alters flow rate in 2% increments of the maximum flow. Pumps are self-priming and create suction to draw liquid upward. They can run dry but are not for use with solids.
    Pump Repair Kits—Repair kits include a pump head assembly, a diaphragm, valves, and seals.
