    Measure how high and far your system needs to move liquid. Then compare pumps by priming methods and flow control types.

    Fixed-Flow-Rate Peristaltic Pumps for Chemicals

    Image of Product. Front orientation. Peristaltic Pumps. Fixed-Flow-Rate Peristaltic Pumps for Chemicals.
    Also known as tubing pumps, these maintain a fixed flow rate. Pumps are self-priming, which means they create a suction force to draw liquid upward and fill the pump chamber. Mount them up to 25 feet above your liquid source. All can run dry. Do not use with solids.

    2 amp

    Rated for liquids with a viscosity up to 5,000 centipoise, these pumps can be used with thick chemicals such as electropolishing solutions. An adjustment dial allows you to alter flow rate in 2.5% increments of the maximum flow without the hassle of changing tubing. Often used in boiler feed systems and water treatment, they're compatible with chemicals such as cleaning fluids and acid-washing solutions. Pumps are self-priming and create suction to draw liquid upward. They can run dry.
