    Air-Powered Constant-Flow-Rate Piston Pumps

    Image of Product. Front orientation. Piston Pumps. Air-Powered Constant-Flow-Rate Piston Pumps.
    Commonly called piston pumps, these are often used in high-pressure applications, such as hydrostatic testing of pipelines, tanks, and valves. Flow and outlet liquid pressure can be controlled by varying the air pressure. To calculate discharge liquid pressure, multiply the air pressure by the ratio shown in the table. Pumps are self-priming, which means they create a suction force to draw liquid upward to fill the pump chamber.
    Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot run dry.

    High-Pressure Constant-Flow-Rate Pumps without Motor for Pressure Washing

    Image of Product. Front orientation. Plunger Pumps. High-Pressure Constant-Flow-Rate Pumps without Motor for Pressure Washing.
    Also known as plunger pumps, these can provide pressures up to 3,000 psi. Use them for washdowns, drain jetting, and other pressurized water-spraying applications. Connect them directly to an electric motor to alter the pump speed. Pumps are gravity fed and require an elevated liquid source to fully fill the pump before turning on. Do not run dry or use with solids.

    Lightweight Plastic Gasoline-Powered Dewatering Pumps

    Image of Product. Front orientation. Dewatering Pumps. Lightweight Plastic Gasoline-Powered Dewatering Pumps.
    With a polypropylene housing, these pumps are about half the weight of other gasoline-powered pumps. Fill the fuel tank with gasoline to remove water at sites without power. Pumps are self-priming, which means that they create a suction force to draw liquid upward and fill the pump chamber. Mount up to 20 feet above your liquid source. They have a pull-start engine.
    Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot run dry.
    Cannot Be Sold to Canada—Pumps cannot be sold to Canada due to import regulations.
