    Constant-Flow-Rate Gear Pumps without Motor for Oil

    Image of Product. Front orientation. Gear Pumps. Constant-Flow-Rate Gear Pumps without Motor for Oil.
    A cast iron housing and steel gears allow these gear pumps to be used to dispense oil and fuel such as hydraulic oil and diesel fuel. Select your own motor to tailor them to your application. Use an air or electric motor with a coupling and belt/pulley drive. They produce a smooth flow of liquid for applications such as engine lubrication. All are self-priming, which means they create a suction force to draw liquid upward and fill the pump chamber. Do not use with solids.
    Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot run dry.

    Harsh-Environment Compact Constant-Flow-Rate Gear Pumps for Water and Oil

    Image of Product. Front orientation. Gear Pumps. Harsh-Environment Compact Constant-Flow-Rate Gear Pumps for Water and Oil.
    An aluminum enclosure around the motor provides protection in dusty and dirty environments. Designed to fit into small equipment, these pumps have miniature gears and a fractional horsepower motor for low-flow applications. 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.
    Note: If flow control is needed, place valves or reducers on the discharge side; never restrict the inlet of a pump with a valve or reducer.

    Harsh Environment Self-Priming Dewatering Pumps

    Image of Product. Front orientation. Dewatering Pumps. Harsh Environment Self-Priming Dewatering Pumps.
    This pump has a totally enclosed nonventilated (TENV) motor that is cooled by the liquid being pumped. Also known as a flexible impeller pump, it creates a suction force that can draw liquid upward to fill the pump chamber when your liquid source is below the pump. Mount up to 6 feet above your liquid source. Pump can pass solids up to 1/4" in diameter without clogging, so there’s no need to filter sediment and debris. A handle makes it convenient for on-the-go removal of bilge water, waste oil, and spills. Pump can also be used to cool marine engines and drain liquid from holding tanks.
    Note: Pump must be filled with liquid before use. It needs a constant flow of liquid and cannot run dry.

    Continuous-Duty Any-Direction Constant-Flow-Rate Diaphragm Pumps for Water and Coolants

    Image of Product. Front orientation. Diaphragm Pumps. Continuous-Duty Any-Direction Constant-Flow-Rate Diaphragm Pumps for Water and Coolants.
    Rated for continuous use, this diaphragm pump is often used to move caustics such as antifreeze and salt water. Mount it in any position, even upside down. It is typically used for low-flow spraying, draining, and washdown applications. The pump is self-priming, which means it creates a suction force to draw liquid upward. Pump can run dry and does not require an initial fill, so it’s a good choice for applications without a constant flow of liquid. Do not use with solids.
    Pressure Switch—Pumps with a pressure switch automatically shut off the pump at the maximum pressure.

    Self-Priming Circulation Pumps without Motor for Water

    Image of Product. Front orientation. Centrifugal Pumps. Self-Priming Circulation Pumps without Motor for Water.
    Also known as flexible impeller pumps, these create a suction force that can draw liquid upward to fill the pump chamber when your liquid source is below the pump. The impeller resists clogging and wear. Select a spark-free air motor for hazardous environments or attach an electric motor with a speed reducer or a belt pulley to alter the pump speed.
    Repair kits (sold separately) include components such as impellers, O-rings, and seal lips.
    Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot run dry.
