    Constant-Flow-Rate Gear Pumps for Oil

    Image of Product. Front orientation. Gear Pumps. Constant-Flow-Rate Gear Pumps for Oil.
    A high-horsepower motor moves oil with a viscosity similar to SAE 60 motor oil. These gear pumps produce a smooth flow of liquid to lubricate equipment and blend oils. Motor is open dripproof (ODP) for use in clean, dry, and well-ventilated environments. 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.

    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.

    Hydraulic Gear Pumps

    These gear pumps have few moving parts so they're less prone to wear than other hydraulic pumps. Combine with an electric motor to generate flow in a hydraulic system. To mount to a NEMA C-face motor, use a Pump-to-Motor Mount (sold separately).
