External Gear Pumps

External Gear Pumps are engineered for precise, high-pressure fluid transfer in demanding applications. These positive displacement pumps offer consistent flow, excellent volumetric efficiency, and superior durability, making them ideal for handling oils, fuels, chemicals, and viscous liquids.

  • External Gear Pumps are compact, high-precision positive displacement pumps ideal for transferring clean, lubricating fluids at consistent flow rates and pressures. Featuring two intermeshing gears — one driving and one driven — these pumps trap fluid between the gear teeth and pump casing, creating a smooth and controlled flow. Known for their simplicity, reliability, and ability to handle a wide range of viscosities, external gear pumps are a popular choice for industrial fluid handling, lubrication systems, and chemical dosing.


    KEY FEATURES INCLUDE:

    • Consistent, pulse-free flow – excellent for metering and process control

    • High-pressure capability – ideal for demanding industrial systems

    • Compact and robust design – fits easily into tight spaces and OEM equipment

    • Wide viscosity range – handles thin oils to heavy lubricants with ease

    • Reversible flow – suited for flexible system designs

  • External Gear Pumps are used across numerous industries where precise fluid transfer, lubrication, or dosing is required. 


    COMMON APPLICATIONS INCLUDE:

    • Hydraulic systems - Used in power units, machinery, and mobile equipment for oil circulation and pressure generation.

    • Lubrication systems - Delivers consistent oil flow to gears, bearings, and rotating equipment in compressors, turbines, and gearboxes.

    • Chemical dosing and transfer - Handles solvents, resins, and additives with accuracy in processing and manufacturing environments.

    • Paints, coatings, and inks - Provides smooth, pulse-free transfer of low to medium-viscosity fluids with minimal shearing.

    • Food-grade and pharmaceutical processes - Pumps edible oils, flavorings, and clean fluids when constructed from appropriate materials.

    • Fuel handling and transfer - Transfers diesel, kerosene, and other fuels in small-scale or precision delivery systems.

  • We supply a range of external gear pumps tailored for industrial, hygienic, and OEM applications.
