    2. Calculate the actual displacement value according to the formula: Gallon/min=displacement (ml/rev)*rated speed 1800rpm/3785.41L (speed variation range 500rpm-3000rpm).

    Features

    • Hydraulic single gear pump uses high-strength aluminum alloy shell and alloy steel hard gear transmission, which is light in weight and stable in transmission.
    • Hydraulic single gear pump is suitable for SAE standard flange installation. The input shaft connection form is flat key shaft. Connection type of the oil inlet and outlet ports is threaded.
    • Hydraulic single gear pump has an automatic compensation mechanism for axial and radial clearances, which enables the oil pump to maintain high volumetric efficiency and high mechanical efficiency for a long time.
    • Hydraulic single gear pump uses SP gears, with small fluctuation, high pressure, low noise and stable performance.
    • DU composite material bearings and high-performance sealing elements, small starting torque, good sealing performance, and strong anti-fouling ability, so that hydraulic single gear pump can work efficiently under harsh working conditions.

    Tips: Commonly used calculation formula of hydraulic single gear pump.

    Motor power：W = P × q × n/54000 (kW)
    P = gear pump working pressure (MPa)
    Q = gear pump displacement (GPM)
    n = motor speed (rpm)

    Gear pump torque: T = P × q/1.7π（N.m）

    Motor torque: T = 9550 × W/n.

    Oil hose inner diameter matching: oil suction pipe inner diameter d = (0.12～0.18) × q × n
    q = gear pump displacement (GPM)
    n = motor speed (rpm)

    Note: tubing inner diameter d = (0.06～0.09) × q × n

    Oil return pipe inner diameter d = (0.09～0.12) × q × n

    Flow calculation: flow L = π × d2h/4000t (GPM)

    Piston rod diameter d (mm), piston rod stroke h (mm), working time t (s), displacement: q = 60 × L/n (ml/r)

    Based on the parameters of your Brown & Sharpe Rotary Gear Pump, we recommend this product.
    This pump can meet your needs. Please select "the "0.5 GPM" variant in the page drop-down menu, and check out the Dimensions Diagram down the page. Please note that our pump is 1mL/cycle, and your pump is 0.0003 gal/cycle. (~1.136mL/cycle)
    High efficiency hydraulic gear pump
    I purchased this hydraulic single gear pump for my fuel tank. Seems like it's very capable of doing job with high efficiency. Performed well, easy to use and compact structure. Highly recommend this gear pump.

    Gear Pump great work and cheap price
    Delivery product in time, immediately used this gear pump as soon as I got it.
    Amazing, it is comfortable to use as seller says. It I like this gear pump with good function and it works great. Adjustable operation makes pumping oil easily. Enough working efficiency and low price met me requirement.

    Does the good job
    I use this pump on a daily basis due to my job. Replacing oil out of generators engines. It will move it out quick and will back fill a unit with new oil by backfilling it.

    Excellent value for money
    This was to replace a bad pump on a semi-auto band saw. It works as it should and was hundreds of dollars less than if I had purchased the replacement from the mfgr of the bandsaw. Thank you.

    Works well
    The 3600 psi hydraulic single gear pump has been received. The model we want is the same as the ATO description. Enough pressure can make the work well. We installed it after receiving. The sound of the pump is low. We are very satisfied.
