7/9/10/11 GPM Hydraulic Gear Pump, 3300 psi

Professional supplier hydraulic gear pump for sale. Displacement 7/9/10/11 Max. GPM for selection, working pressure 2600~3300 psi, speed 1500~2000 rpm, oil inlet/outlet ports thread 3/4 inch, small size, lightweight, high pressure, low price.

Specification

Note: 

1. Please use ATO gear pump with sufficient oil, otherwise there is a risk of burnout!
2. Calculate the actual displacement value according to the formula: Gallon/min=displacement (ml/rev)*rated speed 1500rpm/3785.41L (speed variation range 500rpm-3000rpm).

Features

• The hydraulic gear pump has 1 inlet and double outlet ports, which can change the direction of high-pressure oil output according to different rotation directions. It is equivalent to saving a reversing valve.
• Housing of the hydraulic gear pump is made of high-strength aluminum alloy, and the back cover is made of high-strength cast iron, which has high strength and good pressure resistance.
• Input shaft connection of the hydraulic gear pump is flat key. Connection of the inlet and outlet ports is 3/4” thread.
• The automatic compensation mechanism for axial and radial clearance enables the hydraulic gear pump to maintain high volumetric efficiency and mechanical efficiency for a long time.
• The hydraulic gear pump uses alloy steel gears, with small fluctuations, high pressure, low noise and stable performance.
• Hydraulic gear pump uses composite material bearings and high-performance sealing elements, has a small starting torque and good tightness, and can work efficiently under harsh working conditions.
• Oil inlet and outlet pipe joints of the hydraulic gear pump can realize multi-directional inlet and outlet, and support bidirectional rotation. Replace back cover, the hydraulic gear pump can be converted into a hydraulic motor, which meets the needs of different working conditions and save costs.

Tips: Precautions for using hydraulic gear pump.

1. The working oil temperature is -20℃ to 80℃.
2. When using hydraulic gear pump in winter, use 32# anti-wear hydraulic oil. When using hydraulic gear pump in summer, use 46# or 68# anti-wear hydraulic oil.
3. The working oil filtration accuracy of the hydraulic gear pump is ≤25μm.
4. When using hydraulic gear pump for the first time, pay attention to tighten the pipe joints and to remove the air from pipe and system, to avoid the 2-way gear pump from not working properly.
5. The front end of 2-way gear pump has no bearing and cannot bear radial force. If you need a radial bearing structure, you can contact us for customization.
6. The hydraulic gear pump can not be used for overspeed or overload, so as not to reduce the service life.
7. The external drain port of 2-way gear pump must be connected to the oil tank separately, and cannot be mixed with other oil return lines to avoid affecting normal operation.
