Note:
- Please use ATO gear pump with sufficient oil, otherwise there is a risk of burnout!
- 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 triple gear pump uses high-strength aluminum alloy shell and alloy steel hard gear transmission, which is light in weight and stable in transmission.
- Installation of the hydraulic triple gear pump is SAE 2-bolt standard flange. Input shaft connection is woodruff key. Connection type of the oil inlet and outlet ports is thread.
- Hydraulic triple 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 triple gear pump uses SP gears, with small fluctuation, high pressure, low noise and stable performance.
- Hydraulic triple 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.
- The front and rear gear pumps work independently of each other, and any combination of displacements can be customized according to requirements.

Tips: How to extend service life of the hydraulic triple gear pump?
- Use a kerosene brush to clean the gear surface of hydraulic triple gear pump, and then use a whetstone to clean up the debris left during boring.
- Be careful not to install the right-handed pump on the left-handed pump, otherwise the skeleton oil seal of hydraulic triple gear pump will be damaged.
- Before installing the pump cover, pour a small amount of hydraulic oil into the housing of the hydraulic triple gear pump, and turn the meshing gear by hand.
- After installing the hydraulic triple gear pump, before tightening bolts, check whether the gap between the pump cover and pump body is between 0.3~0.6mm. If the gap is too small, replace the large sealing ring. After all installations are completed, check to make sure that the rotation is flexible and no jamming.
- When oil leaks from the inlet and outlet ports of hydraulic triple gear pump, use sandpaper to flatten the joint surface of the two, and replace the appropriate sealing rings. Polish the chamfered burr of the threaded connection port with a whetstone, and replace the intact sealing ring (pad). It is strictly forbidden to wind it with various types of sealant and raw material tape.
