MOQ: 100 PCS
Note: If you have any questions,please contact us
- 1.The fore pump and hind pumps are made of high-strength wear-resistant cast iron with strong bearing capacity
- 2.Adopt asymmetrical dual modulus shaping gears to effectively reduce noise
- 3.The combination of two different modulus oil pumps is suitable for the combination of large and small displacement
- 4.Axial clearance automatic compensation mechanism, so that the oil pump can maintain high volumetric efficiency for a long time
- 5.The connection form of the inlet and outlet ports is composed of a combination of thread and flange
