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: Hydraulic triple gear pump maintenance.

According to the season, add or replace the hydraulic oil that meets the requirements to the specified oil level for the hydraulic triple gear pump. Take out the foreign matter in the oil pipe and tighten the bolt or nut of joint.
Replace the aging or damaged skeleton oil seal or O-shaped sealing rubber ring.
Replace worn gears or sleeves. If the wear degree slight, grind the end face smooth on flat plate. The allowable error of unevenness is 0.03mm, and the end face of the upper shaft sleeve is lower than the upper plane of the pump body (the normal value is lower than 0.10~0.15mm).
The unloading groove on shaft sleeve must be installed on the side of the low pressure chamber to eliminate the harmful dead volume generated when the gear meshes.
Before pressing in the self-tightening oil seal, a layer of lubricating oil should be applied to its surface. Note that the oil blocking edge faces the front cover and cannot be installed backwards.
After disassembling the hydraulic triple gear pump, thoroughly clean the pump body and internal parts before replacing the seals. Dip kerosene with fine sandpaper and gently push it flat, and then install a new seal.
