Gear Pump
This gear pump is composed of gear, shaft, pump body, safety valve, and shaft-end seal. The gear, together with the shaft, is installed in the replaceable axle sleeve. Through hot treatment, the gear has high hardness and strength. The lubrication of the parts inside the product is completed simultaneously during medium output.
- By use of the reasonably designed unloading and return chute, the gear bears the minimum torque during operation, resulting in small load, minimum abrasion, and high efficiency.
- There is safety valve installed on the gear pump, offering overload protection. The total reflux pressure of the safety valve is 1.5 times of the rated discharge pressure. Regulation within permissible discharge pressure is available based on actual demand. Please note that this safety valve can not serve as reducing valve for long time. Extra reducing valve is required in case needed.
- Observing from the protruding end of the main shaft, the gear pump rotates clockwise.
- The industrial pump can be used as the fuel transfer pump and booster pump in fuel transfer system.
- For fuel system, our product can serve as the fuel pump for transferring, pressing, and injection.
- Application as lubrication pump is also available.
