Gear pump is formed by rely on the pump cylinder and the meshing gear working volume change and move to transport the liquid or causes the pressurization of the rotary pump. By two gears, pump body and cover of two closed space, when gears rotate, gear side space volume from small greaten, forming a vacuum, the liquid suction, the side of the gear mesh volume from large to small of the space, and the liquid in pipe line. Suction chamber and discharge chamber is separated by two gears meshing line. The gear pump outlet pressure depends on the size of the source resistance pump.

High pressure gear pump GPY series product features:

1. High efficiency, precise and detailed structure design, this series pump with high volumetric efficiency and high mechanical efficiency.

2. High reliability, light weight, tight and fine.

3. Advanced casting nature, to ensure stable and reliable performance.

4. The big flow of vane pump with low pressure high and low pump combination, reasonable use of primary energy and cost savings.

Note: 
1. Should be used with anti-foam, prevent oxidation and anti-corrosion additive such as mineral oil, oil of aniline point of 77-77 degrees

2. The recommended oil temperature: 10 to 60 degrees, the temperature limits, and 20 to 80 degrees

3. Recommend a suitable viscosity: 15-150 CST (15-150 was a/s), boundaries using viscosity: 10-430 CST (10-430 mm2/s)

4. Oil suction mouth pressure: -0.02-0.03 MPA (- 02-0.3 KGF/cm2), bottom temperature instant start Mpa (0.4 kgf/cm2)
