Product Description
PGI102 PGI101 PGI103 PGI102-2 PGI102-3 PGI102-6 High Pressure Hydraulic Pump PGI102-3-020-RK23-10-6100 Servo Gear Pump
Displacement: Approximately 20 cubic centimeters per revolution.
Rated pressure: Up to 330bar.
Maximum pressure: Up to 350bar.
Rotational speed: Up to 4000rpm.2. Working Principle
The gear pump PGI102-3-020-RK23-10-6100 belongs to the internal meshing gear pump. Its working principle is based on two meshing gears rotating inside the pump casing. When the driving gear rotates, it drives the driven gear to rotate in the opposite direction. On one side of the suction port, the teeth of the two gears gradually disengage from meshing, causing the volume of the sealed working chamber in this area to gradually increase, creating a local vacuum. Under the action of atmospheric pressure or liquid pressure, the liquid is forced into the suction chamber of the pump from the suction pipe. As the gear continues to rotate, the liquid that has been sucked in is carried by the gear teeth and moves along the inner wall of the pump casing from the suction port side to the discharge port side. On one side of the liquid discharge port, the teeth of the two gears start to re-engage, causing the volume of the sealed working chamber in this area to gradually decrease. The reduction in the volume inside the chamber exerts a squeezing effect on the liquid, thereby discharging it from the liquid discharge port at a relatively high pressure.
3. Product features and advantages
High pressure: The rated pressure can reach 330bar, and the maximum pressure is 350bar, which can meet the requirements of high-pressure systems.
Wide speed range: The maximum speed can reach 4000rpm, which can adapt to different working scenarios and requirements.
Low noise: The structural features of the internal gear pump result in a relatively low noise level during operation.
Compact structure: The overall structure design is compact, occupying a small space and being convenient for installation and layout.
Strong self-priming ability: It is not sensitive to oil contamination and can ensure the stability and reliability of the system to a certain extent.
4. Usage functions and purposes
The main function is to convert mechanical energy into hydraulic energy, provide pressure oil for the hydraulic system, achieve the transportation and pressurization of liquids, and control the output flow by adjusting the rotational speed and other means.
Application: It can be used in hydraulic systems to provide power for actuating elements such as hydraulic cylinders and hydraulic motors. It can also be used in lubrication systems as the power source of the lubricating oil circulation system. It can also be used in the fuel system to pump fuel from the storage tank to the engine combustion chamber, etc.
5. Applicable machines and scenarios
Applicable machines: Applicable to construction machinery, such as excavators, loaders, rollers, etc. It can also be used in plastic injection molding machines, presses, machine tools and other equipment in the industrial manufacturing field, as well as related hydraulic systems in the fields of ships, aviation, etc.
It is widely used in scenarios that require high-pressure and stable flow hydraulic power, such as material handling in construction and component processing in industrial production.
6. Similar models
The PGE series external gear pumps share certain similarities in basic performance with the PGI series internal gear pumps, but they differ in structure and specific parameters. The PGE series external gear pumps have a rated pressure of up to 250bar, a maximum pressure of 280bar, and a speed as high as 3500 revolutions per minute.

Before starting: The pump chamber and the suction pipeline must be filled with the conveyed medium. Open the exhaust valve to release the air. Dry operation is strictly prohibited. At the same time, the concentricity of the coupling between the pump and the motor should be checked to ensure that the suction pipeline is well sealed and the suction height meets the design requirements.
During operation: The cleanliness and viscosity of the medium must be strictly controlled. A 100-200 mesh suction filter can be installed and the filter residue should be cleaned regularly. Monitor the temperature, pressure and sound of the pump in real time. The temperature of the casing should be ≤70℃, the temperature of the bearing should be ≤80℃, and the outlet pressure must not exceed the rated value. If any abnormal sound occurs, stop the machine in time for inspection.
Shutdown and maintenance: When shutting down, the outlet valve should be closed first, and then the motor power supply should be cut off to prevent the medium from flowing back and impacting the gears. When the pump is shut down for a long time, the medium in the pump cavity should be drained, the bearing grease should be replaced regularly, and the sealing performance of the shaft seal should be checked. If leakage is found, the sealing ring should be replaced in time.
