PLP20.6,3-D03S1-LOD Hydraulic Gear Oil High Pressure Pump PLM PLP PLP30 PLP20 PLP10 PLM20 Series

1. Technical parameters
Displacement: Approximately 6.3 cubic centimeters per revolution.
Maximum peak pressure: Up to 300bar (approximately 4350psi).
Maximum rotational speed: 4000min ⁻ ¹
Suction pressure range: 0.7-3bar (abs.).2. Working Principle
This gear pump is an external meshing gear pump, composed of intermeshing gears, a pump casing, front and rear end covers, etc. When the driving gear is driven to rotate by the motor, it drives the driven gear to rotate in the opposite direction. In the oil suction chamber, the gear teeth gradually disengage from meshing, and the volume between the teeth gradually increases, creating a local vacuum. Under the action of atmospheric pressure, the liquid enters the pump from the oil suction port. As the gears rotate, the liquid is carried by the gear teeth to the oil discharge chamber. In the oil discharge chamber, the gear teeth gradually engage, and the volume between the teeth gradually decreases. The liquid is squeezed and discharged from the oil discharge port, thus achieving continuous liquid transportation.

3. Product features and advantages
Compact structure: It adopts a high-strength aluminum alloy pump body, which is small in size and light in weight, making it easy to install and arrange.
Heavy-load adaptability: Equipped with built-in shaft end support bearings, it can be used in heavy-load working conditions, enhancing the reliability and service life of the pump.
Flexible configuration: It features a variety of international standard shafts, flanges and ports to choose from, supporting the combined use of multiple pumps. Pumps of different series and discharges can be cascished. Additionally, various built-in valves such as oil replenishment valves, relief valves and priority valves can be selected according to requirements, simplifying the design of hydraulic pipelines and enhancing system efficiency.
Good heat dissipation: As a member of the electro-hydraulic air-cooled series, it has excellent heat dissipation performance and can operate stably for a long time in harsh environments.

4. Usage functions and purposes
The main function is to convert mechanical energy into hydraulic energy, provide pressure oil for the hydraulic system, and achieve the transportation and pressurization of liquids. The output flow can be controlled by adjusting the rotational speed or by matching a throttle valve, etc.
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 as the power source of the lubricating oil circulation system in the lubrication system. It can also be used in the fuel system for transporting fuel and so on.

5. Applicable machines and scenarios
