A gear pump is a simple in structure, highly reliable, and cost-effective positive displacement hydraulic pump. Due to its small size, light weight, convenient maintenance, and strong anti-pollution ability, it has become one of the most widely used power components in medium and low-pressure hydraulic systems. Its core function is to convert mechanical energy into hydraulic energy through the meshing movement of gears, providing stable medium and low-pressure oil output for various small and medium-sized industrial equipment. It is suitable for a variety of light and medium-load working conditions and is widely used in machine tools, construction machinery, agricultural machinery, mining equipment, petrochemicals, and other fields. It is an indispensable basic hydraulic component in industrial production.

The gear pump is driven by an independent motor, which can effectively eliminate upstream pressure pulsations and flow fluctuations. The pressure pulsation at the outlet of the gear pump can be controlled within 1%. When using a gear pump on the extrusion production line, it can increase the flow output speed and reduce the shear and residence time of the material in the extruder.
When the gear pump is working, the driving wheel rotates along with the motor and drives the driven wheel to rotate as well. When the meshing teeth on one side of the suction chamber gradually separate, the volume of the suction chamber increases and the pressure drops, thus drawing the liquid in the suction pipe into the pump; the sucked liquid is pushed in two directions in the gear teeth and sent to the discharge chamber. After the liquid enters the discharge chamber, due to the continuous meshing of the teeth of the two gears, the liquid is compressed and enters the discharge pipe from the discharge chamber. The driving gear and the driven gear rotate continuously,allowing the pump to continuously suck in and discharge the liquid.
A safety valve is installed on the pump body. When the discharge pressure exceeds the specified pressure, the conveyed liquid can automatically open the safety valve, allowing the high-pressure liquid to return to the suction pipe.

1. High reliability, suitable for harsh conditions: The structure is simple, and the core components (gears, pump bodies, etc.) are precisely machined and undergo special heat treatment, resulting in few wear parts and a low failure rate; it has strong anti-pollution capabilities and can adapt to various harsh industrial environments, reducing equipment downtime losses.
2. High cost-effectiveness, low maintenance costs: The manufacturing cost is low, and the processing of components is simple; the wear parts are easy to replace.
3. Stable performance, low energy consumption and loss: The volumetric efficiency reaches 85–95%, and the total efficiency is 75–90%, with low energy conversion loss; the noise is controlled at 65–75 dB (A), the operation is smooth, and there is no obvious pulsation in the oil output, ensuring the stable operation of the hydraulic system.
4. Wide adaptability, selectable specifications: Rated pressure 2.5–25 MPa, theoretical displacement 1–200 mL/r, suitable for various medium and low-pressure hydraulic systems; the material of gears and pump bodies can be selected (40Cr, HT200, etc.), which can meet different working condition requirements, and the application scenarios cover machinery, engineering, agriculture, and other fields.

1. During the operation of the gear pump, it is necessary to add grease frequently. The grease is prone to volatilize, so it is essential to pay attention to replenishing and replacing it. Additionally, keep the bearing area clean.

2. When using or after use, place the electric oil pump in a relatively dry, non-corrosive, and clean environment.

3. During the use of the gear pump, it is necessary to frequently inspect and maintain it. Pay attention to checking the electric oil tank to see if the power cord, internal wiring, plug, switch, and other components are still functioning properly; whether there are any damaged parts in the bearing components, etc.
