Technical Parameters
|
Standard Range
|
Parameter Explanation & Application Tips
|
|---|---|---|
|
Displacement
|
120 cc/r – 750 cc/r
|
Displacement refers to the volume of fluid required for the motor to complete one full rotation (excluding leakage). A larger displacement means higher torque output, suitable for heavy-load scenarios such as mining machinery and construction equipment.
|
|
Continuous Pressure
|
18 MPa – 26 MPa
|
The maximum pressure that the motor can withstand during long-term continuous operation, complying with industrial high-pressure standards. It is compatible with 18MPa-32MPa pressure level hydraulic systems, ensuring stable operation in high-pressure working conditions.
|
|
Peak Pressure
|
Up to 30 MPa
|
The maximum instantaneous pressure that the motor can bear in short-term overload operation, which is 10%-15% higher than the continuous pressure, effectively resisting load impact.
|
|
Continuous Torque
|
320 Nm – 1500 Nm
|
Torque is a measure of rotational force, calculated as the product of force and the distance from the center of rotation. The continuous torque range ensures stable power output for heavy-load equipment such as excavators and harvesters.
|
|
Continuous Speed
|
110 rpm – 880 rpm
|
The stable speed range during long-term operation, suitable for low-speed and high-torque scenarios. The precision gear transmission design ensures smooth operation even at the minimum continuous speed.
|
|
Max Flow Rate
|
Up to 160 L/min
|
The maximum volume of hydraulic fluid that the motor can input per minute, directly affecting the motor’s speed and power output. It matches the flow output of mainstream hydraulic pumps in the industry.
|
|
Operating Temperature
|
-45℃ ~ 105℃
|
The temperature range suitable for long-term operation, with strong high and low temperature adaptability. It can work stably in cold areas and high-temperature industrial environments, reducing downtime caused by temperature issues.
|
|
Protection Level
|
IP67
|
With excellent waterproof, dustproof, and anti-corrosion performance, it can adapt to harsh outdoor working environments such as construction sites, mines, and farmlands, extending the service life.
|
|
Certifications
|
CE, ISO 9001, ISO 14001, GB/T 28007.1-2011
|
Complies with international and national industry standards, ensuring product quality and safety, and can be widely used in domestic and overseas markets.

Key Parameter Matching Guidelines
-
Displacement & Torque Matching: For heavy-load equipment (such as mining machinery and large excavators), select models with large displacement (500 cc/r – 750 cc/r) to ensure sufficient torque output; for light-load and high-efficiency scenarios (such as small material handling equipment), select small-displacement models (120 cc/r – 300 cc/r).
-
Pressure & Flow Matching: The motor’s continuous pressure should be 5%-10% lower than the hydraulic system’s working pressure to avoid overload; the max flow rate should match the hydraulic pump’s output flow to ensure stable speed and power.
-
Temperature & Environment Matching: For high-temperature environments (such as smelting workshops), pay attention to the motor’s heat dissipation performance; for low-temperature environments (such as cold regions), select models with low-temperature resistance to ensure smooth startup.
