The recommended kinematic viscosity is 42-74mm²/s at a temperature of 40℃. You can select specific hydraulic oil based on your actual ambient temperature and workload.
When the oil return port pressure exceeds 10MPa (and rotation speed is below 200rpm), pressure relief must be performed through the leakage port, ideally connecting it directly to the tank.
We recommend a filter filtration accuracy of 10-30 microns. Installing a magnetic block at the bottom of the tank is highly suggested to capture metal particles.
To maximize life, load the motor for one hour at 30% of the rated pressure during initial setup. Always ensure the motor is filled with oil before loading.
The normal working oil temperature is between 20℃ and 60℃. The maximum system operating temperature is 90℃, though this should not exceed one hour of continuous operation.
Yes, these motors are designed for versatility and can be used in either series or parallel connections depending on your system's flow and pressure requirements.
