1. Product Overview

3525V-25A12-1CC-22R Fixed Double Vane Pump

Model: 3525V-25A12-1CC-22R

Type: Double Vane Pump

Material: Cast Iron

Application: Construction Machinery

Applicable Fluid: Hydraulic Oil

Maximum Operating Pressure: 172 bar

Speed Range: 600-1800 rpm

2. Working Principle

The V-series double pumps operate primarily based on the principle of a gear pump. Two gears, the pump body, and front and rear covers form two enclosed chambers. As the gears rotate, the volume of the chamber on the disengaged side expands, creating a vacuum that draws liquid in. The volume of the chamber on the engaged side decreases, squeezing liquid into the pipeline. This method of conveying liquid or increasing pressure through changes in working volume and movement makes the 3525V double pump highly efficient and stable in industrial applications.

3. Preparations

① Inspection:

Check the hydraulic pump and motor for signs of binding or stiffness.

Check that the packing is tight and that all connections are secure and reliable.

Check that the lubricant (grease) is adequate.

Check that the pressure gauge, safety valve, and relief valve are sensitive and functioning properly.

Check that the inlet and outlet valves are correctly positioned.

② Installation:

When installing a double pump, follow the manufacturer's installation instructions to ensure that the pump body is secure and properly connected.

During installation, avoid subjecting the pump body to excessive vibration and impact.

4. Maintenance

① Regular Inspection:

Regularly inspect the connection between the pump body and the motor to ensure the bolts are tight.

Check the lubricant level in the bearings to ensure it is adequate and refill or replace the lubricant promptly.

Check the tightness of the axial seal to ensure it is not overtightened or undertightened.

② Cleaning and Lubrication:

Regularly clean the pump body to remove oil and dust.

Ensure all parts are properly lubricated and replace the lubricant regularly.

③ Troubleshooting:

If the pump body exhibits abnormal vibration, noise, or leakage, immediately shut down the pump for inspection and take appropriate repair measures.
