Notes: Specifications may vary slightly depending on model variations and application requirements.
Place the pump on a stable and flat surface to prevent tipping or vibration.
Connect inlet and outlet hoses securely, ensuring proper flow direction.
Verify that electrical or mechanical drive connections are correctly configured and comply with safety standards.
Check the oil reservoir to ensure sufficient fluid supply before operation.
Prime the pump by allowing oil to fill the inlet line.
Start the pump at low speed, gradually increasing to operational speed.
Monitor pressure, flow rate, and noise during initial operation.
Avoid running the pump dry to prevent internal damage.
Maintain consistent oil viscosity and quality for optimal performance.
Observe operational limits for pressure and temperature to prevent premature wear.
Gradually close inlet and outlet valves to stop oil flow.
Allow the pump to cool down before performing any maintenance.
Inspect for leaks, worn seals, or other damage before storing or restarting.
Lubrication: Regularly check and lubricate moving components to maintain smooth operation.
Hose Management: Avoid sharp bends and kinks in hoses to ensure consistent flow.
Cleaning: Clean external surfaces to prevent dust and debris from entering the pump system.
Temperature Monitoring: Ensure oil temperature remains within the recommended range to prevent viscosity issues.
Storage: Store the pump in a dry, protected environment when not in use.
| Component | Frequency | Action |
|---|---|---|
| Bearings | Every 3 months | Lubricate and inspect for wear |
