X. Operation and Maintenance Tips：

1. Pre-startup Inspection (Mandatory)

Confirm power supply voltage is AC220V with reliable grounding.

Inspect pump tubing, impeller, and seals for loose connections or foreign objects.

Verify the liquid in the barrel contains no particles, lumps, or high-viscosity solidified matter.

Insert the pump hose into the barrel, ensuring the impeller is fully submerged in liquid. Prohibit prolonged dry running.

For variable-speed motors, start at low speed and gradually increase.

2. Standard Operating Procedure

Place the barrel pump vertically into the barrel and position it steadily.

Connect the discharge hose, avoiding kinks or pressure buildup.

Connect power supply. Start at low speed to verify rotation direction and discharge flow.

Adjust speed as needed:

Rapid drum rotation: High speed

Precise dispensing / Foam-prone materials: Medium-low speed

Before shutdown, first turn off power, then remove pump body. Never remove pump under load.

After operation, promptly clean pump tubing to prevent material residue solidification.

3. Safety Operation Guidelines

*   Flammable/explosive liquids require EX explosion-proof models; standard motors are prohibited.

*   Keep pump body dry—do not expose to rain or submerge.

*   Avoid prolonged dry running (generally no more than 30 seconds) to prevent bearing and seal burnout.

*   Do not pump materials exceeding 1000 cPs viscosity, pastes, or particulate-containing substances.

*   Immediately stop operation and inspect if abnormal noise, vibration, or lack of flow occurs.

4. Daily Maintenance Techniques (Key to Extending Lifespan)

(1). Mandatory After Each Use

Flush the pump tubing with clean water or the corresponding solvent for 30 seconds to 1 minute.

Wipe the motor housing clean and store it dry.

(2). Weekly Maintenance

Inspect hoses and connectors for aging or leaks.

Check the pump inlet and impeller for entanglement or blockages.

(3). Monthly Maintenance

Check pump shaft for wobbling or abnormal noise.

Tighten connection screws to prevent loosening.

(4). Quarterly/Semi-Annual Maintenance

Disassemble and clean impeller, pump tube, and seal assembly.

Inspect bearing lubrication; replace oil seals/bearings if necessary.

5. Quick Troubleshooting for Common Issues

(1). No Liquid Discharge or Low Flow Rate

Causes: Pump not fully submerged in liquid, impeller clogged, speed too low, hose kinked.

Action: Submerge deeper → Clean impeller → Increase speed → Straighten hose.

(2). Liquid Leakage

Causes: Aged seals, cracked pump tubing, loose connections.

Action: Replace seals → Inspect tubing → Retighten connections.

(3). Excessive Vibration/Noise

Causes: Tilted pump body, impeller imbalance, foreign objects, bearing wear.

Action: Level pump → Clean impeller → Replace bearings.

(4) . Motor Overheating, Protective Shutdown

Causes: Overload, pressure buildup, prolonged high load, unstable voltage.

Action: Shut down and cool → Check for blockages → Reduce viscosity or replace with higher-power model.

6. 5 Golden Habits to Extend Service Life

Rinse three times rather than skip once: Material residue is the primary cause of pump damage.

Start and stop at low speed: Protects motor and seals.

Never run dry: Dry running severely damages pumps.

Vertical installation: Minimizes shaft eccentricity wear.

Keep spare parts stocked: Seal, impeller, and fittings should be pre-ordered; downtime costs far exceed part expenses.

7. Ready-to-Use Manual Summary
