2. Power Supply Requirements

• Confirm that three-phase voltage matches the pump’s specification.

• Use proper circuit protection to avoid damage from overcurrent or short circuits.

3. Fluid Compatibility

• Only circulate fluids compatible with pump materials (stainless steel and corrosion-resistant alloys).

• Avoid highly abrasive fluids to prevent excessive wear on impellers and seals.

4. Temperature and Pressure Limits

• Operate the pump within the specified temperature range (-20°C to +120°C).

• Do not exceed the maximum pressure rating of the pump to prevent damage.

Operation Tips

1. Pre-Startup Checklist

• Inspect the pump and motor for visible damage or leaks.

• Ensure all valves and connections are properly secured.

• Fill the pump casing with appropriate lubricants or fluids if required.

2. Startup Procedure

1. Confirm that the power supply is correct and grounded.

2. Open inlet and outlet valves gradually to avoid sudden pressure surges.

3. Start the pump at low speed (if variable speed is supported) to check for smooth operation.

4. Monitor pressure, flow rate, and temperature during the initial startup.

3. Operational Monitoring

• Regularly check for unusual noise, vibration, or temperature rise.

• Maintain a log of operating parameters for predictive maintenance.

• Use appropriate sensors to monitor pressure and flow fluctuations.

Proper inspection and maintenance are critical for reliable and safe operation of the HWB Three-Phase Explosion-Proof Pump.

1. Routine Inspection

• Monthly visual inspection of pump casing, seals, and electrical connections.

• Verify the integrity of explosion-proof enclosures.

• Check for corrosion, wear, or leakage.

2. Lubrication

• Lubricate bearings, motor, and moving parts every 6 months or per manufacturer recommendations.

• Use high-temperature and chemically resistant lubricants.

3. Cleaning

• Flush the pump with clean water or compatible fluids after each operational cycle.

• Avoid using strong acids or alkalis for cleaning that may damage pump surfaces.

4. Component Replacement

• Replace worn impellers, seals, or bearings immediately to prevent performance degradation.

• Keep spare parts kits on-site for quick maintenance.
