Advantages & Disadvantages (summary)

• Advantages: accurate dosing, compact footprint, straightforward integration, energy-efficient for intermittent operation
• Disadvantages: limited flow capacity for high-volume needs, potential vibration/noise, heat generation during continuous duty; not suitable for high-viscosity or particle-laden fluids

Maintenance & Troubleshooting (summary)

• Regularly clean filters and flow channels; inspect wiring and connectors
• Avoid running the pump dry; use compatible materials for aggressive chemicals
• Check voltage supply, wiring, trapped air, blocked inlet/outlet, worn parts and valve function for common faults
• Reduce duty cycle or improve ventilation to mitigate overheating; check mounting and operating frequency to reduce vibration
