The common faults of ceramic plunger pumps mainly include leakage, pressure abnormality, insufficient or unstable flow, abnormal noise, pl wear or damage, blockage, motor or starting issues, and overheating, etc.

Hydraulic System Faults

‌Pressure Abnormality: Output pressure is too low, fluctuates greatly, or the hydraulic system makes loud noise, usually caused by insufficient hydraulic oil, pump wear, damage to the relief valve,logging of the oil filter, or air entering the system.

‌Insufficient Flow‌: Insufficient pump displacement or no flow may be caused by blockage of the su pipe, sticking of the suction valve/discharge valve, improper hydraulic system adjustment, or air leakage in the pipeline.

Seal and Plunger Faults

‌Leakage‌: Seals that are aged, worn, or improperly installed can cause oil or slurry leakage from the pump body, and scratches on the surface of ceramic plunger can also exacerbate leakage.

‌Plunger Wear or Damage‌: High-pressure reciprocating motion can easily cause deep grooves on the surface of plunger, or even breakage, due to pressure impact, coaxiality deviation, or manufacturing defects.

Operation and Drive Faults

‌Blockage‌ Impurities or solid particles can block the pump body or pipeline, and the filter system should be cleaned regularly.

‌Noise and Vibration‌: Abnormal noise be generated by friction between components, looseness, imbalance, or cavitation in the hydraulic system.

‌Motor Abnormality‌: Circuit faults, excessive temperature or motor damage may cause the pump to fail to start or operate instability.

‌Overheating‌: Insufficient lubrication, excessive load, internal leakage, or faults in cooling system can cause the pump body temperature to rise.
