The unusual noise coming from the piston pump can be a sign of a variety of problems to look out for. Here are some steps to take to deal with abnormal noise from a piston pump head:
1.Identify the type of noise:
Listen carefully for the noise and try to identify its characteristics. Is it a shrill scream, a knock, or a scraping sound? Different types of noise can indicate different problems.
2.Check cavitation:
Cavitation is a common problem with piston pumps and produces significant noise. Cavitation occurs when not enough fluid enters the pump, leading to the formation and rupture of air bubbles. Check the condition of the inlet, such as the primary strainer and filter, and make sure they are not clogged.
3.Check the plunger and seal:
Inspect the plunger and seals for any signs of damage or wear. Worn seals or damaged plungers can lead to increased noise. Replace any faulty components.
4.Verify lubrication:
Insufficient lubrication can cause friction and cause abnormal noise. Check the lubrication system to make sure it provides enough lubricant for the moving parts.
5.Check the valve:
Check that the suction and discharge valves are working properly. Jammed, damaged, or improperly sealed valves can cause noise problems. Clean or replace the valve as needed.
6.Check the alignment:
Misalignment of pump parts can cause noise. Make sure the pump and motor are properly aligned. Misalignment leads to increased wear and tear on individual parts.
7.Check bolts and fasteners for looseness:
Vibrations caused by loose bolts and fasteners can create noise. Check that all bolts and fasteners on the pump head are tightened and secure the loose parts.
8.Monitoring the liquid level:
Check the liquid level in the pump. Insufficient liquid levels can lead to increased friction and noise. Top up the liquid to the recommended level.

9.Refer to the manufacturer's guide:
Refer to the manufacturer's guide and maintenance manual for your specific pump model. It may provide specific troubleshooting steps and maintenance procedures.
10.Seek professional help:
If you are unable to identify or resolve the issue, you may need to consult a professional pump technician or pump manufacturer for further assistance.
11.Check for contaminants:
Contaminants in the pump system create noise. Check for any foreign particles or debris that may have entered the pump. Clean the system thoroughly and consider installing additional filters if necessary.
12.Evaluate the pump speed:
Check that the pump is running at the correct speed. Running the pump at a speed outside of the recommended range can cause problems, including unusual noise. Verify the pump speed and adjust as needed.
13.Check the power supply:
Make sure the pump's power supply is stable and meets the manufacturer's specifications. Voltage fluctuations or insufficient power can affect the performance of the pump and produce abnormal noise.
14.Check the drive mechanism:
If the pump is belt-driven, check that the belt is worn, tensioned, and properly aligned. Loose or damaged belts can make noise. Tension or replace the belt as needed.
15.Perform pump stroke adjustment:
Incorrect pump stroke settings can cause noise problems. Check the pump stroke length and adjust it according to the manufacturer's recommendations.
16.Review of operating conditions:
Evaluate the pump's operating conditions, including temperature and pressure. Running the pump outside of the specified range can cause noise and premature wear. Make sure the pump is operating within the recommended parameters.
17.Consider vibration isolation:
Excessive vibration amplifies noise. Consider using vibration isolation brackets or pads to reduce vibration and minimize noise propagation to surrounding structures.
18.Recording and monitoring changes:
Record the changes made and monitor the pump's performance over time. Document any improvements or recurring issues. This information can be very valuable for troubleshooting and future maintenance.
19.Training & Awareness:
Ensure that the personnel who operate and maintain the pump are adequately trained. Knowing the right procedures and reporting any anomalous observations in a timely manner can help prevent and resolve issues early.
20.View the maintenance plan:
Regular maintenance is essential for the proper functioning of the pump. Check the manufacturer's listed maintenance schedule and follow it strictly. This includes routine inspections, lubrication, and component replacement.
If, after following these steps, the abnormal noise persists, or you are unsure of the cause, it is recommended to contact the pump manufacturer or a qualified pump service professional for further diagnosis and assistance. Timely resolution of the problem can prevent further damage and downtime.
