How To Maintain And Upkeep An Environmentally Friendly Horizontal Slurry Pump?

Sep 08, 2025

The maintenance and upkeep of horizontal slurry pumps are key to ensuring their efficient and stable operation. The following are some specific maintenance and upkeep measures:
1, Daily operation inspection
1. Inspection of connecting components:
Carefully check whether the bolts connecting the pump body, pipeline, motor, and other parts are tightened to prevent leakage or vibration caused by looseness.
Check the connection of the coupling to ensure its concentricity meets the requirements, in order to reduce bearing load and vibration noise.
2. Monitoring of operating parameters:
Real time monitoring of pump operating parameters such as flow rate, head, and current through instruments such as flow meters and pressure gauges to ensure that it operates within the design range.

If any abnormal changes are found, the machine should be stopped for inspection in a timely manner.
3. Vibration and noise monitoring:
During normal operation, the environmentally friendly horizontal slurry pump should have smooth vibration and low noise.
If there is increased vibration or abnormal noise, the machine should be stopped immediately for inspection and troubleshooting.
4. Leakage inspection:
Regularly inspect the pump body, pipeline connections, and seals for any slurry leakage.
For minor leaks, the tightness of the packing can be adjusted appropriately; If the leakage is severe, the machine must be shut down for inspection and repair.

2, Regular maintenance
1. Clean the pump body and pipelines:
After each shutdown, promptly clean the pump body and pipelines with clean water or suitable cleaning solution to prevent corrosion or blockage caused by residual slurry.
2. Maintenance of lubrication system:
Check if the oil level of the lubricating oil is within the specified range, ensuring that the oil quality is clean and free of impurities. For large slurry pumps, inspection can be carried out through the oil level observation window.
Regularly replace or replenish bearing grease to ensure that the bearings are in good lubrication condition. At the same time, clean the lubrication system to prevent impurities from entering.
3. Maintenance of sealing system:
Check if the sealing surface of the mechanical seal is clean and flat, and if there are any signs of damage to the sealing components. At the same time, check whether the tightness of the packing seal is appropriate to prevent leakage.
Maintain the good condition of the seals, regularly check the degree of wear and replace them in a timely manner. At the same time, adjust the pressure of the sealing device to ensure normal operation.
4. Maintenance of impellers and volutes:
The impeller and volute are key flow components of slurry pumps, which are susceptible to erosion and wear from slurry. Regularly open the pump casing and check the wear level of the impeller and volute.

For severely worn impellers and volutes, they should be replaced in a timely manner to ensure the performance and efficiency of the pump. At the same time, clean up the debris, sediment, etc. accumulated inside the impeller and volute.
5. Bearing maintenance:
Keep the bearings clean to prevent dust, impurities, etc. from entering the interior of the bearings and accelerating their wear. In daily maintenance, pay attention to cleaning the dust and debris around the bearing seat.
Regularly check the clearance and wear of bearings using professional tools. If the clearance increases or there are obvious signs of wear on the bearings, they should be replaced in a timely manner.
3, Other precautions
1. Use of backup pump: If you have a backup pump, it is best to rotate it regularly to reduce the burden on a single pump and avoid excessive wear and tear.
2. Preventing pump jamming: To reduce the risk of pump jamming, a filter screen can be installed at the inlet to effectively prevent impurities from entering the pump body and reduce the probability of pump jamming.
3. Electrical maintenance: Understand the power and control system of each pump motor to ensure its normal operation.

4. Reasonable load management: According to work requirements, control the working load of the pump reasonably to avoid prolonged high load work causing equipment overheating and shortened lifespan.
5. Safe operation: When cleaning, inspecting, or repairing, safety operating procedures should be strictly followed to ensure the safety of personnel and equipment.

The maintenance and upkeep of horizontal slurry pumps require comprehensive consideration of multiple aspects, including daily operation inspections, regular maintenance, and other precautions. Only by comprehensively and meticulously carrying out these tasks can we ensure the efficient and stable operation of the slurry pump, and extend its service life.
