How To Maintain The Water Pump?

Table of Contents

If the water pump is used under the operating regulations, there are generally fewer failures within 2 years. But it must be maintained as required. Bison offers water pumps including diesel water pump and gasoline water pump. These pumps are used in many different systems, including water boosting, sewage treatment, and water transportation. Although water pumps have different uses, the maintenance of water pumps is similar. 

In this article, we will explore effective ways to maintain a water pump, keeping it in excellent working condition and preventing potential issues. Whether you have a residential well pump or an industrial centrifugal pump, these maintenance tips will help you extend its lifespan and maintain efficient operation.

How to check before the water pump works?

Regular inspections are vital for identifying any signs of wear or damage early on. Here’s what you should look for during a pump inspection:

  1. Check the foot bolts and coupling screws of the water pump and power machine. If they are loose or fall off, tighten them.
  2. Rotate the coupling or pulley to check whether the rotating part of the pump is flexible. At this time, you can also observe whether there are any foreign objects falling into the pump.
  3. Check whether the lubricating oil in the bearing is clean and appropriate
  4. Check the physical condition of the system, including impellers, seals, bearings, valves, etc.
  5. Check the protective measures such as electrical components, fuses, etc.

Although we recommend a professional pump expert to carry out comprehensive maintenance. But you can do some things to ensure the pump working efficiently and reduce the risk of failure. Early detection of potential problems through pump maintenance can help prevent costly repairs or replacements. Regular maintenance keeps pumps running efficiently, saving energy and reducing operating costs, while extending pump life and preventing premature failure. diesel water pump

Cleaning the Pump

Over time, debris and sediment can accumulate in the pump, leading to reduced efficiency. Cleaning the pump regularly is crucial for optimal performance. Follow these steps to clean your water pump:

  1. Disconnect the power supply to the pump.
  2. Remove the pump housing and impeller.
  3. Use a soft brush or cloth to clean the impeller, housing, and other components. You can use gasoline to clean carburettor and gasoline filter element.
  4. Remove any debris or sediment that has accumulated.
  5. Rinse the components with clean water.
  6. Reassemble the pump and ensure a secure fit.


Proper lubrication is necessary to minimize friction and prevent premature wear of moving parts. Apply lubricant to the pump bearings, shaft, and other moving parts as specified.

After using the four-stroke gasoline or diesel water pump for 40-50 hours, the crankcase oil should be replaced. If the pump is not used for a long time, it can be started and run for 5-10 minutes every 20-30 days. This will lubricate the transmission components and prevent corrosion.

Monitor Pump Performance

Monitoring the performance of your water pump allows you to detect any abnormalities or inefficiencies promptly. If you notice any of these signs, it’s essential to investigate and address the issue promptly to prevent further damage. Keep an eye out for the following indicators:

  • Changes in water pressure or flow rate
  • Unusual noises or vibrations
  • Increased energy consumption

Maintain a Clean and Adequate Water Supply

The quality and source of the water supplied to the pump can significantly impact its performance and longevity. It’s important to:

  • Ensure the water supply is clean and free from debris or contaminants.
  • Install appropriate filters or strainers to prevent debris from entering the pump.
  • Regularly clean or replace filters as needed
  • After the water pump is used,  remove the water pipes and fittings in time. The remaining water inside the water pipes and the pump should be drained.


Proper maintenance is key to ensuring the longevity and efficient operation of your water pump. By regularly inspecting, cleaning, lubricating, and monitoring its performance, you can prevent issues, minimize downtime, and extend the lifespan of your pump. Remember to follow the manufacturer’s guidelines and seek professional assistance when needed. By taking care of your water pump, you can enjoy reliable and uninterrupted water supply for years to come.
