As the head of an industrial or commercial company that uses centrifugal pumps, you know that these sturdy devices won’t often break down or stop working. However, to keep your pumps in good repair, safeguard yourself and your employees, and prevent lost work time and revenue, you need to take extra measures to ensure your centrifugal pumps always work properly.

Below, we’ve listed several maintenance tips you can employ on a daily or weekly basis to keep your centrifugal pumps in top condition. We’ll also talk about different repairs your pumps may need if they break down or malfunction. Read on to learn what you can do to ensure your pumps’ performance.

Maintenance Tips

Your business-and your employees’ livelihood-depends entirely on a functioning centrifugal pump. Without a properly working pump, you can’t complete your work. Instead of letting an issue arise, use the following maintenance tips to keep your centrifugal pumps functioning efficiently.

Your best tool in maintaining your centrifugal pumps is to inspect them frequently. If you check the pump and its components regularly, you reduce the risk of breakdowns and inadequate pumping capacity.

Before you inspect the pump, review the operator’s manual so you are familiar with every aspect of the device. Use the following schedule to prevent breakdowns:

  • Annual maintenance. Each year, test the electrical components of your pump. Test all the alarms to ensure they work properly and can alert you and your employees of an issue. Also, change the oil in the seal.
  • Semiannual maintenance. Even though you’ll change the oil each year, you should check the oil levels twice a year at least to make sure the pump has enough fluid in the seal.
  • Monthly maintenance. Look at the suction valves, gate valves, and butterfly valves. Keep an eye out for leaks and discharge.
  • Weekly maintenance. Make a record of different readings, such as amp readings, meter readings, discharge readings, and suction gauge readings. If the numbers are too high, you may need to repair or replace a part to prevent a breakdown.

If you don’t feel comfortable inspecting these parts of the pump, have a professional do the job for you.

Some other maintenance tips are to make sure that the seals are lubricated and that the pump is never empty or low of liquid. If the pump dries out, it could malfunction.

Common Issues

Sometimes, despite your best efforts to monitor, clean, and maintain your centrifugal pumps, these pieces of equipment may break down or stop working completely. In the event of a breakdown or malfunction, you’ll need an authorized repair company to fix the any of these problem.

Cracked or Fractured Seal Face

The seal face, or mechanical seal, prevents a centrifugal pump from leaking. When the seal has fractures and cracks in it, the liquid in the pump can leak out. Usually, impact or thermal shock cause this kind of damage. A professional can replace the seal and advise you to eliminate the source of the shock or impact to prevent future damage.

Uneven Wear Track

If the seal face is tightened too much on the pump, the track between the two can become uneven. This damage also occurs when there is too much pressure or clamping and high temperatures that work on the seal. An uneven wear track can increase the risk for leaks and similar issues.

Grooved Seal Face

If you notice this kind of damage, the seal face isn’t properly lubricated. Additionally, the liquid inside the pump may contain abrasive materials that can embed in the seal and forms grooves in it. A professional can flush the seal and lubricate it to prevent this issue. He or she may also recommend a seal that can withstand corrosive and abrasive materials.

Failed or Minimal Liquid Delivery

As previously mentioned, if your pump doesn’t contain enough liquid, it can shut down or stop working. A professional can inspect different components of your pump, like the discharge system or the impeller, to discover why the flow is so low. Then, he or she will repair the issue so your pump allows liquid to flow fully.
