6 Ways To Combat Corrosion And Make Your Pumps Last Longer

Are you often worried about pump wear and wonder how to extend its life? The key lies in anti-corrosion! This not only reduces wear, but also protects the pumped fluid.

When buying a new pump, choose one that is corrosion-resistant and has a low overall cost. If corrosion and erosion occur during the operation of the pump, the pump will age rapidly and its efficiency will plummet. Then operating costs will soar, production will decrease, and maintenance downtime will increase significantly.

Next, South Pump will show you six ways to prevent and solve pump corrosion.

1. Select the right pump

In industrial production, when encountering corrosive fluids such as acid and wastewater, it is crucial to choose a pump. If you choose the wrong one, the pump may be scrapped soon. In the long run, it is both expensive and time-consuming.

Plastics and metals are commonly used materials for pumping. They must be carefully selected according to the characteristics of the liquid. If you are really unsure, you may as well ask professionals for help. Those that are recognized by everyone are likely to be reliable.

Moreover, selecting pumps according to needs is the key to preventing cavitation. Pay attention to capacity and head. Make NPSHa higher than NPSHr to ensure the stable operation of the centrifugal pump.

2. Choose the Correct Material for the Pump

Pump manufacturers have to find ways to reduce corrosion. The key is to choose the right base material for the pump structure.

If you want to use carbon steel or cast iron for cost reasons. You must first accurately estimate the corrosion rate. Based on this, calculate the pump life and plan maintenance costs. If the rate is high, you have to upgrade to stainless steel. If the cost is high, use customized high-grade coatings.

It is worth noting that if you choose the wrong grade of stainless steel or use it improperly. Then, particles, chlorine, and stagnant conditions in the liquid can cause it to corrode. It is not as durable as carbon steel. There is a risk of cavitation, and customized coatings can help.

In short, only by choosing the right materials can you reduce corrosion and erosion problems.

3. Protective Coating

Want industrial pumps to be more durable and perform better? Advanced coating technology can help! Although choosing the right materials is important, coatings are a good helper to extend life. Series of self-priming pumps can be coated in a variety of ways. You need to discuss with engineers to see if it can really increase efficiency and save money.

Polymer coatings such as melt-bonded epoxy resins. When applied to pump parts, they can prevent corrosion and erosion and improve hydraulic performance.

There are also carbide coatings containing tungsten, nickel, etc., which can be customized to meet needs.

In addition, polymer coatings are suitable for low-flow clean water. High-flow pumps have to be coated in selected places. The hard layer is sprayed, and each has its own requirements. Thermal spraying and CVD processes are also different. If you want to know more, you can contact us at South Pump. We have professionals to answer your questions.

4. Maintaining Legacy Equipment

Don’t be in a hurry to get rid of the old pumps at home. Renovate them to keep them going!

The current coating technology is super powerful and is used on traditional and old equipment. That is to put a “protective armor” on the pump and increase its lifespan. As part of a refurbishment program, equipment performance and reliability can be significantly improved once a new coating is applied.

If you plan to replace your pump with a new one, you must seize the opportunity. Not only does the substrate need to be selected, but it must also be paired with the best coating system. The durability of such a pump is beyond words.

You can also communicate more with experienced engineers. Fully understand needs and use various information skillfully. Give an old pump a new look. Extending service life and improving performance are easy.

Combat- pump Corrosion

5. Run your pumps slower

Want to make your electric centrifugal pumps last longer? Try to slow down the priming pumps! When the liquid for pumping runs slower, the corrosion caused by abrasive fluids will be greatly reduced.

Generally speaking, pump manufacturers will recommend that the speed be controlled below half of the capacity. Of course, it depends on the nature of the fluid in the pump. This is like running slower, which consumes less energy. The same is true for pumps, which can last longer.

Also, don’t forget to give the magnetic driven pump a “physical examination” regularly to test its condition. And it’s best to simulate the actual operating conditions of the pump to test it. This way the results will be accurate and you can better protect your pump.

The external parts of the pump must also be well protected, and you can’t just focus on the inside.

6. Protect the external parts of you pump

Those exposed surfaces, although not directly in contact with the pumped fluid. But they are also easily damaged. If the pump is immersed in water, such as when pumping water from the sea.

The salt water is very strong and can easily corrode the parts. At this time, we can apply a coating to the outer surface. The most commonly used is paint, which is like a protective film that can keep water and other dirt out. Less damage to the external parts of the pump will make the pump work better. Isn’t it simple?

 

In short, whether it is manufacturing, refinery, or papermaking, wastewater treatment, energy and other industrial fields, pumps are the “greatest contributors” to efficient operation. Liquid flow is inseparable from them.

If you want to reduce factory downtime and reduce costs, you have to improve the reliability and efficiency of pumps. Don’t worry about corrosion problems. The sooner you prevent them, the better. Find a reliable pump manufacturer and talk about your needs with an open mind. Contact South Pump to start a worry-free pump experience.
