How to Select a Hydraulic Pump For Your Business (and How to Maintain It)

Hydraulic pumps are used mostly in construction and in agriculture. 

But if your business has anything to do with manufacturing, marine, mining, aerospace, forestry, oil/gas, you’re in the automotive industry, energy, railways, etc., etc. – then chances are, you’re also dependent on hydraulic pumps.

And while hydraulic pumps ARE amazing pieces of machinery, they aren’t THAT fun once they break. This mostly has to do with how hard it can be to get a new (or replacement) part in order to fix it.

In this article, we’ll provide you with a (somewhat) detailed explanation of the operating principles and some factors that have a massive impact on which the right hydraulic pump is for a specific system.

What Are Hydraulic Pumps And What Types Are There?

To start with, what exactly are hydraulic pumps? 

Hydraulic pumps turn mechanical energy into fluid flow by creating a vacuum. The pump represents the heart of the power machinery, as it supplies the flow that makes the work possible. Pressure is created when there is resistance applied to the fluid movement within the system.

There are several hydraulic pumps, each designed to match the system conditions. 

The most common hydraulic ones are gear, vane, and piston pumps. Gear pumps are simple and are used for lower-pressure work, mostly in agriculture. Vane pumps usually have better efficiency, are not as loud as gear pumps, and are mostly used in controlled industrial environments. 

On the other hand, you’ve got piston pumps, which also have the highest efficiency. This means they can handle super high pressures (unlike the other two). Piston pumps are the best option for complex machineries that require better performance and high-pressure tasks. 

Since hydraulic pumps are most commonly used in agriculture, construction, and industrial equipment in tractors, forklifts, and excavators, they are essential in order to lift, move, and control heavy-duty tasks. 

Replacement Solutions

Many hydraulic pumps have been used for years within old systems and will eventually wear out. 

When that happens, the pump needs to be replaced, but since the systems are old, there might be a possibility that the same pump is extremely hard to find or is no longer produced. 

This is why it’s best to partner up with a business like Char Lynn pumps in Arkansas or any other company that specializes in hydraulic pump replacement parts and repairs. Whoever you choose, just make sure they’re shipping to you, or that you can collect the parts in person. 

If the business also manufactures the parts as per OEM specifications and has a large inventory, that’s better because it’s more likely they’ll be able to maintain/fix any issues that might come up with your hydraulic pumps, plus if the pump matches the system, it can be integrated into the system without major changes.

If you don’t live nearby, make sure to find a similar one that also specializes in replacements.

What Are the Key Factors When Choosing the Right Pump?

When choosing hydraulic pumps, the main focus should be on how fast the moving parts are and how much load the system can handle.

When that is determined, you also must consider the fluid type because not every fluid is compatible with the pump system. Moreover, another important factor is the temperature range since it affects the viscosity of the fluid and therefore has an impact on pump efficiency, potential damage, and the service life of the pump overall.

It can also cause the material to harden or soften and increase the risk of cavitation.

How to Prevent Damage With Proper Maintenance?

Regarding the fact that some design systems are old and hard to replace, it’s of great importance to maintain every part, especially the pump, since it represents the heart of the system. 

Meaning, the fluid has to be analyzed every once in a while, filters need to be changed regularly, and you need to make sure there are no funny noises or vibrations. If there is, it means something is wrong, and the warning signs were not recognized on time. This is why in such industries that work with complex machinery, there has to be a highly educated person responsible for supervising the work thoroughly. 

Regular checks and proper care of the whole machinery, especially the pump, will make a huge difference in the performance of the whole system. 

Conclusion

To conclude, hydraulic pumps are fundamental pieces of equipment essential for providing energy to the complex systems in agriculture, construction, and many other industries. 

By understanding how the pump works and how to maintain it properly without damaging its components, engineers and company owners can ensure long-term efficiency of the machinery and prevent the costs of repair. Some of the factors that must be considered when choosing the right pump are fluid type, temperature range, and system capacity. 

If some components of the machinery are worn out, it’s best to find a company that specializes in repairing and replacing hydraulic components.
