Replacement Air Compressor Pump Buying Guide

Are you planning to buy a new replacement air compressor pump? If the answer is YES, this buying guide is written for you. Make sure you check it out before making the final purchase.

  • The Compatibility Compared to the Old One

Now, in case you were looking for something totally out of scratch, your options could be more random undoubtedly; but as the word ‘replacement’ adds up, certain conditions do have to get considered. And the topmost condition, in that case, happens to be whether your replacement pump is going to be compatible compared to the old one or not.

Your replacement air compressor pump has to be up the machine’s standard that you’ll be using it with. In many cases, most air compressor pumps have to be replaced with a pump of the same company to deliver the same output. In order to make it more convenient for customers, some manufacturers do put out some universal-fit designs, but still, your old pump can be out of the range.

Besides, the HP, CFM, PSI have to match up. You can’t replace an oil-lubricated pump with a battery-driven one. So, there are more than one aspect to consider before one can settle on their replacement air compressor pump.

  • Measurement Units are Essential

In the purchase of a replacement air compressor pump, knowing the measurement units are very important. The constant units that are considered to measure a pump’s performance quality are usually PSI, CFM, HP, and in many cases, rph.

These units let you know how much oil or electric power the machine is going to cost you at one cycle of air compression, or how much output it’s capable of delivering. Using these measures, you can easily find out whether the replacement is going to match the system or not.

  • Durability Must Be Prioritized

While choosing a replacement air compressor, you must definitely check out the materials used in its structuring first. The materials tell a lot about the product’s durability.

Battery-driven pumps are usually made of light materials, whereas because of the oil’s nature, going with tough metal is necessary while constructing oil-lubricated pumps. Usually, the iron cast is used to build the crankcase of the pump, so that it doesn’t easily fall apart. Stainless steel is a popular choice for valves inside, using such material also eliminates the possibility of the motor getting all rusty.

So, during the purchase of oil-lubricated motors, most definitely try to choose an iron cast body with rust-proof inside. For battery-driven ones, lighter the better.

  • Single-stage or Double-stage Compressor

An air compressor pump being single-stage or double-stage doesn’t make it more or less better of a product. This feature just defines the capacity of a pump to pressurize the air.

In a single-stage pump, the air gets directly compressed; whereas in a double-stage pump, the air has to go through cylinders before being completely compressed. The double-stage process is required for more intense pressure. However, intense air pressure is not always necessary in the job. Thus, the double-stage structure isn’t always mandatory either. In fact, using a single-stage pump is more effective in most cases as it costs less energy and time to compress air.

  • Learn Your Priority

Air compressor pump can come handy for various purposes, ranging from dental treatment to heavy industrial activities. Depending on the demand of the sectors, the requirement for compression pressure varies, and so do the features of the pumps. So be cautious about that while going through all the options.

FAQs About Replacement Air Compressor Pump

In this section, we are going to answer some of the most frequently asked questions by air compressor pump users. Do you have a question? Check them out, maybe we have already answered yours.

1. What is PSI?

Ans: PSI is the abbreviated form of the phrase “Pounds per Square Inch”. It’s a unit for measuring pressure; which makes it an essential measuring unit when it comes to air compressor pumps since those are particularly all about pressuring and compressing air.

2. What is CFM?

Ans: CFM is the abbreviated form that stands for Cubic Feet per Minute. It is a fundamental measuring unit in the work of air compression as it’s used to measure the flow in which a certain amount of air gets compressed at a time.

3. What is HP?

Ans: It is a unit that tells you how much work a machine is capable of doing. HP stands for Horse Power.

4. Why does HP matter?

Ans: The job of air compressing varies from motor to motor given how they’re engineered to get the job done. When you’re purchasing, you probably already have decided in your mind what type of performance you want from your compressor pump. The unit of HP lets you know the capability the motor of your choice has, and it also allows you to compare a certain model with other counterparts before making the final choice.

5. What is a Single-stage Compressor?

Ans: In a single-stage compressor, the air gets compressed once inside the motor for delivering the desired output.

6. Why do most air compression pumps rely on oil instead of batteries for running?

Ans: Thanks to modern technology, we own the privilege of running motors on both oil and electric power, which is equally true for current air compressor pumps as oil. Batter-driven engines and oil-fueled ones, both have their fair share of pros and cons.

While battery-driven pumps tend to be lighter than iron cast ones, and also compatible for delivering more pressure with a particular PSI; they certainly aren’t as long-lasting as oil-fueled pumps. Moreover, battery-driven pumps happen to make more irritating noise because of their structure.

7. What is crankcase?

Ans: It is simply a case intended for covering the body of a crankshaft. The crankshaft is an attribute of internal combustion engines, and air compressor motors are one of that kind. Besides, engines running on oil has one more duty for the case; most of the times, if a separate unit is not included, the crankcase is where the oil for compressing is stored.
