What is the difference between 1 stage and 2 stage vacuum pumps?
The main difference between a 1 stage vacuum pump and 2 stage vacuum pump is their way of operating. Nonetheless, a single-stage vacuum pump’s work is to generate vacuums. On the flipping side, a second stage vacuum pump’s work is to clean the entire system of vacuum. As a result, the two-stage vacuum pump ensures a deeper vacuum level.
All in all, it is inevitable that a two-stage vacuum pump is better than a single-stage vacuum pump. Although a 1 stage vacuum pump does not perform less than expected, it is somewhere behind 2 stage pumps. So yeah, a double stage pump produces deeper vacuum levels than those one stage vacuum pumps.
Single-Stage vs. Two-Stage Vacuum Pumps: Which Is Better?
While judging the efficiency in single-stage vs two-stage vacuum pumps, two-stage pumps are quite better. The reason is, a two-stage vacuum pump produces deeper vacuums than a single-stage vacuum. But that does not mean single-stage vacuum pumps are inferior either.
If you see, a single-stage vacuum pump is not inferior either. It leaves no stone unturned in providing a moderate amount of vacuum levels. Those who bother with only sufficient cleaning can simply rely on single-stage vacuum pumps.
What is a 1 stage vacuum pump?
A single-stage vacuum pump is none other than a centrifugal pump. Generally, a single-stage vacuum comes with only one impeller. However, the highest lift is 125 meters. Also, a single-stage vacuum pump is easy to repair and offers large flows. Although this single-stage pump comes with a simple structure, it always maintains a stable performance.
With sliding blades, cylinders, and one pair of rotors, a single-stage pump performs amazingly. In the same way, it gives enough convenience to the rough vacuum levels.
Single Stage Vacuum Pumps: What Do You Need to Know?
Nonetheless, a single-stage pump tends to be lightweight within a small volume. Besides, the design of single stage vacuum produces fluid flow in times of driving by a motor.
Not only have that, but a single-stage vacuum pump also works by exhausting in the pump’s built-in chamber. Therefore, this vacuum pump smoothly separates oil from its pumped gas. And when the oil gets back to its actual place, the gaseous substances start to exhaust again.

When to Use a Single Stage Vacuum Pump
In many operations, we get to see lots of dirt and dust. Again, handling card boxes make us see different contaminants too. If you want to overcome these problems with a suitable substitute, a single-stage vacuum pump is a fine choice. Or if you see any rough vacuum levels, nothing can be better than a single-stage vacuum pump.
What is 2 stage vacuum pump?
Before we go through the actual comparison, let us know about the 2 stage pump precisely.
A dual-stage pump is a reliable vacuum pump that comes with two suction impellers. And these two impellers operate side by side at the same time. Again, while working with a two-stage pump, you have to decide whether you want more pressure or more volume. Just select your choice from its pump panel.
It would be great if you are comfortable with the pump’s transfer valve. Also, remember to make a selection between pressure and volume in times of using a 2 stage vacuum pump.
Two-Stage Vacuum Pumps: What Do You Need to Know?
Like single-stage vacuum pumps, two-stage vacuum pumps come with impellers. But the difference is, two-stage pumps have two suction impellers that operate side by side. Those who will be operating must choose between more pressure and volume. Well, you can find these options on the pump panel.
Dual-stage vacuum pumps or two-stage vacuum pumps are high in a mated vacuum and low in a vacuum. Mainly, the low vacuum stage plays a crucial role in improving the performance of your vacuum pump. The reason is, the low vacuum stage in a two-stage vacuum pump compresses the gas into atmospheric pressure.
Contrastingly, a two-stage vacuum pump’s high vacuum stage amalgamates the process and sends it to the second stage.
Which Is the Best Two Stage Vacuum Pump for You?
As said before, the CFM of all two-stage vacuum pumps is not the same. Now then, two-stage pump products own 5 CFM, 2.5 CFM, 3 CFM, or even 9 CFM.
Autogen Vacuum Pump is one of the best two-stage vacuum pumps in the market. In this product, you will find numerous applications, like- food processing, milking cow, degassing wine, refrigerant recharging. However, this pump is available on Amazon in a good quantity.
