Buying Considerations of The Best Vacuum Pump
Purpose of use
Before buying a vacuum pump, you need to determine what you want to use it for. For home use, a moderate vacuum pump will serve you since you will probably use it less than 6 times a year.
But if you need the pump for industrial use, you should lookout for a high-efficiency vacuum pump. You don’t want to start regretting buying a product that broke down just a few days or weeks of use.
If it is for industrial use, you should go for vacuum pumps that can work for long hours without burning out.
This is another thing to bear in mind. Many of us would rather pay a little extra to get a vacuum pump that will last us for the long haul than settle for a cheaper product that may not last.
This is not to say that price is a determinant of a good product, however, if after going through a review and you like what you see and it is a little higher than what you had planned to spend, it’s better to save up and get the one that will save you money in the long haul.
What your vacuum pump is made of is another consideration here. It is always better to go for alloy aluminum housing or casing as they protect your device from bugs, dirt, and debris from eating into its lifeline.
Ease of use
Some vacuum pumps come with the ON/OFF switch and a direct drive to make starting the pump an easy task. Apart from that, where the oil drain port and oil filling port are located also helps in determining how easy a vacuum pump is to use.
If you can get the one with an oil-viewing glass, it makes it even easier to check your oil and know when to top or drain. And refilling your pump at the right time is key to prolonging its lifeline. While at it, see if you can find the one with a good handle for easy carriage.
FAQs About Vacuum Pumps
What is the best vacuum pump?
There is no clear answer to this as what is regarded as the best vacuum pump for you might not be for the next person. To get the best, go through the features of the product you have in mind to see if it will meet up with what you intend to use it for and you are good to go.
What does CFM mean?
CFM simply means the Cubic Feet per Minute and is what is used in measuring the speed of air displacement for every minute the pump is on and running.
If your vacuum pump is bigger and stronger, the CFM will be faster than smaller pumps. You will find CFM mostly in rotary vane pumps and is used mainly for HVAC maintenance.
What does Stage 2 stand for in a vacuum pump?
Stage 2 means that the vacuum pump has a rotary vane design with two stages. The second stage which is also known as the exhaust stage is where the emphasis lies.
It is this stage that speeds up the performance of the vacuum pump. It is also what helps the pump to move from 150 microns to 1 in a short time. Vacuum pump with a single-stage takes longer to move to 15 microns and is best for home or personal use.
When is the right time to change my vacuum pump oil?
The standard recommendation is to change your oil after 500 to 750 hours of use. However, it may be difficult to keep a tab of the number of hours the pump has been used.
The best way to determine when your oil should be changed is when it has become misty or considerably dirty. If the oil is highly contaminated and your vacuum pump is a 2 stage pump, it will have more effect on it than on a single stage vacuum pump.
