Types Of Grease Gun
We can classify the grease guns into 3 major categories depending on how they’re powered: hand, battery, and pneumatic/air powered.
The hand-powered models can further be subdivided into pistol grip, press, and lever style guns.
Let’s get a closer look at each type of grease guns:
>Hand powered grease guns (with trigger mechanism)
Also referred to as pistol type grease gun (due to its pistol grip design), this gun style forces the grease out by back pressure that’s built up by the hand cranking its trigger mechanism.
The pressure is applied to a spring just behind the grease, which then forces the grease through the aperture/nipple and into the precise area where you want to apply it. These guns can deliver a pressure of around 3,500 to 10,000 psi, depending on the model.
A typical model can deliver as much as 0.86g of lubricant per stroke.
The biggest advantage of using this type of grease gun is that you can operate it with one hand, leaving the other one free to do other supportive tasks. Both lefties and right-handed users can operate it. And it comes in different sizes to fit different hand sizes.
>Hand powered grease guns (with press mechanism)
Also known as manual lever grease guns, these guns are also manually operated…but in a different manner. That is, you push on the butt of the gun by the mechanism of sliding a piston through the gun body. This will help built up back pressure which will then force the grease/lubricant out of the gun through the aperture.
Depending on which model you buy, you can find these grease guns with pressure ranging from 3,500 to 10,000 psi.
However, this type of hand pump grease gun isn’t the easiest to use.
>Battery powered grease guns
Grease guns that are powered by batteries are also referred to as cordless grease guns. These guns are loved because they eliminate the cord which can turn out to be a nuisance when using the grease gun.
Because of their power source, these models also save you from manually putting a lot of pressure to force out the lubricant. The guns also have the benefits of portability, where you can carry and use them to any place you want.
Most of the cordless grease guns you’ll find on the market today are rated between 6,000 and 10,000 psi.
>Pneumatic/Air powered grease guns
As the name suggests, grease guns that fall under this category are powered by air. In other words, they rely on compressed air which is fed to them via a hose. The compressed air then creates a pressure that forces the lubricant out so that you can direct it to where you want to apply it.
Given the fact that these guns need to be attached to the hose during operation, they can become inconvenient to some users.
Besides, they’re costly and are extremely powerful that they can end up blowing a bearing on the smaller machinery components. For this reason, pneumatic guns are confined to heavy-duty commercial and industrial applications.
How To Buy A Grease Gun?
Let’s face it… when shopping around for a grease gun, your end goal is to find the best grease gun that allows you to easily apply the right amount of grease or any other lubricant on your specific type of machinery.
That being said, you’ll need to make the following considerations to ensure you find a model that matches your unique needs…
## Types of Grease Gun
One of the most important decisions you need to make when buying a grease gun is the type to choose.
As we discussed a bit earlier, the grease guns can be classified into various styles, depending on how they’re powered.
Let’s have a quick recap of these guns:
Lever: this is the cheapest and most popular type of grease on the market. It simply enables you to create pressure by pulling a lever. It’s suitable for light duty applications.
Pistol grip: easy to handle with only one hand. Available for both left- and right-handed users.
Cordless: powered by batteries. Portable and suitable for people who want a grease gun they can carry with them everywhere.
Hand pump: for this gun to apply the lubricant, your hand will need to do some pumping action
Pneumatic: the most powerful type of grease gun of all the above. Great for heavy-duty commercial and industrial applications.
## Ease of Use
The next thing you need to look for in a grease gun is how easy it is to use. You don’t want to buy a model that’s too complicated that it takes you forever to understand how it works.
The grease gun should easy to handle for you.
Most of the models we’ve discussed above also come with an extra-long flexible hose to make it easy for you to lubricate the hard to reach grease fittings, LED lights for easy greasing in low light situations, anti-slip rubber sleeve along the barrel for easy handling and cartridge changes, etc.
All these features make a grease gun easy to use for you.
## Amount of Lubrication
It’s also crucial that you know the quantity of lubricant you need to apply before buying a grease gun. Of course, this will depend on the type of machinery you intend to lubricate.
If your machinery needs high amounts of the lubricant for smooth running, then you should go for the high-volume grease guns. These models are able to dispense a high amount of grease per stroke for efficient lubrication of your machine moving parts.
For light duty applications, say around your home, then a standard grease gun with smaller capacity is sure to fit your needs.
Now that a grease gun is just another mechanical equipment that can break down unexpectedly, it’s also good to ensure you get one that comes with an extensive manufacturer warranty.
This way, you’ll have some peace of mind knowing that in case the tool fails, the manufacturer will repair or replace it for you without incurring any extra costs.
