This pump is perfect for the EVS vacuum press kit and is suitable for vacuum bags as large as 4x15. You'll find that it generates a very powerful vacuum so it can be used for bending/laminating veneer over odd shaped forms. These units are also superb for bench top vacuum clamping.
Optional Mounting Screws
The mounting screw option (above) includes four 6mm x 1mm x 25mm machine screws for mounting the pump to your carrier.
This pump draw 12 amps at start up. A relay is required if you are using this vacuum pump on an EVS vacuum press system.
How does the 5.3 CFM differ from the 5 CFM pump?
The performance is almost identical but the price and weight difference of each pump are notable. The 5.3 CFM pump is considerably more affordable but it weighs more, has a shorter warranty, and requires a relay to power the EVS vacuum press system. Keep in mind that both of these pumps are excellent for use with the EVS vacuum press kit.

What is the warranty on this pump?
VeneerSupplies.com warrants this pump to be free of defects in manufacturing and materials for a period of 90 days from the date of purchase when purchased with and used with a VeneerSupplies.com vacuum press kit. No warranty is provided for vacuum pumps that are ordered without a VeneerSupplies.com vacuum press kit.
Can this pump be used for vacuum chucking?
There is no safe way to answer this question. More information needs to be provided. You would need to know three things...
With these bits of information, you can calculate a number that will help you determine if the pump is safe to use for chucking. Continue on to the next question.
How much clamping force will the pump create for vacuum chucking?
This is based on a calculation using the maximum sustainable vacuum level and the surface area where the project is attached to the chuck. A smaller attachment area means less clamping/chucking force. A large industrial pump capable of pulling a very high vacuum may not be suitable for chucking if the vacuum surface area of the project is small. You have to calculate the vacuum surface area on your project first. Then determine what amount of vacuum you are capable of applying to the project. With this information, you can determine the total clamping force on the project and consider whether or not it is enough to safely hold your project while it is being turned. Here is the method for calculating the clamping force.
What if the chucking project is porous? How do I determine if this pump is suitable?
Unfortunately, there is no way to determine this without actually placing the project on a vacuum chuck. You would need to determine the actual maximum sustainable vacuum and this will vary across each project you try out depending on the size and porosity of the material.
What pump do you recommend for vacuum chucking?
I can only suggest one thing... the bigger, the better. Several of our customers are using 3 CFM vacuum sources for chucking but most are opting for 5 CFM vacuum sources.
What is the size of the pump?
The approximate measurements are shown below.
Review by Christian D. Smith
I think this is an incredible price for a pump with more than 5 CFM of vacuum delivery. It appears to be well built with quality materials. I'm using this for vacuum chucking so I didn't need all of the other parts that are sold here. The vacuum filter was the only other things I ordered and it is also a very well made piece. Joe shipped my order about 12 hours after I ordered it and it arrived two days later by UPS.
Review by Gabe T. Coleman
This is a very heavy duty vacuum pump. The size and weight alone speak volumes about the build quality. It is very quiet - especially once it reaches part vacuum. I'm using this pump for a 6x12 vacuum bag and it pulls the vacuum down in less than 3 minutes. I suspect the CFM rating is even higher than claimed here.
I bought it on a Sunday evening and by Monday afternoon, Joe sent me a tracking number. It arrived at my door on Wednesday. Communication from Joe and his company here is second to none. You just don't find this kind of customer service anymore. Couple this great service with the excellent prices and the quality products... and you get all you could ask for.
