Is this a good pump for the price or should I look somewhere else? And if so where can I look? $309.00
What is the cost and spec’s?
you can usually find the pumps evan sells on ebay brand new.

A Great Starter Pump!
Simple and Immediate Use
Rated for continuous operation, this oilless pump is wired for immediate use in a standard 110 outlet. Supplied with a barb fitting which ensures secure coupling to #893 vacuum tubing. The only assembly required is the attachment of feet which are also supplied with the pump. Suitable for parts up to 30-40 sq. ft.
1/16 HP, 24" Hg, .5 CFM Diaphragm Pump comes with Unlimited One Year Warranty.
Qty: 888-A Each ($309.00)
Now this is only my opinion, but I think that you can find better pumps for less. For example, either the Robinair or Ritchie Yellow Jacket pumps will pull a high vacuum (30" or very close) and can be had new for about this price and less used. One caution on the used ones in that these pumps are essentially designed as disposable units and there are limited if any rebuild supplies. However, that said, unless you are putting them through extreme duty or just not changing the oil, they should last you a long time. I personally use a couple pumps in series with a vacuum reservoir and a resin trap where the high vacuum pump is on during infusion and the low vacuum is on during the cure cycle.
How about this one, is this good price? I would be using it for mostly small to medium sized jobs. nothing bigger than motorcycle fairings.
It’s up to $158.00
That would probably work well. New I think they go for $300 to $350 so judge the pricing accordingly for a used one.
The robinair is a good cheap pump that you can get for infusion. If you’re just doing vac bagging then the first pump you posted will do also.

That pump that you are looking at is a Gast MOA series pump…they Max out @ 24" (and if it’s used…it probably isn’t near 24")
So that would be a dedicated Vacuum bag pump (no infusion work there)
If it is used…the MOA head/valve rebuild kits are about $20 CDN from Gast directly (cheaper than the Piston rebuild kits for sure)
What do you guys think of this pump?
And these are the specs: In other words the higher the CFM # the better or what? What am I looking for, what makes a good pump for dry and wet applications.

I think that is the same pump as above only the 15600 is 6 cfm (I think?). As Evan said, this will work well for infusion.
That’s the 15500…it’s the 4 CFM version of the 15600…good for Infusion work. CFM isn’t really important unless you are doing a large casting.
It will pull a 29.98" for sure if it’s new. Also take a look at the Robinair “Vacumaster” line (that one is the Cool-Tech line). They are smaller and cheaper than the Cool-Techs, but they still pull 50 and 40 microns depending on the model.
here is a link to the 15600 for $250 -
Now, I have not bought anything from them before and I don’t think Evan minds since ops are closed for now.
so the 6cfm robanair pumps would be ideal for infusion and/or bagging???
Any of the Robinair 15xxx series pumps will get you the deep vacuum you need. the 6 CFM pump will just get there the fastest…but if you’re only making beer coasters…you really don’t need a pump that big (think about the volume of of the mold)
But if you’re making like hoods and fenders…Go Big or Go Home
Okay is this over kill:
Specifications

Intake Fitting…1/4" and 1/2" MFL
Oil Capacity…16.5 oz. (488 ml)

Dimensions…10" H x 5-5/8" W x 16" L
…(27.2 cm x 14.2 cm x 41.9 cm)
Mayybe if you’re doing an infusion 40’ boat…might be a bit on the overkill side for normal stuff.
what size vacuum pump would be needed for infusion on smaller parts…say less than a square foot?
you wouldnt beleive how hard it is to buy a vacuum pump in the UK,its either ebay or £1000000000000000 industrial stuff
