Hi all,




I've been doing a lot of wet lay recently and it can be a lot of effort per part to ensure a pinhole free finish. I am looking to start resin infusing and wondered if anyone has any experience with the following pump:

Reason I ask is because its cheap! Will it be up to the job? the parts I am making are smaller than a dinner plate.




Also, is it risky to infuse without a catch pot/vacuum chamber if I leave enough silicone hosing on the pump side?




Best Regards,




James

Just seen its single stage (not sure what this means!), 




would this dual stage be a better option:

For Resin Infusion you need a pump that can achieve 99.99% vacuum. The first pump achieves 95% vacuum so is not good enough.

The second pump achieves plenty of vacuum and is also a very high flowing pump so will work fine on very large components or multiple bags.

Thank you for the info Warren, much appreciated.

Just for future info,




I bought the second pump (£125) - what a bargain!




Works flawlessly, mint condition, just didn't have the original box. it also came with easy composites tape around the box so must have been from you guys at some point




£200 ish saved for not having a cardboard box ! not bad at all...
