These pumps are available locally and are new.

Anyone have experience with these pumps? Would they be suitable for composites? My parts are going to be in bag rather than a mold. Parts are roughly 5' long by 6" wide. 

Any help would be appreciated. 

Thanks

In my opinion both pumps are not ideal for composite work. Just get a cheap rotary vane pump. They are much cheaper, better suited for composite processes and will last virtually forever, membranes will not.
