I own a small fabrication shop, and we do a very wide range projects that include light production of out-of-autoclave prepreg parts, resin transfer molding, veneer laminating under vacuum, among other things.
I’m looking at some pumps and wonder if anyone has personal experience as to how they would fit into the work we’re doing.
I’m currently running a 7 cfm oil rotary vane pump that is getting down to 230 microns (.23 torr or 29.9 inHg) but with some of the larger projects it is inevitable that there are losses in the system that a better pump might help mitigate. When infusing low viscosity epoxy into a 120 sqft layup, the flow curve of my current pump will not saturate the project fast enough, or without loosing all of the debulking.
I’m looking at these pumps:
Welch 1376 Leybold NT10 Leybold D16AC Edwards E2M28
Any information on these or suggestions on other pumps would greatly appreciated.
