I like to know which pump is really suitable for a Vaccum Infusion Process for a 32 ft hull of around 75 sqm surface. We have a reconditioned Edwards ED200 High Vacuum Pressure Spideevac capable of 29,9 Hg but we don’t know (and cannot find) the speed specs (How many CFM or M3/hr). Somebody said that this pump is really obsolete. We had tried this pump for a small hull infusion and worked well but we are afraid that it couldn’t be sufficient for a 32 ft hull. Anyone know the specs for a pump suitable for this application? How many CFM?
any answer welcome.
Try using a 15600 model Robinair Oil Rotary Vane Vacuum Pump. CFM of the pump doesn’t matter. But just get one with 6 cfm. They’re about $250 on ebay. For a 32 ft hull. Try using several pumps at the same time.
How we can put different pumps with different CFM and ultimate pressure? Do You have any idea or sheme? We have three different pump, each one as different CFM speed and different ultimate pressure, all can work continuously.
My suggestion would be to use all robinair vacuum pumps because they are proven to work for the process. Im not sure what the effect would be if you used 1 robinair pump and another different pump. If you have your vacuum line going to both pumps and you can pull full vacuum pressure…you should be good to go. Use a T-barb fitting to split your vacuum line into to lines with each on going to a pump.
