If you have a perfect vacuum there should be no need to lkeep it running Matthieu Libeert Founder MAT2 Composites X Sports website: www.mat2composites.com

It has a return valve to prevent the oil being sucked back out of the pump. (Seems a simple precaution, but not standard on the EC pump??) "Sapere Aude"... Dare to KNOW! The written word is the only truly efficient vehicle for transmitting a complex concept from mind to mind... 103% of all people do not understand statistics... Do not adjust our mind, theres a fault in reality :-)

If you turn the pump off without turning off a valve you will find your Pump oil gets sucked out, so I don't think you want what you are asking for. Brian. As we are new to the composites industry, we made the mistake of leaving the valve opened for a short period whilst the vacuum pump was off after resin infusion which saw the pump oil being sucked out. We closed off the valve as soon as we saw this happening.. Just wondering if this would have done any damage to the pump? (it is brand new) And if its just a matter of topping it up with fresh oil? Regards, JD

I feel that running a pump continuously is costing me too much in power use when if set up with a tank it may only run for some minutes each hour? It would also be much quieter and save wear on the pump? Fastacraft Facebook page

What you're asking can be done much simpler, just use one of these: There's no harm in running your pump under very little load for hours at a time. What Brian says is true though, it will suck the oil out of your pump if the valve is left open. So long as you have a catch can with nothing between it and the pump (like a leak indicator) then it's totally fine, you won't damage your pump or do anything any harm, provided you refill the pump with oil (not the stuff that came out of it) before you use it again.
