awesome little setup. pump is WAY stronger than i expected! i made the mistake of not watching the hose and some of my acetone/poly-acrylic climbed into the pump/oil reservoir while it was running. i didnt know this at the time and i didnt find out until a few days later i went to turn it on and the pump was seized up (due to operator error) because the fiberglass paddles got gunked up and couldn't expand or retract which created the vacuum, because of the junk i let get inside. so i took the pump apart and sanded the paddles down and slapped her back together and she works great! i keep the hose in an "A" shape while I'm running it so pump oil cant get in the chamber and also my epoxy mix doesn't get sucked up inside the pump.. gravity saves the day again.. great little pump.. i was really amazed at the quality of the machining and materials. (I expected much less for what it cost.) if you're looking for a vac chamber...well... this little setup is worth EVERY penny...! just keep the hose high in the center!
