Re: pic: Meet Oscar...(1108)

when you shut off the impeller does the ball release right away?

we are using a commerical piston vaccum pump with commercial suction cups - we get about 25 inches of vacuum, but one thing we have to work out it that when we stop the pump, it takes about 6 to 8 seconds for the ball to release.

we are thinking of either inducing some leakage, or adding a solonoide valve to release the ball.
