Is a commerical off the shelf device that creates a vacuum OK, if we power it with a motor supplied in the KOP?

Ken,

I would consider re-wording the question. As it is, I find it confusing.

Do you mean:

a) Can we buy a suction cup and drive it down with a kit motor for the purpose of creating a vacuum (at the suction cup)?

or

b) Can we buy an off-the-shelf impeller and drive it with a kit motor, thereby creating a vacuum pump?

Based on past competitions, the answer you would get would be quite different for these questions. Based on history, they would say 'yes' to question (a), but 'no' to question (b) because of safety.

If I were to read the question as worded, I would think that you meant (b). If you mean (a), I would explicitly state that you mean a suction cup.
