I'm not only a newbie, but not even a model maker, so please forgive the odd questions.
For some biomedical research I need to produce positive and negative pressures in a small air cavity. I came across the GSV2512N12V 'Air Pump For Subs' and wonder if it might work for me. One question is whether by any chance it can be run backwards by reversing the voltage, to produce either positive or negative pressures in a cavity. If not, perhaps I could hook up two of them, one to push air into the cavity and one to pull it back out? When the pumps are stopped, are they air-tight?
(The cavity volume would be on the order of 1 mL, but a larger buffer volume can be used. The pressures would be something like +/- 5 kPa. We'd be using a pressure sensor to measure the actual pressure.)
I also noticed the 400P Gear Pump. It is reversible but it's intended for water, and I haven't found any specs or price for it.
Thanks for any advice you can give.
