Two pumps together.

[FragIt Dan]

I would not assume so, but maybe. Magnetic fields decay with distance exponentially, so putting them directly beside each other (touching) might cause influence on each other. This could theoretically pull one of the motors or impellers aside causing premature wear. IF this happens, it is hard to say how much additional wear this might cause. You could perhaps start the one pump up while holding the other and see if there is any jarring in the pump you're holding. I would think any influence would cause a pull on the other pumps components that would wear them out too quickly, but that is really just a guess.
