How i can empty a cartridge with an electric pump?

Hello, what kind of electric pump should i use to make an automatic emptyning system?
Until now i was using a Syringe and a clip to empty the cartringe but i need something faster and more automated!
Thank you.

I did this for a bunch of HP10/11 and 88 cartridges... consisted of a pump with a tube that went to a rigid container lid, then another tube that was connected separately to the rigid container and on to the cartridge connector.

The rigid container in the middle collects any liquid and stops ink getting to the pump and fouling it.
