A closed system pump has a barrier between the milk collection kit and the pump mechanism to prevent contamination by bacteria/mold/viruses/etc. An open system pump has no such barrier. Note that it is NOT possible to completely sterilize the inside of an open system pump - you would have to dismantle the pump to get to all the parts that could be affected, plus some of these parts are impossible to completely sanitize. Buying new tubing, new parts, and cleaning every cleanable part does NOT sanitize the motor of the pump, which (in an open system pump) is, by definition, open to the new milk you are pumping. So far there have been no documented instances of a baby becoming ill due to contamination from a breastpump, but no one has studied the issue. Without any studies, its really hard to say what to do if you find signs of contamination in your pump - the potential for illness is there but we dont know how likely it is.

Most breastpumps are designed for a year or so of typical use, and after that point the motor may not function as well, potentially affecting the pumps milk output.
