What should I know about buying a used (or new) pump?

Closed system vs. open system pumps

When you are buying a pump, whether it be new or used, it is important to know whether is has an open or a closed system. 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, it’s really hard to say what to do if you find signs of contamination in your pump – the potential for illness is there but we don’t know how likely it is.

CLOSED system pumps include:

  • Ameda: Elite, Platinum, Purely Yours
  • Bailey: Nurture III
  • Freemie: Freedom, Equality
  • Hygeia: EnDeare, EnJoye
  • Lansinoh: Signature Pro, Affinity Pro
  • Lucina: Melodi One
  • Medela: Lactina, Symphony
  • PJ’s: Comfort, Bliss
  • Rumble Tuff: Serene Express Duo
  • Spectra: M1, S1, S2, Dew 350

OPEN system pumps include:

  • All Medela pumps EXCEPT Lactina/Symphony/other older hospital grade pumps.

Contact your pump manufacturer if you are unsure whether your pump is open or closed system.

Keep in mind that there is a difference between a closed system pump and a multiple user pump. Many closed system pumps are not designed to be used by more than one person – in fact, most pumps purchased by mothers are intended to be single-user pumps, and the manufacturer warranties and motor life will reflect that fact.

Motor life

Another issue, particularly important in previously-used pumps, is motor life. Most breastpumps are designed for a year or so of typical use (some have a longer life – check your warranty to get an idea of the expected life of your pump). After that point the motor may not function as well, potentially affecting the pump’s milk output. If you buy a used pump, the motor may already be near the end of its expected lifetime. Many pump rental stations will have a vacuum tester and can test your pump to see if the appropriate vacuum levels are being reached.

FAQs

If you find mold growing in your pump, is it safe to use the milk you have already pumped? Unfortunately, we have no studies on the subject to guide us. It may not be a major issue if you have an older healthy baby, and the pump has only been used by you (the baby’s mother). There would be more concerns about the safety of the milk  if you have a preemie, newborn, or any baby with a compromised immune system. If the pump is an open system pump that has been used by more than one mother, there may be unknown contaminants present,  so it would be difficult to determine the safety of using the milk.

Can I recycle my old pump? Hygeia has a recycling program for their pumps. For other pump brands, call the manufacturer to ask if they have a recycling program in place. In addition, many communities have an electronics recycling service that you can take advantage of.

How can I get help with the expense of a new pump? If  you are in the US, check your insurance coverage! Certain pump rentals, purchases, and lactation counseling are 100% covered by health insurance if your plan year begins 8/1/2012 or later. If not covered by your insurance, breast pumps and supplies that assist lactation are (as of 2/28/11) considered a deductible medical expense. More on legislation here.
