Backflow protection of electric breastfeeding pump


Backflow protection is a crucial element that should be considered when breastfeeding with an electric breast pump. Backflow, also known as “reverse flow”, occurs when milk or other liquids are pushed back up from the collection container and into the tubing that connects it to the breast pump. This can lead to contamination of the entire system, posing potential health risks for both mother and baby.

Mechanisms for protection against backflow

To protect against backflow, electric breast pumps typically come equipped with either a diaphragm valve or an anti-backflow nipple shield. Both mechanisms are designed to stop the flow of liquid from coming up through the tubing and into the pump itself, while still allowing milk to flow down from the nipple into the collection container below. 

The diaphragm valve 

The diaphragm valve is most commonly used in electric pumps, and is a simple device that houses a flexible silicone membrane. When the pump is turned on, this membrane expands to create an airtight seal between the container and the tubing, preventing any liquid from passing through. 

The anti-backflow nipple shield 

The anti-backflow nipple shield works similarly to the diaphragm valve, except that it fits directly to the breast flange. This shield creates an airtight seal between the nipple and collection container, while still allowing milk to flow through a small opening in the middle of the shield.

In addition to these mechanical safeguards, some electric pumps also feature built-in software algorithms designed to detect backflow and shut down the machine if necessary. While these are helpful features to have, it is important to note that they may not be entirely reliable and should always be used in combination with the mechanical backflow protection measures mentioned above.

Tips for Keeping Your Backflow System in Top Shape

Keeping a backflow protection system running smoothly is essential for keeping your electric breastfeeding pump safe and secure. Here are some tips to help you get the most out of your system:

Check It Regularly 

Make sure to routinely inspect your backflow prevention system for any signs of wear or damage. This way, you can catch any problems before they become serious and repair them quickly.

Clean It Often 

Backflow systems need to be kept clean and free of debris, dirt, or other obstructions that could block water flow or cause the system to malfunction. Regularly cleaning your backflow prevention system can help avoid any problems in the future.

Use Quality Parts 

To ensure your backflow protection system is always working at its best, be sure to use quality parts and replacements when necessary. Low-quality parts can lead to malfunctions or other issues that could put your electric breastfeeding pump at risk of harm.

Avoid Overloading 

Overloading your backflow prevention system with too much pressure can cause it to malfunction or become damaged over time. Make sure you are not putting too much strain on your system by only using it within the recommended operating pressure range.

Repair Promptly 

If you notice any issues with your backflow prevention system, be sure to repair it promptly. Don’t wait until the problem gets worse or results in more extensive damage before getting it fixed. 

Benefits of Using Backflow Protection for Electric Breastfeeding Pumps 

Cost savings 

Using backflow protection for electric breastfeeding pumps will help you save money in the long run. Since this technology helps keep your pump clean, it reduces the need for frequent repairs and replacements that come with using a pump without this type of protection. This means you won’t have to spend as much money on maintenance and repairs, which can add up quickly.


Backflow protection helps keep your electric breastfeeding pump free from any bacteria or other contaminants that might be present in the milk. With backflow protection in place, you can rest assured that any milk your baby drinks is safe and free of any harmful substances.

Protection from power surges 

Another benefit of using backflow protection for electric breastfeeding pumps is that it can help protect the pump from power surges. Most pumps are designed to run at a certain voltage, so if there’s an unexpected surge in energy or voltage, it could damage the parts of the pump. With backflow protection in place, these surges are diverted away from the pump so it remains safe and sound.

Improved performance 

Using backflow protection for electric breastfeeding pumps can also help improve its overall performance. This technology helps ensure that all of the parts in your pump are running smoothly, which means it won’t have to work as hard and will be able to provide the best possible performance. This means that your baby will get more milk with less effort from you, making your breastfeeding experience much easier and stress-free.

Tips for choosing backflow protection 

When looking for backflow protection for electric pumps, it’s important to consider a few different factors before making a purchase. 

  • First, you should make sure that the product is designed specifically for your particular pump. This will ensure that it will fit properly and provide the best protection possible.
  • Additionally, you should look for a product with a certification from an independent testing body. This will ensure that the product meets all safety standards and provides the highest level of protection. 
  • Finally, be sure to read customer reviews before making a final purchase. This will help you get an idea of how well the product works and whether or not it’s worth the money.

By taking these steps, you can make sure that your electric breastfeeding pump is protected from any contaminants and possible power surges.
