Tender Backflow Protectors for Spectra or Cimilre Breast Pumps (2-Piece Set)

Add to cart

These essential pump parts act as a barrier…

To prevent milk, moisture, and condensation from entering the tubing or motor, supporting both pump performance and milk safety.

Unboxing and first look

Each set includes 2 complete backflow protector units:

  • 2 × Large Caps

  • 2 × Small Caps

  • 2 × Silicone Membranes

Everything you need for a full replacement or spare set.

Backflow protectors are a critical hygiene component of closed-system breast pumps. They:

  • Prevent milk from flowing into pump tubing

  • Reduce the risk of mold and bacterial growth

  • Protect the pump motor from moisture damage

  • Help maintain consistent suction and pump longevity

For pumping mums, this means safer milk, better pump performance, and peace of mind, especially when pumping multiple times a day.

Why Backflow Protectors Matter

Understanding Silicone Membrane Wear & Tear (Important for Pump Performance)

Silicone membranes are the most delicate and hardest-working part of a backflow protector. They play a key role in maintaining suction and creating an effective seal, which is why they are also the component most prone to wear and tear over time.

How long a silicone membrane lasts depends greatly on how it is handled and cared for, rather than just how often it is used.

    • Stretching or pulling forcefully during assembly or removal

    • Using fingernails or sharp edges to pry the membrane out

    • Twisting aggressively when disassembling

    • Washing with very hot water repeatedly

    • Using strong detergents, brushes, or UV sterilisation methods too frequently

    • Not fully air-drying before reassembly, causing the silicone to weaken over time

    Even small micro-tears or loss of elasticity can affect suction without being immediately visible.

    • Noticeable drop in pump suction

    • Milk backing up into the backflow protector

    • Membrane looks stretched, warped, cloudy, or no longer sits flat

    • Pump sounds different during use

    Replacing worn membranes promptly helps protect both your pump motor and milk supply.

    • Remove the membrane gently using the edges, avoid pulling from the centre

    • Wash with mild soap and lukewarm water

    • Avoid excessive rubbing or scrubbing

    • Air-dry fully on a clean towel before reassembling

    • Assemble slowly, ensuring the membrane sits flat without stretching

    Handled with care, silicone membranes can maintain effective suction for longer and reduce the need for frequent replacement.

Complete Your Pumping Setup

Choosing the right flange is important, but pain, low output, nipple trauma, or ongoing pumping struggles often need individualised assessment, not just a product change.

If you’re unsure about your flange size, experiencing discomfort, or want to optimise your pumping routine, professional support from an International Board Certified Lactation Consultant (IBCLC) can make a meaningful difference.

Need Personalised Pumping Support?

1:1 Pumping Consultation (Dedicated & Individualised)

A 1:1 pumping consultation offers dedicated time and personalised assessment, making it the best option if you have specific concerns or ongoing challenges.

This option is recommended if you:

  • Are experiencing persistent pain, nipple trauma, or poor milk drainage

  • Have tried multiple flange sizes without improvement

  • Are exclusively pumping or pumping frequently

  • Want a deep, individualised pumping assessment

  • Are returning to work and need a tailored pumping plan

What makes 1:1 support different:

  • Extended, uninterrupted time focused solely on you

  • Detailed nipple and breast assessment

  • Individualised flange sizing and optimisation

  • Pump settings, rhythm, and suction troubleshooting

  • Personalised recommendations based on your goals, body, and lifestyle

Pumping 101 Workshop (Group-Based & Practical)

The Pumping 101 Workshop is a small group session designed to build strong foundations and confidence, especially for mothers who are new to pumping or preparing ahead.

What you can expect in the workshop:

  • Education on evidence-based flange sizing

  • Guidance on how to measure your nipple diameter correctly

  • Opportunity to try a few flange sizes (depending on the pump you bring)

  • Bring your own pump to check basic fit and comfort

  • Opportunity to try other pump brands, if you wish, during the session

Best suited for mothers who:

  • Want to understand pumping before committing to multiple parts

  • Are preparing to pump at work

  • Prefer learning in a supportive group environment

  • Do not currently have complex pain or pumping issues

Not Sure Which Option to Choose?

  • Choose 1:1 support if you want dedicated time or have ongoing discomfort or complex concerns.

  • Choose the Pumping 101 Workshop if you want education, hands-on learning, and to explore flange options in a group setting.

  • Many mothers start with the Pumping 101 Workshop and later book a 1:1 consultation if deeper support is needed.

  • These backflow protectors are designed and tested for Spectra and Cimilre breast pumps.

    However, from a functional standpoint, a backflow protector can technically work with any breast pump as long as the pump tubing fits securely onto the backflow protector and an airtight seal can be achieved.

    That said, using these parts with pumps outside the listed compatible models would be considered a personal pumping “hack” setup. This means:

    • Fit and suction may vary depending on the pump and tubing used

    • Performance cannot be guaranteed outside recommended models

    • The user assumes responsibility for ensuring proper fit, hygiene, and function

    If you are experimenting with a customised pump setup, ensure there is:

    • No air leakage

    • No milk backflow into the tubing

    • Stable and comfortable suction during pumping

    IBCLC note: If you notice reduced suction, unusual pump sounds, or milk entering the tubing, discontinue use and return to a standard, manufacturer-recommended configuration.

  • Yes. They are designed to fit standard Spectra-style flanges, including Maymom and Tender flanges.

  • Replace if you notice reduced suction, visible wear, or moisture entering the tubing.

    • Exclusive pumpers: 3 months

    • Moderate pumpers: 6 months

    Many mums keep a spare set for convenience.

  • Yes. All components are BPA-free and suitable for use in breast pump systems.

  • Yes.

    Backflow protectors are what make a pump closed-system, they are essential for hygiene and motor protection.
