The replacement diaphragm for the Momini SingleHarm and TwinHarm breast pumps is a small but crucial replacement part that contributes to the effectiveness and hygiene of your pumping. Without it, your breast pump won't function as efficiently as it should.

This small silicone element performs a key function: it separates the milk section from the pump mechanism, protecting the motor from moisture and dirt. A functioning membrane ensures effective and hygienic milk expression.

What is the purpose of the diaphragm in a breast pump?

• Creates a tight barrier between the milk and the breast pump motor.
• Maintains a stable vacuum necessary for effective suction.
• It prevents milk from flowing back , protecting the device mechanism from damage.
• It affects the comfort, safety and hygiene of the entire expression process.

Ensure the reliable operation of your breast pump – choose the original Momini SingleHarm and TwinHarm membrane and enjoy effective, hygienic milk expression every day.
