Diaphragm & Valve for Wearable Breast Pump

Restore Optimal Suction—Essential Replacement Parts for Wearable Pumps

The Problem: Your wearable breast pump's suction is getting weaker. Pumping takes longer, you're getting less milk, and the motor sounds like it's struggling. The diaphragm and valve have worn out from regular use, but you're not sure where to find affordable replacement parts.

The Solution: Tiny Bloom Diaphragm & Valve replacement pack includes the two most critical parts for maintaining optimal suction. These small but essential components create the vacuum that expresses milk—replace them every 4-8 weeks to keep your pump working efficiently and protect the motor from strain.

Why These Parts Are Essential

• Create & Maintain Suction: The diaphragm and valve work together to create the vacuum that expresses milk. Without them, your pump won't work at all.
• Wear Out Quickly with Regular Use: These parts do a lot of work and weaken over time from pumping, washing, and sterilizing.
• Replace Every 4-8 Weeks: Depending on how often and how long you pump, these parts should be replaced every 4-8 weeks to maintain optimal suction.
• Weak Parts Strain the Motor: Worn diaphragm and valve force the motor to work harder, potentially damaging it and shortening pump lifespan.
• Affordable Essential Maintenance: At just $12.99, regular replacement is an affordable way to protect your pump investment and maintain milk output.
• Easy to Replace: Simple to swap out—no tools or complicated setup required.
• Compatible with Wearable Pumps: Fits Tiny Bloom wearable breast pumps and other compatible brands.
• Wash Gently: These delicate parts should be washed gently with fingers (not brushes) to prevent tearing.

Signs You Need to Replace These Parts

• Suction feels weaker than usual
• Pumping takes longer to express same amount of milk
• Milk output has decreased
• Diaphragm looks stretched, cracked, or torn
• Valve looks damaged or deformed
• Parts have been in use for 4-8 weeks or longer
• Pump motor sounds louder or works harder
• Parts feel less elastic or flexible

Why Regular Replacement Matters

The diaphragm and valve are the heart of your pump's suction system. As these parts wear out from regular use, washing, and sterilizing, they lose elasticity and effectiveness. This forces your pump motor to work harder to achieve the same suction, which can:

• Reduce milk output by 30-50%
• Double the time needed to pump
• Strain and potentially damage the pump motor
• Shorten overall pump lifespan
• Make pumping frustrating and inefficient

Regular replacement every 4-8 weeks ensures optimal performance, protects your pump investment, and maintains consistent milk output.
