Matala Hakko Diaphragm Kits bring your Hakko pumps back to full potential, and are simple to install. All you need is a medium Phillips screwdriver, a small Phillips screwdriver and a pair of pliers.

Note: If your diaphragm kits are frequently blowing out, you most likely have excessive back-pressure. Check airline for kinks and check air diffusers for clogging. Ceramic air stones typically need to be cleaned every 3 months. For the best protection against excessive back-pressure, we recommend using a gang valve (see image and link below) and keeping an extra valve open.  During setup, use this extra valve to "bleed off" excess air so that there is not excessive back pressure.  Slowly close the extra valve until the air flow is at its maximum.  Do not continue to close valve beyond maximum airflow, as this excessive back pressure will shorten the life of your air pump diaphragms.

Matala Hakko Magnets move with the diaphragm and holds the diaphragm secure. Using worn diaphragms for extended periods of time will wear down the magnet. If you open the motor for repair and find dust or small metal particles, you may need to replace the magnet. Always inspect the magnet for wear when replacing diaphragms.
