Installation Direction Of Diaphragm Pump Diaphragm

Jun 28, 2024

There is indeed a distinction between positive and negative installation of the diaphragm inside the diaphragm pump. This can be seen from the appearance of the membrane, which has different designs on both sides, so it is necessary to pay attention to the front and back steps during installation.

When installing the diaphragm, the side with the lettering should be placed inward, which is the position of the inner pressure plate. When installing the diaphragm, the curved side should be placed facing the diaphragm, while the flat side should be facing the partition. If installed upside down, it may cause rapid corrosion or wear of the diaphragm.

In addition, when installing the diaphragm, it is also important to note that after locking the screw connection between the central shaft and the pressure plate, push in the intermediate body and ensure that the arrow is facing upwards during installation, aligning with the side of the air valve cover.

These steps and precautions ensure the correct installation of the diaphragm, avoiding equipment damage or performance degradation caused by improper installation.
