A filter’s diaphragm is responsible for moving water in slurry through the filter media by either compressed air or pressurized water.

The diaphragm is essential in transferring the pressure to the slurry for effective dewatering, where most water not adsorbed on the solid particle surface is drained from the plate chamber.

Diaphragms are made from polymers that operate under continuous strain and stress due to the stretching and contraction after every filtration cycle. Diaphragms, therefore, are consumable parts that require frequent replacement.

The replacement frequency depends on process-specific conditions and will vary between different customer applications.

Diaphragms need to follow strict quality controls in both dimensions and materials of construction, to ensure reliable and optimal lifetime that minimize unexpected diaphragm failures (such as leaks affecting cake moisture quality) and costly unplanned shutdowns for diaphragm replacements that impact production.
