Automatic Feed Pump Control System (AFPCS) Brochure

AFPCS is used in conjunction with air-operated diaphragm (AOD) feed pumps to automatically increase the feed pump pressure during the filtration cycle. High initial feed pump pressures can build a very tightly packed, impermeable layer of solids on the filter cloth, restricting the flow of slurry and ultimately the density of the cake. Reduced initial feed pressure allows a soft layer of slurry particles to be deposited on the filter cloth. This layer becomes the filtering media, enhancing the filterability of the incoming slurry.
