M.W. Watermark - Model AFPCS -Automatic Feed Pump Control System
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.
The AFPCS automatically increases the feed pressure in four stages throughout the fill cycle. These stages and pressures are fully adjustable to suit the type of slurry and the solids concentration. Cycle corrpletion is determined by rranitoring the feed pump flow sensor, located at the feed pump, during the final pressure stage. The AFPCS also incorporates a low hydraulic pressure safety shut down device. If insufficient hydraulic clamping pressure is present, the system completely shuts down, eliminating any possible leaking from between the filter plates. The control panel features a power ON switch, START cycle and STOP cycle push buttons. The start button illuminates during the feed cycle. The stop button illuminates to indicate the cycle is complete. Automatic Feed-Pump Controls allowyour filter press to run at its optimum efficiency creating dryer filter cakes, reducing disposal costs, reducing operator time, and increasing the life of your filter cloths and feed pumps. Typical payback is less than one year.
