![]() ![]() ![]() Because the pumps can operate at varying speeds, they are ideal for the transfer of abrasive pigments and highly viscous paste through the paint processing stages of grinding, thinning, straining and packaging. They can handle a range of viscosities - from water to 90 percent solids - which is perfect for accommodating the varying quality of resins and paint slurry. These AODD pumps are designed to meet the specific needs of latex pumping facilities. The initial chemical additives are mixed using these pumps.Ī pump and filter unit used for pumping latex base. Repeat attempts often wasted valuable work time. Workers also could not determine if the O-rings had been positioned properly until the whole pump was reassembled. In addition, whenever a diaphragm would rupture, cleaning and replacing up to seven O-rings with an O-ring pick was difficult because the center block bushing was so small and complex. Workers kept hammers close by at all times. Throughout the facility, processors had to run a constant, costly, and messy stream of water across the old pumps to try to prevent freezing and stalling, but the pumps often failed anyway. The time savings substantially improved efficiency, and still continues to lower the total cost of ownership today.Ī cutaway image of the inside of the pump that eventually replaced all of the AODD models used in this latex paint manufacturing operation.īefore this base latex manufacturer implemented the air valve system, maintenance was a key pain point. This resulted in a significant increase in productivity and a solid return on the investment. Eventually, the company replaced all 150 of its AODD pumps with models using this patented air distribution system. The valve proved so reliable that the manufacturer installed more – on 70 percent of its pumps. Searching for solution to these problems, the manufacturer agreed to install an Elima-Matic® air valve on a trial basis. ![]()
