The Best of Both Worlds: Air-Powered Electric Chemical Feed Pumps
Small electric air pumps do more than just cycle air through a container. The simplest forms of small air pumps include pumps used to fill containers, such as inflatable objects, or pumps used to control pneumatic machines and tools. In addition to these simple uses, air pumps combined with fluid pumps, such as the useful diaphragm pump, are able to use air to facilitate the movement of fluid through the pump for higher accuracy and smoother performance.
Diaphragm pumps work by filling a chamber with fluid during the compression phase of the air pump. The diaphragm separates the two chambers to keep the air and fluid separate. The pressure from the air moves the fluid into discharge piping and a small amount of fluid causes the air to compress inside the dampener. This causes the pump to go into suction phase, which causes the discharge piping pressure to fall and forces the fluid out of the dampener. The process then repeats as long as the pump is on. This process helps the flow to continue during the suction phase of the pump, which helps create a smoother fluid flow.
Chemical feed pumps are the ideal use for the mash up between small electric air pumps and fluid pumps. These pumps work smoothly to pump precise chemical mixtures into a fluid for a high level of accuracy and performance. These chemical pumps are often used in waste water treatment plants, process plants, pulp and paper processing, and the textile industry for cleaning and forming fabrics. Without the high level of accuracy that the combination of air and fluid bring to the process, the accurate dosing of the chemical would be impossible, and it would be much harder to regulate the flow of chemical treatment into the liquid.
