An Overview of Chemical Dosing Pumps
A dosing pump, which is a positive displacement pump, is a critical component in industries that deal with waste water. Used in conjunction with other equipment, these small pumps are used extensively for controlled chemical addition to a process. The accurate and precise dosing of chemicals at a controlled and consistent rate are beneficial for disinfection, flocculation and coagulation, nutrient removal, sludge conditioning, and alkalinity supplementation, among others.
With increased operational safety, high feed pressures, leakage-free functioning, and highest dosing accuracy, our range of chemical dosing pumps adeptly meet the requirements of the most industrial and commercial applications.
Working Principle of Chemical Dosing Pumps
Chemical feed pumps work with a simple mechanism. The dosing pumps motor drives a piston, which creates a vacuum. The generated vacuum draws chemicals to be dosed from the pump’s external tanks into the liquid end of the pump. The pressure created by alternating piston strokes closes the inlet valve, opens the outlet valve, and drives the chemical out of the pump. A diaphragm within the liquid end functions as a barrier between the piston and the process fluid. As the piston reciprocates, the resulting motion causes the diaphragm to flex back and forth. The diaphragm flexes as the piston moves; the more the diaphragm flexes, the higher the pump's flow rate. The rate of flow can be well managed as per the dosing requirements using air actuator or electric motor attached to the controller of the pump.
Key Considerations When Choosing Chemical Feed Pumps
To get the maximum out of dosing pumps in terms of efficiency, system safety and minimum downtime, it is critical to select them wisely considering several factors. A few of the critical elements to consider when choosing a chemical dosing pump are as follow:
- Rate of the Flow: Make a selection after analyzing the expected or desired flow rate. The pumps should never be under or oversized as the incorrect sizing affects the precision flow requirements. Ensure to choose a large sized chemical feeding pumps for applications involving a higher flow rate.
- Operational Environments: Consider the environmental elements which they may be exposed to during their operation. This is important because, there are feed pumps available to withstand the harshest environments, incorporating features like totally enclosed, chemically resistant housing, encapsulated electronics and stroke bracket, among others.
- Materials of Construction: Chemical dosing pumps are manufactured utilizing a wide range of materials. In case your pumps are meant to deal with highly corrosive chemicals in their day-to-day applications, it is critical to use heavy duty pumps made of materials that can stand the test of the time.
- Type of Pumping Fluids: Considering the type of fluids to be pumped is a critical element to avoid corrosion, wear, and tear. If your requirement demands pumping a slurry (thick suspension of solids in liquids), then it is recommended to invest on pumps with special diaphragms, injectors and other components.
Additionally, checking the desired capacity, leak protection mechanisms, temperature and pressure ranges, life expectancy, and method of control must be carefully evaluated before sourcing the item. At Cannon Water Technologies, we provide expert advice that leads you towards a wise pump selection.
