The Metering pumps are positive displacement chemical dosing devices that may be adjusted manually or automatically depending on the process conditions. It is capable of pumping a wide range of chemicals, including acids, bases, corrosives, viscous liquids, and slurries, with a high level of repeated precision. A metering pump delivers a precise volumetric flow rate by transporting a certain amount of liquid over a given period of time. The supply of fluids at precise, predictable flow rates is referred to as metering. Despite the fact that a few types of pumps are far more suited than most others, the term “Metering pump” relates to the application or purpose rather than the specific type of pump used.
Chemical Dosing Pumps work by pulling a certain amount of fluid into a chamber and then injecting that volume rate into the dosed container. A Chemical dosing pump is supposed to be dependable as a function, so once correctly set up, it should take care of itself and not require a lot of input. Chemical dosing pumps are used in a variety of industries, including pharmaceutical water treatment facilities, to automate fluid flow. The pump operates in an intermittent mode, creating a magnetic field each time a pulse hits the magnet. The piston is pushed by the magnetic field. The liquid is compressed into the pump head by a diaphragm (Attached to the Piston Head).
While the suction valves close, the liquid escapes via the delivery valves. When the pulse stops, a spring returns the piston and diaphragm to their original positions. While the delivery valve is closed, the vacuum generated by the diaphragm action draws liquid into the pump head from the suction valve. The pump capacity is related to the number of strokes and the internal volume of the pump head (Single Stroke Injection Quantity). Pumping equipment is in high demand in the chemical sector. Any disruption in production or the spilling of fluid may be expensive and dangerous to one’s health and safety.
