A metering pump / Dosing Pump is a pump used to pump liquids at adjustable flow rates which are precise when averaged over time. Delivery of fluids in precise adjustable flow rates is sometimes called metering. The term “metering pump” is based on the application or use rather than the exact kind of pump used, although a couple types of pumps are far more suitable than most other types of pumps.
Although metering pumps / Dosing Pump can pump water, they are often used to pump chemicals, solutions, or other liquids. Many metering pumps / / Dosing Pump are rated to be able to pump into a high discharge pressure. They are typically made to meter at flow rates which are practically constant (when averaged over time) within a wide range of discharge (outlet) pressure. Manufacturers provide each of their models of metering pumps with a maximum discharge pressure rating against which each model is guaranteed to be able to pum against. An engineer, designer, or user should ensure that the pressure and temperature ratings and wetted pump materials are compatible for the application and the type of liquid being pumped.
Most metering pumps/ Dosing Pump have a pump head and a motor. The liquid being pumped goes through the pump head, entering through an inlet line and leaving through an outlet line. The motor is commonly an electric motor which drives the pump head.
In order to avoid leakage at the packing or seal particularly when a liquid is dangerous, toxic, or noxious, diaphragm Dosing pumps are used for metering. Diaphragm pumps have a diaphragm through which repeated compression/decompression motion is transmitted. The liquid does not penetrate through the diaphragm, so the liquid inside the pump is sealed off from the outside. Such motion changes the volume of a chamber in the pump head so that liquid enters through an inlet check valve during decompression and exits through an outlet check valve during compression, in a manner similar to piston pumps. Diaphragm pumps can also be made which discharge at fairly high pressure. Diaphragm metering pumps are commonly hydraulically driven.
Advantages of Using dosing Pump :
- Precise dosage of Chemicals solution
- No leakages or spillage
- Electrically operated and hence can be automised
- Occupies very less space.
Limitations of Dosing Pumps
1 – Required Electricity
- Paper & Pulp Fertilizers
- Oil & gas
- Steel Plants
- Water and Waste Water Treatment Plants
- Sewage Treatment Plants
