What is the difference between metering pump and dosing pump?
A dosing pump is used to deliver or control the amount of fluid passing through the system. Dosing involves dispensing a predetermined volume of fluid on an intermittent basis. Along with dosing pumps, metering pumps deliver a predetermined and controlled volume of fluid too.
What is flow metering pump?
The metering pump is a positive displacement chemical dosing device with the ability to vary capacity manually or automatically as process conditions require.
Where is metering pump used?
A metering pump is used to add small but accurate volumes of a liquid to other fluid streams or vessels. Metering pumps are also called dosing pumps and proportioning pumps. A metering pump must be able to deliver liquid with an accuracy of greater than 3% across a wide range of discharge pressures.
What is a metering pump used for?
Metering pumps are used to pump chemicals, solutions, etc… There are a range of different metering pump technologies, and generally the application drives the pump selection. Critical application criteria include the viscosity, temperature, discharge pressure, required flow rate, and compatible wetted path materials.
How much water does a metering pump hold?
By the numbers, metering pumps have flow rate ranges between.001 gallons per hour (gph) and 20 gallons per minute (gpm), or.038 – 76 liters per minute. The total head pressure of metering pumps ranges between 10 and 30,000 psi (.7 – 2,068 bar), and horsepower can be as low as 0.125 or as high as 5. Pro’s and Con’s of Metering Pumps
What should I look for when choosing a metering pump?
Another major consideration is the accuracy of a metering pump. Depending on the cost of the medium being pumped, the accuracy of the metering pump technology used can have significant cost impacts. For instance if the metering pump selected has poor accuracy then you may be wasting material or not delivering enough.
