What Is A Chemical Metering Pump?

A chemical metering pump is a type of pump that is created to specifically move chemicals at very accurate flow rates over a particular period.

Some people refer to them as chemical dosing pumps or chemical feed pumps. They are used in a variety of applications and come in different types.

What Factors Should I Consider When Selecting Chemical Metering Pumps?

If you want to select the best chemical metering pump, you should consider a few things.

These include the flow rate, pump accuracy, turndown ratio & control, and construction material. These will help you pick a metering pump that meets your needs and demands.

How Does A Diaphragm Chemical Metering Pump Defer From The Peristaltic Chemical Metering Pump?

The diaphragm metering pump and the peristaltic metering pump are positive displacement pumps. However, they differ as they use different methods to pump the chemical.

The Diaphragm metering pump moves liquids using a reciprocating diaphragm. On the other hand, the Peristaltic metering pump uses rotating rollers to compress a flexible tube to move the liquid in a pressurized flow.

Additionally, peristaltic pumps are easier to use because they don’t feature a lot of parts like diaphragm chemical metering pumps.

Also, diaphragm metering pumps require regular to perform optimally, while peristaltic pumps only need regular changing of the pump tube.

What Are The Benefits Of Metering Pumps?

Metering pumps are very vital and offer a lot of benefits to industries. It doesn’t matter if they are used to dispense accurate chemicals or other fluids. Here are some of their benefits:

  • Moving different types of liquids
  • They can be utilized in different applications such as manufacturing, medicine, processing, agriculture, and much more.
  • They move low amounts of liquids at a very accurate rate
  • They avoid contamination, which is vital when dealing with chemicals

What Determines The Type Of Chemical To Pump?

Not all chemical metering pumps can be utilized to pump any chemical. You need to have the right pump, whether it is sodium bisulfite, sodium hypochlorite, sodium hydroxide, or emulsion polymer.

Always ensure that the pump’s wetted parts are compatible with the pumped chemical. For a diaphragm pump, the components include pump head, diaphragm, injection fitting, valves, and tubing.

And for a peristaltic pump, they include injection fitting, pump tube, and connection tubing.

Bottom Line

With this detailed guide and review, choosing the best chemical metering pump shouldn’t be a problem.

Always take your time and pick the right pump according to your needs and applications. Also, consider the chemicals you’re going to pump and the size of the project.

Note that diaphragm metering pumps are excellent at pumping clean, strong chemicals into high-pressure systems. In contrast, peristaltic metering pumps are fantastic at pumping dirty fluids that have trapped gases or particulate matter into lower pressure systems.

All-in-all, these two chemical metering pumps are reliable in performance and durable. I hope you’ve found a metering pump that will help you achieve your goals!
