Metering pumps are designed to move a controlled volume of fluid within a specified period. This process is known as metering or dosing, hence the name metering or dosing pump. These pumps are used to distribute liquids, such as chemicals and solutions. Some common industrial uses for these are water treatment plants, chemical processing plants, and many different agricultural applications. The selection of the right dosing pump for the proper application is of paramount importance in every industry. Due to variations and various chemical pumps available, selecting the correct chemical metering pump can be tedious.

Below are 6 factors to consider when selecting the right pump for the best application:


Flow Rate

Knowing your expected or desired flow rate is crucial in choosing the proper dosing pump for your application. The desired flow rate is measured in gallons per minute (GPM) or liter per hour (LPH). A good rule of thumb is to ensure that your maximum expected flow rate is equal to 90% of the pump’s capacity. This way, you will give room for a small increase in the flow rate if needed.



Another factor you should consider when selecting your pump is the pressure conditions on your pump’s inlet and outlet. This information will help you to choose the right dosing pump.



How hot will the fluid you are pumping be? The answer to this question will affect which pump materials are best suited for your application.



To select the right pump, you need to know the viscosity of the fluid to be pumped. High viscosity fluids require more robust pumping equipment.


Liquid end material:  A key factor to consider when choosing a metering pump for an application is the nature of the chemical to be dosed. This will dictate the suitable liquid end material for the metering pump.

Operating Environment

Another essential factor you need to keep in mind is the operating environment, which is usually overlooked, but it has a significant impact on the pump’s performance. If the pump is operating in a cold temperature environment, you must make sure that the fluid that is being pumped will not freeze at that specific temperature.
