Selection of a chemical metering pump that is best suited for your needs can be hard considering the huge number of different types that are currently in the market. Moreover, lack of sufficient experience in the same may also serve to make it hard.
Below are four important factors that one should be aware of before purchasing a suitable chemical metering pump.
Capacity required
When getting a chemical metering pump, be sure to consider the discharge pressure as well as the flow rate that you need in your project and or application. It is also important to note that over-sizing the pump will result in a lot of energy consumption when in operation.
As such, it is best to select a chemical metering pump that can deliver the needed flow rate or discharge pressure at approximately 85% of its capacity. This is to ensure that the pump retains a certain percentage in capacity for instances when requirements exceed the normal requirements of your application.

This is also the case the other way round; the pump should be able to deliver the minimum performance required at about 10-15% of its capacity. This guarantees that the pump will accurately measure the small volumes of chemicals needed.
Compatibility with pump drivers
It is advisable to select a chemical metering pump whose operating system is compatible with the energy available the site of operation.
Material components
Different chemical metering pumps are fitted with different kinds of materials that suit particular applications. As such, it is best to keep in mind the chemicals that the pump will be exposed to. This will help with the knowledge of the type of pump material which will be able to withstand that particular kind of exposure.
Leakage Protection
The ideal chemical metering pump should have a system that will alert you in the event of a leak. This serves to help avoid the accidental discharge of excess amounts of chemicals during the operation of the pump. Failure to attention during a leakage could very well affect the operations.
