5 Tips While Choosing a Metering Pump

Metering pumps come in handy in helping to transfer a predetermined volume of viscous liquid, such as solvents, bases, acid, wastewater applications, and municipal water in a specific time frame from one place to another. Also, you can alter it to provide different flow rates depending on its uses. Sometimes you may need to purchase a new metering pump or change some of its parts. What are some of the things that you should consider as you choose a metering pump? Below are some of the tips that will help as you select a metering pump.

Thus, share this information with the manufacturer as they know better options and designs. Also, consider all the conditions under which the pump will have to perform to ensure that you do not overlook the application condition. Besides, ensure you point out that the use of the pump will be for a metering job. To get better accuracy, sacrifice the added clearances that are applied to pump parts to make it a high viscosity for a cost of high horsepower requirements. 

2. Compile application data

Ensure that you have the complete and correct application data to ensure that the pump works out correctly, even under minimal maintenance. Therefore, there is information that you can share with your pump manufacturer to get the right pump for the job. This will help them get everything right even though they have to source for other parts online or in the industrial surplus to give you the pump you need. Thus, share the flow rate, viscosity, inlet and discharge pressures, the fluid that will be in use, motor data, whether it is a phase, voltage, or hertz, and whether they will be any solids present.

3. Type of storage 

type of storage

How will you store the pump? Will you have to store it for a long time? For instance, if you have to store the pump between uses or for a long time. You will have to apply a coat of oil to unpainted or machined surfaces and use special materials for storage.
