Several types of pumps can be used for metering. This post is going to focus on two different types – peristaltic vs diaphragm pumps. Either pump will provide many years of efficient use, but when you’re deciding which to purchase, it’s useful to know how each works.
Using a diaphragm pump requires you to be knowledgeable about aspects such as pump valves and proper priming, but once you have an understanding of the pump, it should be easy to use. It’s important to note that these types of pumps have a flexible diaphragm that works by vibrating to create suction to move liquid into and out of the pumping chamber. There are many advantages that these types of pumps offer:
Peristaltic pumps are more commonly known as hose pumps. They function by using a roller device that simply moves the liquid through a hose. The fluid that is being moved doesn’t come into contact with the outside environment or the pump at all as it’s contained entirely within the tube or hose.
As you can see above, some needs will be better met with a peristaltic pump vs a diaphragm pump and vice versa. To summarise, diaphragm pumps will work best with cleaner liquids and harsh chemicals in low pressure situations, whereas peristaltic pumps will perform more effectively with thicker fluids in high pressure situations, but they must be more closely monitored to prevent leaks.
Using a combination of your own research and the information above, you will now have a wealth of information to help you decide which pump is best for you. At Pumpworks we understand pumps and the need to choose right, so get in touch today and let us do what we do best – help you.
