Would A Peristaltic Pump Or A Diaphragm Pump Be The Best Option For My Needs?

Husky 2200 Pump

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.

Diaphragm Pumps

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:

  1. They are less expensive in the long term, as long as they are maintained well, and they are more energy efficient because they are designed to use more force on the forward stroke than the back. 
  2. They are perfect for pumping harsh chemicals as they rarely leak or cause any damage to surrounding areas. 
  3. They are known to be correctly sized better than other options because they can overcome standing pressure.

Peristaltic Pumps

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.

  1. Using a peristaltic pump is easy and convenient as it has no valve checks that can become clogged and so can operate even with dirty liquids. 
  2. Manufacturers rate hoses for a certain number of usage hours to prevent leaking or rupturing, so the lifespan needs to be closely adhered to. 
  3. They can handle higher back pressures, are easier to prime, and maintain good suction for the majority of fluids.

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.
