Diaphragm Pumps versus Peristaltic: Which One Do I Choose?

When choosing a pump, consider your own needs. Both styles of pumps have advantages and disadvantages associated with their use. Peristaltic pumps are easier and simpler to use, at least for the novice, requiring much less experience before using. They can also be operated under conditions less than ideal. This is why many people choose this pump style over a diaphragm pump. Over the years, diaphragm pumps have gotten much easier to use. If you are an expert, you probably want to stay the course with the pump style because the cost to operate over time is less than the alternative.

Diaphragm pumps are more energy efficient, overcoming issues of line pressure is also easier than with the peristaltic, and there is far less danger of leakage. Although they require more experience to maintain than their competition, they are a better deal for most as they are a far more cost effective solution. Diaphragm metering pumps are good at pumping clean chemicals into high pressure system, while peristaltic take dirty fluids and pump them into low pressure systems. While diaphragm pumps are less than ideal when dealing with dirty fluids or trapped gasses, with a knowledgeable team they will still fulfill their role nicely and save you money. All new pumps will require you to spend more in maintenance than the cost of the pump over time, so when choosing which style of pump it is wise to consider the long-term. When you're looking at a range of $3,000 to $12,000 a year in operating costs, most people will want to lean towards the pump that is closer to $3,000.

Choosing between the two usually is a matter of cost, capability and the current breakdown of the system you are trying to maintain and use. Researching the two products and their manufacturer will enable you to have a good base of understanding when it comes to the installation and maintenance of these systems. Who will be maintaining it? What is your budget for the next five years? Be sure that you have a full understanding before investing money in a pump for your application.
