Diaphragm pumps make it possible to displace a large volume of fluids or materials in an efficient way. While most applications involve standard-sized pumps, some do require a mini diaphragm pump. These mini versions still provide excelled displacement potential but are designed for use in smaller-scale operations. If you need to invest in a miniature diaphragm pump, it is helpful if you have some initial guidance to help you along. Here is a look at some of the general questions you may have about miniature diaphragm pumps

How do you select the best mini diaphragm pump for you?

You have three main factors to look at when you are investing in a mini diaphragm pump, including: 

  • The volume of the pump 
  • The diaphragm drive type 
  • The material the pump is created out of 

Therefore, essentially you need to know how much material you expect the pump to handle, which drive type will serve your intended purpose the best, and what materials will stand up in the setting. For example, if you know you need a high volume of material pumped, you would opt for a miniature pump with a higher-volume displacement capacity. Likewise, if you will be installing the pump in an outdoor setting, you may want to look for a pump with a corrosion-resistant exterior shell. 

Do miniature diaphragm pumps require as much air pressure as standard pumps?

The interior chamber of the mini pump can only house so much air, depending on the size of the chamber. With that being said, the pump will not require as much air pressure as a standard-size pump simply because there is not enough space for extensive amounts of air within the chamber. Check with the manufacturer's guidelines to determine how much air pressure should be used. Keep in mind that most diaphragm pumps are capable of handling a predetermined range of air pressure. 

Are miniature diaphragm pumps still capable of self-priming?

One of the many features that users enjoy about standard diaphragm pumps is the fact that most pumps are self-priming. Mini diaphragm pumps tend to offer the same convenience, but it can also depend on what pump you are using and what the pump is being used to move. If you are using the pump to displace a heavier fluid, it may be harder for the pump to draw in enough air and fluid to get the pump properly primed.
