The 9 Best Peristaltic Pumps
This wiki has been updated 11 times since it was first published in August of 2019. A peristaltic pump utilizes the action of rollers to push fluids through a tube -- a mechanism that makes them ideally suited to handling fluids containing trapped gases or particulate matter. They are ideal for a variety of uses, including sterile applications, filling containers with consumables, and in agriculture.

A peristaltic pump operates on a system of internal rollers that ‘push’ liquid entering through a tube from one end out to the other end.
When shopping for a model, you’ve got to be careful not to mistake diaphragm for peristaltic. Both are positive displacement pumps (the other primary type being centrifugal pumps) that are advertised for similar applications; a good rule of thumb is that unless the manufacturer/seller explicitly mentions the word ‘peristaltic’, there's no guarantee that it's not another type of pump.
Compared to diaphragm pumps, peristaltic pumps are generally better at self-priming, less susceptible to flow rate changes due to pressure and better at handling ‘dirty’ fluids or liquids with lots of particles, among other benefits.
While nearly all peristaltic pumps run on a DC motor, most cheaper options come without a transformer/DC power source, and thus an external DC power source or transformer needs to be made available from the consumers end.
You can connect a variable DC source to the motor cables, which can be used to lower the voltage and in turn control the RPM (Rotations Per Minute) of the internal rollers, and therefore the flow rate. Models like the Stenner 85MFH2A1S and Anyilon SDK-101 come with an internal AC transformer and adapter that can be plugged into the mains.
The Anyilon has the built-in advantage of a voltage controller on the dashboard, while the Stenner does not; in that sense, its a great model that combines ease of use with variable rotational speed and a durable, long-lasting build.
The Gikfun AE1207 on the other hand is the best value for money for an end user who's looking for a no-frills model. Other models at a similar price point tend to suffer from overheating and other problems that the AE1207 avoids for the most part.
