Lately we have received many inquiries for pumping thicker products such as glycerine for hand sanitizer production. This will not work well with a standard centrifugal pump as you would use for alcohol, wine or beer as glycerine is too viscous. You will need a positive displacement pump of some design. Luckily there are many different options. Here are three to consider.

If you are pumping in out of barrels then the obvious solution in a progressive cavity gear drive pump like the FLUX F550. These pumps will easily handle this application as the rotor/stator assembly is submersed in the liquid.

If you are pumping larger quantities, or pumping out of something other than a barrel, you might look at a FIP (flexible impeller pump). These pumps have great suction capabilities and handle thick product easily. They come in various sizes and we have them with connections from 1” through 2 ½” and are reversible and variable speed so you can control the flow with just the push of a button.

A third choice would be an AODD (air operated double diaphragm) pump these pumps are fairly inexpensive and portable but they do require quite a lot of compressed air so make sure that you have a good sized air compressor with lots of excess capacity.

I mention glycerine but these pumps would work for many applications, such as aloe Vera gel, shampoo, fruit purees, honey, etc.

I hope this helps, but if you have specific questions please feel free to contact us and we will help you select the correct one for your needs.
