Penguin Chillers offers a line of submersible pumps for use with our glycol chillers.

Standard practice is to use one pump per fermenter or vessel that you wish to cool. In this setup each pump is plugged into its own glycol pump controller. Each controller independently monitors each fermenter or vessels temperature and turns the pump on/off accordingly to regulate the temperature. The controller on the glycol chilling unit itself will regulate the temperature in the glycol reservoir ensuring that there is always cold glycol on hand to be sent out as needed in order to cool the fermenters.

Our pumps work great for brewers that cycle their pumps on & off or choose to run them longer during a cold crash.  We do not recommend them for any application that requires the pump to regularly run for extended periods of time without cycling. This includes draft systems, or brewing setups wanting to use a header line and solenoid valves.  The occasional 8 straight hours of run time shouldn’t be an issue. However, running the pump in 8 hour blocks 7 days a week is going to significantly shorten the life span of the pump.

Pump Size Options:

Glycol Pump – 12v DC  /  19 watts  /  3.5 GPM max  /  16′ Head height max /  3/8″ barb fitting – overall dimensions 3.1″ long, 1.65″ wide, 2.5″ tall

XL Glycol Pump – 24v DC  /  60 watts  /  6.3 GPM max  /  32′ Head height max /  3/8″ and 1/2″ barb adapters included – overall dimensions 3.65″ long, 2.35″ wide, 4.30″ tall

Pump Comparison:

When testing our XL pump under what we consider to be a “normal” setup, we found that the XL pump provided roughly 2 times the flow rate when using 3/8″ inch tubing and 4 times the flow rate when using the 1/2″ inch tubing.


Up to 2 BBL – Standard pump

Up to 4 BBL – XL Pump used with 3/8″ tubing

Up to 10 BBL – XL Pump used with 1/2″ tubing

*Please note that the length of tubing used, any vertical height changes, and the number of fittings used will all reduce the flow of your pump. Our sizing recommendations are just suggestions. In the end your pumps functionality will be determined by your set up and load that the pump is running under.

    I own a small startup brewery in the mountains of Colorado. I called to ask Penguin Chillers if they thought their glycol pump would work to pump glycol through a long-draw draft beer tap system to keep the beer lines cool. I mentioned there is a max height increase of 6′ and is overall a 50′ loop. They said “probably not” so I started my search for a pump that would work. I purchased a $100 pump from Amazon rated for sub-freezing temperatures and designed to power garden fountains and waterfalls and is about 3x bigger than Penguin Chillers’ pumps. That big pump did absolutely nothing and was unable to pump the glycol through even half the system. I decided to test a Penguin Chillers pump since I use them to chill my fermenters and lo and behold it pumped the glycol through like it was nothing. The pumps are not only powerful, but tiny.

    You do need to keep an eye on them because from time to time they will stop pumping and start “choking” but if you leave them alone (or if you need it to work right then, take them out of the water to let it breathe for a split second) they start working again.

      Thanks for the feedback Nick, it’ll help me provide better customer service and support to our future customers. I believe in “under promising and over delivering” the last thing I’d want to tell any of our customer is that one of our products will work for sure if I have any doubts. I’m glad to hear that it’s working for your application.
