Quick Overview of Flojet Beer Pump

This video goes over some brief points regarding a beer pump in a commercial draft beer system. I talk about how it functions. The gas/air that's used to power the pump. How to clean and maintain the pump. You'll also see why I prefer this over using blended gas on beer systems.
Here's a blog post on my website where I talk about Flojet Beer Pump

Hey Kyle, great video. Thank you for the information. I recently began working at a bar and someone had already setup the flojet with a mixed gas setup. I am trying to wrap my head around it. What the installer did was adding a splitter to the keg coupler. One goes to a direct draw system on the same floor and the other end goes into a FOB through a flojet which pumps beer to the floor beer (I don't know why they added a pump for a gravity fed system as well). But now I am trying to balance lines through all this and man am I having a hard time. Do you think getting rid of a splitter would help? Additionally, would adding a splitter at the end of the FOB help? Thank you for the comments.

Hi Kyle - Thanks for the video. I'm getting ready to install taps to my second bar area. It's about a 25 foot run tops. Anyway reading the documentation on the FLOJET pump it states.
"The operating pressure to the pump is used to control
the flow rate. Due to the pumps powerful hydraulic push
against the beer, the system must be considerably over
restricted. Use the following as a general guideline:"
For 3/8" ID Trunkline
• Up to 100’ length, use 13 feet of 3/16" choker line
My question is where is the choker line located or is the proper pressure to the pump better achieved using a dedicated regulator.
Thanks

what is the relationship between the pump operating pressure, line length & ID, and dispensing flow rate?
I have a 55 foot length lines, 3/8 id. And would like to keep flowrate at or near the recommended 1 gpm.

[@kylerenstrom1342]

Pump pressure will be determined by the length of the beer run, ID of the line and material of beer line. I usually start with the I.D. measurement and work from the beer cooler to the dispensing tower. The ID of lines will give you a restriction value by foot. Vinyl ID is .20 per foot and Barrier is .06 per foot. Once you have this restriction value you use this for the length of the beer run. Remember, Vinyl, Barrier tubing and SS have different restriction values. So you will need to make sure you're using the right value for the right length and right material. From the information that you gave me off the cuff I would set the pump pressure to 20 PSI and check the flowrate at the beer faucet. If the flow is not enough and would bump it up until the 2 oz per second is achieved. That pressure should put you in the ball park. Cheers

@@kylerenstrom1342 Thanks Kyle. One follow up Q: Will a lower than "design" pressure produce less flowrate or less flowrate AND foamy pour? Is the pressure loss from the line length enough to get co2 out of solution (in a flojet pump installation)

[@kylerenstrom1342]

Jorge Delgado it will be a a lesser flow rate and potentially foaming beer... because applied pressure won’t equal the restriction value of the system. However this is for a small amount of time until the flow rate is achieved through pump pressure.As far as beer losing CO2. I wouldn’t expect that to happen because. The keg pressure is controlled by a separate regulator inside the walk-in cooler and is only catching a ride from the beer pump to a draft tower.
