How the Right Brewery Pump Seal Can Solve These 3 Costly Problems

Whether you're a microbrewery creating craft ales, a big commercial brewery, or simply have a home brew pump to make your own beer at home, you are likely to experience some common Brewery Pump problems caused by having the wrong pump sealing. So, have you been experiencing leaks when transferring hot wort?

In our dealings with brewers, we found that many are unhappy with the life span of their brewery pump sealing. We discovered that the hot wort from the brewing process damages many pumps as the sugar compound contained within alcoholic liquids builds up around the mechanical seals and crystallises. This consequently results in stress corrosion cracking and the seal leaking, which causes the beer transfer pump to leak and damage the motor. So, to save you time, money, and lost production, we have shortlisted 3 costly problems that you are likely to experience if you do not have the right Brewery Pump sealing and provide a simple solution to solve these issues.

Common hot wort transfer pump problems you might experience

Over the past few years, we have seen many clients from the brewery industry experience the same problems with beer wort pumps. However, many don’t understand what is causing it, and as a result, they don’t deal with the root of the problem. So here are 3 costly problems that the wrong seals on a beer transfer pump can cause.

Leaks and mess – If you are experiencing brewery pump leaking, you are probably having a problem with the pump sealing. As the sugars produced by the hot wort is crystallising on the faces of the mechanical shaft seal and forcing the two components apart, the beer transfer pump will start to leak. This will result in fast and frequent corrosion and messy leaks, which are hazardous and take time to clean up.
Damage and downtime - Beer wort pumps are a crucial part of the brewery process; having to stop using the pump until the leaks are repaired may result in production stopping. This results in the costly loss of productivity, time and potential waste of product when your beer production comes to a halt.
Cost of maintenance, excessive spare parts and repairs – Although having a brewery pump maintenance plan is key to keep your pump running smoothly, not having the right brewery pump sealing can cause unexpected maintenance and repairs. As the hot wort starts corroding the pump seals, you’ll need to spend time and money to keep replacing them, and this will result in the excessive buying of spare parts. Hot wort transfer pump leaks could also cause damage to other parts of the pump, which will require costly repairs and ongoing maintenance.

Finally, a solution to your beer wort pump leaks!

If you are experiencing leaks when transferring hot wort and your brewery pump seal looks like this, we have a solution for you.

After working closely with the brewery industry and testing different brewery and home brew pump seals, we found a mechanical seal with a material that will withstand the high temperature but does not allow the sugar to adhere to the mating surfaces. After discovering this special beer transfer pump seal, we started supplying the seal pre-attached to our Lowara CEA(M) and Ebara CDX(M) brewery pumps, and we also stock the seal as a spare part for retrofitting to existing Lowara and Ebara pumps. This unique hot wort transfer pump seal has helped many of our clients forget about pump leaks and these common pump problems.

Don't just take our word for it. After we started supplying this simple but effective solution for brewery pumps, we were flooded with positive responses from brewers who say...

"After experiencing the same problem year after year, I thought my system would never work effectively. That's until I installed Whisper Pumps CDX Brewery Pump, since then my system has never worked better.

I've saved time and money!"
