Thank you for your input.

In all cases we were using city water at ambient temperature. Let’s call it 70° F and because it is water, the viscosity is at or around 1 cPs.

Thanks!

In some cases where the discharge pressure is very high and forcing internal recirculation you will see cavitation. This is less common, but certainly a very real thing.

Our setup is a closed system so there is a fine line to be able to showcase cavitation in the way we were going for. Adding more water to the tank would absolutely lower the turbulence, increase NPSHa, and decrease the onset of cavitation.

What you are seeing in the setup is a closed loop, but certainly having more water in the tank will mean more NPSHa which will mean a lower chance of cavitation.

Increasing the NPSHa will always be a good way to combat the onset of cavitation.

Thanks for asking! The original manufacturer of the pump was a company out of Denmark called Lavrid Knudsen Mashinkfabrik. Many of the products they made used the initials LK. In this case, the H was added for a high-efficiency product pump.

Glad we could help! :)

We are focused on stainless steel and nickel alloy tube and fittings, so we can not help with copper options. We know they exist in the market, often provided thru brewery and distillery equipment-focused suppliers. It may also be available thru Amazon.

You're welcome!

It is true that air in the system can be problematic. Whenever NPSHa < NSPHr cavitation will occur.

Of course. But if your pre rinse step are to short and not efficient, then caustic solution take back remainings which are stay after pr rinse step. In this case you must often monitor conductivity in the caustic tank and clarity of solution. If you have very good and efficient pre rinse step, caustic will be clear :) Most important thing to use proper temperature in pre rinse solution. Regards and i invitie you to my chanel :)

Just saw that this was never answered. Yes, we reclaim a certain amount of the caustic wash that meets the right conductivity parameters. This fluid is often used in the next cycle's pre-rinse to help aide in organic material breakdown, shortening cleaning times and reducing chemical usage.

Hey, Daniel! There are a couple factors we consider when sizing the CIP vessels. 1. The total volume of the longest line circuit being cleaned by the CIP system. 2. The speed of the CIP supply pump and how quickly it can evacuate the CIP tank. 3. The rate of the makeup water as compared the CIP supply pump. If the supply pump can outrun the rate at which the makeup water can replenish the tank, then it will need to be sized larger to account for that additional loss.

Also, an additional thing we look at is space available and passage into the building. Sometimes we have to make adjustments to get the tanks into the building. Lastly is future-proofing. If they have space often a bit larger tank is not much more money. Gives them room later if they add circuits to the system.

Yes! We would recommend the TrueClean® CIP'able Air Blow Check Valve, which is the first and only sanitary air blow check valve that can be cleaned in place within a process line. You can learn more about this valve here: www.csidesigns.com/products/valve-systems/valves/check-valves/cipable-air-blow-check-valve or you can always give us a call (1-417-831-1411) and we would be happy to answer any questions you might have!
