What is the best pump for high temperature liquid transfer in home beer brewing?

In summary, the conversation is about home beer brewing and the need for a pump to improve the cooling process. Suggestions are given for a suitable pump, such as a stainless steel diaphragm pump or a Stainless Steel Taco 007 circulator. The use of gravity feed and a cooler or immersing copper tubing directly into the wort are also discussed as alternative methods. The thread provided also has additional advice and solutions for cooling the wort.

I have recently gotten heavily into home beer brewing with some people. To improve on the cooling of the wort (boiled beer before fermentation), I want to pump the boiling liquid through a long copper coil. This coil will be inside a cooler filled with ice and the cooled wort will come out on the other side.

In order to do this I will need a pump that accepts high temperatures ~100 degc and have enough pressure to push through the copper coil of somewhere around 20-40 feet. The flow rate doesn't need to be that high considering that the wort needs to be fully cooled when it exits the system. Does anyone have any suggestions or input as to a good pump that will do this.

I'm not looking to spend a ridiculous amount of money either. Just something to get the job done. Any help is greatly appreciated!

If you have an air compressor, a simple stainless steel diaphragm pump will work. If you use a centrifugal pump, you may need to flush the mechanical seal at this temperature.

Why not have your hot tank higher then your cold tank and get gravity to do the job for free?

Here's a pump from a local homebrewing supplier. There are numerous online suppliers where you might be able to find it cheaper, but I use them because they're local to me. The searching is up to you though.

Other than that, you can use gravity feed and a cooler, or instead of running the wort through the copper tubing, immerse the copper tubing directly into the wort towards the end of the boil. When you're ready to cool you can run tap water through the copper tubing. Using 40-50' you should be able to cool a 5 gallon batch quite quickly (10 minutes or so even with warmer tap water). Personally I'd rather not run the wort on the inside of the copper tubing either, as it could be difficult to clean and much more prone to fouling/buildup that way. With the pump it may not be much of a problem, but still.

This thread also has some advice in it, or you can post your own questions and I'm sure somebody will answer.

Thanks for the replies! Our original way of cooling is by immersion of a copper coil with a hose connector. It works no problem, but were hoping to improve cooling and speed up the process by cooling and transporting the wort at the same time. It would save a lot of time, energy, and potential infection of the beer due to oxidation.

As for that march pump, I have been looking into it already. I'm just not sure if I want to put the money in... :redface:

If you have a hydronic heating supplier in your area, a Stainless Steel Taco 007 circulator will do what you wish for around $100. In the plumbing and heating world, we use these circulators to move hot potable water from tank to tank or recirculate through a system. They can withstand the temperatures that you wish and can be easily controlled. They operate on 120VAC and use about the electricity of a 75 watt lightbulb.
 

1. What is a high temperature liquid pump?

A high temperature liquid pump is a type of pump that is specifically designed to handle liquids that have a higher temperature than what traditional pumps can handle. It is typically used in industrial settings where the liquid being pumped may be heated, such as in chemical or manufacturing processes.

2. How does a high temperature liquid pump work?

A high temperature liquid pump works by using a motor to create a rotational force that drives an impeller. The impeller then rotates and creates a centrifugal force, which pushes the liquid through the pump and out through the discharge outlet. This process is repeated continuously to pump the liquid at a high temperature.

3. What types of liquids can a high temperature liquid pump handle?

High temperature liquid pumps are designed to handle a wide range of liquids, including water, oils, chemicals, and other industrial fluids. These pumps are able to handle liquids with temperatures ranging from 100°C up to 500°C, depending on the specific model and design.

4. What are the benefits of using a high temperature liquid pump?

The main benefit of using a high temperature liquid pump is its ability to handle liquids at extremely high temperatures. This makes it ideal for use in industrial processes where high temperatures are necessary. Additionally, these pumps are often more durable and have longer lifespans than traditional pumps, making them a cost-effective solution in the long run.

5. How do I choose the right high temperature liquid pump for my needs?

When choosing a high temperature liquid pump, it is important to consider the type of liquid being pumped, the required flow rate and pressure, and the specific temperature requirements. It is also important to select a pump from a reputable manufacturer to ensure quality and reliability. Consulting with a pump specialist can also help in selecting the right pump for your specific needs.
