When is a High Temperature Pump Important to Your Operation?

You have a problem. You need your fluid pumped quickly, efficiently, and safely from one place to another. But it is not just any fluid. It is a high temperature material that cannot be safely transferred using a standard pump without becoming a hazard to your building and the people working in it. You are going to need a high temperature pump in this scenario. No need to worry, because once again the team at ESP can assist in meeting your specific needs. Do not hesitate to contact us with any questions you may have about our equipment and services.

One of our manufacturers, Dean Pump, is a leading global provider of top quality high temperature pumps that are specifically designed to handle corrosive, abrasive, and high temperature fluids.

Let’s dive a little further in to see which high temperature pump is right for you and your company’s goals.

What is a High Temperature Pump?

A high temperature pump is actually exactly what it sounds like. This type of pump is designed to transfer fluids at high temperatures. Simple enough, right? Introducing hot fluids into a pump that is not meant to handle them can cause a variety of problems for the equipment. Along with being a potential hazard to people that work near the equipment. Doing this can cause anything from leaky gaskets to shattered or split pump casings. This is why it is important to choose the correct equipment for your application, and ESP is more than happy answer any questions that you may have during the process.

Common Applications of High Temperature Pumps

It is important to understand the different reasons why liquid may need to be moved at a higher temperature, which requires special equipment. It is not always as easy as cooling the liquid back down so it can be used in a standard style of pump. In certain situations, it is not possible or economical to avoid high temperature pumping. So we must accommodate in order to get the job done.

One reason is if the hot fluid is being used to transfer heat. Liquid is a popular way to control temperature because it is reliable, easily controlled, and economical. Here are some examples of industries that need high temperature pumps for their heat transfer operations.

-        Pharma manufacturing

-        Food processing

-        Chemical manufacturing

-        Candy making

-        Snow removal

-        Plastic manufacturing

Another reason that liquids need to be pumped at higher temperatures is if the they are by products of a process or reaction that generates lot of energy in the form of heat. While this hot liquid is being formed as a result of the reaction, it will need to be transferred to its new desired location. Again, this will have to be done using a high temperature pump. A few examples of this situation include…

-        Solvent extraction

-        Cracking refineries

-        Blending facilities

-        Chemical mixing

-        Distilling

-        Asphalt blending

A third reason why liquids must be moved using a high temperature pump is when the material actually takes on a solid state at room temperature. In order to pump this material, it needs to be heated to its melting point so it can be easily moved from point A to point B. Listed below are a few different materials that require heating before they can be transferred via pumping.

-        Asphalt

-        Molasses

-        Tar

-        Sulfur

-        Lead

Now that you have a better understanding of why high temperature pumps need to be used and the different industries they are commonly seen, let’s take a look at some of the different styles that are offered by a manufacturer such as Dean Pump.

High Temperature Pump Designs

In order to serve your needs to the best of our ability, we like to explain a few options and the highlights of each design.

Dean Pump RA Series Air Cooled Thermal Liquid/Hot Oil Pump

This is the most cost effective heat transfer pump design that features a shaft mounted fan to provide air flow which helps to cool the pump. No water is required for cooling and this can pump liquid at temperatures up to 650 degrees Fahrenheit.

Dean Pump RWA Series Air Cooled Hot Water Pump

These are designed to be used with hot water, ethylene glycol, propylene glycol, and triethylene glycol in multiple heat transfer applications. Again, a fan will provide air flow to the cooling fins of the pump and it does not require any water to provide cooling. This design is rated for pumping operations up to 400 degrees Fahrenheit.

Dean Pump RAV/RAW Series Air Cooled Vertical Inline Thermal Liquid/Hot Water Pump

Both of these designs also feature a shaft mounted fan to provide cooling and pumping temperatures up to 650 degrees Fahrenheit. These are commonly used in industries such as hospitals, universities, laundries, and prisons.

Dean Pump RMA5000 Series Magnetic Drive Air Cooled Process Pump

This is another air cooled design but it differs in the fact that it is capable of being water cooled as well. With pumping temperatures up to 750 degrees Fahrenheit, this high temperature pump is popular in chemical processing, petrochemical, power plants, plastics, heat transfer, pharma, and food processing.

Dean Pump Heavy Duty High Temperature Pumps

These heavy duty pump designs are similar to the other models but they can handle higher temperatures and more corrosive materials due to their stronger construction. Depending on the situation, it may be a good idea to consider a heavy duty style of high temperature pump.
