Using Thermal Fluid Pumps for High-Temperature Applications


The term “hot oil circulating pumps” refers to a thermal fluid pump. It is the most effective alternative for preventing leaks while also saving a significant amount of energy. For the service of hot oil systems, the pump has been particularly built for this purpose. It is simple to run and has the advantage of requiring little maintenance. These pumps are constructed with heavy-duty bearings that meet or exceed the most recent industrial standard.

In the field of thermal fluid pumps, Sujal Engineering is the industry’s top manufacturer. Our thermal fluid pumps are made of high-quality materials and are the first option for many sectors, including the thermic fluid handling, hot oil transfer, edible oil industry, food industry etc. are using a thermic fluid pump to tackle the issues of circulating the oil. 

Importance of Thermal Fluid Pumps

It is the most important industrial pump in the current time. For many year’s industries 

Including thermic fluid handling, hot oil transfer, edible oil industry, food industry etc. are using thermal fluid pumps to solve the problem of circulation the oil as a part of large boiler feed. A thermal fluid pump is great because it can move a lot of abrasive fluid. This makes this fluid better for use in a heat transfer plant. In order to get a low NPSH and a high efficiency, thermic fluid pumps are made to do this.

Things to Consider While Using Thermal Pumps 

Pumps Specification & Sizing

Many end-users believe that specifying a pump entails selecting a pump that delivers the desired flow and head. There are several forces at 650 to 750°F (343 to 399°C) that can impair pump performance and possibly safety. There is a significant distinction between “will work in this service” and “is well suited for this service.”

So, here are the things to consider when specifying a pump for higher temperatures include:

  •        Casing Design
  •         Impeller design
  •         Material of Construction
  •         Baseplate design to maintain proper alignment
  •         Mechanical seal selection and mechanical seal


Without the proper installation, even the best–specified pumps will not run properly. Here are the things to consider before the installation of thermal fluid pumps. 


Before installing, check the foundation of the pump as, without it, it is baseless. If the base of your pumps is not adequately supported or anchored, then it will not keep it aligned.


The second is alignment. Once the baseplate is level and stable, then aligned it with the motor as per the manufacturer’s recommendation. Remember, laser alignment is more accurate than manual alignment.


Piping is the most important aspect of installation as if your piping is not proper, then it can affect the flow of the fluid. Thus, it is always considered good to evaluate pipe stresses in a high temperature.


Most pumps in 650 to 750°F service have some kind of cooling, very often, it is water cooling. Thus, it is good to practice having an adequate supply of water clean water cooling.  It is also good to have a flow indicator or flow switch to reduce the chance of having the pump run without adequate cooling.


Maintenance is the third and the most important part when it comes to the seamless operation of thermal fluid pumps. These are the things that should be added to a list to maintain the pumps.

  • Pump’s cooling mechanism should be monitored properly.
  • Regular and proper lubrication of pumps.
  • Re-check alignment, and re-align the pumps annually
