Heat Transfer Applications for Our Pumps
Heat transfer is the movement of thermal energy, depending upon temperature and pressure, from an area of low temperature to a higher temperature area. Using kinetic energy produced by impellers, centrifugal pumps increase the fluid pressure and then discharge the fluid through the outlet. The result is that heat transfer systems pull heat from one place to discharge it in another and vice versa. Heat transfer pumps have numerous applications in both industrial and consumer contexts, including refrigeration, heating, and energy efficiency.

Choosing a Pump for Heat Transfer
Because heat transfer pump applications involve the moving of some sort of liquid at relatively high temperatures, selecting the correct pump is important. Leaks are always a risk in a heat-transfer system, and while they often depend primarily on factors such as piping and system design, selecting the correct pump will go a long way toward ensuring that issues don’t arise. Some factors you should consider when choosing a pump for heat transfer include:
- Fluid Properties. While water and air are commonly employed in heat-transfer systems and pose little risk, some end-use applications require more potentially problematic substances such as silicones, hydrocarbons, ammonia, and more. Ensure that your pump can handle your specific fluid without corroding. Additionally, ensure that the pump can move the fluid at its more viscous ambient temperature rather than just at its hotter output temperature.
- Temperature. Similarly, different fluids can contain different amounts of heat, and you must ensure that your pump is constructed out of materials that can tolerate higher temperatures.
- Pressure. While centrifugal pumps perform well at a variety of pressures, higher PSIs may cause efficiency to drop. However, most heat-transfer systems will function at around 50 PSI, a pressure at which centrifugal pumps work well.
- Horsepower. Your final consideration should be the horsepower required to move the liquid through the heat-transfer system in an efficient manner.
Heating and Cooling of Buildings and Vehicles
Heat-transfer pumps are a major component of HVAC systems, and smaller options are often used in automobiles. Heat-transfer systems can either warm or cool spaces depending on their configuration, and heat-transfer systems can source or dispose of heat from a number of sources, including:
- Natural Gas
- Solar Power
Water-heating heat-transfer systems work on the same principle as those that heat or cool buildings: They draw higher-temperature liquids from warmer areas and move them to those that are cooler. In systems designed to heat water, they funnel heat to a water-storage tank.
In industrial settings, heat-transfer systems can greatly increase operational efficiency, with some systems repurposing waste heat in order to warm the facilities. Given the incentives to follow environmentally friendly practices and the great amounts of heat generated by many industrial processes, the installation and maintenance of a heat-transfer system can quickly pay for itself.
March Centrifugal magnetic drive pumps are the top choice for applications in heat transfer. Built to withstand harsh conditions, March pumps can potentially tolerate liquid temperatures of 190 Fahrenheit or 87 Celsius. The pumps are capable of generating a maximum flow of 2.7 gallons per minute at 1 foot, and a maximum head of 10.6 feet. Industrial strength construction protects against highly corrosive acids and solvents.
