Hot Oil Pumps for Thermal Fluid Heating Systems Request a Quote

Thermal Fluid Systems, Inc. specializes in the design, supply, and servicing of hot oil systems, also referred to as thermal fluid heating systems for the process industries. Our services include complete system design and supply, as well as parts supply and maintenance throughout the life span of the system. The systems we offer are expertly designed and serviced to produce consistent and high-temperature heating at low pressures

We offer a wide range of replacement parts— including pumps, valves, burners, control panels—not only for our own thermal fluid systems but for other manufacturers’ systems including Geka, GTS, Konus, Eclipse and Fulton among others.

Hot Oil PumpsThe types of high temperature hot oil pumps we supply include:

  • Mag-drive pumps
  • Canned motor pumps
  • API pumps
  • Mechanical seal type pumps

And we carry top brands including KSB, Sihi, Allweiler, Dean, Kontro, Dickow and more.

What Types of High Temperature Pumps Are Available for Hot Oil Systems?

Selecting high-quality pumps and replacement parts from a reliable manufacturer helps keep hot oil systems working properly and smoothly

At Thermal Fluid Systems, we can source pumps and parts from major manufacturers and customize your systems to use one type of pump throughout the facility. Available for fast delivery and installation, our inventory includes the following pumps:

Hot Oil Pumps For Thermal Fluid Heating Systems


Magnetic drive pumps—also commonly referred to as mag-drive pumps—use magnets to rotate the internal impellers that push fluid through the hot oil system. The use of magnets removes the need for external shafts and their accompanying seals, which eliminates the risk of leakage. This characteristic makes this type of pump ideal for systems that have expensive, corrosive, or toxic fluids that must be prevented from leaking out of the system as either a liquid or gas.

Mag-drive pumps have several advantages, including:

  • Low risk of leaks: These pumps don’t have external shaft components, which eliminates many of the potential leak vulnerabilities possessed by other types of pumps. These pumps are also tested to reduce the risk of fluid (either gas or liquid) leaks.
  • Low cost of maintenance: Mag-drive pumps require very little maintenance throughout the life span of the system. While the power requirements may cost more than comparable pump systems, that expense is largely negated by the lack of maintenance and repair costs.


Canned motor pumps serve as an alternative to magnetic drive pumps. These pumps similarly do not rely on mechanical seals and offer a low risk of leakage when employed, as the moving pump parts are contained within a hermetically sealed chamber. Typical applications include use in systems that need to guarantee zero leakage, such as systems with expensive fluids, systems with radioactive or toxic coolants, and any system with corrosive fluids.

Some of the other advantages of using canned motor pumps include:

  • Reduced noise: These pumps operate more quietly than other hot oil system pumps.
  • Explosion-proof and airtight parts: Designed to handle pressures that are greater than is attainable by most systems, the seals on canned motor pumps are airtight. These qualities also contribute to the leak proof guarantee.
  • Space efficiency: These pumps are available in a compact design. Because the motor and pump components are contained within a joint unit, canned pumps require half the space or less of comparable sealed pumps


API pumps are designed to meet the American Petroleum Institute (API) standards for hydrocarbon pumps. Specifically, API pumps meet the API 610 standards for centrifugal pumps that are rated for high-pressure conditions, such as are found in the petroleum, petrochemical, and natural gas processing industries. These pumps are built with durable pump casings that are designed to withstand high pressures and temperatures; Qualities which help to prevent explosions and reduce the need for frequent servicing or maintenance of the pump.

ANSI pumps are another type of process pump which is designed to meet the ANSI, or American National Standards Institute, standards. However, these pumps are built for systems that handle thin liquids such as water and alcohols. API pumps, on the other hand, are built to handle viscous hydrocarbons without cracking under the increased pressure. Common applications for API pumps include oil refineries and other processing plants along oil supply chains.


As suggested by the name, mechanical seal type pumps utilize a mechanical seal that acts as a check valve and slider bearing for the pump. This component prevents fluids from leaking out of, and air from leaking into, the pump during operation. However, through regular use, it experiences wear, and eventually fatigue, necessitating replacement of the seal component.

TFS, Inc. also offers mechanical seal pumps that are available as air- or water-cooled.
