In this case study, we focus on the critical role of high-temperature thermal oil transfer and circulating pumps in industrial applications.

Recently, we were approached by a company specialising in the installation of industrial boiler rooms. As part of their regular maintenance and overhaul services, they required five bareshaft thermal oil pumps. These pumps would be coupled with the client’s existing motors for efficient thermal oil circulation.

What is a Thermal Oil System?

A thermal oil system, also known as a thermal fluid or hot oil system, uses  thermal oil to transfer heat to machinery, materials, and various industrial processes.

The system itself is relatively straight forward: a heater warms the thermal oil, which is then circulated through a closed-loop system by a thermal oil pump. As the oil moves through the system, it transfers heat to the processes involved before returning to the heater to be reheated.

It is a much safer method than using steam which is transferred at much higher pressures and temperatures with the associated pipework and accessories requiring much higher investment.

Common Applications of Thermal Oil Systems

Thermal oil systems often rely on high-viscosity and positive displacement pumps, ensuring consistent heat distribution and reliable circulation. One prominent application of thermal oil systems is in tank farms, where large quantities of liquids, gases, or vapors are stored in substantial tanks. These facilities, commonly referred to as oil terminals or depots, handle extremely flammable substances.

In such hazardous environments, air-cooled thermal oil pumps are used to heat tanks and reduce the viscosity of stored liquids, making them easier and safer to handle.

Pumps Tailored to Client Needs

Thermal Oil Pumps smlAt North Ridge Pumps, we pride ourselves on our ability to specify the perfect pump for every application. As the UK’s largest pump supplier, with over 25 years of expertise, we don’t offer one-size-fits-all solutions. Instead, we work closely with clients to determine the most cost-effective and reliable long-term solution for their unique requirements.

For applications like this one, our thermal oil pumps provide safe and efficient heating where direct heat is impractical. We have extensive experience supporting high-temperature operations across industries such as power generation, chemical manufacturing, and food processing.

Our air-cooled thermal oil pumps feature ability to be controlled by variable speed drives, double sealing by Mechanical seal and packed gland, and cooling fins, eliminating the need for external cooling systems. These pumps are designed to meet varying levels of demand while ensuring safe and reliable operation in challenging conditions.

Specifying the Right Pumps for the Job

For this particular client, the requirement was for five bareshaft thermal oil pumps capable of circulating oil at temperatures up to 300°C.

All five pumps we supplied were equipped with self-cooling fins at the rear of the casing, along with a double-seal system combining mechanical seals and gland packing. This dual protection ensures that if one seal fails, the pumps continue to operate without disruption.

The pumps we provided also feature different flow capacities, with some handling 100M³H and others 75M³H, ensuring that the client’s needs were met precisely.
