In industrial plants, many pieces of equipment or production processes require heating. Plastics-based manufacturing, the processing of wood and forest products, composite processes, chemical processes and similar sectors are areas where this need is high. For heat transfer, thermal (heat transfer) oils suitable for use between 200°C and 350°C are most commonly used, while for lower temperatures, hot water can also be used as the fluid. This oil is heated within a closed system at the plant and delivered to the point of need by means of hot oil pumps.

Since the temperature in these pumps is very high, a special air-cooled zone must be provided between the pump casing and the seal. Thanks to this zone, the temperature of the fluid reaching the seal chamber drops significantly, allowing the use of standard bearings and less costly seals.
Since burn and fire hazards arise during maintenance/fault situations in hot oil pumps, safety precautions must be taken both for the team intervening on the pump and for the surrounding environment. In addition, if fluid at such a high temperature leaks from the pump, a fire hazard arises at the facility. For this reason, the use of external leak detection/prevention devices on these pumps is extremely important.
