In industrial factories, many equipment or production processes require heating. Plastic-based production, processing of wood and forest products, composite processes, chemical processes, etc. are the areas where this need is intense. Heat transfer oils suitable for use between 200°C and 350°C are most commonly used in heat transfer. For lower temperatures, hot water can also be used as a fluid. This oil is heated in a closed system at the factory and delivered to the point where it is needed through hot oil pumps.

Since the temperature is very high in these pumps, there must be a special air-cooled area between the pump body and the seal. Thanks to this area, the temperature of the fluid reaching the seal area drops significantly, allowing the use of standard bearings and less costly seals.
Since there is a risk of burns and fire in cases of maintenance / malfunction in hot oil pumps, safety precautions must be taken for both the team that will intervene in the pump and the environmental environment. Additionally, if fluids at such high temperatures leak from the pump, there is a risk of fire in the facility. Therefore, the use of external leak detection / prevention devices in these pumps is extremely important.
