Pumps for high temperature use

Heat transfer oil plants are used to indirectly temper processes in production. In these plants, a fluid – such as thermal oil –  is utilized to transfer heat. The thermal oil makes it possible to heat or to cool objects or substances during a process. Unlike the use of water as a heat transfer medium, thermal oil can be used to guarantee system operation up to 350°C, even without pressure. In addition, there is neither corrosion nor the danger that the plant could freeze in an outdoor installation.

The heat transfer technology comprises together with the heat transfer oils a very wide range of production processes. The oils are on a mineral or synthetic basis, and can be heated up to 450°C. At such high temperatures, this happens at a pressure of about 12 bar. Typical applications for the canned motor pump include circulation pump the chemical, petrochemical, refinery and energy utilities. Thus, the pump forms the core of a single heat transfer circuit, which is used for indirect temperature control.
