Thermal oil



Thermal oil

Thermal oil is a highly suitable – and safe – alternative to steam in many processes, particularly where the dangers of high pressure are to be avoided. Grundfos' range of feeding pumps for thermal oil applications handles temperatures up to 240°C.

Energy consumption is important to your customer.Grundfos' high-efficient E-solutions significantly reduce energy consumption by automatically adjusting pump performance to the actual need. Naturally, the E-solutions meet international efficiency standards.
Stock management can be difficult due to the global differences in voltages and frequencies. Grundfos' E-solutions feature dual frequency and a wide voltage range, allowing you to use the same solution all over the world. Naturally, the E-solutions carry the necessary approvals.
The very high temperature of hot liquids can be damaging to the pump and even destroy the shaft seal.Grundfos offers specially designed shaft seals that handle liquid temperatures up to 240°C, including thermal oil without external cooling.
When temperature control is part of the process, the pump material is potentially stressed because of the continuous thermal expansion and contraction. By applying one of Grundfos' speed-controlled pumps the temperature is held constant.

Important notes

Depending on the type of oil used in the application, different rubber materials are available:

  • FKM: Viton
  • FXM: Fluoraz
  • FFKM: Kalrez
