The temperature of a medium affects its physical and chemical properties and those of the material of all wetted parts in the pump. Therefore the knowledge of the temperature is essential to select the suitable pump types, materials and to define tolerances.

The influence of temperature on media and pump selection
The changes of the physical and chemical properties caused by the change of temperature can sometimes be reversed, sometimes not. Therefore it is often critical to secure a constant temperature of the media throughout the conveying process to maintain the product quality. Pumps can therefore be equipped with heating or cooling devices.
On the other hand media is often pumped with changing temperatures. It is important to know this temperature range to calculate tolerances or to include monitoring and setting devices which allow to adapt to the media changes to ensure safe and reliable conveyance. It is therefore important to select a pump type that is suitable to adapt to the changing conditions.
