Products – Heat Transfer Pumps
In the temperature range up to approximately 200 °C, water is the preferred medium as it is non-polluting and has a high specific thermal capacity. In the temperature range from 200 °C to 400 °C, organic heat transfer liquids are preferable because the vapour pressure also rises considerably when the temperature increases. For handling these heat transfer media, volute casing pumps have been specially developed.

Products – Liquid Ring Compressors
Liquid Ring Compressors compress gases from a lower pressure to a higher pressure. Almost all gases and vapours can be compressed, even those containing dust and liquids. Due to the intensive contact between the gas being conveyed and the operation fluid, there is only a very slight rise in the temperature of the gas being conveyed, so that one can almost describe it as an isothermal compression.
