2.5.2 Application notes

In recent years, screw pumps have been replacing oil-lubricated rotary vane pumps in the high pumping speed segment (100 – 600 m3/h)

Their advantages include:

This makes HeptaDry screw pumps very well suited for chemical applications or processes that generate dust, e.g. for semiconductor production, or if significant volumes of condensate are produced.

In connection with thermostatic cooling, the water flow volume will depend upon the following parameters: Inlet pressure, gas type, rotary speed and pump size. Because of the waterflow cooling, virtually no heat is dissipated to the atmosphere. This can ease the heat load on any existing air conditioning systems and reduce their energy consumption.
