Pumps for Vacuum Drying
Heat transfer pumps
Vacuum pumps
The application
Vacuum drying is a process of removing moisture from products which are often thermally sensitive and degrade when heat is applied. Consequently, these products are dried under vacuum in order to reduce the boiling point of the surplus liquid. Drying at reduced temperature means that product quality is maintained while evaporation rates are enhanced.

Heat transfer pumps: Heat is required to facilitate the evaporation and drying process
because evaporation causes cooling. Supplying the heat is achieved by circulating hot
thermal fluid around a closed system. A specific design of end-suction centrifugal pump
is employed for this duty in which to provide operational safety, environmental security,
and long-term reliability.
