Further applications
Optical machines
Spandau Pumpen offers an outstanding solution to the pumping tasks faced in optical machines, such as those used in the manufacture of corrective lenses; special lenses for night vision equipment or binoculars; telescopes; photographic equipment and precision lenses.
Spandau centrifugal pumps are used in the processing of glass and plastics. Their high reliability when pumping emulsions and oils for sawing, polishing and grinding make them a strong component in any optical machine.
Polishing and grinding emulsions are used in machines for grinding and polishing. The particles are very fine but highly abrasive. In other words, all parts of the pump need to be made of resistant materials such as plastic or stainless steel.
Temperature control and cooling units
Temperature control means bringing a medium to a certain temperature and keeping it there. The process goes in both directions, cooling and heating. Some manufacturers have specialized in cooling, some in heating. However, the trend today is towards building combination units that can be used for both cooling and heating. For example, in the case of temperature control of injection molding tools, the mold is first heated; the plastic is introduced into the mold, and then the process is put in reverse. In other words, the mold is cooled down.
The number of manufacturers offering these kinds of devices has been growing strongly for several years with many new small- to medium-sized companies coming into being. This is because the technical processes in many industries are changing so that an additional cooling step is necessary.
The cooling capacity of the units ranges from a few kW up to several hundred kW. That explains why so many different pump models (in terms of rated power) are required.
