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.
