BATCH OPERATION B017
A batch operation means that the product is manufactured in small quantities as opposed to a continuous operation where the equipment operates for twenty four hours.
These batch operations can cause many sealing problems because of some product’s tendency to crystallize, solidify, become viscous, etc. during the time interval between batches.
The cleaning that goes on between batches is another source of potential sealing problems, because of the cleaning steam or solvents that can attack the mechanical seal’s elastomers. (O-rings).
