CHESTERTON - Packing for rotating Equipment

Depending on the application, specific packings are available for use with water, steam, chemicals, waste water (sludge, dewatering) and for the food industry.

Criteria for choosing the right packing are, for example, the maximum permissible pressure, pH value, material properties, operating temperature range, running performance in m/s and, of course, the range of external dimensions on offer.

Equally important is the general reliability, economical operation of the applications and the respective permissible emission values.
