Chemicals - Pharmaceuticals > Conveying equipment

Pumps and fittings used in the chemicals and pharmaceuticals industries generally have to meet high requirements with regard to the resilience of those equipment components in contact with the product when exposed to chemicals, temperature and pressure. In many applications, for cost-efficient operation, the use of oxide and non-oxide ceramic components such as Al2O3, doped ZrO2, Al2O3-ZrO2 mixed ceramics, SiC or Si3N4 is often the ultima ratio.

The following overview lists general technical data of such materials that recommend their use in the chemical and pharmaceutical industries:

  • Purity: >99,5 %
  • Density: >98 % of the theoretical value
  • Thermal strength to the region of 2000 °C
  • High shape and dimensional stability at high temperatures
  • High thermal shock resistance
  • High resistance to abrasion
  • High resistance to cavitation damage
  • High resistance to corrosion when exposed to melts, acid and alkaline solutions and gases
  • Leak rate for He: <10-9mbar*L/s
  • Specific electrical resistance: >1014 Ω*cm
  • Not magnetizable
  • Regulatory approval for direct contact with foodstuffs
  • Realization of leak-proof sealing systems without additional components
  • Suitability for force, form-fit and substance-to-substance ceramic-ceramic and ceramic-metal bonding
