Pump, bearing and valve impregnation is often used to seal porosity making your items fit for purpose.
- Sub-surface sealing in food and pharmaceutical process parts where micro porosity could harbour contaminants. Methacrylate sealants are insert in the ‘cured phase’ providing the ideal solution as 100% cleanliness is the operating standard
- Process valves and pumps – high pressure and aggressive mediums often mean pump manufacturers turn to porosity sealing 100% of the time
- Engine cooling pumps
- Fire hydrant systems
