Sealing systems built for Chemical Industries

The Chemical Process Industry (CPI) is the broad industrial market that converts raw materials into chemicals, fuels, polymers, specialty materials, and other processed products through chemical reactions, separation, heating, cooling, mixing, compression, and fluid handling.

Chemical Solutions

CPI plants are highly equipment-intensive. Typical facilities contain large numbers of pumps, valves, compressors, reactors, pressure vessels, mixers, heat exchangers, piping systems, filtration equipment, and instrumentation. Much of this equipment operates continuously and handles corrosive, hazardous, high-temperature, or high-pressure fluids.

CPI Operations

CPI plants are highly equipment-intensive. Typical facilities contain large numbers of pumps, valves, compressors, reactors, pressure vessels, mixers, heat exchangers, piping systems, filtration equipment, and instrumentation. Much of this equipment operates continuously and handles corrosive, hazardous, high-temperature, or high-pressure fluids.

Chemical resistance

CPI media range from strong acids and caustics to solvents and chlorinated compounds. Seal elements come in PTFE, evolast® FFKM, FKM, and EPDM so material matches the fluid and temperature instead of one compound covering every service.


Temperature and pressure

Reactors, heat exchangers, and pumps see wide thermal cycling and pressure swings. Spring-energized designs hold contact force from cold startup to full operating temperature, resisting extrusion and compression set where standard elastomers fail.



Containment and uptime

Leakage in CPI is a safety and emissions issue, not just maintenance. Low-friction lips and consistent sealing force reduce fugitive emissions, extend time between shutdowns, and support compliance in continuous-duty equipment.
