Chemical Processing Applications and Solutions

150+

Years of technical experience and innovation.

For more than 150 years, customers have relied on Greene Tweed to increase meantime between repair (MTBR) and increase operational safety and environmental compliance.

Our seals, engineered components, and thermoplastic composite wear parts deliver proven performance in aggressive media such as hydrocarbons and aromatics, ethylene oxide, inorganic bases, solvents, steam, oxidizing acids, alcohols, sour gases, and amines. Our solutions are found in equipment commonly used in chemical processing including compressors, pumps, mixers, centrifuges, filtration systems, instrumentation, mechanical seals, and valves.

Expert Application Engineering

Compressors

A Greene Tweed seal in a centrifugal compressor can help increase reliability and efficiency. Our portfolio includes a variety of geometries, including MSE® lip seals, labyrinth seals, and o-rings. Through careful material selection, seals are optimized for chemical resistance and temperature to minimize the likelihood of unplanned downtime. Our elastomer portfolio includes grades of Chemraz® FFKM and Fusion® FKM qualified for rapid gas decompression (RGD) under the ISO 23936-2 testing standard.

Greene Tweed can provide machined Arlon® and Avalon® parts for use in reciprocating compressors. Products include piston and rider rings, valve plates, and valve poppets.

Sealing Solutions for Harsh Chemicals

Aggressive solvents damage traditional solutions and risk premature failure. Optimize performance with our Chemraz® perfluoroelastomers and Arlon® PEEK thermoplastics. They offer near total protection against chemical attack. Even in extreme temperatures and harsh environments.  

Pumps, Cylinder Seals, Wear Rings

Avoid leakage and contamination with our sealing solutions for hydraulic cylinders. Increase productive operating time with safe solutions built from industry experience. We test for relevant operating conditions and engineer our seals to maximize reliability. 

Pumps & Valves

Go off-road knowing your agricultural, construction, and forestry applications are top of the line. Greene Tweed seals prevent leakage, decrease emissions, and avoid internal contamination.

We built our products to withstand a range of conditions. Our engineers select the right materials from our portfolio of elastomers and thermoplastics to make our seals.

Industry-Proven Products

Custom Engineered Sealing Solutions

The most common type of elastomer seal, o-rings provide cost-effective, flexible sealing solutions across a wide range of demanding applications. The o-ring can be used either as a seal itself or as the energizing element in PTFE, cap-type seals.

If you are looking for backup rings, Greene Tweed’s engineers will work with you to develop a custom designed backup ring configuration suited to your needs.

Versatile Sealing for Demanding Environments

Metal spring energized (MSE®) seals are custom designed with a dual-lip body for superior performance in the most demanding conditions. They are built to withstand extreme temperatures, high pressure, and corrosive chemicals found in a aerospace, energy, and other industrial applications. 

Greene Tweed’s selection of MSE® seals are custom engineered to be used across a wide range of industries and applications. No matter how demanding the environment, our team works with you to determine the right sealing solution.

Avoid Damage and Downtime

Greene Tweed thermoplastic composite wear parts are designed to enhance the safety and efficiency of your operations. Lighter and more resistant than their metal counterparts, our engineered components have become the industry standard for refineries, chemical plants, and power generation plants.

Benefits include:

  • Reduced repair and maintenance time
  • Minimized chance of damage to critical components
  • Reduced vibration due to tighter clearance

Reliable Connections in Rugged Environments

Greene Tweed Seal-Connect® electrical and fiber optic connectivity solutions can withstand extreme temperatures, vibration, and shock. We developed our connector portfolio over decades of collaboration with equipment manufacturers, service providers, and operators, leading to over 80 U.S. and foreign patents. On land or offshore, our engineers work with you to determine the best solution for your application.
