The Flowserve ISC2 Series is a complete family of mechanical seals that provide exceptional reliability and standardization over the widest variety of industrial applications and equipment. ISC2 seals meet all major international standards and are designed for hundreds of pump models from global manufacturers. Facilities will immediately benefit from less inventory, greater flexibility, less downtime and longer seal life.

Advanced technology semi-cartridge split seal for pump and mixer applications. The PSS 4 split seal, with intrinsic joint alignment technology, provides the easiest and most successful installation routine to make reduced equipment downtime and increased reliability... routine.

Circpac MD seals are a segmented circumferential seal designed for fans, blowers, dryers, turbines, centrifuges and other rotating equipment. Circpac MD seals come packaged in a convenient split housing for easy installation. Standard designs consistently outperform packing, bushings, labyrinths, and felt seals with lower gas consumption over a wider range of operating conditions.

Pac-Seal elastomeric bellows component seals are designed to meet a wide variation of applications.

Flowserve believes seal excellence starts with superior design and materials. That's why Pac-Seal mechanical seals are made with using the latest engineering technology to analyze and design solutions for our customer’s most challenging applications. Our experience with diverse materials including elastomers, plastics, exotic alloys and seal face materials makes Pac-Seal mechanical seals an industry leader focused on total cost of ownership.

Dry running, non-wearing, non-damaging and low maintenance seal for powder and bulk solids handling equipment.

The PSS 4-61 split seal has undergone rigorous testing and evaluation by NSF International and has been NSF/ANSI/CAN 61 & 372 certified for applications that involve drinking water, from the source to the tap. The NSF certifications cover all wetted components of the seal and demonstrate how PSS 4-61 seals meet regulatory requirements for drinking water quality, giving municipalities confidence in safe seal selection and operation.

GLS, GSS, and GSG Series seals are designed to fit the unique installation envelop and operating speeds present in integrally geared pumps and compressors. GLS seals are suitable for operating on liquid, whereas GSS seals are designed for operating in gaseous environments. GSG seals are applied at the bottom of vertical gearboxes to seal gearbox oil in and keep contaminants out.

The PL-Series of seals are pre-engineered single and dual cartridge seals with nonmetallic wetted components for use in highly corrosive chemical services where the alternative cost of high alloy metal seals is prohibitive.

The LS-300 cartridge multiple dynamic lip seal is for highly viscous applications. It is designed to run dry without the need for an external flush or lubricating barrier fluid which can contaminate or dilute the process media.

The advanced GTS seal is designed to handle real world steam applications providing the benefits of a mechanical seal in sealing steam turbines.
