FEATURES & BENEFITS
- Reliable operation resulting from advanced volute groove design and internal circulating devices that promote cool running
- Longer service life via a stationary face support drive mechanism that reduces wear in applications with high vibration levels, and springs and pins outside the process for reduced corrosion and clogging
- Application flexibility with double-balanced seal face geometry, allowing both pressurized and unpressurized operation; ISC2-682PP provides full API 682 compliance
The Series 80 seal is one of Flowserve’s Heritage products that has a proven track record of performance. Built with premium materials, this Stationary designed, Hydraulically balanced seal succeeds in the most challenging applications.
Flowserve spun off the more popular sizes of the Series 80 and formed the CPM seal which allows us to compete with today’s low cost seal manufacturers. The CPM line of seals are used for competitor change outs in general service applications. Compared to other light duty seals, the CPM seal weights 30% more due to the heavy duty gland design. The flush port is also larger than most light duty seals making the CPM seal a better all-around choice.
SPECIFICATIONS
Press. to vacuum to 400 psig (27 bar)
Temp: -40 to 400 F (-40 to 204 C)
Speeds to: 100 ft/min (30m/s)
Sizes: 3/4″ to 3.750″
FEATURES & BENEFITS
- Robust rotary face design is flexibly mounted, enhancing the ability to survive shock and face distortion typically found in clamped seal face designs.
- Springs located outside the process fluid deter chemical stress corrosion and spring clogging by dirty process fluids.
- Hydraulically balanced seal design reduces friction, heat and wear with lower loading forces while maintaining a lubrication film between the mating faces.
- Floating stationary to accommodate out-of-square pump misalignment.
This single, unbalanced, multi-spring component seal is usable as an inside or outside mounted seal. Suitable for abrasive, corrosive and viscous fluids in chemical services.

Speeds to: 23 m/s (75 fps)
Shaft Sizes: 9.5 to 115 mm (0.375 to 4.500 in)
FEATURES & BENEFITS
- Increased durability from robust rotating spring compression unit that helps to keep solids away from the seal faces and removes seal-generated heat
- Improved reliability with rotating seal ring that is independently centered on the shaft and has multiple springs and drive pins that evenly distribute the load
- Broad application flexibility enabled by completely interchangeable shaft packing materials, dimensionally interchangeable insert mounting, and compression unit availability in any machinable metallurgy
The CRO is an economical, single-coil spring, friction drive component seal for use in pumps with packing box seal chambers. Available in single or dual arrangements.
