Compressor
Centrifugal compressors and other turbomachinery are critical to the operation of a process plant. Selecting a manufacturer with well proven state-of-the-art low friction dry gas seals who can offer full field maintenance support is very important.
Gaspac® D Double Cartridge Compressor Seal

Circpac™ Circumferential Barrier Seal
Flowserve’s CircPac HP is an engineered segmented circumferential gas seal for gas compressors with higher pressure capability than typical circumferential seals. Pressure balanced ring designs and hydrodynamic surface features provide low gas consumption and long life in a variety of ring configurations.
Flowserve’s CircPac HP are able to have a variety of ring combination to be able to meet specific requirements.
Circpac MD Specialty Seal Features
- Balanced floating carbon ring design with a high pressure capability.
- Deep hydropad groove to minimize contact loads and wear.
- Narrow ring clearance that provides lower leakage than fixed clearance seals.
- Precision joint technology with a low joint bypass leakage and anti-fouling in bearing oil, solids or process contaminants.
- Simplified control system requirements compared to fixed clearance seals, control by constant pressure instead of constant flow.
- Cartridge seal assembly, compared to fixe clearance seals, control by constant pressure instead of constant flow and various barrier gases provide zero emissions without contamination.
- One piece unit reduces downtime and eliminates delicate part handling.
- Economical alternative to liquid seals and clearance seals, saves energy and no process contamination.

Carbon Ring Seal
Flowserve Circpac is a segmentedcarbon ring barrier seal. The barrier seal is used in high speed centrifugal compressors to keep the bearing oil away from the gas seal. In high speed turbomachinery the oil in the bearing cavity becomes very turbulent. By providing a barrier gas flow to the mechanical seals, the velocity of the gas exiting the carbon ring towards the oil from contaminating the compressor gas seal.
Flowserve’s CircPac can also be used as a cost-effective ‘stand alone’ carbon ring seal. It can also be configured as a multiple carbon ring to be utilized in low pressure applications where the low leakage of a conventional gas seal is not required.
The seal optimizes design life by providing a clearance between the sleeve and the carbon bushings which eliminates wear and extends the lifecycle of the equipment. The design conceptualization compliments the non-contacting GASPAC compressor gas seal providing a long time of trouble-free performance. The CircPac has often been reused after seal inspection in a variety of applications.
Features
- Protects the gas seal from bearing oil mist
- Low-heat generation -high operational safety and reliability
- Long useful-life – low-cost solution
- Shorter length than labyrinth sealless space needed at the same gas flow
- Designed to prevent process gas leakage into the bearing oil
- Close tolerance with reduced leakage over labyrinth seals
- Non-contacting design – no wear
- Bi-directional operation – reduces the stock
- Simple (uncomplicated) design – low cost solution
