Comparison based onpumps of similar flowand head operating365 days a year, 24 hours per day.

Sealless pumps require approximately25% more horsepower to achieve thesame flow and head as a conventionalpump sealed with a GX-200.

Easier to install and maintain than closed-loop liquid barrier sealsIUnlike complicated liquid barrier supply systems, the clean gas supply system required for the GX-200 is simple to install andmaintain. Just tap into a gas supply header and install a pressure regulator, filter, flow meter, and pressure gauge. Because thegas is dead-ended in the seal, no purge or continuous flow through is needed.

GX-200Gas Barrier Seal for standard bore seal chambers

The GX-200, a superior design utilizing non-contactinin a wide variety of applications

The GX-200 seal not only offers our exclusive non-contactingseal face technology for extended equipment life, but increasedenergy savings and reliability.

The new GX-200 is more than a gas barrier seal thatoffers zero emissions, increased energy savings, andincreased reliability, it is specifically engineered to fitstandard or small bore seal chambers without requi-ring pump modifications.

Best of all, the GX-200 combines these engineering advances:

• proven Advanced Pattern Groove System (APGS) face geometry for non-contacting seal face operation

• a reliable metal bellows design for long life operation

• the installation simplicity of a cartridge design.

Unique face pattern is the key to zero emissions and long life

• Exclusive patented* face pattern contains special shallow grooves to provide both hydrostatic and hydrodynamiclift of the seal faces. Results are reduced energy consumption during pump start-up and operation, and no sealface wear.

• The GX-200 is designed to provide zero product emissions performance even under off-design or dry runningconditions that can cause sealless pumps to fail.

The GX-200 is designed for applications in chemical processing, hydro-carbon processing, pulp and paper, pharmaceutical and food processingindustries. This pressurized dual seal configuration provides outstandingperformance in processing environments and helps to facilitate compli-ance with hazardous emissions regulations.

Reduces operation and maintenance costs• Eliminates the costs of maintaining a liquid barrier system and

eliminates barrier fluid contamination of the process.

• Provides cost and performance advantages over sealless pumps.
