BRC| PRESSURE: | TO 300 psi | | TEMPERATURE: | TO 800 F | | SPEED: | TO 4500 fpm | | STD SIZES: | 0.983" TO 5.937" |
|
Balanced welded rotating Alloy 718 bellows seal for high temperature petrochemical services. The rotating face uses a contained face instead of a shrinkfit, which is another way of achieving low face distortion. This design is excellent for corrosive service. The use of extra thick Alloy 718 bellows diaphragms provides a very rugged bellows core. Since the bellows is rotating it provides a so-called 'self-cleaning' effect which reduces the possibility of solids entering the bellows convolutions. |
BX| PRESSURE: | TO 400 psi | | TEMPERATURE: | TO 400 F | | SPEED: | TO 4500 fpm | | STD SIZES: | 7/8" TO 5" |
|
Balanced welded rotating metal bellows seal for general service, primarily applied in the petrochemical and chemical industry. The standard BX uses a 316 bellows core, but when equipped with a Alloy C-276 bellows core it complies fully with all requirements of API 682 type B. Rotating bellows provides 'self-cleaning' effect. |
BXHH| PRESSURE: | TO 300 psi | | TEMPERATURE: | TO 750 F | | SPEED: | TO 4500 fpm | | STD SIZES: | 1-3/8" TO 5" |
|
Balanced welded rotating Alloy 718 bellows seal for high temperature petrochemical services. This seal complies fully with all requirements of API 682 type C. The use of Alloy 718 material and a low stress bellows design provides improved corrosion resistance. The special stationary face shrinkfit design minimizes face distortion and allows low leakage and low wear under a wide range of conditions. The bellows is rotating so it provides a so-called 'self-cleaning' effect which reduces the possibility of solids entering the bellows convolutions. |
BXLS| PRESSURE: | TO 400 psi | | TEMPERATURE: | TO 450 F | | SPEED: | TO 4500 fpm | | STD SIZES: | 18mm TO 100mm |
|
Balanced welded rotating metal bellows seal according DIN 24960 L1k. Intended for general purpose DIN pump applications for the process industry. The BXLS is based on the standard BX and uses a 316 bellows core. The seal has high reverse pressure capability with retained stationary face. Because the bellows is rotating it provides a so-called 'self-cleaning' effect which prevents solids from entering the bellows convolutions. |
BXR| PRESSURE: | TO 400 psi | | TEMPERATURE: | TO 550 F | | SPEED: | TO 9000 fpm | | STD SIZES: | 7/8" TO 4" |
|
Balanced welded stationary metal bellows seal for general service, primarily applied in the petrochemical and chemical industry. Because of the stationary bellow the seal is less sensitive for misalignment and off-squareness, and can tolerate high speeds. |
BXRH| PRESSURE: | TO 300 psi | | TEMPERATURE: | TO 800 F | | SPEED: | TO 9000 fpm | | STD SIZES: | 1-1/4" TO 5-3/8" |
|
Balanced welded stationary Alloy 718 bellows seal for high temperature petrochemical services. This seal complies fully with all requirements of API 682 type C. The use of Alloy 718 material and a low stress bellows design provides improved corrosion resistance. The special patented stationary face shrinkfit design minimizes face distortion and allows low leakage and low wear under a wide range of conditions. Because of the stationary bellows the seal is less sensitive to misalignment and off-squareness, and can tolerate high speeds. |
CBR| PRESSURE: | TO 300 psi | | TEMPERATURE: | TO 400 F | | SPEED: | TO 4500 fpm | | STD SIZES: | 3/4" TO 5-1/2" |
|
Balanced welded stationary metal bellows seal for general service, primarily applied in the refining, petrochemical and chemical industry. Because of the stationary bellow the seal is less sensitive for misalignment and off-squareness, and can tolerate high speeds. |
PBR| PRESSURE: | TO 350 psi | | TEMPERATURE: | TO 750 F | | SPEED: | TO 4500 fpm | | STD SIZES: | 1-1/8" TO 4-1/2" |
|
Single inside bellows specifically designed for high temperature applications in the petroleum industry. Advanced face attachment permits thermal expansion without distortion of the faces. Seal faces are also easily replaced. Patented tapered insert design ensures correct installation of grafite high temperature insert mountings. |
UNISEAL I| PRESSURE: | TO 200 psi | | TEMPERATURE: | TO 400 F | | SPEED: | TO 4500 fpm | | STD SIZES: | 1-1/8" TO 2-1/2" |
|
Single metal bellows cartridge design for general purpose ANSI pumps. The Uniseal uses Alloy C-276 bellows with high level of corrosion resistance. Since the bellows is rotating it provides a so-called 'self-cleaning' effect which reduces the possibility of solids entering the bellows convolutions. |
UNISEAL I PLUS| PRESSURE: | TO 400 psi | | TEMPERATURE: | TO 400 F | | SPEED: | TO 4500 fpm | | STD SIZES: | 1-1/8" TO 2-5/8" |
|
Single metal bellows cartridge design for general purpose ANSI enlarged bore pumps. The Uniseal Plus uses the heavy duty BX Alloy C-276 bellows with high level of corrosion resistance. Since the bellows is rotating it provides a so-called 'self-cleaning' effect which reduces the possibility of solids entering the bellows convolutions. |
UNISEAL II| PRESSURE: | TO 200 psi | | TEMPERATURE: | TO 400 F | | SPEED: | TO 4500 fpm | | STD SIZES: | 1-1/8" TO 2-1/2" |
|
Tandem metal bellows cartridge design for general purpose ANSI pumps. Double balanced inboard faces, therefore can be used as pressurized dual seal. The Uniseal uses Alloy C-276 bellows with high level of corrosion resistance. Since the bellows is rotating it provides a so-called 'self-cleaning' effect which reduces the possibility of solids entering the bellows convolutions. |
X-100| PRESSURE: | TO 300 psi | | TEMPERATURE: | TO 400 F | | SPEED: | TO 4500 fpm | | STD SIZES: | 1-1/8" TO 4-1/8" |
|
Single metal bellows cartridge design for general purpose ANSI pumps eliminates shaft packing hang-up and shaft or sleeve fretting. Uses patented face attachment technology to increase seal life. Pre-set cartridge simplifies installation, eliminates guesswork. Easily converted to a double or tandem seal using interchangeable components. Since the bellows is rotating it provides a so-called 'self-cleaning' effect which reduces the possibility of solids entering the bellows convolutions. |
X-200| PRESSURE: | TO 200 psi | | TEMPERATURE: | TO 400 F | | SPEED: | TO 4500 fpm | | STD SIZES: | 1-1/8" TO 4-1/8" |
|
Double, cartridge mounted metal bellows seal ideal for use in mild abrasive services where added security of a double seal is necessary. Bellows design eliminates dynamic gasket hang-up and fretting. Patented bi-directional flow inducer aids in proper cooling, extending seal life. Can operate as a tandem configuration, so withstands pressure reversals. Since the bellows is rotating it provides a so-called 'self-cleaning' effect which reduces the possibility of solids entering the bellows convolutions. |
