Elastomer Bellows
Elastomer bellows mechanical seals are commonly used in a wide range of industries, including oil and gas, chemical processing, water treatment, and power generation, due to elastomer's ability to seal effectively in a variety of applications.
Seal Types
RB10 (E1)
Known for exceptional performance this full convolution elastomer bellows seal is an industry workhorse.
FEATURES
- Design eliminates slippage, which protects the shaft and sleeve from wear
- Automatic adjustment to compensate for wear and other concerns like abnormal shaft play and run-out
- Designed with special balancing for reducing wear at higher pressure and speeds
- Typically used in process pumps and other rotating equipment
PARAMETERS
Pressure: 425 psi
Temperature: -40°F to 400°F/-40°C to 205°C (depending on materials used)
RB1A (E2)
RB1A seals are available in single, double or balanced configurations to suit your specific needs.FEATURES
- Designed with a drive band and notches that prevent excessive stress of the bellows
- Eliminates slippage
- Non-clogging design increases dependability
- Typically used in process pumps and other rotating equipment
PARAMETERS
- Pressure: 420 psi
- Temperature: -40°F to 400°F/-40°C to 205°C (depending on materials used)
- Speed: Varies
RB1C (E21)
The RB1C mechanical seal is the industry standard for OEM designers, particularly when durability and equipment tolerances are a concern.
FEATURES
- Drive band design prevents overstressing the elastomer bellows
- Single-coil spring and non-clogging design is more dependable than multiple-spring counterparts
- Typical uses include process pumps and other rotating equipment
PARAMETERS
Pressure: 150 psi
Temperature: -40°F to 400°F/-40°C to 205°C (depending on materials used)
Speed: Up to 2500fpm/13m/s, depending on configuration and shaft size
RB1D (E2100)
This completely unitized, heavy duty seal is made for demanding applications where durability and performance are key concerns.FEATURES
- Unitized for easy installation and replacement.
- Pressure-supported design will not fold or crease under high pressure.
- Single-coil, non-clogging spring design keeps seal faces tracking properly
- Interlocking tangs alleviate slippage or breaking free
- Typically used in process pumps and other rotating equipment
- Face load 50-75% less than spring seal
- Short axial length
- Reduced friction on seal face lowers heat and wear resulting in longer seal lifespan
PARAMETERS
- Pressure: 290 psi
- Temperature: -40°F to 400°F/-40°C to 205°C (depending on materials used)
- Speed: 3000fpm
RB1B (E6)
This unitized seal head is ideal for small-diameter pumps where compact size is a must.FEATURES
- Unitized design means easy replacement and efficient production line installation
- Elastomer drive ring provides positive sealing and drive without using drive pins or set screws
- Ferrules and coil spring keep face loading consistent, even in extreme conditions
- Typically used in process pumps and other rotating equipment
PARAMETERS
Pressure: 7.20 psi ID; 75 psi OD
Temperature: -40°F to 400°F/-40°C to 205°C (depending on materials used)
Speed: 1000fpm/5m/s
Up to 3600 rpm, depending on configuration and shaft size
SB10 (E6A)
These compact, single-spring seals are an ideal solution for small centrifugal water pumps, and other submersible pumps.
FEATURES
- Broad range of applications
- Design allows full convolution bellows for maximum flexibility to deal with shaft movement and wear.
- Spring oil for consistent face loading, even in harsh or extreme conditions.
- Torsional stress is limited by dent and groove positive drive configuration.
- Can tolerate higher operating speeds than similar rotating seal head configurations due to rotating mating ring.
PARAMETERS
Pressure: 7.20 psi ID; 75 psi OD
Temperature: -40˚C to +205˚C/-40˚F to +400˚F (depending on materials used)
Speed: Up to. 2500 fpm; Up to 10,000 rpm (depending on seal size and face materials)
