All SENTINEL® Filter Bags utilize the patented SENTINEL® seal. It's all plastic, polypropylene, polyester or Santoprene® construction, provides a flexible, chemically resistant seal which adapts to any filter housing. This unique design employs a pressure activated sealing lip which responds to increases in differential pressure. As the pressure increases, the seal of the ring improves, insuring by-pass free performance over all ranges of pressure, temperature and micron rating. The elevated bag handles make removal of the bag from the vessel quick and easy. When a SENTINEL® Filter Bag is installed into an Eaton Filtration Housing, the ring snaps into place, holding its position until the housing is closed.

An element forms a sealing function when it prevents the passage of a fluid from a one enclosure to another. Such elements are called "Seals".
If the object is to prevent the flow of a fluid from an enclosure into a neighbouring enclosure, the seal is called a Single Seal. If the seal must prevent the flow of another fluid which may be in the second enclosure into the first, the seal is called a double seal.
If the two mechanical parts between which the leakage is likely to occur are fixed with relation to each other, the seal is called static seal. If one or both of these parts is moving relative to the other, the seal is called a dynamic seal.

Bal Seal Engineering canted-coil springs produce a nearly constant force over the working spring deflection unlike other types of springs where the spring force is directly proportional to deflection. Our products are available in continuous lengths or circular spring form with outside diameters from 0.020" (0.51mm) and wire sizes as small as 0.0025" (0.64mm). Spring forces are determined by material, coil size, and geometry. Bal Seal Springs are be custom engineered to meet your application requirements.
Bal Seal can accommodate high volume production requirements while meeting today's exacting quality standards.

The MSE® seal consists of a PTFE or other polymer energized by a corrosion-resistant metal spring. When the seal is seated in the gland, the spring is under compression and applying force on the gland-sealing surfaces. This creates a tight barrier to prevent gas or fluids from leaking. The spring also provides resiliency to compensate for seal wear, gland misalignment or eccentricity. While spring force provides adequate force for sealing at low pressure, at high pressure the system pressure augments the spring force to provide an even tighter seal. MSE seals are precision machined from PTFE, filled PTFE and other high-performance polymers. MSE seals work consistently under a wide array of temperatures and pressures. Greene, Tweed offers over 100 jacket materials, four standard spring materials, and four standard spring designs to meet your sealing needs.

Greene, Tweed's unsurpassed expertise in elastomeric and thermoplastic compounding has resulted in the design of this exceptionally long-life, low-friction seal. The Bandseal (GTB) is a self-actuating extrusion resistant seal combining low breakout and running friction with minimal leakage over extended service life. The seal is constructed of premium grade PTFE sealing caps and elastomer energizers. Greene, Tweed's GTB Bandseal is a compact single-acting seal for sealing reciprocating rods but is also available as a single-acting cylinder bore seal. The Bandseal has no stickslip effect. Its fluid feedback capability means the Bandseal cannot cause a pressure trap when assembled in tandem arrangements. The GTS Bandseal operates in temperatures ranging from -85°F (-65°C) to 500°F (260°C) with pressure up to 200 bar standard (higher pressures are possible).

The Labyrinth Seal is an effective barrier against water and other contaminants that destroy bearings. Non-contacting rotary and stationary elements provide a restricted flow path and utilize centrifugal force and gravity to prevent intrusion of contaminants into the bearing chamber. Unlike common lip seals, the Labyrinth Seal will not damage shafts and has a virtually unlimited life.

Mechanical seals are used for the sealing of rotating shafts against a stationary housing, e.g. in pumps and agitators. The stationary" part of the seal is usually located at the housing, the rotating" part is fixed on the shaft. The high-precision face-machined sliding faces rotate axially in opposition. The sliding faces are pressed against each other by means of spring force, thus preventing the opening of the seal. The seal faces are statically sealed against the housing and the shaft by secondary seals (O-rings). With the entry of the pumped medium into the minimal sealing gap a lubricating film is generated and the sealing effect is thus obtained.
The design, arrangement and combination of materials of the seal is basically determined by pressure, temperature, speed of rotation and quality of the pumped medium. Shaft diameters of 5...500 mm, pressures from 10 torr ....250 bar, temperatures from -200°C... +450°C and sliding velocities up to 150 m/s limit the operating range of mechanical seals. Additional seal supply systems or buffer fluid systems may be required, dependent on the mode of operation, the quality of the medium and the seal arrangement.

PTFE gaskets are one of the most suitable types of gaskets for a variety of sealing applications and are mostly based on virgin PTFE, PTFE compounds, filled PTFE or expanded PTFE. And what provides the PTFE gaskets with such an extensive range of applicability? The answer is PTFE. PTFE is a fluoropolymere, which features an outstanding chemical resistivity to almost all chemicals, good thermal insulation properties, and useful mechanical and processing characteristics. The above-mentioned PTFE features can be usefully applied in PTFE gaskets. They can be mostly used in valve seats, bearings, requested to resin sliding and chemicals, elastic bands for an-lubricated compressors, O-rings where elastomers can not withstand.
An extended range of improved mechanical and processing properties can be additionally reached by a combination of virgin PTFE and different fillers.
Expanded PTFE Gaskets and Seal materials consist of virgin PTFE with multidirectional fibrous and/or porous structure, which the extruded PTFE consists of. A special manufacturing process provides the material with special chemical and physical properties. This can be of advantage in wide range of the applications.
Advantages
Virgin PTFE, PTFE compounds and expanded PTFE offer a wide range of compounded products with good mechanical properties, electrical properties, thermal properties, chemical resistance, low friction coefficient and good resistance to wear.
Shape and construction
Several types pf DONIT TESNIT® - PTFE gaskets are produced to meet the most demanding applications.
