The Model 585
Single Stationary Cartridge Mounted Seal

Advanced Sealing International Products PageASI has engineered the Model 585 for superior seal performance and extended seal life. Only ASI offers three style options in our universal single seal, each designed with advanced features that not only perform well, but also perform "smart", ensuring the highest quality at the lowest price today... and tomorrow.

Stationary Design- The Model 585 derives sealing face alignment from the pump shaft, not the stuffing box face, creating perfect sealing face squareness automatically upon installation.

Drive Mechanism- ASI's patented Safe-T-StudsTM transmit drive torque from the shaft to the seal from the inside of the seal, preventing seal damage, misalignment and accidental loosening common with other torque systems.

Reduced Spring Tension- During service, the Model 585's piston device forces springs into their drilled recesses eliminating spring fatigue, vapor deposits and uneven face wear. This feature reduces spring tension at low pressures and eliminates spring load completely at stuffing box pressures greater than 50 p.s.i.

Assembly Devices- ASI's unique assembly devices automatically center the lock collar and sleeve while "setting" the seal within precise specifications. The Handy-CamsTM also protect against damage in handling and upon installation, all with the ease of one-step disengagement.


The Model 724
Single Stationary Cartridge Mounted Seal

Advanced Sealing International Products PageThe ASI Model 724 offers both enhanced corrosion resistance and superior seal performance. The unique "split-housing" gland plate design provides the strength and stability of metal parts where beneficial, while protecting the process liquid from metal contaminants. Advanced seal features like monolithic seal faces, isolated springs, and ASI’s patented Safe-T-StudsTM assure continuous, reliable service and optimal seal repairability.

Non-Metallic Seal Trim- Fabricated from a high performance PPS composite material, the wetted seal components provide greater chemical resistance in a wide range of applications without any trace chemical contamination.

Metallic Seal Chassis- Removed from the product, the rigid metal gland plate and locking collar eliminate any flexing of seal parts.

Monolithic Seal Faces- One piece construction allows seal faces to compensate for temperature fluctuations without the intermittent leakage caused by face distortion.

Optimum Seal Face Alignment- The stationary design of the Model 724 in conjunction with the seal’s self-adjusting cushioned rotary face guarantees perfectly aligned seal faces.

Interchangeable Component Design- Wetted seal parts are easily removed and replaced, simplifying repairs and/or material upgrades in a "user-friendly" fashion.


The Model 600
Dual Stationary Cartridge Mounted Seal

Advanced Sealing International Products PageThe ASI Model 600 is specially engineered to withstand greater radial and axial movement common to larger equipment such as slurry pumps, mixers and agitators. The seal components are designed to work in unison, preventing under- or over-compression of the seal faces, as well as increasing free movement of the seal.

Unison Component Design- One set of springs, independent of the seal gland plate, energizes both stationary faces. Anti-rotation devices are positioned to give seal components maximum movement. This allows the seal to move freely with the pump shaft without increasing or decreasing the mechanical seal load on the inboard or outboard seal faces.

Greater Radial Clearances- The Model 600's design incorporates greater radial clearances between individual seal components, enabling the seal to compensate for increased shaft whip or radial thrust.


The Model 595
Dual Pumping Cartridge Mounted Seal

Advanced Sealing International Products PageThe ASI Model 595 offers a patented self-circulation heat removal system; the first seal pumping system that actually removes heat from the sealing faces while providing maximum movement of liquid within a compact design.

Pumping Device- The self-circulation device extends the full distance between the inboard and outboard seal faces, removing heat at its source and venting it into the flush outlet. This insures lubrication and cooling to both sets of sealing faces while the seal is circulating fluid.

Application Versatility- The Model 595's pumping feature is engineered into a convenient, cartridge mounted seal which fits all standard ANSI pumps. This patented design also enables the Model 595 to successfully perform in vertical applications and provides ideal usage in gas pressurized barrier fluid systems.

Increased Seal Life- All of the Model 595's o-rings and secondary sealing surfaces are virtually static under normal service conditions and are not required to adjust for misalignment. The rotary seal face o-rings (typically the "weakest link" in most pumping designs) are protected, guaranteeing optimum seal life and superior seal performance.

Reciprocal Design- The Model 595 can be used as a tandem seal, a double seal or a single seal with a spare seal backup. The mechanism controlling closing force to the inboard seal face is completely automatic and regulated by the differential of pressure between the process and barrier fluid.

Metal Encased Seal Faces- Both inboard and outboard seal faces are encased, protecting both plant personnel and the environment from seal face failure.


The Model 590
Dual Stationary Cartridge Mounted Seal

Advanced Sealing International Products PageThe ASI Model 590 is designed to operate with the occasional fluctuations that may occur in a seal barrier fluid supply. The features found in the Model 590 make it ideal for handling the more difficult to seal process liquids (including those that are sensitive to contact with air or may have environmental consequences).

Reciprocal Design- The Model 590 can be used as a tandem seal, a double seal or a single seal with a spare seal backup. The mechanism controlling closing force to the inboard seal face is completely automatic and regulated by the differential of pressure between the process and barrier fluid.

Cartridge Mounted- Factory assembled and pressure tested, the Model 590's cartridge unit simplifies installation and allows impeller clearance adjustments to be made without disassembling the pump.

Metal Encased Seal Faces- Both inboard and outboard seal faces are encased, protecting both plant personnel and the environment from seal face failure.

Stationary Design- The Model 590 derives sealing face alignment from the pump shaft, not the stuffing box face, creating perfect sealing face squareness automatically upon installation.

Drive Mechanism- ASI's patented Safe-T-StudsTM transmit drive torque from the shaft to the seal from the inside of the seal, preventing seal damage, misalignment and accidental loosening common with other torque systems.


The Model 510
Dual Rotary Cartridge Mounted Seal

Advanced Sealing International Products PageDeveloped to address the inherent problems associated with hot polymer, pre-polymer, monomer and plastics applications, the Model 510 is the only canister-type double seal engineered with reciprocally balanced seal faces.

Low Expansion Metallurgy- The Model 510's seal components are designed with the maximum possible cross-sections and constructed with low expansion metallurgy preventing the seal face distortion normally caused by pressure spikes and high temperatures.

Reciprocal Balance- The reciprocal balance of the Model 510 compensates for the varying pressures between normal service (vacuum) and spikes that often occur. This ensures the optimum seal face closure and prevents barrier fluid contamination, providing uninterrupted seal service during the spike, and after normal service resumes.


The Model 730
Single Stationary Cartridge Mounted Seal

Advanced Sealing International Products PageThe ASI Model 730 provides a superior quality, low cost alternative to "throw-away" seals. The Model 730's self-contained cartridge unit and detachable seal flange allow a wide range of stocking and repair options. The reduced operating length of the Model 730 creates stronger seal parts (capable of running at higher pressures), and its stationary design delivers the performance reliability the ASI name has come to represent.

Unitized Cartridge Seal Barrel- The convenient one-piece assembly easily detaches from the seal flange, allowing "mix and match" stocking options and simplified replacement.

Monolithic Seal Faces- One piece construction allows seal faces to compensate for temperature fluctuations without the intermittent leakage caused by face distortion.

Uni-body Sleeve Construction- The advanced machining techniques utilized to create the one-piece sleeve provide optimum concentricity and perpendicularity for absolute squareness to the pump shaft.

Interchangeable Flange Option- The removable seal flange can be reused (reducing repair or replacement costs), and easily swapped out to accommodate special bolting patterns.

Optimum Seal Face Alignment- The combined features of the Model 730, including its stationary design, self-adjusting rotary face and uni-body sleeve construction, guarantee perfectly aligned seal faces, and ultimately, improved seal performance and increased seal life.
