• Fully split cartridge, no pump disassembly, simply attach two halves over the shaft and mount like any other cartridge seal.
• The only split seal that can be fully pressure tested at the factory before shipping.
• Can Convert a packed pump to a sealed pump easily.
• Cartridge style setting clips allow for true axial and radial alignment without use of shims.
• It also allows for impeller adjustment without pump disassembly.
• Stationary design to enhance misalignment capabilities.
• Positive set screw drive, no clamped rubber parts as is common in other split seal designs.

• Withstands temperatures up to 800⁰F
• Static grafoil packings. Temperature sensitive O-Rings are eliminated.
• High temperature metallurgy. All parts are designed to handle elevated temperatures without any adverse effects.
• Hydraulically balanced seal. Allows seal to handle more pressure without heat build up.
• Self cleaning - Centrifugal force throws dirt away from seal.
• Stationary and drive lug options.
• cartridge design available.
• 360 degree even face loading.

• Simple installation, requires no dimensions to be taken. Slide on, bolt to box face, tighten set screws, remove spacers.
• No moving elastomers, no fretting - no hang up.
• Minimal number of parts, simple design means less pieces to cause problems.
• Fits all ANSI pump designs.
• Metric and DIN sizes readily available.
• Fits 5/16" cross section stuffing boxes.
• Easily modified to fit oversized stuffing boxes.
• Can easily convert to style 57 single spring cartridge.
• Quick and inexpensive repairs.

• Easy cartridge installation.
• Non clogging, the beefy single spring design minimizes any potential clogging in slurries, wastewater and the like.
• Repair kits, economical repair kits for in the field service.
• Converts easily to a style 50 seal with welded metal bellows.
• Shrunk in, protected faces.
• Universal gland designs, fits all ANSI pumps.

(Leaders in dual seal technology)

• Cartridge for the critical, toxic and fugitive emission applications where single seals are not acceptable.
• Easy to install cartridge designs.
• Tandem arrangement allows for maximum safety.
• Can be operated with pressurized or non pressurized barrier fluid systems.
• Pumping ring and tangential connections maximize barrier fluid flow.

• Style 78, with welded metal bellows, features static O-Rings, minimal parts and self cleaning bellows.
• Style 79 features protected stationary springs, high pressure and excessive run out capabilities.
• Can be designed to handle pressure fluctuations without face separation.

• Pre assembled at the factory. No dimensions to take. Just slide on the shaft, tighten collar, and remove setting clips.
• Hydraulically balanced seal. Factory engineered to handle internal pressure up to 150 psi.
• Readily accessible - seal faces visible. Seal is mounted outside stuffing box and can be modified without pulling the pump down.
• High strength rotating face. Carbon is shrouded in metal for extra compression strength, thus minimizing possibility of breakage.
• Adaptable to teflon or plastic sleeves. Optional split metal collar under set screws allows installation with no damage to softer materials.
