Double Cartridge Seals -- ZLR-1200

*Ideal for highly corrosive applications, all parts in contact with pumped fluid are made of corrosion resistant materials!

• Concentric Design – Places both rotary faces close to bearings to minimize deflection and vibration effects on seal.
• Cartridge Design – No measuring, self centering installation. Just slide over shaft, tighten gland bolts and set screws, remove centering clips, and the seal is ready to operate.
• Rotating Vanes – Ensures flush fluid circulates 360° for maximum cooling cleaning and lubrication of the seal faces. It also generates flow and pressure when a closed loop barrier fluid system is used.
• Double Balance – Allows the seal to be used as both a double seal (higher pressure barrier fluid or flush) and as a tandem seal (lower pressure barrier fluid) with the same hardware. Design also handles pressure reversals without opening.
• No Shaft Fretting - No moving parts on shaft, means no shaft damage, and no need for a sacrificial sleeve.
• Gland Insert - For High Alloy Corrosion Protection.
• Stationary Seal Design – Springs do not rotate, ensuring highest resistance against destructive vibration harmonics.
• Slotted Gland - Allows “universal” use in most rotating equipment.
