Alfa Laval LKH Double Mechanical Seals: High-Performance Flushed Shaft Sealing
Upgrade your heavy-duty fluid transfer lines with premium, OEM-standard replacement Alfa Laval LKH Double Mechanical Seals. Engineered specifically for the world's most trusted centrifugal pump line, these dual shaft seals deliver a rugged, zero-leak barrier for demanding processing environments.
Our flushed seal kits offer 100% drop-in compatibility across the entire LKH family—including standard LKH-10, LKH-20, LKH-35, LKH-50, LKH-70, high-pressure LKH Multistage, and high-purity LKH UltraPuremodels.
How the LKH Double Flushed Design Works
Unlike standard single seals that rely purely on the pumped product for face lubrication, the LKH Double Mechanical Seal arrangement introduces an isolated atmospheric barrier chamber between a primary product seal and a secondary flush seal.
- Continuous Barrier Flush: By circulating a continuous external flush medium (such as low-pressure water or steam), the system instantly absorbs facial friction heat and prevents raw product solidification.
- Atmospheric Isolation: It creates a positive physical barrier that locks hazardous, sticky, or sensitive media safely inside the pump casing, keeping your staff and processing floor completely contamination-free.
- Dry-Running Protection: If your production line experiences a brief "dry run" or fluid interruption, the active external flush continues to cool the faces, preventing catastrophic seal shattering or face cracking.
Best For: Severe-Duty Industrial and Sanitary Applications
The LKH double flush setup is the premier industry solution when your pumped product is too aggressive for a single mechanical seal face to survive:
- Crystallizing Sugars & Concentrates: Best for liquid sugar, high-fructose corn syrups, molasses, and glazes where ambient exposure would cause crystals to form and shred standard single seal faces.
- Abrasive Slurries & High-Solids: Ideal for handling heavily filled dairy concentrates, viscous sauces, fruit purées with seeds, brewing yeast slurries, and chemical particulates.
- High-Temperature Processing & Aseptic Lines: The active flush acts as an immediate coolant and barrier, preventing thermal cracking on the seal faces when running hot CIP sterilization chemicals or maintaining strict sterile isolation.
