MOR CSSN is a single‑end, multi‑spring, hydraulically balanced cartridge mechanical seal engineered for reliable performance in general industrial and process pump applications. Developed as a high‑value, robust sealing solution, it is widely recognized as a direct replacement for standard cartridge seals and fits most ANSI/DIN centrifugal pumps, slurry pumps, and process equipment. Its pre‑assembled cartridge design eliminates installation errors and delivers consistent sealing for clean, slightly abrasive, and corrosive fluids.
Features
Fully Pre‑Assembled Cartridge Unit: Factory‑set compression and alignment ensure fast, error‑free installation without complex adjustments.
Multi‑Spring System: Alloy 276 helical coil springs provide uniform face loading; springs are isolated from process media to prevent clogging, corrosion, and fatigue.
Hydraulically Balanced Face Design: Reduces heat generation, stabilizes fluid film, and extends service life under pressure fluctuations.
Captured Rotary O‑Ring: Prevents O‑ring extrusion under vacuum or high‑pressure conditions.
Direct Drive Mechanism: Drive screws clamp securely to the shaft/sleeve for reliable torque transmission with minimal power loss.
Modular Face & Elastomer Options: Wide material compatibility for diverse fluid and temperature conditions.
Shaft Protection: Integrated sleeve safeguards the pump shaft from wear and scoring.
Standard Flush/Vent Ports: Compatible with API sealing plans (Plan 11, 21, 32) for cooling and flushing.
Bi‑Directional Rotation: Operates efficiently regardless of shaft turning direction.
Advantages
Easy installation & maintenance: Cartridge design cuts downtime; no need for coupling/motor disassembly.
Superior reliability: Balanced design and isolated springs ensure stable operation in demanding services.
Versatility: Compatible with most centrifugal, slurry, and process pumps; ideal for retrofits.
Cost‑effective: Long service life, low wear, and minimal maintenance reduce total ownership cost.
Vacuum & pressure resistance: Captured O‑ring and balanced design perform reliably across pressure ranges.
ATEX compliance: Safe for use in hazardous Zone
Applications
Centrifugal pumps (water, oil, chemicals)
Slurry pumps (pulp & paper, mining, FGD)
Chemical and petrochemical process pumps
