MOR S031 Split Mechanical Seal is a fully split, hydraulically balanced, single‑end mechanical seal designed for in‑situ installation on centrifugal pumps, mixers, and agitators. It eliminates the need to disassemble couplings, motors, or gearboxes during seal replacement, drastically reducing downtime and maintenance costs. This seal is widely recognized as a reliable alternative to non‑split seals in industrial process applications, and it complies with API‑682 and EN 12756 standards.
Features
Fully Radially Split Design: All components (rotary halves, stationary halves, gland halves) split radially, allowing installation around the shaft without removing drive components.
Hydraulically Balanced Geometry: Reduces face loading, enabling stable operation at higher pressures and extending seal face life.
Modular Cartridge Construction: Pre‑assembled modular design simplifies alignment and installation, minimizing human error.
External Spring Arrangement: Springs are isolated from process fluid, preventing clogging, corrosion, and fatigue in abrasive or dirty media.
Self‑Aligning Seal Faces: Precision‑lapped rotary and stationary faces auto‑align during installation, ensuring consistent sealing performance.
Shaft Protection Sleeve: Optional sleeve prevents shaft wear and fretting, extending pump shaft service life.
Wide Elastomer Compatibility: Supports NBR, EPDM, FKM and FFKM secondary seals to suit diverse fluid and temperature conditions.
Advantages
Minimal Downtime: Installs in 30–60 minutes without equipment disassembly, reducing maintenance time by up to 80% compared to non‑split seals.
Versatile Application: Suitable for centrifugal pumps, mixers, agitators, and large rotating equipment across multiple industries.
Long Service Life: Balanced face design and external springs minimize wear, extending mean time between repairs (MTBR).
Shaft Protection: Optional sleeve eliminates shaft scoring and corrosion, preserving pump integrity.
Cost Efficiency: Reduces labor costs, equipment downtime, and replacement part inventory compared to traditional component seals.
Applications
Pulp & Paper: Stock pumps, bleach plants, and digester systems handling abrasive or high‑temperature fluids.
Chemical Processing: Corrosive fluid transfer, solvent pumps, and high‑viscosity process services.
Oil & Gas: Refinery pumps, crude oil transfer, and hydrocarbon processing equipment.
Power Generation: Cooling water pumps, boiler feed pumps, and auxiliary process systems.
Mining & Minerals: Slurry pumps, ball mills, and dewatering equipment handling abrasive solids.
