Metal part: 316 Stainless Steel
MOR SRDS is a fully split, single‑spring, hydraulically balanced mechanical seal engineered for in‑situ installation-eliminating the need to disassemble pumps, mixers, or large rotating equipment for seal replacement. It is the market's fastest‑installing two‑part split seal, delivering reliable sealing performance while drastically cutting downtime and maintenance costs.
Features
Fully Split Cartridge Design: All components (rotary halves, stationary halves, gland halves) split radially for installation around the shaft without removing couplings, motors, or gearboxes.
Pre‑Assembled Spring Retainer: Springs remain uncompressed during initial assembly; compression occurs only when the gland is bolted to the stuffing box, simplifying setup.
Self‑Aligning Seal Faces: Precision‑lapped rotary and stationary faces auto‑align, ensuring consistent contact and sealing.
Hydraulically Balanced Geometry: Reduces face loading, extends seal life, and enables operation under vacuum conditions.
External Wear Indicator: Visible marker monitors seal face wear for proactive maintenance.
Minimal Parts Count: Only three O‑rings, two rotary halves, two stationary halves, two gland halves, and set screws-simplifying assembly and reducing failure points.
External Springs: Springs are isolated from process fluid, preventing clogging, corrosion, and fatigue.
Advantages
Zero Equipment Disassembly: Installs in 30–45 minutes vs. hours for standard seals, cutting downtime by 80%+.
Simplified Installation: Minimal parts and self‑aligning design reduce human error and training needs.
Long Service Life: Balanced faces and external springs minimize wear and extend MTBR.
Versatility: Fits centrifugal pumps, mixers, agitators, and large rotating equipment across industries.
Cost Efficiency: Lower labor, downtime, and replacement costs
Applications
Pulp & Paper: Stock pumps, bleach plants, and digester systems.
Oil & Gas: Refinery pumps, crude transfer, and process fluid handling.
Chemical Processing: Corrosive fluid pumps, solvent transfer, and high‑viscosity services.
Power Generation: Boiler feed pumps, cooling water systems, and auxiliary equipment.
Mining & Marine: Slurry pumps, ball mills, and marine propulsion systems.
