MOR SE2-AP is a heavy-duty, double cartridge mechanical seal designed specifically for demanding centrifugal pump applications in process industries. Built as a robust, fully pre-assembled cartridge unit, it provides reliable dual sealing performance for abrasive, corrosive, high-temperature, and hazardous fluids. This seal combines strong axial flexibility, stable face loading, and easy installation, making it widely used in chemical, petrochemical, pulp & paper, water treatment, and power generation sectors.
Features
Double Cartridge Construction: Fully pre-assembled and preset at the factory to ensure correct compression, eliminating installation errors and reducing assembly time.
Dual Seal Arrangement: Dual seal faces provide enhanced safety and leakage control, suitable for fluids requiring zero emission or secondary containment.
Balanced Seal Faces: Hydraulically balanced design reduces heat generation and extends service life under pressure and thermal cycling.
Stationary Spring System: Springs are isolated from process media to prevent clogging, corrosion, and fatigue in dirty or abrasive services.
Self-Aligning Faces: Maintains consistent contact even under shaft runout and misalignment.
Shaft Protection Sleeve: Protects the pump shaft from wear, scoring, and corrosion.
Multiple Flush & Vent Ports: Compatible with API sealing plans for flushing, cooling, and barrier fluid systems.
Wide Material Compatibility: Offers various face, elastomer, and metal options to suit different fluid conditions.
Advantages
Zero leakage performance: Dual seal design ensures high reliability for hazardous and toxic fluids.
Cartridge-type installation: Fast, simple, and alignment-free mounting without disassembly of couplings or motors.
High resistance to abrasion and corrosion: Suitable for solids-containing and aggressive process fluids.
Low maintenance and long service life: Stable operation reduces downtime and replacement costs.
Excellent tolerance to shaft misalignment and vibration.
Universal fit for most ANSI, DIN, and standard process centrifugal pumps.
Applications
Chemical and petrochemical process pumps
Refinery hot oil and hydrocarbon pumps
Pulp & paper stock and bleach plant pumps
Flue gas desulfurization (FGD) pumps
Wastewater and sewage treatment pumps
High-temperature hot water and thermal fluid pumps
