MOR 155 Single Cartridge Mechanical Seal is a pre‑assembled, single‑spring, hydraulically balanced mechanical seal purpose‑built for circulating pumps (including centrifugal, water, and process circulation pumps). It is a standard industrial cartridge seal offering easy installation, reliable performance, and cost‑effective sealing for clean water, cooling water, and general process fluids.
Features
Fully Pre‑Assembled Cartridge Unit: Integrates shaft sleeve, gland, seal faces, springs, and secondary seals into one unit-no on‑site component assembly required.
Single Spring Design: Robust single spring provides consistent face loading and self‑compensation for wear.
Hydraulically Balanced Geometry: Reduces face pressure, lowers heat generation, and extends service life.
Monolithic Seal Faces: Precision‑lapped, low‑friction faces minimize heat buildup, ideal for non‑lubricating fluids.
Dual Flush/Monitoring Ports: 360° rotatable ports for flush connection, cooling, or condition monitoring.
Adjustable Gland Tabs: Accommodates various stuffing box bolting patterns for universal fit.
Shaft Protection Sleeve: Prevents shaft wear, fretting, and corrosion.
Wide Material Compatibility: Supports multiple face, elastomer, and metal options for diverse fluids.
Advantages
Fast, Error‑Free Installation: Slides onto the shaft and bolts directly to the stuffing box; no alignment or component fitting needed, cutting installation time by 70%+.
Low Maintenance: Self‑compensating springs and robust design reduce downtime and service frequency.
High Reliability: Balanced faces and durable materials ensure consistent sealing in circulation service.
Versatility: Fits most standard circulating pumps across water treatment, HVAC, power, and general industry.
Applications
Water Circulation: Cooling water pumps, chilled water systems, HVAC circulation pumps.
Industrial Process: Clean water, condensate, and low‑corrosive fluid circulation.
Municipal & Utilities: Water treatment plants, booster pumps, and general service pumps.
HVAC & Building Services: Commercial and industrial heating/cooling circulation systems.
General Industry: Chemical, pulp & paper, food & beverage, and power generation circulation services.
