MOR 522 Mixer Seal is a single‑acting, balanced mechanical seal developed by EKATO (Germany), primarily designed for agitators/mixers and centrifugal pumps in process industries. It features a robust, compact structure with a single sealing interface, optimized for low‑to‑medium pressure, clean to mildly corrosive fluids, and reliable operation under product‑lubricated or dry‑running conditions
Key Features
Single‑Acting, Single‑Seal‑Face Design: Two precision‑mated seal rings (rotating + stationary) with one sealing interface; no separate seal liquid chamber
Balanced Seal Geometry: Hydraulically balanced to reduce face loading, enabling higher pressure capability and extended service life.
Product‑Lubricated / Dry‑Running: Operates with process fluid for lubrication/cooling, or in dry service (low‑pressure, non‑critical media)
Robust Spring Drive: Reliable spring‑loaded pre‑tension for consistent face contact; compensates for shaft runout, vibration, and wear.
Cartridge‑Style (Optional): Pre‑assembled cartridge unit for fast, error‑free installation; no shaft adjustment required.
Visual Wear Indicator: Optional feature for easy monitoring of seal face wear status
Wide Shaft Compatibility: Fits standard agitator/pump shafts; customizable for special sizes.
Applications
Chemical & Petrochemical: Agitators for solvents, surfactants, polymers, and mild acids/alkalis.
Pharmaceutical & Food: Mixers for clean, sterile, and high‑purity process fluids.
Pulp & Paper: Black/white liquor, pulp slurries, and process water agitators.
Water & Wastewater: Treatment tanks, sludge mixers, and neutralization reactors.
General Industry: Low‑pressure mixers, reactors, and centrifugal pumps with clean/non‑critical fluids.
Advantages
Simple & Cost‑Effective: Single‑face design reduces complexity and maintenance costs
Easy Installation: Plug‑and‑play; no spring pre‑tension adjustment post‑installation
Versatile Operation: Works with product lubrication or dry‑running (low‑pressure)
Low Emissions: Minimal leakage to atmosphere for non‑hazardous media
Long Service Life: Balanced design and robust materials resist wear and corrosion
