Advantage Seal Type 846 Replaces:
Eagle Burgmann® M7N,
AESSEAL® W07DMU,
VULCAN® 1677
The 846 type machnical seal is widely used in pumps.It’s not sensitive to low solids contents.
The transmission mode can be changed to provide maximum durability and performance. it’s very suitable for standard chemical pumps, vertical screw pumps, gear pumps and other optional equipment.
Commonly used in chemical industry applications, such as lubricating oil, medium with low solids content and other general applications.
Single seal, unbalanced, independent of direction of rotation
Design standard: IS03069,DIN24960
The push ring is stuck by the transmission coupler to prevent the spring from falling off, and the sealing ring is not tightly embedded, which is convenient to replace
Wave-shaped spring structure allows conveying materials with particles, crystals and high viscosity, and is widely used.
Can provide the widest options of materials.
Pressure：p1 = 20 bar (290 PSI)
Temperature：t = -40 °C(-40°F) … +200 °C (+392°F)
Sliding velocity：vg = 20 m/s (66 ft/s)
Water, oil, acid, alkali, organic solvent, etc., allow a small amount of particles, crystallization, high viscosity medium.
