Advantage Seal Type 850B Replaces:
Eagle Burgmann H74D
The type 850B type machnical seal is widely used in pumps.
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 toxic medium, medium with low solid contents and low abrasive, medium with poor lubricating performance, standard chemical pump.
Dual seal, balanced, independent of direction of rotation, step shaft
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
The design of multiple small springs makes the force more uniform, and the spring is not in contact with the medium, so it is widely used.
Can provide the widest options of materials.
