EagleBurgmann Splitex Split Seals
Splitex
Replaced for EagleBurgmann Splitex;
Chesterton 221 Split seals
Features
•Fully split single seal, 2 x 2 segments, pre-assembled
•Semi-cartridge
•Balanced
•Stationary springs
•Bi-directional
•External pressurization
•Built-in flushing connections
•Installation and wear control
Advantages
•Reduced repair and downtime: 2 x 2 pre-assembled design speeds up and simplifies installation because pump does not have to be disassembled.
•Long service life: precise pre-alignment because of pre-assembled segments. Stationary springs which are protected from the product prevent clogging.
•Greater flexibility during installation: no modification necessary because the seal is located outside of the stuffing box.
•Shaft protection: uniform torque transmission via clamping ring prevents damage caused by set screws.
•Dependable operation: mechanical decoupling of clamping ring (torque transmission) avoids distortion of the seat.
•Simple monitoring of the seal during operation because of mechanical wear indicator on the seal face.
•Low leakage: elimination of secondary seals eliminates leakage paths between split components.
•High tolerance to shaft deflections ensured by stationary design and elastic seat mounting (gasket).
