SS-Splitex: Burgmann Splitex split mechanical seal
Structure Description
Equivalent to Burgmann Splitex seal
Fully split single seal, 2 x 2 segments, preassembled
Semi-cartridge
Balanced
Stationary springs
Bi-directional
External pressurization
Built-in flushing connections
Operating range
Shaft diameter: d1 = 50 … 150 mm (1.940" … 6.000")
Pressure: p1 = 10 bar (145 PSI)
Temperature: t = -40 ... +150 °C (- 40 … + 300 °F), above 80 °C (175 °F) flush is recommended
Sliding velocity: vg = 10 m/s (33 ft/s)
Axial movement: ± 1.5 mm (1/16")
Radial movement: ± 0.8 mm (1/32")
Materials
Seal face: Carbon graphite antimoniny impregnated (A), Silicon carbide (Q6)
Seat: Silicon carbide (Q6)
Secondary seals: FKM (V), EPDM (E), NBR(P)
Springs: CrNiMo steel (G)
Metal parts: CrNiMo steel (G)
Advantages
*Reduced repair and downtime: 2 x 2 preassembled design speeds up and simplifies installation 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).
