Splitex® - the fully split semi-cartridge seal

10.08.2010 + + +  Fully split, pre-assembled Splitex® mechanical seals are an ideal solution where there is insufficient space for installation or replacement of a non-split seal, if pump disassembly is very difficult, loss of production during downtime would be very expensive, or the machine operates without standby - use the Splitex®, and expensive downtime for repairs is history. 

The Splitex® is made up of 2 x 2 pre-assembled halves which are simply placed around the shaft and screwed into place without the need to disassemble the pump. The seal has the same features as a non-split cartridge seal: balanced, stationary design, precision seal pre-adjustment, and no contact between the springs and the product. No modification to the seal housing is needed, because the Splitex® is mounted fully on the outside. The seal is externally pressurized and comes with integrated flushing connections as a standard feature. 

Due to these inherent advantages, Splitex® seals are often used in water and waste water treatment, pulp and paper, marine, textile and general process applications in a wide range of pumps and agitators. 

Advantages at a glance:

- Reduced repair and downtime: 2 x 2 pre-assembled parts, which speed up and simplify installation because the 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.

- Dependable operation: Mechanical decoupling of clamping ring (torque transmission) avoids deformation or torsional stress at the seat.

- Simply 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).

- Shaft protection: Uniform torque transmission via clamping ring prevents damage caused by set screws.

Universal operating range:


Shaft diameter: d1 = 50 … 140 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 (33ft/s)
Axial movement: ± 1.5 mm (1/16")
Radial movement: ± 0.8 mm (1/32")
