MU-eight and previous equipment
35 % reduction in total length achieved for 105 mm diameter with minimal metal housing
MU-eight
Features
- Cartridge unit
- Double seal with integrated bearing
- Stationary springs, balanced
Advantages
-
Compact agitator seal
- Compact cartridge design permits the use of smaller agitators than with the previous equipment (Figure 1)
- Smaller shaft diameter offers design flexibility to OEMs -
Suppressing effect on shaft runout
- Shorter distance between sliding face and bearing reduces shaft runout and stabilizes seal performance (Figure 1)
- Increased distance between bearings enhances the shaft runout suppression (Figure 2) -
Enhanced sealing performance
- Damage risk to seal faces is reduced as balanced structure minimizes load on the faces
- Secured sealing properties with stationary type of mechanical seal
- Floating sliding materials avoid the effects of flange heat deformation -
Operating cost benefits
- Common seal units mean fewer spare parts need to be kept in stock
- Flexible retrofitting: can replace existing seal unit or gland packing
