Speed  : 2900 rpm (Max)

Size  : 12 mm to 100 mm

Single Spring Balanced Seals especially designed to suit Slurry Media Sealing,light contamination, dirty media and clogging type application. This type also allows it to fit onto a normal shaft without any balancing step. The mechanical drive of this seal is realised by grub screw which lock onto the shaft.

Pressure : 30 bars (Max)

Temperature : (-)50c to (+)180c

Speed : 1500 rpm (Max)

Size : 10 mm to 100 mm

Conical Spring Seals is single conical spring, unbalanced seal with O-ring provided for secondary sealing.

Since the Torque transmission is done by the single coil springs the seals are dependent on the directions of rotation, which is seen from the drive end of the shaft.

Pressure : 10 bars (Max)

Temperature  : (-)20c to (+)180c

Speed : 10 m/sec

Size : 10 mm to 100 mm
