Disassembly
1.
Remove Screw (pos. 17). Loosen with Key (tool No. TE134) and unscrew with Screwdriver (tool
No. TE134A).
2.
Lift off Nipple (pos. 1).
3.
Remove Guide/Guide ring (pos. 2). The Guide has a groove in the outer diameter. The Guide is
easily lifted out of the Stem by means of two ordinary Screwdrivers inserted into the groove.
4.
Remove Screw (pos. 17), Spring washer (pos. 18) and Washer (pos. 14). To secure Impeller
against rotation, insert carefully Screwdriver (tool No. TE134A), through Impeller (pos. 4) into a
hole in the Stem.

Reassembly
1.
Carefully put on the stationary seat of Mechanical seal (including O-ring) into the house. When
inserting the stationary seats, be careful to apply even pressure and use only water or alcohol to
reduce O-ring friction.
Note:
: Absolute cleanliness and care is essential when fitting mechanical seals. Dirt and
damage to sliding faces and O-rings jeopardise the function of a seal. Never put lubricant on the
sliding faces – mount only in a completely dry, dust free and clean state.
2.
Reinstall Impeller (pos. 4). Make sure that Impeller is correctly rotated to be pushed onto Turbine
shaft. Do not try to hammer Impeller in position, as this will damage Ball bearing under the Turbine
shaft.
3.
Mount Washer (pos. 14), Spring washer (pos. 18) and Screw (pos. 17) and tighten. To secure
Impeller against rotation insert carefully Screwdriver (tool No. TE134A) through Impeller (pos. 4)
into a hole in the Stem.
4.
Reinstall Guide/Guide ring (pos. 2).
5.
Mount Nipple (pos. 1). Make sure that it is in correct position over Guide/Guide ring (pos. 2).
Rotate Nipple to align holes in Nipple and Stem.
6.
Mount Screws (pos. 17) with Screwdriver (tool No. TE134A). Tighten with Key (tool No. TE134).
