NOTICE:
The mechanical seal must have an appropriate seal-flush system. Otherwise, excess heat generation and
seal failure can occur.
1. Assemble the seal chamber:
a) Install a seal-chamber cover and fasten with hexagon head screws.
b) Install the shaft sleeve (524).

2. Mark the shaft and sleeve at the face of the seal chamber.
3. Continue the complete reassembly of the pump, except for the mechanical seal.
4. Scribe a line on the marked shaft and sleeve at the face of the seal chamber.
5. Remove the casing, the impeller, and the seal chamber.
6. If applicable, slide the gland, with the stationary seat and gland gasket installed, onto the shaft until it
contacts the inboard labyrinth oil seal.
7. Install the mechanical-seal rotary unit according to the manufacturer's instructions.
Use the scribed line and the seal-reference dimension.
8. Reinstall the seal chamber.
9. Slide the gland on the seal-chamber studs and secure them with the gland nuts.
Tighten the nuts evenly so that the gland is seated on the seal-chamber pilot and is perpendicular to
the shaft.
10. Complete the reassembly of the pump.
Install the impeller
CAUTION:
Wear heavy work gloves when you handle impellers. The sharp edges can cause physical injury.
For the fitting threads and for tight tolerances, use a suitable anti-seize compound. Use this, for example,
between the shaft sleeve and the shaft or between the impeller and the shaft. This makes the assembly and
the next disassembly easier to perform.
NOTICE:
Anti-seize compounds must be compatible with the pumped fluid.
Perform these steps in order to install the impeller:
