Shaft Seal Replacement

The shaft seal must be replaced if:

– Pumping medium or sealing or quenching liquid flows out of

the pump on the atmosphere side.

– Sealing liquid leaks into the pumping medium.

Procedure

1. Remove the pump head (see

Chapter 9.8, " Pump Head

Removal," page 18

2. Replace the mechanical seal, and mount the pump head (see

Chapter 9.10, "Pump Head Attachment," page 20

). Perform the

following tasks according to the given shaft seal:

►

Preassemble the seals on the shaft.

►

Preassemble the pump casing.

►

Mount the pump casing on the lantern.

►

Mount the mechanical seal.

►

Mount the impeller.

►

Screw on the pump cover.

Pump Head Removal

9.8.1

Preparation

1. Turn off the motor and prevent it from being able to be

turned on accidentally.

2. Close the valve in the discharge line.

3. Close the valve in the suction line.

4. Completely empty the pump.

9.8.2

Procedure

Impeller

3.

WARNING:

Risk of injury when stopping the impeller by

hand. Block the impeller

with a wooden wedge.

Loosen the impeller nut

, and remove with the O-ring

.

4. Take the snap ring

, and the key

off of the shaft.

5. Only for pumps with double shaft seals: Remove the flushing

tubes for sealing or quenching liquid.

TIP: For large pump casings, there is an M 12 thread on the
top of the casing. An eyebolt can be screwed into the thread
for suspension of the pump head from a crane.

6. Pull the pump head with the pump-side shaft seal off of the

shaft as follows:

6a. Clamp connection variant

1. Loosen the clamp bolt.

2. Slightly spread the clamp connection with a wedge.

3. Pull the pump casing out of the clamp connection.

6b. Flange connection variant

1. Loosen the fastening screws on the flange and remove.

2. Remove the pump casing.

7. Take the shaft seal out of the pump casing.

9.9

Checking of the Clearances

The position of the impeller is determined by the position on
the shaft. The clearances are set through the position of the
pump casing with respect to that of the impeller.

Note: For clearances, refer to table 6-8.

Prerequisites

– Pump casing is connected firmly to the lantern.

– Pump cover has been removed.

– The impeller has been mounted and the impeller nut tight-

ened.
