6.3.2 PUMP CASING CLEANING
Note: The numbers in parentheses are Reference Numbers
located in the Parts List exploded views of this manual.
This operation is necessary when a hose burst has caused
material contamination inside the pump casing.
1. Unscrew cover bolts (33) by leaving two cover bolts partly
fastened to the casing. Partially remove the cover (2) from
the casing and fix a shackle in one of the cover’s highest bolt
holes (4014 is equipped with a lifting ring). Unfasten the
remaining cover bolts and remove the cover. See Figure 6.
2. Check the state of the cover seal (10) and replace if
necessary.
3. Check the state of wear of the pressing shoes (5) and
replace them if necessary. See 6.4.
CAUTION: A wear of shoes can cause problems to the
pump and provoke abnormal hose lifetime.
4. In the case of a hose burst, it is possible that the shaft seal (26)
and seal ring (27) have been damaged when pumping an
abrasive liquid. See 6.4 and Parts List to replace.
5. Wash the casing with clear water and remove any residue.
6. Dry the pump casing entirely.
7. Replace the cover seal in its groove.
8. Reassemble the pump cover.
6.3.3 REASSEMBLY OF THE HOSE
WARNING! You should never assemble a new hose with-
out a mounted cover.
1. Pre-assemble the flange (47) at the inlet port with two
bracket bolts See Figure 7.
FOR MODELS 4003, 4004:
Temporarily mount the bracket 18 at the inlet port.
2. Clean the new Wanner hose carefully. Slightly coat it with
Wanner lubricant. Slightly lubricate the inside of the
sleeve (6).
