6 .3 .2 - PUMP CASING CLEANING
This operation is necessary when a hose has burst and when the product has contaminated the inside of the pump
casing. Perform these steps with caution. If hazardous chemicals were being pumped, use caution when removing the
lubricant.
1 - Unfasten cover screws by leaving two screws partly fastened to the casing. Slightly withdraw the cover from the
casing and fix a shackle in one of the cover's highest fastening holes (see picture below). Pumps ALH80, ALH100 and
ALH125 are equipped with a lifting ring. Install a lift equipment in this shackle and slightly raise the cover. Unfasten the
remaining screws and withdraw the cover. For cover weight please refer §9.12
2 - Check the state of the cover seal (REF 10) §6.4.1 and replace if necessary.
3 - Check the state of wear of the pressing shoes (REF 5) and replace them if necessary, see §6.4 Replacement of spare
parts.
CAUTION! Worn shoes can contribute to improper compression and premature wearing of the
hose.
4 - In the case of a hose burst, it is possible that the shaft seal (REF 26) §6.4.2 as well as the seal ring (REF 27)
§6.4.2 have been notably damaged when pumping an abrasive liquid. Relate to §6.4 if a replacement of these parts is
necessary.
5 - Wash the casing with clear water and withdraw any residues.
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
without a mounted cover.
For Torque settings (hose clamps and brackets), refer §9.11
1 - Pre-assemble the flange (REF 47) at the inlet port with two bolts (photo 1).
2 - Clean the new ALBIN hose carefully. Slightly coat it with ALBIN lubricant.
Lightly lubricate the inside of the sleeve (REF 6).
