OPERATOR Book No.: 95-0014-0000/A HANDBOOK Issue: SAFETY PRECAUTIONS WARNING. ALL ITEMS IN THIS SECTION, IF NOT STRICTLY OBSERVED, COULD RESULT IN SEVERE PERSONAL INJURY OR LOSS OF LIFE. Only use lifting equipment of suitable capacity for the size and weight of the equipment being lifted. The pump units are designed for lifting by wire rope in use or slings around the workshop.
OPERATOR Book No.: 95-0014-0000/A HANDBOOK Issue: INSTALLATION General Notes Xylem Dewatering Solutions may refute warranty liability if the installation does not meet the requirements of the pump. Consult Xylem Dewatering Solutions should any doubt exist over the suitability of an installation. Only suitably qualified personnel (both mechanical and electrical) should carry out the installation.
5.2.2 Front seal removal The bearings (and mechanical seal for HS80 units) of HS80, HS100, HS150, HS100-SG, HS150V, HS150V-SG, HS100NC and HS150NC pumps are designed to be lubricated and cooled by the hydraulic motor system oil. The oil is bled from the motor by removing the seal from the front cover.
Remove the key (36). Figure 5 Typical HS80 pump Release the screws (72) holding the rear wear plate (5) to the bearing bracket assembly. Remove the wear plate to expose the mechanical seal housing (8).
OPERATOR Book No.: 95-0014-0000/A HANDBOOK Issue: 7.1.2 Reassembly New seals and O-rings must be fitted when reassembling. It is also prudent to fit a new impeller retaining screw. Heat both bearings (39 & 40) with a temperature controlled bearing heater until they are a consistent 110°C. Do not overheat or allow the bearings to remain at this temperature for longer than their fitting time.
OPERATOR Book No.: 95-0014-0000/A HANDBOOK Issue: HS100, HS100-SG, HS103, HS150, HS150-SG, HS150V & HS150V- SG pumps NOTE! The HS100NC & HS150NC pumps differ only in volute, impeller and associated parts. Therefore these dismantling and reassembly instructions can be followed in principle, but refer to section 7.5 for detail differences. Note that dismantling and reassembly procedures refer to the item numbers in the illustrations and are correct for a directly corresponding build.

OPERATOR Book No.: 95-0014-0000/A HANDBOOK Issue: 11. Release the nuts (65) holding the hydraulic motor (76) to the bearing cover (11) and remove the motor. 12. HS100 only. Undo the screws (60) and remove the bearing cover (11) from the bearing bracket.
OPERATOR Book No.: 95-0014-0000/A HANDBOOK Issue: 7.2.2 Reassembly New seals and O-rings must be fitted when reassembling. It is also prudent to fit a new impeller retaining nut. Heat both bearings (47 & 48) with a temperature controlled bearing heater until they are a consistent 110°C. Do not overheat or allow the bearings to remain at this temperature for longer than their fitting time.
OPERATOR Book No.: 95-0014-0000/A HANDBOOK Issue: HS150HH, HS200-SG, HS200 & HS250 pumps Note that dismantling and reassembly procedures refer to the item numbers in the illustration and are correct for a directly corresponding build. However because of the number of possible build configurations some interpretation of the diagram will be necessary for other pump variants.
OPERATOR Book No.: 95-0014-0000/A HANDBOOK Issue: 11. Release the nuts (69) from bolts (54) and remove the lifting bracket (11) and adaptor (8) from the bearing bracket assembly. 12. Release the screws (57) holding the hydraulic motor (84) to the bearing cover (77) and remove the motor. 13.

OPERATOR Book No.: 95-0014-0000/A HANDBOOK Issue: Once up to temperature, slide the roller bearing (89) inner race up hard against the shaft shoulder, fit the bearing spacer (78) and slide the angular contact ball bearings (2 off 90) up hard onto the other shaft shoulder. Hold them in position for a minimum of 30 seconds.
OPERATOR Book No.: 95-0014-0000/A HANDBOOK Issue: HS300 pumps Note that dismantling and reassembly procedures refer to the item numbers in the illustration and are correct for a directly corresponding build. Figure 13 HS300 cross section 7.4.1 Dismantling The HS300 arrangement differs from the rest of the range because of the extra weight and bulk of the unit. It has an external lifting bracket.

OPERATOR Book No.: 95-0014-0000/A HANDBOOK Issue: Using suitable lifting gear rotate the whole unit 90° until it is resting with the shaft horizontally and the pump mounting foot towards the ground. Remove the 4 off nuts, bolts and washers (81, 74 & 62) holding the strainer to the frame. Support the strainer (10) and remove the 8 off nuts, bolts and washers (81, 74 &...
OPERATOR Book No.: 95-0014-0000/A HANDBOOK Issue: 7.4.2 Reassembly New seals, O-rings and impeller retaining screw must be fitted when reassembling. Heat the roller bearing inner race (part of 24) and both angular contact ball bearings (2 off 25) with a temperature controlled bearing heater until they are a consistent 110°C.
OPERATOR Book No.: 95-0014-0000/A HANDBOOK Issue: 26. Fit 4 off studs (67) every other hole in the pump body. Fit 4 off studs (68) in the remaining holes. Pass the front cover assembly over the studs and secure with 4 off nut and spring washers (74 & 81) on the shorter studs. 27.
