Care and maintenance
2/4
Shims (P) between the case and bearing frame are used to adjust the front running
clearance between the impeller and the case. For ease of assembly, case fixings (B)
locate in slots around the frame's front flange. The inner flange of the frame provides a
spigot for an expeller ring or a stuffing box. Threaded holes are provided in the flange for
withdrawal screws (E).
Openings (F) in each side of the body give access to the gland and water flushing
connection if fitted. Lubrication points are provided for the bearings. Other openings in
the top (G) or side of the frame body give access to the bearing cylinder tension screws,
saddle screws and impeller adjustment screw.
2. Inspection of wearing parts
Inspection of wearing parts can be carried out by either removing the case or by removing
the bearing frame assembly, ie. front or back pull-out method. The method will depend on
the installation and ease of access to the pump.
The "back pull-out" method simplifies inspection and site maintenance. Alternatively, the
pumping parts can be removed from the front after removing the pipework.
Figure 9.5.2-2 Using back pull-out method avoids having to disturb the pipe-work
3. Preparing for disassembly
Figure 9.5.2-1 and parts list drawings in section 10.4 identify parts referenced in this
section.
a) Run the pump on clean water or flush clean the inside of the case.
b) Isolate the pipework and drain the pump case.
