7.5.1 General information/Safety regulations
WARNING
Improper lifting/moving of heavy assemblies or components
Personal injury and damage to property!
▷ Use suitable transport devices, lifting equipment and lifting tackle to move
heavy assemblies or components.
CAUTION
Improper reassembly
Damage to the pump!
▷
Reassemble the pump (set) in accordance with the general rules of sound
engineering practice.
▷
Use original spare parts only.
Sequence Always reassemble the pump in accordance with the corresponding general assembly
drawing or exploded view.
Sealing elements Check O-rings for any damage and replace by new O-rings if required.
Always use new gaskets, making sure that they have the same thickness as the old
ones.
Always fit gaskets of asbestos-free materials or graphite without using lubricants
(e.g. copper grease, graphite paste).
Assembly aids Avoid the use of assembly adhesives if possible.
Should an assembly adhesive be required after all, use a commercially available
contact adhesive (e.g. Pattex) or sealant (e.g. HYLOMAR or Epple 33).
Only apply adhesive at selected points and in thin layers.
Never use quick-setting adhesives (cyanoacrylate adhesives).
Coat the locating surfaces of the individual components with graphite or similar
before reassembly.
Prior to reassembly, screw back any forcing screws and adjusting screws.
Tightening torques For reassembly, tighten all screws and bolts as specified in this manual.
