Exchange materials
Packings and seals are normally always replaced when pumps or valves are overhauled. Mechanical seals are checked and then repaired or replaced.
Sometimes, however, it is only possible to determine which components still need to be replaced after disassembly.
These include
Many of these consumables are in stock at our company or at our co-operation partners.
Regeneration
Components that are only worn at functional points can often be regenerated by welding on the worn areas. This applies, for example, to industrial knives or cutting tools in the wood or paper industry, worn shafts with partial wear, pump impellers, etc.
In many cases, it is possible to achieve a longer service life of the regenerated component compared to the original part by hardening the functional area.
The same applies to protection against corrosion.
New production / design adaptation
The production of a completely new component makes sense if the original part cannot be procured, can only be procured with an unsatisfactory delivery time or only at extreme cost.
It is also possible to adapt the design of completely new parts to their intended use. Examples of this are welded constructions as replacements for castings, the application of wear protection coatings at potential wear points or the modification of dimensions depending on the load.
