5.4 Recommended stocks of spare parts
Seal set
We recommend that you keep both seal kits and service kits for the
W+ pumps in stock. The seal kit for the W+ pump consists of the
wearing parts of the pump, as specified on page 28.
Service kit
The service kit is made up of a number of the main components of the
pump which are not wearing parts, but which you still may have to
replace: shaft, impeller, cap nut and fixing kit.
The table below shows the recommended stocks of spare parts for
normal operation and in cases where there are special needs - for
example 24-hour operation, operation with abrasive media, or proces-
ses that are sensitive to even the shortest production stoppage.
