5.4 Recommended stocks of spare parts
Seal sets
We recommend that you keep both seal kits and service kits for the
Ws+pumps in stock. The seal kit for the Ws+pump consists of the
wearing parts of the pump, as specified on page 34 ­ 35.
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 24­hour operation, operation with abrasive media, or
processes that are sensitive to even the shortest production stoppage.
