Recommended Spare Parts Kits

and tool kits

Every shutdown for service of a plant is costly.

The time for repair should therefore be limited to

a minimum which can be accomplished by keep-

ing a spare pump. The changed pump can later be

repaired at a suitable place and can then be used as

a spare pump. For maintenance the following spare

parts kits and tools are recommended:
