Spare parts
Spare pumps kept for stand-by usage
When you stock spare, stand-by pumps, consider these guidelines:
• In plants where failure of a pump could endanger human life or cause damage to property or high
costs, you must keep a sufficient number of stand-by pumps in stock.
• Store stand-by pumps according to the instructions in Transportation and Storage.
Spare parts stock guidelines
When you stock spare parts, consider these guidelines:
• Stock spare parts in order to ensure two years of continuous operation.
• If no other guidelines apply, stock the recommended number of parts listed in the spare parts table.
• Make sure that you maintain an adequate number of spare parts, especially parts that require longer
delivery times:
• Mechanical seals
• Parts made from special materials
• Parts that need to be specially sized
• Store spare parts in dry, clean areas in their original packaging until you need them.
