Commissioning

Commissioning refers to the time when a machine or system is used for the first time by the operator, which is only permitted if compliance with the related requirements has been documented in accordance with relevant EC directives such as the Manufacturer's Declaration and CE marking.

In the context of centrifugal pump technology, to ensure fault-free pump operation, it is not only the condition of the pump that needs to be taken into account from the time of delivery up until the time of commissioning, but also the condition of all the components that come into contact with it (e.g. foundation).

Overall measures for fault-free operation 

General

• Checking the pumps and their accessories to ensure that everything has been included in the delivery and that no damage has occurred in transit.
• Organising and supervising proper and competent on-site transports of equipment to the pump foundation
• Getting the pumps ready for operation
• Checking all the equipment installed for the purpose of protecting the pumps
• Instructing the customer's personnel regarding the functions and handling of the pumps and/or systems

Checks

• Checking whether the dimensions of the foundations, recesses and passages are adhered to and in line with the approved foundation and general arrangement drawings
• Checking whether the foundation bolts and frame are properly grouted without any shrinkage
• Checking the flushing operation and pumps of the oil systems
• Checking fine strainer inserts to be provided in inlet lines
• Ensuring that pumps, gear units and motors are properly installed on the foundations without warping or twisting so that impermissible vibrations and premature damage are avoided 
• Ensuring that piping connections are laid without subjecting them to any stresses or strains and carrying out any subsequent checks that may be necessary after adapting the piping
• Alignment of pumps, gear units and motor couplings according to the manufacturer's instructions
• Final precision alignment of pump, gear unit and motor, as well as monitoring this
• Checking the direction of rotation 

Monitoring

• Ensure assembly steps are carried out in the correct order as per the operating manual
• Assembly of auxiliary systems (automatic recirculation valves and piping, oil supply and cooling systems)
• Fill level of oil and bearing lubrication systems
• Commissioning, test runs and trial operation including documentation of key operating data
