6 Maintenance
! Flawed maintenance will result in shorter lifespan, possible break down and
in any event loss of warranty.
6.1 Precautionary measures
• Insufficient, wrong and/or irregular maintenance can lead to malfunctions
in the pump, high repair costs and long-term inoperability. Therefore, you
should carefully follow the guidelines given in this chapter during
maintenance operations on the pump. Non-compliance with prescriptions
or warnings may be dangerous for the user and/or seriously damage the
pump / pump group.
• All work should be carried out by suitably trained personnel.
• Pump and piping may contain high pressure liquids, high temperature
liquids or/and hazardous chemical fluids even when the unit has been shut
down. Before dismantling, always allow the pump to cool (20 °C) and allow it to drain
completely.
• Ensure that the working area is clean, because certain parts such as the mechanical
shaft seals are extremely vulnerable and others have very close tolerances.
• Installation, operation and maintenance has to be done by qualified and well prepared
personnel.
! In case of storage :
• The pump must be operated briefly once a week or alternatively one manually makes a
full revolution of the pump shaft.
• This ensures a proper circulation of the protective oil.
6.2 Daily
• Keep both the surface of the pump and the surroundings as clean as possible. This
simplifies inspection (attached markings remain visible).
• Never spray the hot parts of a pump with water, as certain components may
crack due to the sudden cooling and the fluid being pumped may spray in to
the environment.
6.3 Periodic inspection
• The pump should run smoothly and free from noise or vibration
• Shaft alignment and levelness of the base plate
• Gasketed seals at pump casing and seal cover and suction / discharge connections
should be inspected for leaks.
