tioned in the contract can be defined! If strong vibrations occur during operation, the
pump and the installation must be checked regardless of the defined maintenance in-
tervals.

▪ Visual inspection of the power supply cable

▪ Visual inspection of accessories
▪ Visual inspection of the coating and housing for wear
▪ Function test of monitoring devices

15000 operating hours or after 10 years at the latest
▪ General overhaul
Under harsh operating conditions, specified maintenance intervals must be shortened if
required. Harsh operating conditions include:
▪ Fluids with long-fibre components
▪ Turbulent inlet (e.g. due to air intake, cavitation)
▪ Strongly corroding or abrasive fluids
▪ Heavily gas generating fluids
▪ Operation at an unfavourable duty point
▪ Pressure surges
When using pumps under hard conditions, it is recommended to sign a maintenance
contract. Contact customer service.
WARNING
Sharp edges on the impeller and suction port!
Sharp edges can form on the impeller and suction port. There is danger of limbs be-

Danger of (serious) injuries during work. Wear the following protective equipment:
• Safety gloves for protection against cuts
• Safety shoes
• Closed safety goggles
The following pre-requisites must be fulfilled prior to starting maintenance measures:
▪ Pump cooled down to the ambient temperature.
▪ Pump cleaned thoroughly and disinfected (if required).
The power supply cables must be checked for:
▪ Bubbles
▪ Cracks
▪ Scratches
▪ Abrasion
▪ Crushing
If the power supply cables are damaged, the pump must be decommissioned immedi-
