▪ Maintenance tasks: The technician must be familiar with the use of operating fluids and
their disposal. In addition, the technician must have basic knowledge of mechanical en-
gineering.
▪ Provide the necessary protective equipment and make sure that the personnel wears it.
▪ Collect operating fluids in suitable tanks and dispose of properly.
▪ Dispose of protective clothing used in accordance with regulations.
▪ Use only original parts of the manufacturer. Use of parts other than the original parts
releases the manufacturer from any liability.

ing on the real ambient temperatures, maintenance intervals different from those men-
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.
4000 operating hours
▪ Visual inspection of the connection cables
▪ Visual inspection of accessories
▪ Visual inspection of the housings for wear
▪ Function test of monitoring devices
▪ Oil change
15000 operating hours
▪ Complete 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.
