are recommended when changing the oil:
▪ Aral Autin PL*
▪ Shell ONDINA 919

▪ Tripol Molub-Alloy-Food Proof 823 FM (with "USDA-H1" approval)
Refer to the supplied configuration for the filling quantities.
To ensure reliable operation, maintenance tasks must be carried out regularly. Depend-
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.
8000 operating hours or after 2 years at the latest

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.
