▪ 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.
