The pump is designed to require little user maintenance. Observe the
following guidelines when carrying out maintenance on the pump:
▪ Make sure the maintenance is done by a suitably trained and supervised▪
technician. Obey local and national safety requirements.
▪ Make sure the maintenance technician is familiar with the safety▪
procedures which relate to the products processed by the pumping
system.
▪ Check that all the required parts are available and are of the correct type▪
before starting work.
9.2Maintenance plan
More frequent maintenance may be required if the pump is used to pump
aggressive gases or vapours, such as solvents, organic substances and
acids, or if the pump is operated continuously at the higher end of its
operating temperature.
