9 Servicing and cleaning
requirements
Scheduled maintenance
The polyamide rollers and the stainless steel drive shaft run on sealed bearings and
do not require lubrication. The sun gear of the gearbox in the 701 ATEX pumpheads
should be lightly greased with a quality gear grease every one thousand hours and
after cleaning.
If fluid is spilled inside the pumphead, flush the pumphead out with water and mild
detergent as soon as possible. If specific cleaning agents are required to clean the
spillage, please consult Watson-Marlow Technical Support Office before proceeding,
in order to confirm chemical compatibility. The same cleaning procedure should be
used to limit the build-up of dust (which can become electrostatically charged and/
or heated by friction).
Because of the importance of dissipating any electrostatic charge, the earthing lead
should be regularly checked for signs of corrosion.
Tube loading
The 701RA pumphead requires continuous tubing, while the 701REA pumphead
operates with Watson-Marlow LoadSure tube elements. Specific tube loading
instructions are contained within “Watson-Marlow 701 baseplate pumps” which can
be found on the E-manuals CD supplied with each pumphead (CDR0600).
For both pumphead types, extension pumpheads are also available.
