The above materials have been carefully selected and have a well proven track record.
However, if there are any aggressive chemicals present then it is imperative that a risk
assessment is conducted. This must not be limited to just the pumped fluid but should
also include any other aggressive fluids in the intended operating environment.
9 Tube materials in ATEX applications
The following Watson-Marlow tube materials are suitable for use in ATEX
applications:
● Pumpsil (platinum-cured silicone) ● Marprene ● Bioprene
● STA-PURE PCS ● STA-PURE PFL .
Please note from the table below that there are limitations of length that can be
used for certain tube materials. Pumpsil cannot be used in any ATEX application
above the specified lengths listed. When using Bioprene and Marprene there is a
reduction in class suitability when they are in contact with Polymides.
10 Servicing and cleaning requirements
If aggressive liquids are spilled onto the pumphead, the head should be removed
and cleaned with a mild detergent. Remove any tubing from the pumphead.
The same cleaning procedure should be used to limit the build-up of dust (which
can become electrostatically charged and/or heated by friction).
The moving parts of the rotor should be checked from time to time for freedom of
movement. Pivot points and rollers should be lubricated occasionally with Teflon
lubricating oil.
The rotor shaft runs on sealed bearings which do not require lubrication.

12 Replacements
Spares and replacements should be ordered through Watson-Marlow pumps or
through an offical representative. Only Watson-Marlow spares and replacements
should be used in order to guarantee continued compliance with the ATEX directive.
Watson-Marlow's policy is to provide spare parts for all products for a minimum of 7
years from discontinuation. The ability to implement this policy is not entirely within
Watson-Marlow's control and cannot be guaranteed, but every effort will be made to
honour this policy.
