Make sure that the pump is always promptly and adequately
cleaned. To do so, you may consider, among other things,
including your pump in your operational cleaning schedule. Alter‐
natively put in place other or additional appropriate measures and
methods to ensure that there is no, or could be no, hygienic risk to
the process.
Make sure, when cleaning too, that all hygienic conditions at the
installation site, workplace, tools, equipment etc. are guaranteed
and complied with during any associated work.
If water is used as the cleaning agent, auxiliary agent etc. during
cleaning, then this water must be of drinking water quality.
Make sure that all surfaces, especially any surfaces that come into
contact with food products, are not scratched by tools, cleaning
agents, auxiliary agents etc., and that these surfaces are not
changed in any other way.
