SIP
SIP means Sterilisation In Place. The pump will be sterilised by
hot steam. For the hot-steam sterilisation or sanitisation,
minimum temperatures of 121 °C must be in contact with all

found in section Technical data, page 10.
The pump should never be operated during the SIP process. After
the SIP process, a cool-down phase of minimum one hour is
needed.
