The centrifugal pump delivering the washing solution is
generally calibrated to a higher troughput than 10 m

/h,
therefore a pump bypass circuit must be provided for
(see fig.3).

Indeed, in this case, the pressure at entry to the S6C
pump is lower than the exit pressure and the piston
remains stuck against the cylinder. The S6C pump is not
flushed through. Its good cleaning is therefore no longer
ensured and the cylinder/piston couple will be prematu-
rely worn.
In the case of assembly in "parallel" (discharge of the
centrifuge pump to the discharge of the S6C pump), the
2 pumps must never be run at the same time. In this
case the S6C pump cleans itself.
4.4 Sterilisation In Place (SIP)
The serie S pumps are perfectly adapted to all pro-
cesses using SIP (Sterilisation In Place): pump
stopped / maximum 20 mn per cycle / 1 or 2 cycles
per day.
