6.4.3 Autoclaving of the pump chamber
Autoclaving is sterilisation by thermal treatment under overpressure. The pump chamber may only be
autoclaved when the pump chamber has been removed.
►
Empty the pump completely.
►
Clean the pump according to the fluid.
►
Disassemble the pump chamber (see chapter 6.5.2 Disassembling the pump chamber on page 33).
►
Close the inlet and outlet openings of the pump, e.g. by connecting hoses. Make sure that a free gas and
steam is possible directly or indirectly via a sterile barrier (e.g. sterile filter) at the inlet and outlet
openings.
ATTENTION
–
The diaphragms can be deformed in the autoclave. Do not exert pressure on the clamping
ring (Figure 23) during autoclaving.
►
Position the pump chamber in the autoclave as shown.
