Cleaning Procedures
FPL pumps for food and pharmaceutical applications have been designed to minimise areas where
soils can accumulate with consequent user problems.
Areas, which may be liable to accommodate soils, include the connecting faces between diaphragms
and pump body and the divider seal and bushes where fitted.
However these areas are easily accessible due to the one nut and easy access designs of the pump.
CIP (Cleaning in place) can be performed on FPL pumps subject to FPL being aware of this requirement
at time of order and the correct diaphragms being fitted by user when replacement is necessary.
Diaphragms must have a backing plate to support them under CIP loads.
It is strongly recommended that the pump shall be left running, with a minimum air pressure of 2 Bar
(29 psi) while CIP cleaning is carried out. This will assist cleaning the internal areas and prolong
diaphragm life.
It must be noted that when a diaphragm eventually fails in service, product contamination will occur on
contact with the air system.
Most users of pumps on CIP duties will have their own procedures for CIP cleaning.
These may include caustic and antiseptic washes and final rinse hot and cold washes.
It is most important that final washes should be of sufficient time to ensure cleanliness and sterilisation
of all internal areas.
If process conditions are such that CIP cleaning procedures may not be adequate then the pump must
be dismantled and components washed and sterilised by hand and final washes applied again after
assembly. Parts are suitable for industrial autoclaves.
FPL cannot advise on procedures for CIP or sterilisation procedures.
After CIP final wash some liquid will remain in the bottom of pump chambers. Body designs are
available on request to minimise this liquid but are not supplied as standard. This liquid will be in contact
with the product being pumped when the system is operated.
