Cleaning and disinfection
Cleaning and disinfection of the pump system is of greatest importance when the pump is
used in a food processing installation. Use of a pump system that is NOT cleaned or
disinfected can cause contamination of the product. The cleaning cycles as well as chemicals
to use for the cleaning vary depending on the pumped product and the process. The user
is responsible to establish a suitable cleaning and / or disinfection program according to
local and public health and safety regulations.
2.4.1.
CIP
–
Cleaning In Place (Sanitary pumps)
The importance of easy cleaning is especially great in hygienic applications. Tapflo sanitary
pumps are designed for CIP (cleaning in place). This allows the pump to be internally
cleaned without disassembly. The pump can be cleaned by flushing through with a CIP fluid
(usually a mild solution of sodium hydroxide and a sanitizing additive) or by injection of hot
steam. The CIP fluid temperature varies, but in the sanitary field, the temperature is usually
about 90°C. Make sure that the CIP fluid is compatib
le with the materials in the pump/piping
(consult us for further information).
The solution is passed through the system by either the operation of the pump itself, or by
a centralized cleaning system. The CIP fluid must pass through the pump at a minimum
velocity of 1.5 m/s in the normal flow direction (from inlet to outlet).
It is recommended to run the pump slowly during CIP. This is to obtain pressure balance on
both sides of the diaphragm. Lack of pressure balance will have influence on the pump’s
lifetime. For more information please contact us.
2.5.
Residual risks
Even with proper application and observance of all points listed in this operating manual,
there is still an estimable and unexpected residual risk when using the pumps. It may leak,
fail due to wear, application-related causes or system-related circumstances.
2.6.
Disposal after expiration of the expected lifetime
The metallic components like aluminium, stainless steel and carbon steel can be recycled.
Plastic parts are not recyclable and must be disposed of as residual waste. The pump must
be disposed of properly, according to local regulations. It should be noted that potentially
dangerous fluid residues may remain in the pump and can create a hazard to the operator
or the environment, therefore the pump has to thoroughly cleaned before disposal.
2.7.
Waste of electrical and electronic equipment (WEEE) directive
Users of electrical and electronic equipment (EEE) with the WEEE
marking per Annex IV of the WEEE Directive must not dispose of end
of life EEE as unsorted municipal waste, but use the collection
framework available to them for the return, recycle, recovery of WEEE
and minimize any potential effects of EEE on the environment and
human health due to the presence of hazardous substances. The WEEE
