2.3.2 Installations with SIP-systems, Sterilising In Place
TopLobe pumps are capable of handling a SIP-process.
Contact SPX Process Equipment for information regarding the temperatures needed for
the process, as temperature has an effect on the clearances in the pump.
Equipment components may need sterilising, i.e. heating to high temperatures (up to
140°C) to kill organisms still remaining on the surface of the equipment. Sterilising is
done by using steam or pressurised, heated water.
2.4 Start
Make sure that all associated equipment is clean and free from debris and that all
•
pipe connections are secure and correctly sealed.
For pumps fitted with quenched/flushed product seals check that all required services
•
for flushing purposes are in place and connected. They must give sufficient flow and
pressure for the flushing purposes. Contact SPX Process Equipment for advice. For
seal plans, see ’’E, F, G, H manuals’’ respectivley.
Check the lubrication for the pump and drive. The TopLobe pumps are delivered
•
without oil and should be filled to the level of the oil level glass. See “Section 3.2’’
regarding pump oil capacities and grades.
If an external relief valve is incorporated in the system, check that it is set correctly.
•
It is considered good practice to set the relief valve lower than the system design
pressure. After commissioning, the relief valve should be reset to the required setting
for the application. The required setting should never exceed the lower of either
the pumps maximum pressure rating or the system design pressure setting for the
application. The required setting should never exceed the lower of either the pumps
maximum pressure rating or the system design pressure.
e) The base plate must be secured to a flat level surface to avoid misalignment and
distortion. When the baseplate is fastened in position, the alignment must be
checked again, see point b.
f) If the pump is driven by an electric motor, check that the motor and other
electrical equipment are compatible with the drive and that the wiring is correct,
i.e. Direct On-Line, Star Delta etc. Ensure that all components are correctly
electrically grounded.
2.3.1 Installations with CIP-systems, Cleaning In Place
The TopLobe pumps are constructed so that they easily can be cleaned with CIP-
methods for cleaning of processing plants. To achieve the necessary fluid velocities
within the pump when cleaning we recommend a differential pressure of 2-3 bars across
the pump.
Recommendation: A built-on safety relief valve with air lift, creates the possibility to
achieve a full flow in the pipe work without using separate by-pass piping.
