Hy~Line and Ultima Lobe Pumps
4. CIP fluid flow should result in a mean
pipeline velocity of at least 1.5 m/sec.
(5 ft/sec).
If using the lobe pump to circulate the
CIP fluid, refer to the Performance
Data Sheet for pump speed to give
required flow, taking account of
pressure losses through pipework.
Note that all pumps are more
susceptible to cavitation when
pumping hot liquids. Ensure adequate
Net Inlet Pressure available.
If using a separate pump to circulate
CIP fluids, the lobe pump may need to
be rotated at a speed sufficiently high
to allow the fluid to pass freely through.
If sufficient pipe velocity cannot be
achieved, fit a by-pass loop to divert
excess flow past the pump.
CIP fluid pressures must equal or
exceed process pressure at all points
in the system to ensure fluid reaches
all contact surfaces. It may be
necessary to restrict flow in discharge
pipework to achieve this but do not
exceed differential pressure and
temperatures shown on pump
Performance Data Sheet. A minimum
differential pressure of 1 bar is
recommended for effective cleaning.
5. After CIP, rinse through with
neutralisers and clean water to remove
all traces of cleaning agents.
Do not pass cold liquid through pump
immediately after hot - allow
temperature to change slowly. Failure
to observe can result in pump seizure.
Procedure for Manual Cleaning
See elsewhere in this manual for
procedures to dismantle and re-assemble
fluid contact parts. Ultima pumps are not
intended to be manually cleaned - Instead
specify a Hy~Line pump which is designed
to be stripped more easily for cleaning.
Take care not to scratch or damage
pump parts. One part of the seal face
remains in the rotor when it is
removed. Be extremely careful not to
damage this seal face.
Do not use steel abrasive wool or brushes
on fluid wetted surfaces as particles may
become embedded in the surface and cause
corrosion.
Use suitable cleaning agents in accordance
with their manufacturer’s instructions
regarding temperatures, dilutions, skin
contact precautions and other safety
information. Thoroughly clean all fluid
contact surfaces and rinse as required.
As a minimum it will be necessary to remove
the end cover and rotors. Re-assemble
pump in accordance with this manual.
5.02. STERILIZING IN PLACE
It is possible to pass steam through the
complete assembled system to sterilize the
internal surfaces without dismantling the
pump.
