6. Cleaning 7. Trouble Shooting
Before working on the pump isolate
the power supply securely, then
check that the lines are not live.
• The following tips for fault-finding
are best employed in the sequence
shown.
Pump produces no flow
– Thermal switch has opened due to
over-heating.
• Disconnect pump from mains
and allow to cool. Trace cause of
over-heating and eliminate it.
– Fuses in the pump are defective
(only authorized | qualified person-
nel should investigate this problem)
• Remove the pump from the source
of electrical power by pulling the
power plug.
• At the pump housing, fuses are
located at the IEC plug.
• Fuse ratings: see Table 1.
• Order numbers for fuses: see
Chapter 8.
– Connections or lines are blocked.
– An external valve is closed,
or a filter blocked.
– Liquid (condensate) has collected
in the pump head.
• Let the pump run for a few minutes
pumping air.
• Install the pump at the highest
point in the system.
– Diaphragm or valve plates are worn.
• Section 5 Servicing.
– When changing structured
diaphragm and valve plates, inspect
all parts for dirt before assembling
the pump head and clean them if
necessary.
– As far as possible, clean the parts
with a dry cloth. Only use solvents
for cleaning if the head materials
cannot be attacked (check the
resistance of the material!).
!
Flow, pressure, or vacuum too low
– Compare the actual performance
with the figures in table 2.
– There is pressure on the pressure
side, and at the same time vacuum,
or a pressure above atmospheric,
on the suction side.
• Change pneumatic conditions.
– Liquid (condensate) has collected
in the pump head.
• Let the pump run for a few
minutes pumping air.
• Install the pump at the highest
point in the system.
– The cross-section of pneumatic
lines, or connected components is
too small, or they are restricted.
• To measure the performance,
disconnect the pump from the
system (small diameter tubing or
a valve can significantly affect
performance).
– There is a leak at a connector,
in a line, or in the pump head.
– Diaphragm or valve plates are worn,
or dirt is in the head.
• Section 5 Servicing.
• If the pump does not operate
properly and you cannot find any
of the above faults, send it to the
Sartorios Service Department.
• In order for Sartorius Stedim
Biotech to repair the pump, the
customer must provide a statement
on the media which were pumped
and on pump cleaning. Please fill
out the corresponding Sartorius
Stedim Biotech form, and submit it
together with the pump. A sample
statement for copying can be found
in the Appendix of these operating
instructions.
