(continue)
Please note:
e direction of flow can be adjusted by turning the pump chamber in 90°
steps.
e Quattroflow 1200 S is self-priming and can run dry. Inside the pump
chamber there are no rotating parts that might cause heating up of the product
or shed particles.
e pump-motor unit is mounted on a stainless steel base plate. In case that
the pump will not be operated on the base plate but for example in a frame, a
perpendicular mounting position is possible.
Start-Up Before start-up of the pump one should acquaint oneself with the explanations
of the troubleshooting. Only by doing this can defects be quickly realized and
eliminated in case of trouble. Problems which cannot be solved or with an
unknown reason should be passed on to the manufacturer.
Prior to each use we recommend to flush the pump with a proper fluid (e.g.
water or buffer).
Prior to the very first use it might make sense to clean and sanitize the
pump chamber. A commercial caustic clear and/or 0.1 to 0.5N NaOH can
be applied. e chosen cleaning agent can be recirculated and also stored
inside the pump chamber. For Flushing out of any cleaning agent do not
recirculate! Check with appropriate analytical methods the success of the
flushing procedure.
Recommendation: Test run prior first use!
Before using your pump in your process perform a test run to get
used to the specific properties of the pump.
Pay attention to have sufficiently dimensioned piping. Too small
of for the suction line can cause cavitation as well as a loss of
performance.
If hoses are used in the suction line, make sure that they do not
collapse due to the negative pressure.
When installing the pump please insure that around the pump
enough space is available for the operation and maintenance. Pay
attention to the required space needed for assembly and disas-
sembly of the pump chamber.
During start-up pay attention to the warning and safety instructions
of this manual.

QF1200 S Pump Description
Cleaning (CIP) Depending on the products in contact with the pump and given requirements
the cleaning procedure needs to be adapted accordingly. It is the responsibility
of the user to verify the cleaning efficiency. Safety rules and safety measures like
protective glasses, gloves, and protective clothing have to be followed and used
when working with chemicals like sodium hydroxide (NaOH).
Autoclave For sterilization of the pump chamber we recommend the following steps.
1. CIP of the pump chamber according to 2.4 or any other suitable process.
2. Empty the pump
3. Remove the pump chamber from the pump drive.
4. Close the in and outlet of the pump (e.g. by connecting hoses). Make sure
that there is free interchange available of gas and steam over a sterile barrier
(e.g. sterile filter) at the in and outlet.
5. Autoclave the prepared pump chamber in a vacuum at max 130°C (266°F)
for max 30 min. Follow the instructions from the autoclave manufacturer.
As a general rule we recommend to clean the pump according to the following
procedure.
1. Pre rinse the pump with pure water, until residual amounts of product have
been removed.
2. Cleaning step with 0.5 M NaOH (ca 50°C) at 80% of the maximum RPM
for approximately 30 min. Check before, if surrounding conditions (e.g. pipe
diameter, system pressure rating) allow to operate the pump at this speed.
3. Final rinse with pure water, until neutrality has been achieved (e.g. by
measuring conductivity or pH of the rinse water).

Steaming in Place
(SIP)
For steaming in place the pump chambers need to be installed on the pump
drive. During the steaming process, the temperature in the pump must not
exceed 130°C (266°F) and should not last longer than 30 min. e cooling of the
pump chamber should be against air. Depending on the SIP conditions it may
be necessary to shorten the maintenance intervals for the elastomers significantly.
Tightening torques (10 Nm, 7.4 lb-ft) of the front bolts of the pump chamber
must be checked after each SIP cycle.

Safety Maintenance,
Inspection and,
Mounting Operations
• Basically, operations at the pump must be performed during standstill only.
e motor has to disconnect from the power supply, e.g. by pulling out the
power plug or using a repair switch, and has to be secure against unintention-
al switch-on. is can be realized by a lockable emergency switch. To prevent
an accidental re-starting a danger sign should be installed.
• e operator must ensure that all maintenance, inspection and
installation work is performed by authorized and qualified skilled
personnel acquainted themselves with this manual.
• Before starting to disassemble the pump, take care that the pump has
been emptied, rinsed, depressurized and disconnected at all phases of
the power supply. Both ports piping are to be closed and drained if
applicable. If the pump is being removed from the plant, a reference
about the delivered liquid has to be attached.
Unauthorized
Modifications
• Pumps or aggregates handling noxious fluids (e.g. caustic, biohazards) must be
decontaminated. Immediately following completion of the work, all safety
relevant and protective devices must be re-installed and/or re-activated before
being put back into operation, take care of the mentioned instructions of the
chapter “start-up” and check the tightness of the pump.
• Please respect the relevant additional security advises, if the pump has been used
for aggressive, dangerous or toxic liquids (e.g. suitable protective equipment
according to the safety data sheet of the liquid). In case of a diaphragm rupture,
it is possible that residues of the liquid remain behind the diaphragms and in
the area of the ring drive. Hence, appropriate safety equipment according to the
safety data sheet of the liquid is indispensable.
• Especially when delivering critical liquids, wear parts, like diaphragms, should
be replaced within a preventive maintenance.
• Procedure for pump return: According to the requirements of our 14001
certification, every unit which is sent to Masterflex or ALMATEC for
diagnosis or maintenance reasons has to be accompanied by a filled out
decontamination-sheet. Otherwise a processing is not possible. e
decontamination-sheet is enclosed in this manual. Please pay attention to the
further safety regulations.
e use of non-original Quattroflow spare parts or non authorized accessories
and reconstructions lead to the void of the warranty immediately. When operat-
ing such a pump, damages of properties and/or persons cannot be excluded.
Invalid Modes
of Operation
A safe operation of the pump is ensured only by an appropriate use according to
the specific data of the enclosed pump data sheet. e values limitations given in
the data sheet must not be exceeded.

Additional Safety
Warnings
These warning hints are to prevent the user from an inadmissible mode of
operation. These warning hints are to be strictly followed to avoid any
damage to the pump and/or any danger to personnel.
e maximum allowed discharge pressure depends on the temperature of the
fluid: P max at room temperature = 6 bar (>40°C = 4 bar) [=87 psi (>104°F =
58 psi)]. Exceeding of the maximum allowed discharge pressure must avoided
in any case (do not remove the warning sign at the pump). As a result even if
only temporarily – exceeding the allowed discharge pressure, the diaphragm can
be damaged. e resulting leakage may lead to a loss of the pumping fluid and
damages of properties and/or persons. Pay attention to a sufficiently
dimensioned piping on the suction and discharge line to prevent too high of
pressure in the pump. e pump chamber may not be set under pressure when
it is not mounted on the drive.
P
MAX: 6bar
• e free cross section of the suction side as well as the length must be
measured in such a way to avoid cavitation.
• e use of a safety device (e.g. pressure switch) can be necessary.
• Please make sure that prior to the start of the pump the discharge line is
checked. Make sure that there is no flow restriction in the discharge line to
avoid any over pressure (e.g. closed valve).
• Flush the pump prior to use with appropriate fluid (e.g. buffer).
• Foundation design: e foundation must be designed so that it can take the
weight of the pump aggregate on the entire surface.
• Please make sure that the pump is operated with the proper mains voltage and
frequency to avoid damages and electrical danger.
• Make sure that the slots for the cooling air are not blocked
• Due to the versatile possibilities to use the Quattroflow pump it is highly
recommended to check case by case if the pump will be the right tool for
the specific application. e user/operator is responsible to perform a proper
method of testing if the pump should be applied for his specific application.
e chemical and thermal compatibility of the elastomeric parts of the pump
with the fluid that will be pumped are to be checked by the operator before
the first process run. E.g. Oily, fatty fluids or solvents might cause a swelling
and/or destruction of the elastomeric components. If in doubt, please
contact the manufacturer!
• Operating the pump in humid or aggressive air can cause damages to the
motor and control box.
• e control box should not be exposed to spray/splash water or to heat
sources.

Safety
Additional Safety
Warnings (Continue)
• Depending on the conditions of operation, the liquid conveyed might escape
from the pump in case of a diaphragm rupture. For further safety requirements
the optional equipment diaphragm monitoring is recommended.
• Pools of liquid which appear in the near outer area of the pump have to be
inspected on danger potential, if necessary safety measures are to be taken.
• Chemical and biological reactions in the product chamber of the pump (mixture
of different substances) and the freezing of the liquid have to be avoided.
• To avoid corrosion the contact of aggressive solutions (e.g. NaCl, HCl) with the
outer stainless steel surfaces of the pump (e.g. hood, base plate) has to be
prevented.
• e Quattroflow pump is a positive displacement pump and can theoretically
generate an infinitely high pressure even at low speed (rpm). Prior to each start
of the pump check and make sure that the discharge line is not closed or
restricted. e design of the discharge line must not build up a pressure of > 6
bar (78 psi).
• If suction and/or discharge line are flexible tubing, then make sure that these
tubing do have the proper pressure rating for the full range of temperatures that
are applied.
• Please follow the general safety guidelines when handling chemical fluids (wear
gloves and/or glasses) before the pump chamber will be opened.
• Never operate the pump without coupling protection and motor housing.
• Quattroflow pumps can lead to bruises when lifting, sinking or assembling them.
Appropriate accessories and safety equipment are to be used. Big and heavy
modules have to fixed and secured to lifting gears when transporting/replacing
them.
• Disconnect mains before doing any maintenance! e housing of the control
box or the motor is to be opened only by skilled personnel. Check the electrical
cables before connecting to mains supply.
• During all maintenance work it has to be ensured that no explosive atmosphere
can arise. Appropriate protection equipment is recommended. e Quattroflow
1200 S must not be operated in explosion-proof areas. Special versions for
“ATEX” applications are available. Please contact the manufacturer.
Attention!- Inadmissible modes of operation, arbitrary reconstruction,
spare parts production and/or any changes of the design (without permission
of the manufacturer) may cancel the liability resulting there from.

Section 4
Maintenance/Servicing
Section 4 Maintenance/ Servicing
Due to the robust construction the Quattroflow pump are widely maintenance free.
e ball bearings do not need any extra lubrication.
e diaphragms, valves, and O-rings should be checked in regular intervals and if
needed they have to be replaced. We recommend the following maintenance intervals
for the different pump parts:
Depending on the operation conditions (pressure, temperature, flow rate, SIP, etc.) it
may be necessary to shorten the maintenance intervals for the elastomers significantly.
In case that the diaphragm is broken the pump chamber should be replaced. At that
time is also recommended to check the ball bearings. For corrosion reasons or a clearly
audible operating noise the parts of the bearing service kit should be also replaced.
Please follow the general guidelines and safety advise when
handling with chemicals.
Disconnect mains supply before opening the pump housing!
Basically, operations at the pump must be performed during stand-
still only. The motor has to be disconnected from the power supply,
e.g. by pulling out the power plug or using a repair switch, and has
to be secure against unintentional switch-on. This can be realized by
a lockable emergency switch. To prevent an accidental re-starting a
danger sign should be installed.
