General description of the Sterimixer®
The Sterimixer® is a magnetically driven highly aseptic mixer for pharmaceutical, food and
other relevant applications where cleaniness is a requirement. The Sterimixer® may be
supplied as separate components or a complete unit (see picture). The picture below specifies
the different components of the Sterimixer®.
Control box
Impeller
Bearing unit
Weld plate
Magnetic rotor
Drive unit
The Sterimixer® has a mixing capacity for vessels with volumes ranging from 5 to 15000 litres
and for other applications such as stirring up to 40000 litres. The Sterimixer® is available with a
wide range of different options providing flexibility for different applications.
The impeller “aseptic type”, SMA, is ideal for
critical applications due to the creation of a
minimum of shear forces. For efficient CIP
and/or SIP performance the SMA impeller uses a
patented feature involving horizontal flowchannels. The differential pressure created
during rotation, ensures continuous purging of
liquid through the bearing from beneath the
impeller.
The impeller `open type´, SMO, is used within applications where the requirement for low
shear forces and high CIP and/or SIP performance are not critical.
The impeller SMMS, is a medium shear impeller in comparison to the low shear design of the
SMA and SMO. This style of impeller is ideal for incorporation of light or hydrophobic solids
into solutions.
For more information on the different components of the Sterimixer®, refer to section 5
“Sterimixer® Main Parts”.

Welding guide
4.1.1
About the welding guide
The welding procedure described in this guide has been used for welding the weld plates into
Steridose vessels. The guidelines refer only to the technical aspects of welding operations. Do
note that welding currents, time frames etc are approximate and may vary in practice.
NOTE!
Ensure that the vessel is compliant with relevant standards for
pressure vessels.
The most common fault occurring for the weld plate, is deformation introduced when welding
the weld plate into the dished end of the vessel. To minimise the risk of faults occurring after
delivery from Steridose, it is therefore essential that the welding guide is thoroughly studied
and that only properly trained, experienced and qualified personnel are employed in the
welding operations.
4.1.2
General
A weld plate may be welded into the lower dished end, before or after the dished end is
welded to the jacket. For purely practical reasons, it is usually easier to weld the weld plate to
the dished end before the jacket and the dished end are welded together. All other welding on
the lower dished end must however be completed before making a hole for the weld plate.

Information for design and orientation of Weld Plate

The normal position for the
drive unit is 270° as shown in
figure.

The lock nuts on the weld
plate shall then be positioned
in direction 0° - 180° as shown
in figure.

For drive unit 120H/220 and
210/275 there are four lock
nuts. For these drive units the
position has to be 0° - 180°
and 90° - 270°.

If the drive unit will have
another direction, the weld
plate has to be positioned in
accordance to that direction.

4.1.3.3
For best performance, the weld plate has to be mounted as
close as possible to the center of the tank.
Distance from outer edge
Ensure that the weld plate is positioned in accordance to relevant pressure vessel regulation.
Normally, these specify that the weld plate shall be positioned in such way that no part of its
weld is outside the large radius R2 (refer to figure below).
4.1.4
Optimum alignment of Sterimixer impeller axis
The weld plate should be positioned in
the lower dished end allowing the
impeller axis to be aligned as close as
possible to a diagonal through the center
of the vessel. This ensures maximum
mixing effect and minimum risk of
creating a vortex and subsequently the
intake of air
into the product.

Tack welding the weld plate (TIG)
1. The weld plate shall not have the bearing unit or any screws fitted during welding
operation.
2. Position the weld plate in the cut hole of the dished end, ensuring it is properly
orientated in the correct position (refer to 4.1.3.1).
3. Tack weld the weld plate at two points on the inside, (1 and 2 in the figure) using a
correct filler (filler material depends upon the material in the dished end and weld
plate).
4. Check how the weld plate is fitted. It shall be flush with the inside of the lower
dished end.
5. Tack weld the weld plate at two more points from the inside (3 and 4 in the figure).
6. Turn over the dished end and place
it on a flat bench. Seal it between
the bench and dished end with the
aid of tape or similar. Fill the dished
end with argon gas. It will normally
take about 3 or 4 minutes to replace
the air with the inert argon gas.
7. Tack weld the weld plate from the
outside. The sequence 5-16 as
shown in the figure shall be followed
(diagonal welding).
NOTE!
Rev B, October 2015
Use as little heat as possible
and weld in small steps with
low current. Allow the dished
end and the weld plate to cool
slowly on completion of each step of welding. No cooling
medium other than air shall be used.

4.2
Mounting of bearing unit and impeller
The bearing materials used are either Tungsten Carbide (TC) or Silicon Carbide (SiC), which are
very hard but brittle materials. It is therefore important that the bearing is protected from
physical damage. It is also of the utmost importance that the bearing surfaces are kept free
from particles to avoid damage or disturbances of the bearing function during operation.
WARNING!
Ensure the impeller and vessel are clean. Do also ensure the
vessel has been cooled, depressurised and ventilated from any
possible gases, and that processed media are not, and cannot
be, allowed to enter the vessel during maintenance work.
CAUTION!
Before the bearing unit and the impeller are to be mounted,
the vessel, pipes and other installed parts must be thoroughly
cleaned from dirt and in particular loose metal particles (can
occur in new vessels). Wetted Sterimixer® components can
otherwise be permanently damaged.
4.2.1
Mounting of bearing unit
Carefully fit the bearing unit together
with the PTFE washer to the weld
plate and tighten to a proper torque
listed below. Make sure that the PTFE
washer has not been incorrectly
trapped during this operation.
NOTE!

Mounting of impeller
Before mounting the impeller, be sure of that the drive unit is NOT mounted to the vessel.
The impeller is to be mounted before the drive unit, thus avoiding any damage caused by
crushing, and making sure that the bearing is not damaged by the magnetic charges arising
from the drive unit magnets.
Carefully position the impeller onto the bearing unit and spin by hand to ensure that the
impeller runs freely.
WARNING!
The Sterimixer® impeller includes strong magnets thus
personnel equipped with pacemaker shall not handle these
components.
CAUTION!

Mounting and dismounting of drive unit
A SMO or SMA drive unit consists of a motor (either an AC, MOTEC, DC or Air driven), gearbox,
flange and rotor (some differences occurs depending on type of drive and size). An SMMS
drive unit consists of a motor (AC), flange and rotor.
4.4.1
Mounting of drive unit
There is two different ways of attaching the drive unit to the flange of the vessel, depending
on Sterimixer® size, by a bayonet coupling or by a threaded joint.
Ensure the magnetic rotor is not damaged and properly aligned preventing physical contact
with the weld plate upon installation and operation.
Be certain that you can handle the weight of the drive unit. For an SMO or SMA low shear
mixer, it is often best to grip the gearbox in order to balance the weight of the drive unit and
to minimize the risk of damage caused by crushing when dismounting. For SMMS medium
shear mixers, the motor must be gripped. Use appropriate lifting device for the larger models,
SM 120 and larger.

Power Installation
The motor applied to the Sterimixer® could be either an AC, MOTEC, DC or Air driven type.
Any electrical connections shall be carried out by an authorised electrician in accordance with
applicable regulations, standards and directives.
Never use the Sterimixer (drive unit) without a frequency converter.
If a control box is used, the drive unit is connected to the control box, which in turn is
connected to the external power supply.
The Sterimixer comes standard with 4-pole AC motors (except the 60/75).
Models 60/75 (2-pole), 85/100, 85/140, 120/150 are fitted with a i = 5:1 gearbox.
Models 120/190, 120H/220, 210/275, 210/350 are fitted with a i = 7.5:1 gearbox.
Models SMMS 85, 120 do not have a gearbox and are directly coupled to the motor.
The actual speed varies with the properties of the application. To measure the real impeller
speed it is recommended to use a IMS (Impeller Monitor Sensor, see 5.4.3).
The theoretical rotational speed at different frequencies and number of poles can be listed as:
Impeller speed -  - (rev/min, rpm)

upon delivery when applicable. Technical information for the motor (drive unit) and the
control box is found within the documentation enclosed with the equipment.
Compressed air driven motor: The air intake to the control box is to be dry, free from particles
(<5µm), and the pressure should be between 6 and 7 bar.
The total length of the air supply hoses from the control box to the motor is not to exceed 10
meters (6 mm inner diameter for SM 60/75 - 85/140 and 10 mm inner diameter for SM
120/150 - 120/190). The oil mist lubricator for the compressed air is located in the control box.

to a low speed (max 50 rpm).
4. For AC applications – The
Sterimixer® starts at low speed.
5. Visually check the direction of
rotation for the impeller, which
should be clockwise when looking
from above. If the Sterimixer
rotates counter clockwise, refer to
section 8 `Troubleshooting´.
6. Stop the Sterimixer® immediately
after completed verification.
WARNING!
Dry operation of the Sterimixer® will damage the bearings.

4.6.2
Calibration of the Sterimixer®
The most important parameters in maintaining proper operation and thereby a long
operational life for the Sterimixer® are pre-set on delivery. The pre-set parameters include
acceleration time, deceleration time, max speed, and min speed.
Acceleration time and max speed will depend very much upon the application. Max speed
must not be set too low, as a cleaning process usually requires a relatively high speed
(approximately 300 rpm) to achieve best performance. The max speed shall not exceed the
specified max speed for each Sterimixer® size, refer to section 5 `Technical data´.
For verification of the speed of the Sterimixer®, use a hand tachometer and the recess
provided on the gearbox shaft.
WARNING!
Rev B, October 2015
Dry operation of the Sterimixer® will damage the bearings.

Parts in contact with the product - internal parts
The impeller, bearing, and the upper part of the weld plate are all parts that come into contact
with the processed product and therefore have a high surface quality in order to fulfil aseptic
requirements.
CAUTION!
5.3.1
The Sterimixer® is a product manufactured with precision
having high demands on surface finish and tolerances. The
product shall therefore to be handled with care to prevent
damage.
!
Impeller
The impeller is the heart of the Sterimixer®. The low shear SMA/SMO impellers generate in
comparison to other mixers such as propellers and the Rushton turbine, a minimum of shear
forces during operation, and thereby a low risk of damage to sensitive products. Alternatively,
the medium shear SMMS is best suited for for incorporation of light or hydrophobic solids into
solution.
The drive is transmitted to the impeller through a magnetic coupling, thus avoiding the
problems presented by through-going shafts.
WARNING!
The Sterimixer® impeller includes strong magnets thus
personnel equipped with pacemaker shall not handle these
components.
The unique Sterimixer® design allows cleaning and sterilisation in place (CIP/SIP), without the
need for disassembly of the unit. The especially designed flow channels and wings in the
impeller provide a continuous flow of fluid through the impeller during rotation. This fluid flow
ensures an effective cleaning of the inside of the impeller including the bearings. For more
information on cleaning and sterilisation of the Sterimixer®, refer to section 6 `Operation´.
5.3.2
Bearing Unit
The standard bearing material used for bearings is Tungsten Carbide (TC) having Silicon
Carbide (SiC) as an option. As both materials are by nature brittle it is important keeping the
bearing protected from accidentally being hit. It is also vital that the bearing surfaces are kept
free from particles to avoid damage or disturbances in the bearing function.
The male bearing and the female bearing must be of the same material, TC or SiC. Do also
ensure both male and female bearings are replaced upon refurbishment of the impeller.

5.3.3
Weld Plate
After the weld plate has been welded into the vessel it becomes an integral part of the vessel,
allowing fitment of the bearing and drive unit.
The outside of the weld plate has a threaded joint or bayonet coupling for the attachment of
the drive unit. The threaded joint will differ depending upon the size of the mounting flange.
The function, however, is the same allowing the drive unit to be easily mounted and
dismounted.
5.4
External parts
5.4.1
Drive Unit
The drive unit consists of a drive (AC; MOTEC; DC; Air) together with the gearbox, flange and
drive rotor. On Sterimixer® 120/150 and 120/190 there are also a drive plate as an interface
between the gearbox and the weld plate. The drive plate can be ordered separately. For
Sterimixer SMMS, there is no gearbox and the motor is directly coupled to the drive rotor.
WARNING!
The Sterimixer® magnetic rotor includes strong magnets thus
personnel equipped with pacemaker shall not handle these
components.

Impeller monitor (optional)
5.4.3.1
General description
51
The Impeller Monitor unit is a system that is able to detect and present the impeller speed.
Depending upon the specific application, the Impeller Monitor can be used in two ways. It can
either be used to detect that the impeller of the Sterimixer® is in rotation, or supply a signal
for measurement of the actual impeller speed.
The operation of the Impeller Monitor is based upon the principle that the impeller contains a
number of equally spaced magnets arranged in a circle in the hub of the impeller. The Impeller
Monitor detects the rotation of these magnets and generates a pulsed signal with varying
frequency depending upon impeller speed.
The Impeller Monitor consists of:

One magnetic sensor.

One sensor wiring socket.

One sensor holder (shape will differ depending upon mixer size and type of drive).

Two distance sleeves (Optional for Sterimixer® 60/75 DC, 85/100 DC & 85/100 - 140
AC extended drive units).
The Impeller Monitor is available with a display, which shows the actual impeller rotational
speed. As standard, the display is delivered with an analogue output, 4 – 20 mA / 0-10 V.
The impeller monitor fitted to the drive unit.

5.4.3.2
Installation and mounting of Impeller Monitor
1. Fasten the holder onto the flange. Do note that there are specific instructions below
for each size and model of the Sterimixer®.
2. Mount the drive unit to the vessel. Do not install the sensor until the drive unit is
installed as the sensor can be accidentally damaged due to rough handling.
3. Screw the magnetic sensor into the holder and through the lock nut as per figure
below. Tighten the sensor until it touches the vessel.
4. Loosen the sensor one or two turns, having no longer contact with the vessel.
5. Lock the sensor in place with the nut. As the holder is threaded, a single nut is enough
to lock the sensor in position.
6. Connect the electrical socket to the sensor.
5.4.3.3
Sensor holder 60/75
The sensor holder for Sterimixer® 60/75 DC is installed on the lower part of the flange, as
shown in the three figures below. The holder is fixed to the flange with two of the screws that

Operation
CAUTION!
The Sterimixer® is only to be operated when mounted in a
vessel, thus avoiding impact damage and loose objects from
becoming entangled in the rotating parts.
!
Temperature limits:
The permanent magnets in the impeller and drive rotor must not be exposed unless for a short
time to temperatures higher than +225°C.
The motor and gearbox shall not be exposed to temperatures exceeding +40°C.
Chemical limitations:
The impeller and bearing are not to be exposed to strong chemicals. Nominal pH range for TC
bearings is 3 - 11 but SiC bearings are applicable to pH 0 to 14. Contact Steridose for further
assistance.
Operational limits:
For proper function of the
Sterimixer® and the bearings it is
essential to ensure it does not run
dry. For the SMA the following can
be used as a guideline.
During operation of the
Sterimixer® a liquid film of the
processed fluid is generated in
between the male and female

the impeller, providing cooling
and lubrication of the bearings. As
a negative pressure is created on the backside of the impeller wings, the processed liquid will
be transported from the inside of the impeller through the holes to the outside of the impeller.
Rev B, October 2015
62
www.steridose.com
Fluid 200mm above impeller
If the impeller is fully covered by process fluid, there
will be enough to fulfil this. However, when the
impeller starts to rotate, the processed fluid will
centrifuge from the impeller and when the speed is
high enough, the impeller is rotating in a “dry” hole.
As there is no flow of processed fluid through the
impeller, the bearing will lack both lubrication and
cooling and subsequently run dry.
To avoid dry running the speed has to be adjusted in accordance to the level in the tank.
This will depend upon the following:

The diameter of the tank

The shape of the bottom of the tank
 The viscosity, as higher the viscosity is the less is the flow through the impeller.
Due to these parameters it is not possible to give any exact data for the maximum speed.
WARNING!
Dry operation of the Sterimixer® will damage the bearings.
NOTE!
For the SMO and SMMS the function of the flow through of the
impeller is different, but the level above the impeller is as
important as for the SMA.
NOTE!
During SIP there is a risk that the bearing will run dry. Please
find further information in section 6.3, “Guide for sterilizing the
Sterimixer®”.

Guide for operation of the Sterimixer®
The impeller is factory cleaned prior to delivery. However, before it is put into service it must
be cleaned in an appropriate manner i.e. in a dishwasher or high pressure cleaning, as per the
requirements of the application.
The operational parameters are pre-set in the control box. In extreme working conditions,
disconnection of the magnetic coupling can occur, i.e. the motor rotates, but not the impeller.
To avoid any disconnection of the magnetic coupling, the acceleration time and the max rpm
should be adjusted to conform to the specific application.
For a Sterimixer® supplied without a control
box, soft manual start of the motor is required
to prevent the magnetic coupling being
disconnected. A suitable acceleration time up
to the max rpm can be anything from ten
seconds to a couple of minutes depending
upon the application.
CAUTION!
Never insert foreign objects in
the vessel when the mixer is
rotating.
No foreign objects in the vessel!

6.2
Guide for cleaning of SMA style Sterimixers®
The Sterimixer® is designed for optimum performance in cleaning in place (CIP) without any
need for dismounting. The flow channels in the impeller provide a processed fluid flow
through the bearings. In order to achieve this, the impeller should be covered with fluid and
rotated at a certain minimum speed. The flow of the processed fluid through the flow channels
is very much determined by the rotational speed of the impeller.
The result of the cleaning is dependent on many parameters such as temperature, time, and
chemical composition of the cleaning agent, mechanical conditions, speed and the type of
product to be removed. It is therefore recommended that the cleaning cycle is validated
before taken into service.
The cleaning usually consists of several cycles e.g. pre-rinse, cleaning with base and/or acid
cleaning agents, main rinse following acid or base cleaning, and a final rinse.
NOTE!
To achieve the optimal cleaning effect the impeller should be
covered with cleaning agent and be rotating.

Sterimixer® – Installation and Operation Manual
65
Example of CIP Procedure:
1. Drain the vessel from processed media.
2. Close the outlet and fill with cleaning agent having the fluid level above the impeller
with at least 150 - 200 mm.
3. A suitable speed is approximately 300 rpm with filled vessel (depending on the size).
4. Normal cycle time is 5 - 20 minutes.
NOTE!
The exact operational conditions for CIP must be validated for
each individual application.
NOTE!
The above cleaning method does not remove any magnetic
particles. Due to the strong magnets inside the impeller all
magnetic particles will be stuck inside the impeller. To have
these removed, the impeller must be removed and cleaned
separately.
CAUTION!
The impeller must be covered with fluid to avoid damage to the
bearings.
!
WARNING!
Dry operation of the Sterimixer® will damage the bearings.

CIP GUIDELINES FOR SMO AND SMMS STYLE STERIMIXERS
The following document provides general guidelines for CIP procedures for Sterimixers with
SMO or SMMS style impellers.
PRINCIPLE OF OPERATION DURING CIP:
The bearing assembly on the SMO and SMMS impeller heads is exposed. When directing flow
from a spray ball to the impeller head, the bearing surface will get in contact with the CIP fluid.
The openings on top of the SMO and SMMS impeller heads also allow the CIP fluid to hit the
weld-plate under the impeller. In order to hit all surfaces, the impeller head needs to rotate at
low speed during the CIP cycle. Please refer to Figure 12.
Typical mixer speed during the CIP cycle is 100 rpm.

Figure 13. SMMS IMPELLER
Rev B, October 2015
Sterimixer® – Installation and Operation Manual
67
TYPICAL CLEANING PROCEDURE FOR SMO AND SMMS STYLE IMPELLERS:
The cleaning procedure can be divided in two steps:
Step 1:CIP solution cleaning
Start CIP solution flow through the sprayball at the recommended flow rate. Open the tank
outlet valve completely to allow full drainage. Operate mixer at low speed (around 50-100
rpm).
Avoid running the mixer at high speed. This may cause the bearing to run dry.
Ensure that the sprayball flow is hitting the impeller head. Typically, coverage test with
riboflavin (usually performed during FAT) will provide evidence that the impeller head is fully
wetted by the cleaning solution.
The duration of the cycle depends on the application and requires to be validated by swabbing
vessel and mixer surfaces.
Step 2: WFI flushing
Repeat step 1 using WFI through the sprayball.
Guide for sterilising the Sterimixer®
6.3
The Sterimixer® is designed for optimum performance in sterilisation in place (SIP) without any
need for dismounting. The selection of method from those listed below depends on the
individual conditions.
NOTE!
The permanent magnets in the impeller and the rotor are heat
stable up to +225°C. Never expose these parts to higher
temperatures. The drive unit and gearbox shall not be exposed
to ambient temperatures above +40°C.
A certain delay in the rise of temperature between the inside of the impeller and the vessel is
caused by the mass of the impeller head. This delay is influenced by:

Sterimixer® size:
The larger the Sterimixer® is, the longer the delay.

Sterilisation method:
Steam sterilisation gives the shortest delay.
Hot air sterilisation gives the longest delay.
When evaluating sterilisation temperature you should focus on the area inside the impeller. A
thermal element should be used if the system is sterilised in a hot air oven or autoclave. For
applications with SIP/SHW where the impeller rotates, the validation should be carried out by
biological tests.
CAUTION!
The impeller must be covered with fluid to avoid damage to the
bearings.
WARNING!
Dry operation of the Sterimixer® will damage the bearings.

6.3.1
Steam Sterilisation in Place (SIP)
The vessel with the impeller and the mounted drive unit is steam sterilised.
Example of SIP procedure:

To remove any condensation inside the impeller during sterilisation, rotate the
Sterimixer® at a low speed i.e. 50 rpm a few seconds, approx. every five minutes. NB!
This is a critical phase for dry running.

When the sterilisation temperature in the vessel has been achieved, the rotation of
the Sterimixer® shall be stopped.
WARNING!
6.3.2
Dry operation of the Sterimixer® will damage the bearings.
!
Super Heated Water Sterilisation in Place (SHW)
The vessel and the mounted drive unit are sterilised with super heated water.
Example of SHW procedure:

The vessel is filled with WFI (Water For Injection) to a suitable level.

During heating, sterilisation and cooling the Sterimixer® should rotate.

Vortexes (suction whirlpools) must not arise. The water level and speed controls this.

During the emptying phase the Sterimixer® must not rotate.
CAUTION!
The impeller must be covered with fluid to avoid damage to the
bearings.
!
WARNING!
Dry operation of the Sterimixer® will damage the bearings.
!
6.3.3
Sterilisation in Autoclave or Hot Air Oven
Dismount the drive unit as per section 4.4.2 “Dismounting of the drive unit”.
CAUTION!
The vessel and the impeller (without the drive unit) must be
sterilised in an upright position in an autoclave or hot air oven
to prevent the impeller sliding off the bearing. To prevent this,
a magnetic drive dummy can be installed to avoid any risk of
damage and hold the impeller in place.
!
Example of autoclave procedure:

Dismount the drive unit.

Install the eventual magnetic drive dummy.

At least one pre-vacuum period must be used to eliminate air pockets on the inside
of the impeller.

The vessel, with the impeller in place, is sterilised at a maximum temperature of
+140°C in the autoclave.
Example of hot air oven procedure:

Safety instructions
General:
By design, Sterimixer® bearings are sliding rotary motion devices. For
the proper function, the bearings are depending upon the presence
of cooling and lubrication of the processed media to limit frictional
heat generation.
Poor lubrication and cooling of the bearings will cause excessive temperatures. To avoid
excessive temperatures following conditions must not happen:

The Sterimixer® operates without any process fluid in the vessel.

The Sterimixer® operates with a too low level of process fluid (refer to section 6,
“Operation” for guidance).

The Sterimixer® operates at too high of a speed.

The Sterimixer® operates with a fluid having too high viscosity reducing the flow
through the bearings.
Chemical compatibility: To prevent hazardous reaction between processed fluid and
materials of construction the materials of construction shall be
ensured to be suitable for the application. The Sterimixer® involves
different materials of construction being specified in the technical
documentation.

there will be a risk of chemical incompatibility in between the processed fluid and
the materials of construction creating a possible hazard. Each and every application
shall be handled individually to ensure the safety conditions are maintained.

If the Sterimixer® is subjected to poor lubrication this will create excessive wear and
heat and subsequently premature failure.

If the Sterimixer® is exposed to rough handling permanent damages can occur. It is
therefore essential that personnel involved receive the specified education above.

If the Sterimixer® is incorrectly installed conditions could very likely be similar to
poor lubrication creating excessive wear and heat and subsequently premature
failure. It is therefore important that the operator has received the specified
education above.

If the Sterimixer® is operated beyond its operating limits severe damage might occur
subsequently creating a failure. It is essential that the operator has received the
specified education above together with the full understanding of the Sterimixer®
