1 General
The operating instructions apply for the Watson-Marlow MasoSine Pump :
SPS 600
The operating instructions must be read before installing the pump. Please observe the safety instructions and the safety regulations.
2 Purpose
The purpose of your pump is defined exactly in the delivery note. The ATEX certification becomes null and void following any changes
to the purpose, including changes to components and materials. This is why you should always consult the manufacturer first!
3 Functioning principle
The functioning principle of the Watson-Marlow MasoSine is ingeniously simple. The pump consists of modular components. Because
of the sinusoidal form of the rotor, a chamber through which the product to be pumped is „pushed through“ or displaced is created four
times per revolution when running through the stator space.
As soon as a chamber closes, the opposite chamber opens by the same fraction of a millimeter as the closing chamber is contracted.
A suction and pressure characteristic of the pump free of pulsation results. The scraper prevents the pressure compensation of the
pressure to the suction side. At the same time the scraper undertakes the important function of forced lubrication of the pump bearings,
or when the pump is cleaned the intensive purging of the bearing or of the seal.
4 Safety instructions

The operating instructions must be kept constantly at the place of use of the machine. The generally valid as well as the local
regulations for accident prevention and environmental protection shall be provided and observed in addition to the operating
instructions. All safety and danger warnings on the machine shall be kept in legible condition.
4.8 Dangers when handling the machine
The Watson-Marlow MasoSine Pump is built according to the state of the art and the recognized safety engineering rules.
Nevertheless danger to life and limb of the user or third persons or impairments to the machine or to other assets can arise in its use.
The machine must be used only:
for the intended use delivery note
in perfect safety engineering condition.
Faults which can impair safety must be rectified immediately.
4.9 Safety measures in normal operation
Operate the machine only if all protective devices are fully functioning.
Before switching the machine on make sure that no one can be endangered by the starting machine.
At least once per shift inspect the machine for “externally detectable damage” and for functioning of the safety devices.
4.10 Protective devices
All protective devices must be attached correctly and functioning before every start-up.
Protective devices may be removed only
-after standstill and simultaneous protection against restarting the machine.
On delivery of part components the protective devices must be attached according to regulations by the operator.
If hot or cold machine parts can lead to danger, these must be protected by the operator on site against contact.
4.11 Dangers due to hazardous pumped material
In the case of hazardous pumped material (according to ArbStoffV) the corresponding regulations must be complied with.
4.12 Dangers due to electrical energy

4.15 Constructional changes to the machine
Make no changes, attachments or conversions to the machine without approval of the manufacturer. All conversion measures require a
written confirmation of the Watson-Marlow MasoSine company. Immediately replace machine parts in not perfect condition. Use only
original spare and wearing parts. In the case of parts not obtained from MasoSine it is not guaranteed that they are designed and
manufactured in compliance with load and safety requirements.
4.16 Noise of the machine
The continuous sound pressure level proceeding from the machine is max. 70 dB(A). A higher sound pressure level that causes noise
deafness can arise depending upon the local conditions. In this case protect the operating personnel with corresponding protective
equipment / protective measures.
4.17 Maintenance and repair, troubleshooting
Perform specified adjustment, maintenance and inspection work on time. Inform operating personnel before starting the maintenance
and repair work. Protect all plant parts and operating media connected before and after the machine such as compressed air and
hydraulics and similar against unintentional start-up. In all maintenance, inspection and repair work switch the machine free of voltage
and secure the main switch against unexpected switching back on. Switch off the main switch and withdraw the key.
Attach a warning sign indicating that the switch must not be turned on again. Fasten and secure larger assemblies on
replacement carefully to lifting gear. Check loosened screw connections for firm seating. Use only original spare parts.
After ending the maintenance work check the safety devices for function.
4.18 Cleaning the machine
The bearings that are placed in the bearing housing of the pump wear off continuously which influences the run time. That is why both

5 Safety instructions (ATEX)
Watson-Marlow MasoSine - Pump used in production machinery with explosive mixtures will be equipped accordingly in the factory.
5.1 Safety signs
The following ATEX symbols are only given as an example.
The specific ATEX classification is printed on the nameplate and the certificate of conformance provided with every ATEX pump.
Grounding symbol

Revision 4.4 / January 2019
8
5.2 Pump classification
The pumps are only designed for jobs lasting several days and are therefore assigned to the Device Group II –Application field “dust –
or gas –explosive areas”!
5.3 Zone classification
The Watson-Marlow MasoSine Pumps can be used in explosive areas of the zone 1 / 21. This corresponds to the category 2 G / D.
It is expressly forbidden to use the pump(s) in the zone 0!
5.4 Classification of the ex-atmospheres
A distinction is made between dust and gas explosive atmospheres. In the model code, the atmosphere is abbreviated with G (Gas) and
D (Dust). Watson-Marlow MasoSine Pumps are only designed for the explosive atmospheres G (Gas) and D(Dust)!
5.5 Ignition protection
Our pumps are subject to ignition protection "c" constructive safety according to the standard for "non-electric appliances for use in
explosion-risk areas" EN 13463-5
5.6 Temperature classes
-EX II 2 G c IIB T4
-EX II 2 D c T=120°C
5.7 Limit values for the pump
The limit values for the pump (max. speed, max. pressure, max. temperature) are stated in the delivery note. These limit values must
never be exceeded under any circumstances! This applies in particular when using a frequency converter.
If the pumps are supplied without a drive, the following values apply!
SPS 600
max. Druck *
15 bar
max. Drehzahl *
600 UpM
max. Temperatur (T4) *
60°C
max. Temperatur (T3) *
120°C
Umgebungstemperatur
-12°C bis +40°C
5.8 Grounding the pump
All supplied pumps are equipped with a grounding option.
In particular in ex-areas, the pump must be grounded by fixing a grounding cable to the corresponding position (see diagram).
In addition to the grounding of the pump, the motor also needs to be grounded! If the drive is not grounded, the pump aggregate may
not be operated.
5.9 Material properties
Plastic parts that are fitted inside the pump react more to temperature changes that stainless steel parts. For this reason, the specified
maximum medium temperature (Tm=100°C), for which the pump is designed, may not be exceeded. If the specified temperature is
exceeded, this may cause a linear expansion and may block single components; this in turn could cause the pump to fail or could result
in damage to parts of the pump. Also, excessive temperatures can accelerate the wear of dynamic parts and therefore reduce the
lifespan of the plastic parts.
Corrosion may occur to the Power Frame of the pump if the paintwork is damaged. Corrosion represents a hazard for the use of pumps
in explosive areas (for measures, see Troubleshooting Chap. 21).
5.10 Pressure Conditions
To avoid any over-pressure in the pump as a result of a closed pressure line, a pressure controller must be installed.
Grounding

Revision 4.4 / January 2019

5.11 Maintenance / Repair
The Filling of the pump is only permitted outside the explosion aria. Tools that are used should in compliance with ATEX.
The pump aggregate always needs to be kept clean of dust with a damp cloth to prevent the dust from smouldering.
The rinsing channels in the power frame must always be checked for blockages and if necessary cleaned.
5.12 Cleaning
Caution! No solvent cleaning agents may be used to clean the pump as this could create an uncontrollable explosive atmosphere.
5.13 Medium to be pumped
Chemicals that are combustible below the temperature 120 degrees Celsius and Carbon disulphide must not be pumped.
5.14 Coupling
If the pump is used in an explosion-risk area, the pump must only be coupled to the drive by means of an elastic, positive coupling with
ATEX certification, at least corresponding to the supplied pump. Chains, toothed belts, v-belts or similar equipment which may transmit
radial forces on the bearings should not be used.
5.15 Drive
Any preceding reduction gears and/or control units must have the corresponding ATEX certification, at least corresponding to the
supplied pump. Combustion engines must never be used!
For operation with a frequency converter, this must either be installed outside the ex-zone, or have the same ATEX certification
corresponding to the delivered pump. In any case the converter must have the properties required for operation in ex-zones, for
example, temperature monitoring, speed limitation, etc.
6 Warranty and liability
Basically our “General sales and delivery conditions” apply.
These are available to the operator at the latest since conclusion of the contract.
Warranty and liability claims for personal and material damage are excluded if they are attributable to one or several of the following
causes:
Use of the machine not as intended
Incorrect installation, operation and maintenance of the machine
Operating the machine with defective safety devices or not correctly attached or not functioning safety and protective devices
Non-compliance with the instructions in the operating instructions regarding
transport,
storage,
installation,
start-up,
operation, maintenance and setting of the machine.
Unauthorized constructional changes to the machine
Insufficient monitoring of machine parts subject to wear
Incorrectly performed repairs
Cases of catastrophe due to effect of foreign bodies and acts of God.
Watson-Marlow MasoSine grants no warranty on this documentation as well as no implicit warranties on customary quality and
suitability for a certain application.

MasoSine. Rights reserved to make changes in these operating instructions.
7 Transport instructions
The choice of the means of transport is according to the size of the pump and of the drive. The pump must be suspended correctly for
transport. The crane/forklift truck and the ropes/belts must be sufficiently dimensioned. If the pump is transported with a lift truck or a
forklift truck, it must be noted that the console centre point is not automatically the centre of gravity.

8 Installation
The motor shaft and pump shaft connection
must be protected against contact!
Place the pump on a level ground.
Do not start without the protection against contact!!
The foundation should be dimensioned sufficiently for the weight of the pump.
There should be sufficient space for maintenance work around the pump.
It must be guaranteed that the motor receives an adequate air supply.
If the pump is used in explosion endangered rooms, an Ex protected motor must be used.
The total unit must be protected against static charge.
Align the shaft of the pump with the shaft of the drive.
9 Connection to the piping
Before connection clean the piping and remove foreign bodies.
(e.g. there can still be residues in the pipes due to welding work).
Fit elastic intermediate members (compensators) between pump and fixed piping on the suction
and pressure side. This should prevent vibrations of the pump being transmitted to the piping system.
Forces and torques acting from the piping on the pump connections (e.g. due to distortion, expansion due
to temperatures etc.) must be avoided.
The pressure line should point upwards, so that later residual liquid can always flow back into the pump.
Thus total dry running is avoided. Further it facilitates the later suction process.
The operator has to ensure that an inadmissible pressure rise (above the pressure agreed in the order
and listed in the technical data) is not possible.
The Watson-Marlow MasoSine pumps normally run with such a low resonant frequency that no
corresponding damage is caused. However, particularly when running with converters, certain frequencies
can cause interfering vibrations which must be avoided. It is important during initial commissioning to
ascertain whether such vibrations exist and to define them accordingly, so that the frequency converter
can then be programmed to avoid these frequencies. Similarly, interference from cavitation or rigid lines
must be ruled out.
10 Possible connection positions

11 Changing the connection position
Remove the screws on the bearing block. Turn the housing by an angle of 45° to the left or right.
Tighten the screws again. (with 45 Nm)
However, take care that due to the corresponding arrangement of the pressure line in the pump, a certain
residual amount remains. By this measure you make it easier for the pump to draw in highly viscous products.
However, in the case of horizontally lying pressure connection you must absolutely take care that the pressure
line is run so that the pump is always covered with residual liquid.
In this way total dry running is avoided.
12 Changing the direction of rotation
The suction or the pressure side changes on
changing the direction of rotation of the drive.
Then the gate and the gate guide must
absolutely be turned, since other-wise the pump
cannot bring its full output. If the direction of
rotation is changed, the rotation direction arrows
must be turned correspondingly. Further the
suction or pressure connection must be marked.
The set direction of rotation is stated by an arrow.
The pump can run against the set direction only
for a short time. It cannot build up more than 2
bar pressure if the direction of rotation is wrong.
13 Important: Observe before start-up!
If you have performed cleaning or repair work or make the first start-up, check before start-up that all screws are correctly and
completely tightened.
Observe the corresponding regulations in the case of hazardous pumped material (according to ArbStoffV).
The pump can possibly be contaminated by transport, therefore remove the front cover and clean if necessary before start-up.
Before you start up the pump, convince yourself once again that the gate and the gate guide are in the correct position in relation to the
pressure side (see change of direction of rotation).
The operator must ensure that the pump is installed in an appropriate position with all necessary safety
precautions (sensors, switches, pressure gauges, etc.)!
Let the change of direction of rotation on the drive be made only be trained skilled
personnel. The motor must be protected against unintentional switching on!
C
CA AU UT TI IO ON N
Liquid level
The pump must always be filled with the corresponding
medium before commissioning and during operation,
with the liquid level above the rotor (see diagram).
The filling of the pump should be done outside the
combustible area.
When the pump runs dry, the
temperature limit for the explosive area
is exceeded!
When the nozzle orientation is changed, the motor must be protected against
unintentional switching on!

Revision 4.4 / January 2019
12
The motor must be connected by an expert according to DIN EN 60204.
Make sure before start-up that all valves on the pressure and suction side are open. The pump may not
pump against a closed valve without overpressure valve.
If the pump leaks, end operation as quickly as possible to replace the damaged sealing elements.
The operator must ensure that the pump can work free of cavitation.
Cavitation destroys the pump.
14 Purging
The purging medium must correspond at least to the quality of pure drinking water. Under no circumstances may it be
contaminated by particles (sand or other dirt). This would automatically lead to failure of the seals.
We also recommend using transparent plastic pipes as purging piping.
Purging should be without pressure, i.e. the purging water running out should run out from the purging system without pressure
(thumb test: it must be possible to stop water with the thumb).
To protect the pump against running dry, fill this with some water, possibly through a separate filling valve fitted on the suction or
pressure pipe.
14.1 Static purging device
Before start-up you must fill the purging device (if also ordered) with a suitable purging
liquid (depending upon the product to be pumped).
The purging liquid is filled into the sight glass above through the folding lid until the liquid
level in the sight glass is just below the bent outlet of the pipe.
The pump is rinsed without pressure, e.g. the draining rinsing water should be allowed to
drain out of the system without pressure (thumb test: it must be possible to stop the water
with your thumb).
15 Cleaning
All Watson-Marlow MasoSine Pumps are fully capable of CIP cleaning. Please observe our CIP cleaning regulations.
15.1 Cleaning in own circuit with water, alkali, acid
1. Set control gear to maximum speed (at least 400 rpm).
2. Choke after the pump so that a counterpressure of 3 to 4 bar arises.
3. Should the required cleaning effect not be achieved after this process,
it is necessary to dismantle the pump.
This is done in a few minutes as described in detail in the operating instructions.
Manual cleaning of the pump can be performed after complete dismantling of the pump.
Pay attention to parts sensitive to breakage!!
15.2 Cleaning in the CIP circuit
Liquid level
Fill a suitable
liquid above
1. Purging surge
Open the choke valve and let the Watson-Marlow MasoSine Pumps
run with maximum speed to perform the first rough cleaning.
2. Purging
Set the choke valve so that the pressure side of the pump is at least
3.0 bar higher than the suction side.
Open the open/close valve to guarantee cleaning of the series
connected devices.

15.3 Manual cleaning
Manual cleaning of the pump can be performed after complete dismantling of the pump.
Pay attention to parts sensitive to breakage!!
If the pump is stopped during the process and opened for the purpose of cleaning or checking,
the responsible fitter or electrician must be notified to undertake suitable measures so that the pump
cannot be put into operation (remove fuses, notify electrician).
The pump may also never be put into operation if the housing cover is removed. Should the pump
not yet be connected to the piping system, then reliable care must be taken that the drive machine
cannot be switched on.
Observe the accident prevention regulations!!
15.4 Sterilisation
Sterilization of the pump with standard equipment is possible up to 110°C only in standstill!
In the case of special equipment of the pump or higher temperatures, please always firstly consult the manufacturer!
16 Heating / cooling
Front housing Pump housing
17 Lubrication
The first filling with a corresponding grease lubricant (such as
MOLYDUVAL Soraja C532, DIN 51502, +180°C to –20°C
according to FDA Reg. 21CFR178.3570 or ESSO
multipurpose grease NLGI K2-K30) is made at MASO.
However, the filling amount should be checked regularly and
replenished if necessary. For this purpose unscrew the vent
valve and refill with grease through the lubricating nipple - until
it escapes through the vent bore. If the valve is not
unscrewed before this process, damage to the radial shaft
sealing rings cannot be ruled out! After ending filling simply
screw the vent valve back on!
18 Disposal
Send the used oil or used grease for recycling.
19 Spare parts
Basically repairs should be performed only by factory personnel or by customer service organizations authorized by the factory. If you
perform the work yourself, observe the relevant safety regulations and contact the factory customer service before starting the work,
especially if there are still warranty obligations that can be lost due to not approved interventions.
Only original Watson-Marlow MasoSine spare parts may be used.
You should record changes in the fixtures and fittings, for example another sealing
system or a material change, in writing.
Please provide all information on orders:
- Pump number - Material
- EDP number - Quantity
- Article Ask for our express delivery !
There is a crescent-shaped channel milled into the
housing which is sealed later by a stainless steel
plate. There are connections on two sides through
which the heating or cooling agent flows. Counter-
pressure should not exceed 1 bar. You can dictate
temperature and pumping rate by the heating or
cooling agent.
The cooling/heating agent should enter the
system at the lowest point.
If a heater is to be used at the pump, the

23 Dismantling
Inform electrician!
Disconnect drive unit from mains!
Secure against being accidentally
switched back on!
Undo the 3 cap screws Item 40 and remove the front
bearing housing cover Item 49. Release the tabwasher Item
44.
Undo and remove the locking screw Item 45.
Undo the 3 cap screws Item 51 and remove them.
The front bearing housing Item 52 can then be pulled off the
carrier shaft Item 24 together with the spacer sleeve Item
54.
Remove the flushing pipes from the flush ports. Undo and
remove the lock nut Item 56 from the pump shaft.
Undo and remove the 6 cap nuts Item 4, which hold the
front cover to the pump housing.
Once the cap nuts have been removed, with the help of a
second person you can remove the front cover from the
pump housing, by pulling it off horizontally via the studs
Item 38.
The two front cover pins Item 59 help you to grip the
housing.
Attention:
The front housing is very
heavy!!! (Approx. 60 kg)
The innards of the pump are now in front of you.
I.e., you can see the gate guide, the gate, the shaft
sleeves, the rotor and the two halves of the liner.
When dismantling please ensure that the pump
parts, especially the internal parts and the seals are
not damaged.
You can now pull off the complete front sealing
system from the shaft. Remove the front half of the
liner from the pump housing.
The rotor Item 34, the gate Item 8 and the gate
guide Item 5 are pulled off the pump shaft Item 24,
or the pump housing Item 32 as a single unit.
Here too you should have another
person to help you, one person
should protect the gate guide from
falling and the other the rest.
The remaining parts and the second half of the liner
can also be axially pulled from the shaft or the pump
housing.
If you also want to replace the sealing fixture, or the
lip seals, it might be necessary to unscrew the pump
housing Item 32.
To do this you should use the special assembly tool
from Watson-Marlow MasoSine.
Attention: The pump housing
is very heavy and must not
fall onto the shaft!
ATTENTION!

24 Assembly
The pump is assembled in exactly the reverse order. All parts
of the pump now lie in front of the pump on a soft base.
You see that dismantling was very easy.
If you now start with the installation and assembly of the pump,
please take care that the sealing lips of the lip seals are not
damaged.
If you have the impression that the O-ring or indeed all other O-
rings are damaged, replace these by new parts.
Push the rear half of the liner into the pump housing. The rotor,
gate and gate guide are pushed as pre-assembled unit into the
pump housing. Please note that the bore hole in the front of the
rotor points towards you!
To simplify assembly we suggest that you apply a suitable oil or
grease to the pump shaft. Push on the rotor sleeve coupling
Item 36 so that the larger fixing pin engages in the bore hole of
the rotor. Then push the shaft sleeve Item 74 onto the stop so
that the fixing pin engages in the bore hole of the rotor sleeve
coupling Item 36.
Remove the feather key Item 50 from the shaft.
Screw the lock nut Item 56 on the shaft stump and tighten this
(with a special tool) with approx. 200 Nm, to guarantee axial
clamping of shaft sleeve and rotor. For security tighten all
screws in the lock nut with 2,5 Nm!
Caution! Refit the feather key No. 50 and screw this tight!
Push the second half of the liner up to the stop into the pump
housing.
Push the front cover Item 37 (with sealing holder and sealing
rings), guided by the studs, onto the pump housing. Take care
that the housing gasket is in the correct position. Here as well if
you think that the gasket is damaged, replace it!
Screw the 6 cap nuts onto the studs and tighten these
uniformly and firmly, so that the front cover is connected firmly
with the pump housing.
Then push on the front bearing housing. Take care that the
feather key screwed firmly in the shaft sits in the slot of the
spacer sleeve provided for it!
Tighten the 3 Allen screws, fit the front cover and tighten this
firmly.
