Revision 4.4 / November 20104
1 General
The operating instructions apply for the Watson-Marlow MasoSine:
EC 25 / EC 40 / EC 60
The operating instructions must be read before installing the pumps. Please observe the safety instructions and the safety
regulations.
2 Purpose
The purpose of your pump is defined exactly in the delivery note. The warranty becomes null and void following any changes to
the purpose, including changes to components and materials.
Always consult the manufacturer before any changes are to be made to the pump, its components or application.
3 Functioning principle
The functioning principle of the Watson-Marlow MasoSine Pump is ingeniously simple. The pump consists of modular
components to allow for easy assembly, disassembly and in-line maintenance, preventing the need to return the pump for
factory repair. The MASO-Sine pump’s exclusive sinusoidal rotor creates four symmetrical pumping chambers that draw product
through the pump. As product is drawn through in a continuous flow, it encounters the scrapergate and is discharged by product
flowing behind it creating a continuos pulse-free laminar flow. The MASO-Sine pump’s large pumping chambers maintain
constant volumetric displacement throughout the entire pumping cycle that eliminates product compression and minimizes
damage to large particles.

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
Grounding symbol
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”!
Revision 4.4 / November 20107
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
For product temperature up to max. 95°C: EX II 2 G c 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 data sheet (see page 4). 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!
EC25 EC40 EC60
max. Pressure * 6 bar 6 bar 6 bar
max. Speed * 600 rpm 600 rpm 600 rpm
max. Temperature *
95°C* 95°C* 95°C*
Ambient temperature -12°C bis +40°C -12°C bis +40°C -12°C bis +40°C
* depending on the rating of the pump (pls. see order confirmation)
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.
Grounding
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=95°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.
Revision 4.4 / November 20108
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 (T4/T=120°C) 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

CAUTION!
Cavitation destroys the pump!
The motor shaft and pump shaft connection

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.
WITHOUT COUPLING GUARD!
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 SINUS 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.
The operator has to ensure that the pump can work free of cavitation!

pcs.) and remove the shaft and bearing housing assembly from the
pump housing. Rotate the bearing housing assembly until the vent is
Due to construction, the pump is able to turn clockwise as well as
counter clockwise. For doing this any conversion or modification is not
necessary.
All you have to do is changing the direction of the gear motor.
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 pump cover and clean if necessary before start-up.
Before you start up the pump, convince yourself once again that the scraper and the guide cartridge are in the correct position in
relation to the pressure side (see change of direction of rotation).
CCAAUUTTIIOONN
The operator must ensure that the pump is installed in an appropriate position with all necessary
safety precautions (sensors, switches, pressure gauges, etc.)!
Liquid level
Revision 4.4 / November 201011
The pump must always be filled with the
corresponding medium before commissioning
and during operation, with the liquid level

CCAAUUTTIIOONN
CCAAUUTTIIOONN CCAAUUTTIIOONN
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 Cleaning
All Watson-Marlow MasoSine Pumps are fully capable of CIP cleaning. Please observe our CIP cleaning regulations.
14.1 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 (44 to 58 psi) 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.
