PUMP DESCRIPTION AND OPERATING PRINCIPLE OF SIDE CHANNEL PUMPS
The MODULAR V pumps are vane pumps, horizontal multistage magnetic drive. Airtight construction, with
internal cartridge full extension, with magnetic drive meets the requirements of work safety, functional safety
and environmental protection. Conceptually they are constituted by a rotor, within which slide radially in four
blade tribological material, placed at the periphery by a said stator ring, which has as peculiarity the fact of
having a cam profile on the inside. This profile determines the possibility on the part of the vanes, which slide
inside this, to isolate a specific portion of liquid, the liquid that comes from the suction duct, and push it towards
the delivery duct, without the possibility of leakage.
The amount of liquid depends substantially isolated by the eccentricity of the same stator, while the absence of
leakage depends on the precision of execution. At the end of the "rooms" pumping, they are placed two discs,
which in addition to the task to confine axially the rotor, serve at the same time by radial Shaft supporting, acting
as plain bearings.
In the above, it adds the feature of the modular design, which allows to couple several pumping stages, up to a
maximum of 6, allowing it to multiply the discharge pressure produced by the pump. The program includes 13
sizes, referred to as VA, VB, VM with a high interchangeability between components that allows a reduction in
costs of spare parts.
Applications
pumps in general, this model is ideal for clean liquids slightly contaminated, no particles that may become
magnetized;
the maximum working pressure of the plant,the temperature suitable and the maximum rotation speed
depends on the type of pump and it is specified in the "TECHNICAL DATA".
Other uses are not permitted because you must comply with the conditions of use in "TECHNICAL DATA": the
use of a pump in a plant or in fluid conditions different from those for which the pump was designed, can lead to
dangerous situations for the user.

OVERALL DIMENSIONS
See specific documentation provided with this manual.
NOISE AND VIBRATION
The pump noise depends primarily on the operating conditions. The operating condition of the pump during the
measurements is: the coupling of the pump with the electric motor on the bench with pumping fluids.
The A-weighted sound pressure level to front and side of the pump is below 85 dB (A).
RADIATION IONISING
The pump does not emit any kind of ionising radiation that could endanger persons.
CHECKS TO PUMP DELIVERY, STORAGE
All M PUMPS pumps are tested before shipment and carefully packed for transport: at the reception of the pump
make sure that the pump has not been damaged during the transport. If there are problems, contact
immediately the carrier and inform M PUMPS about what happened.
So that the pump is preserved over time as best as possibile, we recommend storing it away from the sun, bad
weather and dust, if not immediately installed or used for long periods.
Stoppers closing the input and output connections of the fluid must not be removed until installation. If provided
with electric motor, observe also the motor manufacturer’s storage formality.
The maximum allowable temperature range during storage, preservation and use must be between -15 e +40 °C
with humidity between 10 e 90%.
SHIPPING AND HANDLING
You should carry out a precautionary check of the pump at the receiving to detect and report any damage in the
transport and handling operations. In case of breakages contact immediately M PUMPS .
The precautions to ensure the stability of the pump concern the possible slips and overturning caused by
handling and transport, which must be prevented by setting the pump casing of the pump with ropes to the
vehicle frame.
Pump and motor assembly cannot be moved manually due to its high weight.
To move a pump positioned on a pallet, enlarge as maximum as possible the forks and then operate.
For a stable lifting the pump can be lift as indicated in the figures:
close couple pump without motor
Bare frame pump without motor
close couple pump with motor
Centre of gravity approximately in
the middle
Centre of gravity approximately in

These operations must be performed by a trained staff who is informed of the risk of these proceedings.

Pag. 10/32 Doc. ISM0023 Instruction Manual of series V MODULAR –Rev.02
PROHIBITION
It is forbidden to lift the pump using different lugs from the ones specially designed and
reported, as points of anchorage.
You cannot lift a pump and motor assembly using the eye-bolt of the electric motor
only.
During the lifting the entire surrounding area is considered as a danger zone and must
be cleared by personnel not engaged in those operations.
It is indicated the possibility of transporting and handling the pump using the lugs designed for that use: you
must ensure that chains and shackles are able to withstand the weight of the pump (as shown in "TECHNICAL
DATA").
ASSEMBLY, INSTALLATION, CONNECTIONS, COMMISSIONING AND SETTING
Assembly
Install the pump on a solid foundation as close as possible to the liquid to be pumped, below the level, in a
position to facilitate maintenance and inspection.
Ensure that the pump doesn’t take rough shacks as this may damage the magnets of the internal and external
rotor or the silicon carbide bearings.
Ensure that the heated air from other units does not affect the pump; the air temperature must not exceed
40 °C, for higher temperatures contact your distributor M PUMPS ; ensure also the free circulation of air cooling of
at least ¼ the engine diameter, because either the pump or the motor should be able to dissipate the heat by
natural air convection. Insufficient cooling could lead to high surface temperatures of the bearings seat, poor
lubrication and premature failure of bearings. Useful is the monitoring of the surface bearings’ temperature.
It is always responsibility of the operator to keep low the temperature of the liquid so that not to superheat the
pump: in case of irregular pressure fluctuations and flow drop turn off the pump.
CAUTION
Normally you should mount the pump horizontally. If mounted vertically or inclined,
the pump, or rather the suction flange shall be placed in the lowest point. Leave a
space of at least 50 cm between the pump and any walls or pipes.
When pumping liquid can reach high temperatures: form 60 °C upwards you must
install protections to prevent contact with hot pump parts;
Connect to the ground the entire pump casing to prevent accumulation of static
electricity;
If the pumped liquid can be dangerous to people and environment, the user must take
precautions for a simple and quick block in case of leakage for breakage/ replacement/
pump maintenance.
Connection of the pump to suction and discharge pipes
For a proper assembly aimed at an optimal use of the pump, you must follow these requirements:
pipes must be supported and kept in line regardless of the pump, until its connections, so that not to
impose on it;
links must not be subjected to stresses during the job ;
the maximum permissible forces and moments on flanges shall not exceed those listed in “technical
data”;
inlet pipes should be constructed with as few restrictions as possible in order to have the highest
available NPSH;
the length of pipes , particularly that of the inlet pipe must be minimized;
the pipe must be placed so that it is not possible the formation of air; if this is not possible, it should be
calculated the possibility of bleeding the air from the highest point ;
during suction use full section valves only;
if the suction tube was larger than the suction flange, you will use an eccentric reduction, in order to prevent
formation of air and turbulence;

Doc. ISM0023 Instruction Manual of series V MODULAR –Rev.02
Pag. 11/32
if there is a possibility that the maximum working pressure can be overcome, for example due to excessive
suction pressure, you should take appropriate measures by including a safety valve in the pipe;
Avoid using quick-closing valves, because sudden changes of pressure cause water hammer very dangerous for
the pump and the pipes;
Before installing the pump, make sure the suction line is clean and/or provided with a filter to protect the
impeller and the stationary bearings from damages incurred by slag, or other foreign particles , especially when
you start the installation for the first time.
Electrical connections:
DANGER
The pump is provided with or without electric motor: only qualified personnel
should carry out mechanical connection of the pump to the motor (for the model without
motor) and the electrical connections of the motor to the electrical system. Please read
carefully the instructions of the manufacturer of the motor or the manual before you
complete the installation.
Make sure that the motor doesn’t start during maintenance jobs.
Checks for the proper operation
We recommend installing a pressure gauge on both inlet and outlet pipes to allow the operator to easily control
the proper pump functioning in relation to the required operating point: in case of cavitation or other
malfunctions, there will be obvious pressure fluctuations.
Check the differential pressure of the pump between the suction and discharge connections to verify that it works
in the point of work provided.
Check that the absolute pressure at suction is not so low to cause the cavitation.
CAUTION
The absolute pressure at pump suction (m) must be at least 0,5 to 1 m, the vapour
pressure of the pumped liquid, in order to avoid cavitation.
Cavitation should always be avoided as it is very dangerous for the structure of the pump.
Do not dry run the pump!
Commissioning and operator training
Fully open the inlet valve and fill the pump and suction line;
Ensure there are no obstacles to the free rotation of the pump impeller.
The M PUMPS series V MODULAR are not
reversible so the rotation cannot be reversed.
The proper direction is clockwise.
If you put in front of the pump casing, an arrow
indicates the correct direction of rotation; to reverse
the direction of rotation may cause damages to the
pump.
To control the direction of rotation, give and
immediately remove voltage, then observe the
direction of rotation.
ROTATION SENSE:
Make sure that rotating parts, such as flexible coupling or other related organs, are always protected when the
pump is running.
Operators using the pump must have read this manual in the sections committed to the functioning, use and
maintenance, as well as being qualified to fully understand the features and to be able to identify the problems of
the pump.

Pag. 12/32 Doc. ISM0023 Instruction Manual of series V MODULAR –Rev.02
By carrying out the functions mentioned in the previous section and all controls listed in the register
maintenance, the pump is ready for use.
Self-priming pumps and non self-priming pumps
V MODULAR pumps are self-priming: Make sure the pump is always filled with the pumping liquid to maintain the
self-priming feature. Use a back flow check valve to stop reverse flow when operating with suction lift, dry run
should be avoided.
Coupling of the pump to the motor
If the pump and the motor are coupled respect the following sequences to proceed with the installation:
Fill the two elastic coupling halves on the pump and the motor.
Position the pump on the base plate.
Place the motor, insert thicknesses (about 5mm), under the feet, so that the two shafts (pump and motor) are
coaxial.
Leave a space of 3mm between the two elastic coupling halves, and then block the motor with the provided
screws.
Features and installation of pump and motor assembly
The shafts of the pump and the motor have already been adjusted and aligned as an extension of one another.
For installation of the plant it is necessary to respect the sequence of actions:
The base plate must be affixed to an horizontal plane, using also thickness;
Tighten the nuts of the bolts;
Check the shafts alignment and the motor alignment and repeat these actions if necessary (described in
the paragraph “Alignment of the coupling”).
Alignment of the coupling
Place a straight edge on the coupling.
Insert or remove any thickness necessary to
bring the motor at the correct height, so
that the bottom edge of the ruler is placed
on both halves of the coupling for the entire
length;
Repeat the same check on both sides of the
coupling, at the height of the shaft. Turn
the motor shaft so that the bottom edge of
the straight edge touches both halves of
the coupling for the entire length;
Reinstall the protection.
Alignment tolerances and coupling
The maximum allowed tolerances for the two halves alignment of the coupling, to be verified with the
comparator, are:
TYPE OF COUPLING
OFFSET
ANGLE

INTENDED USE OF THE PUMP. IMPROPER USE. DESCRIPTION OF
FUNCTIONING.PERSONAL PROTECTIVE EQUIPMENT DURING USE.
Intended use of the pump
The magnetic drive pump, thanks to its decoupling between the pump and the motor, never enters into direct
contact with motor parts, providing a friction effect on the impeller of the pump. The pump works correctly if the
parameters specified in the paragraph “TECHNICAL DATA” are followed.
Instructions for proper use reasonably foreseeable
Before starting work you must check that:
All maintenance actions were properly carried out according to the time intervals set by M PUMPS ;
There are no damaged parts of the pump;
All the warning stickers and safety licence plates are present and in good condition and are operating the
emergency stop buttons (check through a test).
CAUTION
Do not dry run the pump!
At the start, immediately check the pressure gauge placed in the discharge: if the
discharge pressure reaches the nominal value quickly, stop the pump and try staring.
Check the pump and piping to make sure that there is no leakage of liquid from the plant.
A noisy pump is a symptom of a malfunction that represent a failure in the short term. A
very low frequency and with a rumbling can indicate the state of cavitation; an excessive
noise of the motor can be caused by a wear of a bearing.
Not permitted use
While maintaining the conditions of use indicated in the paragraph “TECHNICAL DATA”, the ways in which the
pump should not be used are given here. To avoid damaging the pump, it is forbidden to use it in the following
conditions:
PROHIBITION
Start the pump dry: the pump casing must be full of liquid.
Run the pump dry for more than 1 minute;
Mare the pump work with inlet valve and /or outlet closed: the heat generated by the
impeller, by magnetic coupling and bearings will boil the liquid, which will cause pump
cavitation/vibration, the impeller damaging and the bearings collapse;
The pump flow should never be adjusted by the valve located in the suction pipe,
which must be kept fully open, start and or make the pump work if there are losses;
Start the pump if there are losses;
Change working condition of the pump without having consulted the M PUMPS
technical office;
loosen the pump connections while under pressure;
try to clean the pump while it is running;
run the pump in the opposite direction to that shown in the pump casing;
run the pump over nominal temperature and pressure;
pumping liquids containing ferromagnetic particles of any size, or substances that can
attack chemically or erode the inside of the pump;
remove guards and shelters while the pump is running;
act on electrical parts installed without first removing the tension, not to alter the
safety devices installed, do not activate repeatedly the command buttons.
DANGER
It is incorrect any use of the pump other than that mentioned in the paragraph

Pag. 14/32 Doc. ISM0023 Instruction Manual of series V MODULAR –Rev.02
“Instructions for a proper use reasonably foreseeable”.
M PUMPS disclaims any liability damages to things and people related to uses for which the
pump was not specifically designed and constructed.
Also the ways in which certain situations of danger might present as a result of improper use, are prohibited.
RESIDUAL RISKS AND PROTECTION MEASURES TO BE TAKEN
Description of the residual risks that remain
Despite adopted measures incorporated in the pump, the main dangers associated with the use of the pump and
the solutions identified are the followings:
Danger of sketches projection of process fluid that can be corrosive or burning, as a result of improper
installation and sudden ruptures of the pump casing and hydraulic lines;
Danger of cuts to the hands due to the presence of smears on the pump casing;
Explosion of the pump is due to a formation of explosive mixture inside the pump casing as a result of an
improper use.
Protection measures to be taken by the user and instructions
PROHIBITION
It is absolutely forbidden to the user to tamper with safety devices. Before using
the pump check the proper couplings mechanical protection. Any tampering nullifies the
warranty and liability of M PUMPS towards the pump users.
Only maintenance personnel can perform maintenance operation affecting safety devices.
Personal protective equipment to wear
Protection measures that have to be taken during this phase are adopting antacid and antistatic coverall,
chemical-resistant glasses, gloves to protect from mechanical and chemical agents and safety shoes.
Avoid the use of accessories (necklaces, bracelets, etc.) and clothes unshackled; torn or dangling that could get
entangled in parts of the structure.
OPERATIONAL LIMITS, DESCRIPTION OF HAZARDS NOT EXCLUDED FROM THE
SECURITY MEASURES TAKEN
Dangers that have not been reduced/ eliminated with the security measures adopted on the pump can be
reduced/eliminated if operators apply measures on management as a result of having to:
Keep all the safety warnings of and all plaques and labels intact and replace them when necessary,
periodically checking their good condition;
Don’t employ substances which may affect the physical ability or the mental faculty (alcoholic
beverages, medicines, drugs, etc);
Don’t use without permission spare parts not identical to the originals or components not approved by
M PUMPS ;
Don’t perform any modification or structural intervention without the approval of M PUMPS ;
After shocks accidentally suffered by the pump, check the pump integrity and perform a check to
 M PUMPS ;
After a long period of pump detention check the pump integrity and functionality of stakeholders to
wear. If necessary perform the replacement with identical spare parts to the originals.

PERIODIC AND EXTRAORDINARY MAINTENANCE
Proper maintenance and use are essential factors to ensure the functionality and pump lifetime.
Cleaning components and magnet
To clean all surfaces of the couplings and centering surfaces, use possibly methyl alcohol. Use paper towels
instead. Do not use solvents and other corrosive liquids on magnet to avoid damaging it; any dirt can be
removed from the magnets by using gummed paper. Do not hack or put pressure on the magnet during its
handling, it would cause them, damages because of their fragility.
Periodic preventive maintenance
Instructions relating to maintenance activities whose implementation do not require specific skills that can then
be made by users of the pump, are given. They are operations and inspections planned on issues considered
important for technical, operational and security staff, determined on the basis of the knowledge gained from M
PUMPS . If the hydraulic pump is washed with jet in pressure, prevent the entry of water into the terminal of the
motor.
DANGER
Do not throw water on the pump hot components: components can explode in case of
sudden cooling generating projection of metallic material and leakage of hot fluid in
pressure and hazardous to health. Do not give strokes and pressures on the bearings, you
would cause the formation of micro-cracks which can cause serious damages.
