Machine description
PRINCIPLE OF OPERATION
The dosing pumps are reciprocating displacement pumps with a controlled volume. The reciprocating
motion determines a sinusoidal supply of the flow rate, therefore, the pumped product flow is not
continuous but pulsating. The flow rate or volume of the pump is controlled by varying the diaphragm
stroke. The reciprocating motion of the dosing pump diaphragm determines the flow rate thanks to the
directional valves located at the pump head's inlet and outlet.
The fluid is pumped in the following phases:
>
During the suction phase, the valve located at discharge closes (sealing the leak) and the valve at
suction opens. The fluid enters the pump head chamber.
,>
During the compression phase, the valve located at the suction side closes and the valve at the
discharge side opens. The fluid exits the pump head and enters the discharge pipe.
:
The flow rate value depends on the following parameters:
Number of strokes completed by the diaphragm per minute (depends on the chosen pump model).
Diaphragm stroke and displacement.
Identification plate

Lifting and handling
Having to lift the packaging, it is essential for the operator to assess the container features, the route to
be travelled or assess the need for other operators to transport the load better.
When lifting the package, even if the weight is light, it is best to use trolleys with a capacity that
exceeds the declared pump weight, including the packaging material.
Personnel in charge of handling the load must wear protective gloves and accident-prevention
shoes.
Material storage
If the pump remains decommissioned for long periods of time, especially before commissioning, storing
the material inside its packaging is recommended in order to avoid oxidation of internal components.
The equipment must be stored in a dry, ventilated environment, away from heat sources and at a
temperature ranging between + °C and +40°C.
Handling for installation
The manual contains all the necessary information for installing the dosing pump, taking into account all
safety aspects.
Before handling the pump, check:
•
The efficiency of the lifting means and their capacity.
•
During lifting or moving of the pump, it is necessary to take all possible care in order to avoid
dangerous movements that may cause personal injuries or damage to property.
PUMP INSTALLATION
Optimal operating conditions
• Should the pump be installed outdoors, an adequate protective shelter is essential to avoid exposure
to sunlight or rain.
• If the pump operates indoors, an average level of lighting is important for the safety of people and to
guarantee the quality of work and the correct perception of the symbols and markings.
Pump location
Provide sufficient space (minimum operating areas) to easily inspect and calibrate the pump or
disassemble the hydraulic part (valves and pump head).
• The pump must be placed above a sturdy base (metal, cement,
etc.), stable and properly levelled, avoiding axis tensions.
• Ensure that the piping along the path does not create choking and
especially tension on the axis of the valves, caused by a
misalignment.

PUMP CONNECTION TO PLANT PIPING
Removal of guards
Before installing the pump, remove the protective caps, located on the
suction and delivery inlets of the valves.
Should the pump be decommissioned for a long period of time, before
installing it, we recommend you check that the pump head screws have not
loosened. For increased safety, we recommend disassembling the pump
head to thoroughly ensure that the diaphragm has not be subjected to
alterations of any kind and, if necessary, replace it in order to prevent
serious damage to people and things.
Installation of supplied accessories
Only for the Plastic pump head version (+), the following accessories are supplied.
- END FILTERS - FLEXIBLE PIPING (suction side PVC- Cristal, discharge side PE-Polyethylene)
- INJECTION VALVE.
For different materials (STAINLESS STEEL - PVDF) one must agree upon the supply at the time of the
order.
Suction pipe connection
Suggestions that the installer must follow for proper installation are listed.
• Before connecting the piping to the pump attachments, clean the pipe to eliminate any foreign
bodies, welding beads, gasket scraps, etc.
• If flexible piping is not used, one must consider that the suction piping length must be reduced to a
minimum and be linear, using wide radius curves.
• Avoid reverse slopes to help evacuate any air bubbles, make sure that there is a perfect seal in the
piping, especially in suction, to avoid that the pump disengages.
• The suction piping and fittings must be sized to a nominal diameter immediately above that of the
pump valve.
• Maximum fluid speed, in piping, 1) $) 7( 5 @1 for fluids contained within a viscosity
range up to 100 mPa - (cPs).
• The piping must be properly supported so that the weight does not fall on the pump head and the

Discharge pipe connection
The proper realisation of the path and fixing of the discharge pipe is particularly important for proper
pump operation.
In this regard, we list suggestions which the installer must follow to efficiently realise the plant.
• The piping path must be as linear as possible and be independently supported, ensuring that
expansion due to heat sources does not occur on the pump's head.
• We recommend always providing one or more "T fittings" at the discharge side that can be used to
install pressure gauges, safety relief valves, pulsation dampeners.
• Always provide a safety relief valve and a bleed valve on the discharge circuit in order to protect
the plant, facilitate maintenance and the start-up of the pump.

The control of the fluid dynamics is essential to
guarantee efficiency and use of the process
system.
Not controlling the moving fluids may result in the
dosing system, including the pumps and any
valves, flowmeters, instruments or other equipment
installed on the line, being physically destroyed.
The correct choice of the accessories and their
sizing, ensures the efficiency and life-span of the
system.
Each dosing pump can be fitted with accessories to
improve its operation and accuracy.
The benefits obtained from a correct installation and an accurate control are:
- Increase of efficiency and life-span of the pump
- Reduction of interventions and maintenance costs
9
The dosing pumps have the pulsating flow rate characteristic, as each pumping cycle provides a
suction and a pressing phase. Various benefits are obtained by installing a lung:
- Pump protection against pressure peaks;
- Elimination of vibrations along the length of the discharge pipe;
- A flow rate with a smoother flow useful for the process.
With consequent benefit on the duration of the pump's life-span.
9 ,,
Instrument for measuring any pressure higher than that of the atmosphere used for liquids and gas
and installed on a shunt on the discharge pipe of the dosing pumps. It is necessary to set the safety
relief valve's pressure value, which enables the user to determine the effective working pressure of the
pump.
Constant pressure monitoring and a flow rate check are used to verify the proper operation of the
pump.
9 &++
The safety relief valves are used to protect the pump and the plant from possible damage caused by
overpressure deriving from defective accessories or obstructions in the plant's piping, caused by
sediments or the accidental closing of a shut-off valve. The safety relief valve on the discharge pipe
must be installed immediately after the pump's coupling and before the shut-off valve.

Sampling or draining is carried out by mounting the shut-off valve in a shunt on the discharge pipe, which
discharges in the open air. It is mainly used to drain the discharge pipe from the dosed fluid when
performing plant maintenance or to take a sample of the liquid for flow rate tests.
9
Accessory with the function of retaining the impurities present in a flowing fluid.
We recommend installing the filter (on the suction piping) in order to prevent the impurities that may be
present in the liquid from being dosed from the piping, which may unable the proper operation of the
valves, thus causing irregular flow or passage obstructions. The size of the filter mesh must be chosen
based on the impurities present. While the filter surface is related to the product flow rate, paying
attention to the fact that the smaller the filter surface and the mesh dimension, the higher the load losses
produced by the filter will be. Do not place the suction piping attachment on the bottom of the tank to
avoid sucking impurities, but ensure that the suction area is at a height of at least 10 cm from the bottom.
9 8:
It is an instrument consisting of a transparent Plexiglas casing with a graduated scale and a float inside to
visually indicate the dosed amount (volumetric flow) for an immediate check of the adjusted dosing
volume. At his/her discretion, the customer may install other types of flowmeters deemed more
appropriate for his/her plant.
9 5ID++
The back pressure valve is required to prevent the spontaneous passage of liquid (siphoning) in
conditions in which the suction tank level is higher than that of discharge.
9 9>++>>,
The shut-off valve is used to shut-down the flow of dosed liquid by closing the pump's discharge line.
The dosing pumps are reciprocating displacement pumps.
Regardless of whether the discharge pipe has been closed, e.g. by closing the discharge pipe or a valve,
the pressure produced by the pump may sometimes exceed the admitted working pressure value of the
plant or of the dosing pump. This may cause the piping to explode with dangerous consequences
especially in the presence of toxic or aggressive substances!
Install safety devices on the system, e.g. safety relief/vent valves in the presence of a shut-off valve in the
discharge pipe!
LUBRICATION
The Model pumps are supplied filled with lithium grease.
The pump does not have any other points to be lubricated, therefore the
quantity of grease inserted is sufficient to guarantee proper lubrication.
In order to verify if the internal components of the pump body are covered
with grease, completely unscrew the adjusting screw.
If needed, add grease according to need.

The installer must provide an adequate electric line cut-out switch upstream of the pump and use cables
with a sufficient section to support the maximum current absorbed by the motor.
Suitable devices must be installed with a delayed release to protect against overheating in case of a
blocked rotor, as prescribed by Standard EN 60079-14.
Connections, commissioning, maintenance, measurements and adjustments of the electric equipment or
of its components must be carried out by qualified ()!"(##"$)$#$()(=$"("#$1 only.
Comply with the relative standards in force to perform work on live parts.
Motor connection
Refer to the instructions in the terminal board before making the motor connections and check that:
•The voltage and frequency of the main power supply correspond to those indicated on the motor plate.
•The earth terminal is connected to the protective conductor.
• =)!N1!$$"$/"!()"$(!!1$1))="!()"$')=#!!;$)='#$(F!
•The vicinity of obstacles does not prevent proper ventilation of the motor and make the maintenance
and inspection operations difficult.
Qualified personnel must make the electrical connection with the utmost caution, with the mains
switched off and in compliance with the safety requirements.
It is essential to connect the pump to an efficient and controlled earth line.

Stroke variation with manual system
Adjustment from 0% to 100% occurs in a turn, which on the graduated
scale corresponds to % of the flow rate.
There are 20 notches on the knob, each corresponding to % of the flow
rate, subdivided into 10 that are long from 0 to 9, and 10 that are short.
Model pumps are not equipped with servo controls.

Check pump fixing on its support.
•
Check that the liquid to be dosed is not solidified or frozen in the piping.
•
Check that all shut-off valves on the suction or discharge circuits are open. If the discharge circuit
is fitted with a back pressure and injection valve, open the bleed valve at the discharge side to
enable pump priming.

•
As soon as the liquid leaks, close the bleed valve (where present).
•
Carry out a visual and auditory check (for dripping or suspicious noises).
•
Check the piping is well supported, does not produce vibrations and, above all, does not exert
tensions on the pump head.
•

at least minutes, this allows the pump to heat, which eliminates motor condensation. Then

Inconveniences upon commissioning

•
The features of the motor's electric power supply do not correspond to those on the plate or the
chosen connection is inadequate.
•
Check that the discharge pressure corresponds to that of the project.
=';!#)"1%;)=#)1"!
•
Incorrect pump flow rate adjustment: adjust the flow rate to the desired value.
•
Insufficient suction due to the excessive length of the piping or to a section that is too small. We
recommend replacing the piping with the necessary section or positioning the pump under the head
and as close as possible to the suction source.
•
The suction piping seal is not perfect (possible air infiltrations).
•
The liquid viscosity is not compatible with the pump version or the filter is clogged.
=';!#)"1#%F)=#)1"!
•
Siphoning phenomena occurs: check that the suction pressure is not higher than that of the
discharge pressure. Install a back pressure valve on the discharge circuit.
=';!#)"1F#!"#%
•
The problem may be due to solid particles coming from the piping or sediments in suspension
which prevent the perfect closure of the pump valves. Good cleaning and the installation of a filter
on the suction piping is recommended.
MAINTENANCE
Maintenance is a combination of all technical and administrative actions, including supervision, aimed at
maintaining or returning a machine to a condition in which it can perform the required function. (ref. UNI
10147)
List of spare parts
For proper, easy identification of spare parts, please refer to the drawings in the section attached to the
pump manual where notes are reported, which identify the components that are most subject to wear and
thus require more frequent maintenance. In their absence, request them from DOSEURO, referring to the
plate located on the pump to identify the model, serial number and year of manufacture.
The inspection and maintenance program depends on the conditions of use of the pump.
Good maintenance allows for the best possible performance, longer working duration and a
constant observance of the safety requirements.
