The right dosing choice

We make fluid
The company
Doseuro is a combination of two
capabilities, the first is a technical
expertise gained from many years of
experience in the chemical dosing
field. The second is a commercial
understanding of the changes in this
field and a sensitivity beyond the
requirements of our customers. These
two factors are supported by a strong
company structure that responses to
our customers demands.
The continuous research and principal
effort directed to the customer
satisfaction are the fundamental
reasons of Doseuro success, which
is widely confirmed by the thousand
worldwide plants working with our
pumps.

The product
What makes Doseuro pumps unique?
Its the competitive price-quality
always aligned with the customer
expectations.
Each of our products speaks for itself.
High reliability is achieved by constant
product development, updating
production techniques, constant
quality control and rigorous testing at
all stages of production.
Every model of dosing pump has been
carefully designed, built and tested to
ensure a long and useful life.
If this alone is not sufficient, then
please go further and ask us about
our prices.

Main features
All Doseuro pumps are fitted as
standard with top quality 4 pole
electric motors that conform to
the UNEL-MEC specifications, and
range from 0.09-4.0 kW at European
standard 3 phase voltages of
230/400V @ 50Hz.
Non standard motors are available
to many alternative specifications,
including different voltages and
frequencies, insulation standards, and
special explosion-proof versions.
The dosing rate is fully adjustable
via a manually controlled eccentric
cam mechanism with spring return,
or positive displacement plunger
according to API standard 675.
Automatic adjustment is available
by means of servo-control motors,
pneumatic control or motor frequency
control, interface PROFIBUS or other
BUS, if required. The very strong
gearbox utilises a worm and wheel
gear reduction system.
Our pumps are complemented by
a wide range of accessories which
include, foot valve/strainers, pressure
relief and loading valves, injection
fittings and pulsation dampers.
Special versions of construction are
available to suit our clients specific
applications.

world to move
A view over the production range
Doseuro chemical dosing pumps
are available in three main versions.
Plunger pumps with packed plungers,

pressure pump heads are available,

if requested. The range also includes

various driving methods, such as
electric motor or electromagnetic
solenoid operation. The company
also manufacturers complete dosing
packages, electric mixers, and fully

automatic plants for the dissolution

and mixing of polyelectrolyte
chemicals.

Spring Return Mechanical Diaphragm

Dosing Pump
Mechanical Diaphragm pumps are
suitable for the applications in which:
- the dosed liquid contains small
amounts of particles in suspension
- the dosed liquid contains toxic
solutions
- a drip proof/air tight application is
required
- high pressures are not required
Each pump is built with a standard
gearbox reduction system and a
vertically mounted B14 shaped electric
motor in compliance with UNEL-MEC
specifications.
Motors power is usually 0,09 Kw with
4 poles: 3-phase 230/400 Volts 50/60
Hz, and single phase 230V/50 Hz or
110V/60 Hz.
As they are motors complying to
UNEL-MEC specifications, there are
many available options with different
voltages, frequencies and insulation
classes, whereas explosion proof
versions are not allowed.
The gearbox is worm wheel type and
helicoidal reduction system with all
bearings supported within a fully
lubricated gearbox.
The mechanism for the variation of
the capacity is spring return based
operated by an eccentric; this makes
the diaphragm move forward (pushing
phase) for all the stroke length, while
the spring in continuous tension causes
the comeback of the diaphragm (suction
phase).
