2Safety
Comply with the general safety instructions listed in the safety section as well
as with the special safety instructions listed under the other main sections. All
legal and corporate safety instructions have to be obeyed.
2.1 Safety symbols in this operating manual
Please comply not only with the general safety instructions listed below, but
also with specific safety instructions mentioned in the following chapters.
Non respect of the safety instructions marked with the following signs
represents danger to people:
Danger symbol High voltage symbol
!
Safety symbol according to
DIN 4844 – W9
Safety symbol according to
DIN 4844 – W8
Non compliance with the safety instructions marked with the following sign:
Warning
represents a risk of damage to the micro annular gear pump.
Operating instructions machined directly on the pump such as the indication of
liquid input and output should be followed and kept in a clearly readable
condition.
2.2 Staff qualification and training
The staff operating, servicing, inspecting and assembling the pumps must
evidence the appropriate qualification for these works. Areas of responsibility
and competence as well as monitoring of the staff must be precisely regulated
by the decision maker. If the personnel do not have the necessary knowledge,
they must be trained and instructed accordingly. If necessary, this can be
implemented by the supplier or the manufacturer on behalf of the operator.
Furthermore, the operator in charge must ensure that the content of the
present manual has been fully understood by the personnel.
2.3 Safety-conscious work
The safety instructions listed in this operating manual, the applicable national
regulations for accident prevents and all internal working, operating and safety
regulations of the operator must be complied with.

2 Safety Operation manual mzr-7208, mzr-7208X1
Last update: August 2019 Technical data subject to change without prior notice!.11
2.4 Safety instructions for the operator
The surface temperature of the motor under full load may exceed 60°C. If
needed, this surface should be protected on site against contact in order to
avoid skin burns.
The drive should be protected against dust, water vapor condensation,
humidity, splash water, aggressive gases and liquids. Please provide for
adequate air ventilation and thus cooling of the motor.
The micro annular gear pumps mzr-2905, mzr-4605 and mzr-7205 must not be
used in areas exposed to explosion risks or in the proximity of inflammable
gases and vapors.
Possible leaks of dangerous liquids (for example from the shaft sealing) should
be guided away in a way not to represent any danger for the personnel and the
environment. The pump should be regularly checked for possible leakage. All
legal requirements in this matter should be followed.
The existing protections against contact for the moving parts of the pump (such
as for example the coupling) must not be removed during operation.
Take care that all risks resulting from the electric energy are excluded. (For
details please refer to the instructions provided by the authorities in charge or
your power supplier.)
Warning Please insure, that the totality of the liquid supply accessories such as tubes,
hoses, filters etc. are free from dust or dirt particles. Impurities such as metal,
plastic or glass particles may impair or damage the pump leading to its failure.
Warning Please, operate the pump with a filter featuring 10 µm or smaller pores. It will
protect the pump.
2.5 Safety instructions for maintenance, check and assembly of the pump
As a rule all maintenance work on the device should be performed when the
device is at a standstill. The shutdown procedure described in this manual must
be followed. Pumps delivering liquids hazardous to health must be
decontaminated. Immediately after the work had been completed all safety
equipment and protection measures should be applied.
Before starting the operation, please take into notice the instructions listed in
the chapter 6.
Warning Should a malfunction of the pump occur, do not dismantle the pump on your
own but contact one of HNP Mikrosysteme's service staff for professional
assistance.
2.6 Unauthorized pump conversions and spare part manufacture
Conversions or modification to the device are only permitted with prior consent
of the manufacturer. Original spare parts and accessories authorized by the

2 Safety Operation manual mzr-7208, mzr-7208X1
12 Technical data subject to change without prior notice! Last update: August 2019
manufacturer ensure safety. The use of other parts will annul the liability of the
pump manufacturer for any resulting consequences.
2.7 Improper modes of operation
The safety of operation of the delivered device can only be insured by correct
use, as described in chapter 1. The limit values given in this manual must not be
exceeded in any case.
2.8 General safety instructions
Please observe the following safety instructions
!
The pump may operate at high pressures. For this reason please use only the
delivered accessories and ensure that the employed fittings and tubing have
been prescribed and approved for these pressures.
!
In order to decrease the pressure, provide the system with a pressure control
valve directing the excess liquid to the storage tank or back to the suction side.
In the case of blockage of the pressure side the operating pressure can
multiply, this can lead to the damage of downstream components.
!
At a standstill, the liquid may flow through the pump in the direction of the
falling pressure. In order to avoid this unwanted movement, please integrate
non-return valves (see accessories).
!
Protect the micro annular gear pump and the electric drive against strokes and
shocks.
!
Under normal working conditions the shaft sealing rings integrated in the
pump prevent the liquid from leaking out of the device. The micro annular
gear pumps are "technically leak-proof" however not "hermetically sealed"
which means it may occur that gases or liquids enter to or escape from the
pump.
The allowed operating parameters of the drive should not be exceeded. In
particular an incorrect polarity setting of the supply voltage may lead to
damage of the control unit.
Warning Please insure, that the totality of the liquid supply accessories such as tubes,
hoses, filters etc. are free from dust or dirt particles. Impurities such as metal,
plastic or glass particles may impair or damage the pump leading to its failure.
Warning Please operate the pump with a filter featuring 10 µm or smaller pores. It will
protect the pump.

3 Transport and intermediate storage Operation manual mzr-7208, mzr-7208X1
Last update: August 2019 Technical data subject to change without prior notice!.13
3Transport and intermediate storage
3.1 Shipment of the pumps and protection measures
The pumps leaving the factory are secured against corrosion and shocks. The
inlets and outlets of the pumps are protected with plastic plugs in order to
prevent any foreign bodies from penetrating into the device.
3.2 Transport
In order to avoid any damage related to transport, the package must be
protected against shocks. HNP Mikrosysteme guarantees, that all goods leave
the factory in the best condition. Any noticed damage should be reported to
the concerned forwarding agent, authorized dealer or to HNP Mikrosysteme, as
manufacturer.
3.3 Intermediate storage
Following points concerning pump storage should be observed:
−Necessary conservation procedure (see also chapter 8.4.1)
−The protective plugs must be left screwed in
−The pump should not be stored in humid places
−For storage temperature - refer to chapter 1.3 of the present manual

4.1 Operating principle of the micro annular gear pump
Micro annular gear pumps are positive displacement pumps. They contain two
rotors, bearing slightly eccentrically to each other; an externally toothed
internal rotor and an annular, internally toothed external rotor (see figure 3).
Due to their cycloid indenting, the rotors remain interlocked at any time,
forming during rotation a system of several sealed pumping chambers. As the
rotors revolve around their offset axis, the pumping chambers increase on the
induction (suction) side and simultaneously decrease on the delivery side of the
pump (see figure 4). A homogenous flow is generated between the kidney-like
inlet and outlet.

figure 4 Operating principle of the micro annular gear pump
In the case of rotary displacement pumps, the delivered amount of liquid may
be easily calculated form the displacement volume Vgof the pump and the
number of revolutions of the rotor n. Displacement volume stands for the
volume of liquid that is moved within one revolution of the rotor. This
relationship is illustrated by the following formula:
nVQ g
Vol ⋅⋅=
η
The volumetric efficiency
η
Vol shows the relationship between the actual and
the theoretical flow rate. The existing differences result from internal
movement of the liquid during the operation.
