1General Information
Please read the »manual for micro annular gear pump« carefully before initial
operation of the pump. The manuals for motor and control have to be seen as
part of the pump manual. For missing manuals please call your distributor or
HNP Mikrosysteme directly. Manuals are also available to download at
www.hnp-mikrosysteme.de.
In case assistance is needed, please indicate the pump type visible on the
housing.
1.1 Use
The micro annular gear pumps described in this manual are suitable for
continuous delivery and discrete dosage of water, watery solutions, solvents,
methanol, oils, lubricating liquids, paints and varnishes as well as many other
liquids.
!
If you intend to treat any aggressive, poisonous, or radioactive liquids, you
must conform to safety measures as according to the regulations in force. Any
project concerning handling of corrosive liquids should be previously discussed
with the pump manufacturer.
!
The micro annular gear pumps must not be used for invasive medical
applications, in which the liquid having had contact with the pump is re-
introduced to the body.
!
Micro annular gear pumps exclusively are provided for use in the industrial
area. A private use is excluded.
!
The micro annular gear pumps must not be used in aircrafts and spacecrafts or
other vehicles without prior consent of the manufacturer.
!
Data concerning resistance of the pumps to the manipulated liquids have been
elaborated according to the best of HNPM's knowledge. However, operating
parameters varying from one application case to another, no warranty for this
information can be given.
!
Information given in this manual does not release the customer from the
personal obligation to check the integrity, correct choice and suitability of the
pump for the intended use. The use of the micro annular gear pumps should
be conform with technical norms and regulations in force.
If you wish to receive more information than comprised in this manual please
contact directly HNP Mikrosysteme.

1.8 Technical data of the Ex-motor
The micro annular gear pumps mzr-2509 Ex, mzr-2909 Ex, mzr-4609 Ex,
mzr-7209 Ex are equipped with an explosion-proof DC-motor. The parameters
of the motor are described in Table 2. The speed of the motor can be
controlled with the optional motion controller S-HD-KL. One of the motor’s
features is a highly dynamic behavior. For operation it is recommended to use a
power source of 24 V (with a power rating of 5 A).
The motor of the pumps is corresponding to the applicable EC standards. The
confirmations according to EC 94/9/EG as well as of EC conformity are given.
