INSTALLATION IN EXPLOSIVE AND
FIRE DANGER ZONES
Micropump oers products designed and tested for installation in explosive or re
danger zones. Contact your local Micropump distributor or contact Micropump directly
to deter mine if your EagleDrive product combination can be certied for this use.
In addition to the warnings provided throughout this manual, the following must be
consid ered in any explosion or re danger zone installation:
DESCRIPTION
The EagleDrive is a brushless DC motor with integrated controller specially designed
to be electromagnetically coupled to a variety of Micropump pump heads. When
properly assembled to the pump head with sealing o-ring, this comprises a sealed
unit where the driven magnet is within a magnet cup that separates the pumped uid
from the atmosphere.
There are two EagleDrive models, the DEMSE and DEELE. The enclosed versions
are within a thermoplastic housing. The motor is capable of rotating in both
directions and has speed control input options. A tachometer signal, with a 0-5 V
square-wave output provides speed feedback. The tachometer output has 2 pulses
per revolution. The output frequency is multiplied by 30 to obtain RPM. The main
input power is 12-36 VDC from a class 2 (SELV) source.
Both EagleDrive models can be controlled using one of these options:
1. Externally applied 0-5 VDC supply
2. Externally applied PWM
(Pulse Width Modulation) signal
3. Externally applied 4-20 mA signal
(conditioned with external resistor)
4. Manually-adjusted speed
control (through use of external
potentiometer)
FUNCTION
The driven magnet is connected to the pumping parts and is sealed in the magnet
cup. This magnet forms the rotor of the brushless DC motor and is driven by the
rotating magnetic eld in the stator. Rotation of the pumping elements produces ow.
The control signal (supplied internally or externally) controls pump speed. Internal
feedback monitors the rotational speed of the pump and regulates the speed in
relation to the control voltage. The controller increases current to regulate speed
against increasing back pressure (within the operating limits of the pump and motor).
Ensure the pump head,
motor, and any mounting
adapter are suitable for
area classication.
Ensure that pumping liquid
temperature, and motor
housing temperature are
maintained within acceptable
range as specied by
Micropump Certication of
ATEX Conformity.
