1. General Description
The MAGDOS DE/DX is an intelligent solenoid driven
metering pump that combines digital technology
and state-of-the-art microprocessors with high
quality mechanics. The MAGDOS series is flexible
and versatile in the area of external control. Its
functionality incorporates the latest requirements in
metering technology.
The MAGDOS is available in two versions, the DE
and the DX. Both versions include microprocessor
control. Two chassis sizes of the MAGDOS are
available. The smaller chassis can be used for
capacities ranging from 0 to 2.8 gph and the larger
chassis for capacities ranging from 0 to 27.7 gph.
Pressure ranges are available to 150 psi,
depending on capacity.
2. System Design Guidelines
Before installing the MAGDOS DE/DX into a new or
existing system, Lutz-JESCO America Corporation
recommends careful review of your system’s design
and layout. It is essential that all local rules, codes
and regulations are followed in the design and
installation of chemical feed equipment. It is also
important that the system meets the technical
demands required, such as flow rates and
pressures. Many factors must be taken into
consideration, including process fluid
specifications, material compatibilities,
temperature, chemical handling, electrical wiring,
line losses and many more.
Ambient temperatures exceeding 104oF are not
permitted. Radiant heat of surrounding equipment
must be kept in acceptable limits to allow the
pump to sufficiently dissipate its own heat.

Exposure to direct sunlight must be avoided. If the
pump is installed outside, provide an enclosure to
protect it against the weather. With metering pump
systems, particular attention must be paid to the
piping system. Refer to the System Design Guide
for more detailed information. (If in need of a
System Design Guide, contact Jesco America
Corporation).

technical failure.
It is especially important that chemical plants be
designed to ensure the safety of maintenance
people and operators. We recommend installing
relief valves, splashguards, containment tanks,
and leakage probes with alarm relays to aid this
effort.
MAGDOS DE/DX pumps with integrated level
control function are equipped with a short-circuit
jack plug which must be removed before
connecting a level control by means of a jack plug.
A weather tight cable is available if using a level
control to keep the NEMA 4x protection class.
Wiring of the MAGDOS metering pump must be
carried out by a specialist according to the local
regulations. Normally the MAGDOS is connected
with a grounded plug. Please see the MAGDOS DE/
DX Specification Sheet for all electrical data.
Mounting the metering pump directly on a water
meter may result in noise level amplification. In
this case, we recommend that you mount the
pump on separate wall brackets which, for the
same reason, should be fixed to outer walls
instead of interior walls with adjacent occupied
rooms. It is also possible to mount the pump
directly on the supply tank.
Do not lay signal cables of water meters or
0(4)...20 mA controls parallel to high-voltage
current or power supply lines. Supply and signal
lines must be laid in separate channels. In the
case of junctions, a 90Þ angle is required. If the
water meter control cable is more than 6 feet long,
it must be shielded. To avoid incorrect metering
after the process is finished, provide an electric
and hydraulic interlocking system.

3. Safety Precautions
The diaphragm metering pump is designed to
pump various liquids into pressurized systems. By
nature, the application of these pumps may
present circumstances under which personal
hazards can exist. All personnel who may have
occasion to install, operate, or maintain these
pumps should be provided with the opportunity to
read this instruction manual and be familiar with
its contents. Awareness of potential hazards can
prevent accidents and injury.
Danger from Liquids HandledDanger from Liquids Handled
Danger from Liquids HandledDanger from Liquids Handled
Danger from Liquids Handled
All systems containing liquid and/or air under
pressure present the potential for unexpected
discharge of liquid in a violent manner. In
operation and servicing of the pump, all parts of
the pump and attached piping which contain liquid
should be treated cautiously, until it is known with
certainty that they have been depressurized and
drained.
Danger from Electrical HazardDanger from Electrical Hazard
Danger from Electrical HazardDanger from Electrical Hazard
Danger from Electrical Hazard
Since these pumps include electric components,
the hazard of electrical shock can exist.
Installation and wiring of electrical components
should be in accordance with the applicable
codes.
Operational HazardsOperational Hazards
Operational HazardsOperational Hazards
Operational Hazards
To avoid personal injury, please adhere to the
following guidelines:
1. Do not operate the pump if electrical compo-
nent enclosures are not in place.
2. When venting cylinders or piping during startup,
liquid will be discharged under pressure. The
use of a pressure relief valve back to the
supply tank is highly recommended. Suitable
caution should be taken to avoid contact with
the liquid and to avoid spillage or spraying of
liquid.
3. Clean up any leaked or spilled liquid immedi-
ately.

3. Observe all chemical handling instructions
provided by the chemical supplier and/or plant
regulations.
4. Do not operate pump with closed valves in
suction and/or discharge lines.
5. Do not paint over or remove nameplates, labels,
or tags.
6. In disassembly of pump, precautions should be
taken for the possibility that a diaphragm
rupture may have allowed pumped liquid to
enter the drive system.
7. If a pump is to be used for other than original
service, first ascertain that pump is suitable for
new conditions (pressure and compatibility with
liquid to be pumped).
8. Establishment of and adherence to a regular
maintenance program can prevent problems by
early detection of unusual conditions (e.g.
unusual noise, overheating, and wetness
indicating leakage).
4. Installation
The accuracy and reliability of a metering pump
system depends on proper installation of each
component. All considerations of sound hydraulic
practice, including the elimination of air and foreign
matter, accurate and reliable seating of check
valves, proper size and length of piping, liquid
vapor pressure, viscosity, and temperature may
mean the difference between a successful or
unsuccessful installation. The application of basic
hydraulic principles during planning, installation
and operation is essential. Good suction conditions
will prevent a common cause of premature
diaphragm failures. Each installation should be
designed and built paying careful attention to all
instructions regarding handling of corrosive, toxic or
hazardous chemicals. It is of utmost importance
that all safety procedures established by the
owners and manufacturers be followed during
installation, operation and maintenance phases.
LocationLocation
LocationLocation
Location
The preferred location of a metering pump system
is indoors. Although systems can be installed
outdoors, manufacturer’s temperature ratings and
recommendations must be followed. System fluids
are subject to viscosity increase when
temperatures fall. Drive units are subject to
overheating when installed in direct sunlight or an
area with high ambient temperatures. If a system
must be installed outdoors, it should be sheltered
from the elements with heating or cooling systems
as needed. Proper installation indoors or out
should allow sufficient room for operators and
maintenance personnel to access each component
for adjustments and servicing.

1. For first startup, set pump to maximum stroke
speed and stroke length and allow to prime.
For this purpose, it is advisable to set both
stroke adjustments to 100%. If the pump
doesn’t prime, remove discharge check valve
and pour water or chemical (if harmless) into
head. Mount the discharge check valve and
allow to prime again.
2. If a venting aid is integrated in the metering
head or is available as separate unit, open it
and wait until liquid escapes. Then close it
again. In the case of effervescent liquids, allow
the liquid to escape permanently (approxi-

mately 1 drop for 1-3 strokes).
3. When proper operation is achieved, set stroke
length to required output and lock adjusting
knob. Refer to the calibration table on the side
of pump to get the stroke length setting for a
selected output (ml/stroke). The back
pressure influences are taken into consider-
ation in the table, and intermediate values
must be interpolated. Depending on the
installation and the chemicals used, these
values may differ and must be checked
under operating conditions. See Calibration
Table below.
4. In the case of externally actuated pumps (e.g.
by water meters), set pump to “external.”
Initiate the water flow by opening a water
valve and check pump pulse rate. The
manufacturer of the metering equipment is
not responsible for damages due to excessive
or low flow rates resulting from faulty pump
settings or incorrect and insufficient installa-
tion of peripheral fittings.

In order to protect the pump against overheating,
the maximum input frequency is limited to 100/
70 pulses/minute; therefore, input frequency is
higher, each third or fourth metering stroke is not
carried out. Therefore, external pulse transmitters
should be selected so that the pump is controlled
with a maximum of 100/70 strokes/minute,
depending on model selected, otherwise use the
pulse division feature (DX only).

screw and turn the stroke length adjustment
knob counterclockwise until the pump no
longer delivers or, in the case of no pressure
delivery, the flow rate has reached the mini-
mum.
2. If zero delivery could not be attained because
the knob reached the stop position:
- Loosen and remove locking screw and knob.
- Turn knob to right and place back on pump
with loose locking screw.
- Turn knob to left until pump no longer delivers
fluid.
- Turn pump off and by removing locking screw
and knob, orient knob to zero of dial indicator;
