makes commissioning fast and easy. Other accessories are also available to make sure that your Grundfos
DMX fits your system exactly, such as:
Reliable diaphragm dosing
from 1.3 to 2 x 166 GPH.
• back-pressure valves for dosing systems with no or
varying back pressure
• servomotor for remote stroke-length control via
4-20 mA input
TM03 2134 3705
• DMX AR dosing controller with output to indicate a
loss
• DMX AR with leak detection
• DMX with integrated pressure relief valve in the
pump head.

DMX 221 and 226 - versatility through choice
The Grundfos DMX is a series of high-quality mechanically actuated diaphragm pumps suitable for many
uses, such as drinking water treatment, wastewater
treatment, and the pulp/paper and textile industries.
This series is designed to be highly versatile, which is
reflected in the wide flow range covered and the choice
of dosing head sizes, materials, and accessories available. If in doubt, ask us – we will help you configure the
DMX that is best for you.
Manual or remote reliable control
DMX B models feature manual stroke length adjustment for a 10:1 turndown ratio. For additional control
the DMX AR features a micro-processor controller with:
• precise and automatic proportional feed
• manual stroke-frequency control
• 0(4)-20 mA or pulse control
• menu-driven display with user-friendly interface
• low-level and empty output
• remote on/off control.
Choose the materials – and size – that suit you
Both the DMX 221 and 226 liquid ends are available in
PVC, PVDF, polypropylene, and stainless steel. For
additional output and flexibility, the DMX 226 is available in a duplex version.

On the DMX AR, the capacity is set both by setting the
stroke length on the gearbox knob and the stroke frequency on the control unit. The control unit controls the
stroke frequency by starting and stopping the motor
according to the set stroke frequency. Figure 10 shows
two examples:
1. The pump is running at 100% capacity at maximum
stroke length and stroke frequency.
2. The pump is running at 25% capacity at 50% stroke
length and 50% stroke frequency.

Menu levels
Menu levels used in the electronics
• First function level: This level is used for selecting
and setting the pump operating modes (manual,
contact and analog) and starting.
• Second function level: This level is used for setting
and viewing additional functions and setting the access code to protect the pump against unintentional
adjustment.
• Service level: This level is used for setting the inputs and outputs, modifying the version of the Etron
Profi Electronics. It is possible to revert to the default settings.

Deaeration and suction
If the [Start/Stop] button is pressed for more than one
second, the pump switches to continuous operation.
The pump remains in continuous operation as long as
the button is pressed (for example for suction or deaeration).
This occurs regardless of the selected operating mode.
Locking ‘run’
The pump can be locked to avoid manual stopping.
When activating the locking run function (service level),
the pump starts running with the present settings and
cannot be stopped by means of the [Start/Stop] button.
It is still possible to acknowledge error messages using
the [Start/Stop] button.
Functions

Diaphragm Breakage Signal
Remote switching
As an option, the pump can be equipped with a sensor
for Diaphragm Breakage Signal (MBS).
The pump can be switched off remotely, for example
from a control room.
The electronics automatically detects whether a sensor
is connected. The following appears in the display:
• If the pump is switched off remotely, it does not respond to any input signals or to operator input.
Exception: The pump can still be stopped and deaerated manually.

When the sensor detects a diaphragm breakage, the

• The pump is switched off.
The dosing controller monitors the dosing process and
emits a pulse for each dosing stroke.
• The error signal relay switches on.
• During start-up or after 5 seconds of downtime, the
electronics automatically detects whether a dosing
controller is connected. The following appears in the
display:
• The LED flashes red.

Memory function and excess contact signals
Contact signals that cannot be processed immediately,
can be stored and subsequently made available to the
pump for processing. A maximum of 65,000 contact signals can be stored.
• Without memory: If the pump is running when a contact signal is received, the signal is ignored. The
pump executes the current dosing, then it is again
ready to receive new contact signals, i.e. it rejects
excess contacts.
• With memory: If the pump is running when a contact
signal is received, the signal is stored in the memory. First, the pump executes the current dosing,
then it processes the contact signals from the memory.

Construction
DMX
General description
The Grundfos DMX pumps are mechanical diaphragm
dosing pumps. The strokes are generated by an eccentric
which moves the diaphragm by means of a spring-loaded
plunger. The discharge stroke is activated by the eccentric and the suction stroke by the spring return.
The DMX pumps are designed for capacities between 1.3
and 2 x 166 GPH and a maximum pressure up to 232 psi.
The DMX pumps are fitted with a separation chamber. In
the event of a diaphragm failure, the separation chamber
prevents the pumped liquid from flooding the pump unit or
other system components.

• The rotation of the motor is transformed into the reciprocating movement of the dosing diaphragm by
the operation of the eccentric and tappet.
• Adjustment of the dosing flow is possible by adjusting the stroke length.

1) The maximum flow is measured at maximum back pressure.
2) Maximum back pressure.
3) Motor for frequency control.
*) Operation at a back pressure of 232 psi reduces diaphragm life.
The values in the table above are based on the following conditions:
• dosing liquid: water
• flooded suction: 1.6 ft.
• fully vented dosing head
• 400 V motor, 3-phase.
Minimum back pressure: 14.5 psi.
The back pressure refers to the pressure at the pump
discharge valve. Pressure losses in the line to the injection point are not taken into account.

List of pumped liquids
The data shown is based upon information from various
sources available, but be aware that many factors, such
as purity, temperature, abrasive particles, etc. can
affect the chemical resistance of a given material.
This resistance table is intended to serve as a general
guide only for material resistance (at room temperature) and is not a substitute for actual testing of the
chemicals and pump materials under specific working
conditions.
Note: Some of the liquids in this table may be toxic, corrosive or hazardous.
Note: Be careful when handling these liquids.
