General data DMS
DME and DMS
Digital Dosing
Digital Dosing represents state-of-the-art technology.
This patented Grundfos solution sets new standards,
including new principles and methods.
Precise and easy setting
The operator can easily install and set the pump to
discharge exactly the quantity of dosing liquid required
in the application. Capacity is read on the digital display
in GPH, l/h, or ml/h, while icons are used to identify the
operation mode.
Unique technology
A unique drive and microprocessor control ensure that
dosing liquids are discharged precisely and with low
pulsation even when the pump is operating with high
viscosity or degassing liquids. Instead of the conven-
tional stroke length adjustment, the capacity of the
DME is regulated by automatic ajustment of the motor
speed during the discharge stroke and by fixed suction
stroke speed, ensuring optimal and uniform mixing. The
capacity of the DMS is regulated by automatic regula-
tion of the stroke frequency.
Fewer variants to cover all needs
The powerful variable speed motor, a turn-down ratio of
1:1000/1:800 and a complete control interface including
• full pulse control,
• pulse batch control,
• internal timer batch control,
• analog 0/4-20 mA control,
• level control and
• fieldbus communication module
ensure that nine DME pumps cover the range from
0.00066 to 248.3 gallons per hour, up to 261 psi. The
switch mode power supply ensures that the same pump
is working precisely, irrespective of the power supply
(100-240 V; 50-60 Hz).
The DMS version with synchronous motor and a turn-
down ratio of 1:100 (consisting of four pump sizes and
two control versions) cover the range from 0.0066 to
3.17 GPH. The DMS-A pumps have external pulse,
analog 4-20 mA and level control interface; the DMS-B
version is without external control interface. The DMS-
D is without control and user interface.
The DME and DMS dosing pumps feature diaphragm
dosing head with integrated vent valve, suction and
discharge ball valves.
The pumps are also fitted with a power cable and plug.

DME
Functions
Capacity control, DME
The electronically controlled variable-speed motor of
the DME pumps provides optimum control of the stroke
speed. As shown in the figure below, the duration of
each suction stroke is constant while the duration of
each discharge stroke varies according to the capacity
set, resulting in optimum discharge flow in any oper-
ating situation.
The advantages are as follows:
• The pump is always operating at full stroke length,
irrespective of the capacity set, for optimum accu-
racy, priming and suction.
• A capacity range of 1:1000 (DME 2 to 48) for each
pump size.
• A capacity range of 1:800 (DME 60 to 940) for each
pump size.
• Even and constant dosing ensuring an optimum
mixing ratio at the injection point.
• Significant reduction of pressure surges, preventing
mechanical stress on diaphragm, tubes, connec-
tions and other dosing parts exposed to leakage
and wear.
• The installation is less affected by long suction and
discharge lines.
• Easier dosing of highly viscous and gas-containing
liquids.
The optimum dosing control shown below takes place
in any operating mode.

Functions DMS
Capacity control, DMS
The electronically controlled synchronous motor of the
DMS offers similar advantages of the DME pumps. As
shown in the figure below, the suction and discharge
stroke speeds are constant while the stroke frequency
varies according to the capacity set.
The sinusoidal movement of the diaphragm offers the
following advantages:
• The pump is always operating at full stroke length,
irrespective of the capacity set, for optimum accu-
racy, priming and suction.
• A capacity range of 1:100 for each pump size.
• Reduction of pressure surges, preventing mechani-
cal stress on diaphragm, tubes, connections and
other dosing parts exposed to leakage and wear.
• The installation is less affected by long suction and
discharge lines.
• Easier dosing of highly viscous and gas-containing
liquids.

Control panel
Control panel fitted to the front.
Control panel fitted to the side (not DMS-B).
Priming button
The pump control panel incorporates a button.
Press this button if the maximum capacity is required
over a short period, e.g. during start-up. When the
button is released, the pump automatically returns to
the previous operating mode.
When the buttons and are pressed simultane-
ously, the pump can be set to run for a specific number
of seconds at maximum capacity. The remaining
numbers of seconds will appear in the display. This
feature is useful when flushing the pump. The
maximum value is 300 seconds.
Press to stop the pump before the set time has
passed.
Indicator lights and alarm output
(DME 2 to 48, DMS)
The green and red indicator lights on the pump indicate
operation or fault.
In control variant AR, the pump can activate an external
alarm signal by means of a built-in alarm relay. The
alarm signal is activated by means of an internal poten-
tial-free contact.
The functions of the indicator lights and the built-in
alarm relay appear from the table below.
