1. General description
The GRUNDFOS DME dosing pump is a self-priming
diaphragm pump.
The pump c on sis t s o f:
•a cabinet incorporating the drive unit and elec-
tronics,
•a dosing head with back plate, diaphr ag m,
valves, connections and vent valve and
•a control panel incorporating display and but tons.
The control panel can be fitted either to the end or
to the side of the cabinet.
Being equipped with a stepper motor, this dosing
pump is unique in its field. The stepper motor offers
the possibility of varying the capacity by changing
the duration of the dosing stroke.
Furthermore, the mot or is co nt rolled in s uch a wa y
that the dosing gets as even and constant as possible, irrespective of the capacity range in which the
pump is oper a ting.
This is carried out as follows:
The speed of the suction stroke is kept constant and
the stroke relatively short, irrespective of the capacity. Contra ry to con v en tional pump s, whic h gener ate
the dosing st ro ke as a short pu l se, th e du ration of
the dosing stroke will be a s lo ng a s po ssible. Th us,
an even dosing without peak values is ensured. As
the pump is always dosing at full stroke length, it ensures the same high accuracy and suction capability,
irrespective of the capacity, which is infinitely variable in the ratio of 1:1000 .
The pump features an LCD display and a userfriendly control panel whi ch giv es acce ss to the
pump functions .
1.1 Applications

3. Installation
3.1 Safety in structions
• When wor kin g w ith ch emica ls, lo ca l sa fety r ules
and regulations must be observed (e.g. wear protective clothes).
• Before starting work on the dosing pump and system, disconnect the electricity supply to the pump,
ensuring that i t ca nn ot be a ccidentally switche d
on. Before reconnecting the ele ctr icity sup ply,
make sure that the dosing hose is positioned in
such a way that any chemical left in the dosing
head is not ej ect ed , the r eby expos ing persons to
danger.
• If the vent valv e in the do sin g head i s used, i t must
be connected to a hose which is led back to the
tank.
• When changing a chemical, make sure that the
materials of the dosing pump and system are resistant to the new c he mic al. If th e re is any r isk of
chemical reaction between the two types of chemicals, clean the pump and system thoroughly before adding the new chemical.
Proceed as follows:
Place the suction tub e in wate r and pr ess the
button until residual chemical has been removed.
Note: When the buttons and are pressed
simultaneously, the pump can be set to run for a
specific number of seconds at maximu m ca pa cit y.
The remaining number of se cond s w ill a ppea r in
the display. The maximum value is 3 00 s eco n ds.
3.2 Installation environment
• Expos ure to dir ect sun lig ht shou ld be avoided.
This applies especially to pu m ps with p la stic d osing heads, as this material can be damaged by
sunlight.
• If the pump is instal le d ou tsi d e, a n en clo su re o r
similar protection is requir ed t o pr otect the pump
against rain and simil ar weath ers.
3.3 Installation of pump
• See also the installation example in section
3.4
.
• Note: The dosing head may contain water from
the factory test. If a liquid which must not come
into contact with wate r is to be d os ed , i t is r eco m mended to le t th e pu mp run with an ot he r l iqu id to
remove the water from the dosing head before installation.
• Always install the pump on the supporting foot
with vertical suction and discharge ports.
• Always use suitable tools for the mounting of plastic parts. Never apply un ne ce ssa ry force.
• Make sure that the dosing pump and system are
designed in such a way that neither system equipment nor buildings are dama ged in ca se of leakage from the pump or rupture of hoses/pipes. The
installation of l e ak ag e ho ses and collectin g ta nk s
is recommended.
• Make sure th at the drain hol e in th e dosing head
points downwards, see fig. 1.
Note: It is important that the drain pipe/ho le is not
inserted dir ec t in to the tank conten ts, as ga sse s
may penetrate into the pump.

required ove r a s ho rt p er iod , e.g. during st ar t- up .
When the button i s rel ea se d, th e pu mp au t oma tic a lly
returns to the previou s oper at ing mod e.
During priming/venting, it is recommended to let the
pump run without a counter pressure or to loosen the
vent valve by giving it a 1/8 to 1/4 turn.
Note: When the butt on s and are pr ess ed si-
multaneously, the pump can be set to run for a specific number of seco nd s a t ma ximu m ca pacity. The
remaining number of seco nds will appear in the dis play. The maximum value is 300 seconds.
4.4 Level control
The pump can be fitted with a level control unit for
monitoring of the chemical level in the tank.
The pump can react to two level signals. The pump
will react differently, depending on the influenc e on
the individual level sensors.
* Control variant “AR” o nl y.

if the pump has been calibrated to the actual installation, see section
6
.
The pump can run in five different operating modes:
•Manual
•Pulse
•Analog
•Timer (internal batch control)
• Batch (external batch control)
See description in the following sections.
4.9 Manual
The pump is dosi ng as constantl y and evenly as possible, without a ny ex te rn al sig na l s.
Set the quanti ty to be dosed in l/h or ml/h. The pump
automatically ch a ng es over betwee n th e me as ur i ng
units.
Setting range:
DME 2: 2.5 ml/h - 2.5 (1.8*) l/h
DME 8: 7.5 ml/h - 7.5 (5.6*) l/h
DME 12: 12 ml/h - 12 (9*) l/h
DME 19: 18.5 ml/h - 18.5 (14.5*) l/h
DME 48: 48 ml/h - 48 (37*) l/h
* The figures in brac kets ind icat e the ma ximum ca-
pacity when the anti-ca vitation fu nction is activated.
Fig. 6
4.10 Pulse
The pump is dosing according to an external pulse
signal, i.e. a water meter with pulse output or a controller.
Set the quantity to be dosed per pulse in ml/pulse.
The pump adjusts its capacity acco rding to two factors:
• Frequency of external pulses.
• The set quantity per pulse.
Setting range:
DME 2: 0.000018 m l/pulse - 5 ml/pulse
DME 8: 0.000069 m l/pulse - 15 ml/pulse
DME 12: 0.000111 ml/puls e - 24 ml/pulse
DME 19: 0.000204 ml/puls e - 37 ml/pulse
DME 48: 0.0053 0 ml/pulse - 96 ml/pulse
Fig. 7
If the set qu an tit y p e r p u lse mu l ti pl ie d by the pulse
frequency exceeds the pump capacity, the pump will
run at maximum capacity. Exc es s p uls es will be ig nored and the “actual capacity” display will flash.
4.11 Analog
The pump is d osin g according to a n ex te rn al an alog
signal. The dosed quantity is proportional to the input
value in mA.
4-20 (default): 4 mA = 0%.
20 mA = 100%.
20-4: 4 mA = 100%.
20 mA = 0%.
0-20: 0 mA = 0%.
20 mA = 100%.
20-0: 0 mA = 100%.
20 mA = 0%.
See fig. 8.
The capacity limitatio n will i nfl uenc e t he capacity.
100% corresponds to the maximum capacity of the

4.12 Timer
The pump is dosing th e s et quan ti t y in bat che s a t t he
maximum capacity or the set maximum capacity, see
section
4.15
.
The time until the first dosing “NX” and the following
sequences “IN” c an b e set in m i nu te s, ho u rs an d
days. The maxim um t i me li mi t is 9 days, 23 ho ur s
and 59 minut es (9 :2 3: 59 ). T he l o we st acceptable
value is 1 minute.
The interna l time r cont inues even
if the pump is stopped by means of the on/off button,
empty tank or stop signal , see fig . 11.
During operation, “NX” will alwa ys cou n t dow n fro m
“IN” to zero. In th is way, the remaining tim e un til th e
next batch can a l wa ys be r ea d.
“IN” must be higher than the time required to perform
one batch. If “IN” is low er, t he n ext b at ch will be ig nored.
In case of supply fa ilu re , the s et qu a nti ty to be
dosed, the “IN” time and the remaining “NX” time are
stored. When the sup ply is re conn ecte d, the pu mp
will start up with the “NX” time at the time of the supply failure. In this way , t he ti me r cyc le will c ontin ue ,
but it has been delayed by the duration of the supply
failure.
Fig. 11
Setting range:
DME 2: 0.23 ml/batch - 5 l/batch
DME 8: 0.69 ml/batch - 15 l/batch
DME 12: 1.11 ml/batch - 24 l/batch
DME 19: 2.04 ml/batch - 37 l/batch
DME 48: 5.3 ml/batch - 96 l/batch
Only values corresponding to complete dosing
strokes (accordi ng to t he ca lib ra tio n fa ctor) ca n be
selected.
Example: If the calibration factor is 23.3 (= 0.233 ml/
stroke), the minim um se tta bl e val ue in time r or batch
mode will be 0.233 ml -> the n ext will be 0 .4 66 ml ->
the next will be 0.699 ml, etc.
These steps wi ll continue up to a value correspond ing to 100 dosing strokes. Abov e this val ue, the set ting range has standard steps as in other operating
modes.
If the calibration f ac tor is changed after se ttin g of
timer or batch mode , the p ump will automatically recalculate a new amount of dosing strokes per batch
and change the dis pl a y val ue to t he ne ar est pos s ibl e
value compared to the first one set.

4.14 Anti-cavitation
The pump features an anti-cavitation function. When
this function is selected, the pump extends and
smooths its suct ion stroke, resulting i n s of te r pr iming.
The anti-cavitation function is used:
• when pu mp in g liquids of high viscosity,
• in the case of a long suction tube and
• in the case of a high suction lift.
The maximum pump capacity is reduced when this
function is selected. See section

The dosing moni tor is desig ned t o moni tor the dos ing
of liquids whi c h ma y cau se g as accumulation in the
dosing head, thus stopping the dosing process even
if the pump is still ope ratin g.
For every meas ur ed d osing stroke, t he d os ing m on i tor gives a pulse signal to the level input so that the
pump can compare performed dosing strokes (from
internal stroke sensor) with externally measured
physical strokes (from the dosing monitor). If an external dosing str o ke is n o t m e asu re d to ge th er wi th
the internal dos ing stroke, this is co ns ide re d a fa ult
that may have been provoked by empty tank or gas
in the dosing head.

6.3 Check calibration
In check calibration, the c alibra tio n value is ca lculated by reading the consumption of chemical in a
specific perio d and co mpar ing this with the number
of dosing strokes performed in the same period.
This calibration method is very accurate and especially suitable for check calibration after long periods
of operation or if d i re ct c ali b rat i on is i m po ssible. Th e
calibration can for instance be carried out when the
chemical tank is replac ed o r fille d.
To carry out a check calibration, proceed as follows:
1. Stop the pump by pr es sin g the button.
2. Read the counter and note the number of dosing
strokes, see s e ction
4.16
.
3. Read and note the quantity in t he ch e mical tank.
4. Start the pump by pressing the button and let
it run for at least 1 hour. The longer the pump is
operating, the more accurate the calibration will
be.
5. Stop the pump by pr es sin g the button.
6. Read the counter and note the number of dosing
strokes, see s e ction
4.16
.
7. Read and note the quantity in t he ch e mical tank.
8. Calculate the dose d quantity in m l a nd t he
number of dosing strokes pe rfor med du rin g the
operating period.
9. C alcula te the calibration value as follows:
(dosed quantity in ml/dosin g s t rokes) x 100.
10.Se t the cal cul ate d value in the calib ration menu
like for indirect calibration, see se ct ion
6.2

7. Maintenance
The pump is maintenance-free. However, it is recommended to kee p th e p ump clean.
The dosing pump is produced according to the highest quality standards and has long life. The pump incorporates wear part s such as di aphra gm, v alve s eat
and valve balls.
To ensure long life and to reduce the risk of disturbance of operation, visual checks should be carried
out regularly.
It is possible to order dosing heads, valves and diaphragms in ma te ri a ls which are suit ab le fo r the specific liquid to be pumped. See the product numbers
at the end of these instructions.
8. Service
