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

The DME dosin g pu m p is designed f or h an dl in g
chemicals within the following ranges of applications,
among others:

• Drinking water treatment.

• Wastewater treatment.

• Swimming pool water treatment.

• Boiler water treatment.

• Cooling wate r tr ea tm en t.

• Proc ess wate r tr ea tm en t.

• Washing sy ste ms.

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.
