4. General information

4.1 Applications

The DMX 221 pump is suitable for liquid, non-abrasive and non­inflammable media strictly in accordance with the instructions in
this manual.

The DMX 221 dosing pumps have not been approved according
to the EC directive 94/9/EC, the so-called ATEX directive. The
application of these pumps in potentially explosive environments
according to ATEX directive is therefore not permitted.

Warnin g
Other applications or the operation of pumps in

ambient and operating conditions, which are not
approved, are considered improper and are not
permitted. Grundfos Alldos accepts no liability
for any damage resulting from incorrect use.

4.2 Warranty

Warranty in accordance with our general terms of sale and
delivery is only valid

• if the pump is used in accordance with the information within

this manual.

• if the pump is not dismantled or incorrectly handled.

• if repairs are carried out by authorised and qualified

personnel.

• if original spare parts are used for repairs.

5. Safety

This manual contains general instructions that must be observed
during installation, operation and maintenance of the pump. This
manual must therefore be read by the installation engineer and
the relevant qualified personnel/operators prior to installation and
start-up, and must be available at the installation location of the
pump at all times.

It is not only the general safety instructions given in this "Safety"
section that must be observed, but also all the specific safety
instructions given in other sections.

5.1 Identification of safety instructions in this manual

If the safety instructions or other advice in this manual are not
observed, it may result in personal injury or malfunction and
damage to the pump. The safety instructions and other advice are
identified by the following symbols:

Warnin g
If these safety instructions are not observed,

it may result in personal injury!

If these safety instructions are not observed,

Caution

Note

Information provided directly on the pump, e.g. labelling of fluid
connections, must be observed and must be maintained in a
readable condition at all times.

it may result in malfunction or damage to the
equipment!

Notes or instructions that make the job easier
and ensure safe operation.

5.2 Qualification and training of person nel

The personnel responsible for the operation, maintenance,
inspection and installation must be appropriately qualified for
these tasks. Areas of responsibility, levels of authority and the
supervision of the personnel must be precisely defined by the
operator.

If the personnel do not have the necessary knowledge, the
necessary training and instruction must be given. If necessary,
training can be performed by the manufacturer/supplier at the
request of the operator of the pump. It is the responsibility of the
operator to make sure that the contents of this manual are
understood by the personnel.

5.3 Risks when safety instructions are not observed

Non-observance of the safety instructions may have dangerous
consequences for the personnel, the environment and the pump.
If the safety instructions are not observed, all rights to claims for
damages may be lost.

Non-observance of the safety instructions may lead to the
following hazards:

• failure of important functions of the pump/system

• failure of specified methods for maintenance

• harm to humans from exposure to electrical, mechanical and
chemical influences

• damage to the environment from leakage of harmful
substances.

5.4 Safety-conscious working

The safety instructions in this manual, applicable national health
and safety regulations and any operator internal working,
operating and safety regulations must be observed.

5.5 Safety instructions for the operator/user

Hazardous hot or cold parts on the pump must be protected to
prevent accidental contact.

Leakages of dangerous substances (e.g. hot, toxic) must be
disposed of in a way that is not harmful to the personnel or the
environment. Legal regulations must be observed.

Damage caused by electrical energy must be prevented (for more
details, see for example the regulations of the VDE and the local
electricity supply company).

5.6 Safety instructions for maintenance, inspection

and installation work

The operator must ensure that all maintenance, inspection and
installation work is carried out by authorised and qualified
personnel, who have been adequately trained by reading this
manual.

All work on the pump should only be carried out when the pump is
stopped. The procedure described in this manual for stopping the
pump must be observed.

Pumps or pump units which are used for media that are harmful
to health must be decontaminated.

All safety and protective equipment must be immediately
restarted or put into operation once work is complete.

Observe the points described in the initial start-up section prior to
subsequent start-up.

Warnin g
Electrical connections must only be carried out

by qualified personnel!
The pump housing must only be opened by

personnel authorised by Grundfos Alldos!

5.7 Unauthorised modification and manufacture of

spare parts

Modification or changes to the pump are only permitted following
agreement with the manufacturer. Original spare parts and
accessories authorised by the manufacturer are safe to use.
Using other parts can result in liability for any resulting
consequences.

5

5.8 Improper operating methods

The operational safety of the supplied pump is only ensured if it is
used in accordance with section 1. General. The specified limit
values must under no circumstances be exceeded.

5.9 Safety of the system in the event of a failure in the
dosing system

DMX 221 dosing pumps are designed according to the latest
technologies and are carefully manufactured and tested.
However, a failure may occur in the dosing system. Systems in
which dosing pumps are installed must be designed in such a
way that the safety of the entire system is still ensured following a
failure of the dosing pump. Provide the relevant monitoring and
control functions for this.

13. Integral relief valve

13.1 Function

If the pump is the only pump in the system, the integral relief
valve (optional) protects the complete discharge side of the
discharge line system from an excessive pressure build-up.

The valve opens if the pressure rises above its set opening
pressure, and the dosing medium can return to the dosing tank.

In contrast to relief valves connected in series, the integral valve
also provides pump protection if the discharge valve is dirty or
blocked.

13.2 Permissible media

Warnin g
Dosing heads with integral relief valve must not

be used for abrasive or crystallising media.

13.3 Connections

1. Connect the suction line to the suction valve (A).

2. Connect the discharge line to the discharge valve (B).

3. Connect the overflow line to the relief valve (C) and allow the
medium to flow by gravity into the tank or to an appropriate
overflow.

Warnin g
When dosing dangerous media, observe the

corresponding safety precautions!
Wear protective clothing (gloves and goggles)

when working on the dosing head, connections
or lines!

13.4.2 Setting the valve opening pressure

To change the factory-set opening pressure, proceed as follows:
The pump must be running.

1. Remove the cap from the top part of the relief valve.

2. Close the isolating valve after the pressure gauge.

3. When overflowing of the dosing medium is heard, read the
current opening pressure on the pressure gauge.

A

Fig. 19 Connections

Warnin g
Never start the pump if the overflow line is not

correctly connected to the relief valve.

13.4 Setting of opening pressure

13.4.1 General

The opening pressure can only be set if a pressure gauge is
installed in the system between the pump and the next isolating
valve or pressure-loading valve.

Warnin g
Settings on the relief valve must only be carried

out by authorised and qualified personnel!

The opening pressure of the relief valve is factory-set to the
maximum pump counter-pressure specified in the technical data.
The opening pressure during operation depends on various
factors, e.g. the flow, the stroke frequency of the pump, or the
counter-pressure. If an exact setting is required, the relief valve
must be adapted to the local conditions.

Warnin g
Never set the opening pressure to values higher

than the maximum permissible operating
pressure of the dosing system and dosing pump.

Fig. 20 Setting of opening pressure

4. Change the pressure as follows:

– To increase the pressure, turn the knob clockwise using

pointed pliers until the desired opening pressure is reached.

– To reduce the pressure, turn the knob counter-clockwise

using pointed pliers until the desired opening pressure is
reached.

5. Open the isolating valve after the pressure gauge.

6. Refit the cap.

13.5 Venting

The relief valve can also be opened manually, thus serving as a

TM03 6311 4506

venting valve at the same time. If manual venting is required (e.g.
during start-up or when the tank has been replaced), proceed as
follows:

• Turn the knob so that the smaller cut-out rests on the nub of
the dosing head (the rotary knob is then further away from the
dosing head). The valve spring is unloaded (position B).

(pull cap approx. 5 mm).

Caution

After initial start-up and after each time the
diaphragm is changed, tighten the dosing head
screws.

After approximately 6-10 operating hours or
two days, cross-tighten the dosing head screws
using a torque wrench.

Maximum torque: 6 Nm.

Fault Cause Remedy

1. Dosing pump does not
run.

2. Dosing pump does not
suck in.

3. Dosing pump does not
dose.

4. Dosing flow of the pump
is inaccurate.

a) Not connected to the power supply. Connect the power supply cable.
b) Incorrect supply voltage. Replace the dosing pump.
c) Electrical failure. Return the pump for repair.
d) The empty indication has responded. Remove the cause.
e) The diaphragm leakage detection has responded. Replace the diaphragm.
a) Leaking suction line. Replace or seal the suction line.
b) Cross-section of the suction line too small or

suction line too long.
c) Clogged suction line. Rinse or replace the suction line.
d) Foot valve covered by sediment. Suspend the suction line from a higher position.
e) Buckled suction line. Install the suction line correctly. Check for

f) Crystalline deposits in the valves. Clean the valves.
g) Diaphragm broken or diaphragm tappet torn out. Replace the diaphragm.
a) Air in the suction line and dosing head. Wait, until the pump has deaerated.
b) Stroke-length adjustment knob set to zero. Turn the adjustment knob in the "+" direction.
c) Viscosity or density of medium too high. Check the installation.
d) Crystalline deposits in the valves. Clean the valves.
e) Valves not correctly assembled. Assemble the inner valve parts in the right order

f) Injection point blocked. Check and possibly correct the flow direction

g) Incorrect installation of lines and peripheral

equipment.
a) Dosing head not fully deaerated. Repeat the deareation.
b) Degassing medium. Check the installation.
c) Parts of the valves covered in dirt or incrusted. Clean the valves.
d) Zero point misadjusted. Adjust the zero point to the actual counter-

e) Counter-pressure fluctuations. Install a pressure-loading valve and a pulsation

f) Suction height fluctuations. Keep the suction level constant.
g) Siphon effect (inlet pressure higher than counter-

pressure).
h) Leaking or porous suction line or discharge line. Replace the suction line or discharge line.
i) Parts in contact with the medium are not resistant

to it.
j) Dosing diaphragm worn (incipient tears). Replace the diaphragm. Also observe the

k) Supply voltage fluctuations. Decrease the counter-pressure of the pump.
