Warning

These complete installation and operating
instructions are also available on
www.grundfos.com.

Prior to installation, read these installation and
operating instructions. Installation and operation
must comply with local regulations and accepted
codes of good practice.

1. General information

1.1 Introduction

These installation and operating instructions contain all the
information required for starting up and handling the DMX 221
dosing pump.

If you require further information or if any problems arise, which
are not described in detail in this manual, please contact
Grundfos.

1.2 Applications

The DMX 221 pump is suitable for liquid, non-abrasive and
non-flammable 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.

Warning

Other applications or the operation of pumps in
ambient and operating conditions, which are not
approved, are considered improper and are not
permitted. Grundfos accepts no liability for any
damage resulting from incorrect use.

1.3 Warranty

A guarantee claim in accordance with our general terms of sale
and delivery is only valid if the following requirements are fulfilled:

• The product is used in accordance with the information within
this manual.

• The product is not dismantled or incorrectly handled.

• The maintenance is carried out by authorised and qualified
personnel.

2. 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.

2.1 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:

If these safety instructions are not observed,
it may result in personal injury!

If these safety instructions are not observed,
it may result in malfunction or damage to the
equipment!

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

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.

Warning

Electrical connections must only be carried out
by qualified personnel!

The pump housing must only be opened by
personnel authorised by Grundfos!

2.7 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.

English (GB)

2.2 Qualification and training of personnel

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.

2.3 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.

2.4 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.

2.5 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).

2.6 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.

2.8 Improper operating methods

The operational safety of the supplied pump is only ensured if it is

limit values must under no circumstances be exceeded.

2.9 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.

Ensure that the enclosure class of motor and
pump are not affected by the atmospheric
conditions.

Pumps with electronics are only suitable for
indoor use! Do not install outdoors!

Warning

Risk of hot surfaces!

Pumps with AC motors may become hot.
Allow a minimum space of 100 mm above the fan
cover!

• Sound pressure level: ± 55 dB(A), testing according to
DIN 45635-01-KL3.

• Minimum counterpressure: 1 bar at the pump discharge valve.
Pay attention to the pressure losses along the way to the
injection point inclusively.

Maximum permissible mains impedance: 0.084 + j 0.084 Ω
(testing according to EN 61000-3-11).

3.6 Dosing medium

In the event of questions regarding the material
resistance and suitability of the pump for specific
dosing media, please contact Grundfos.

The dosing medium must have the following basic characteristics:

• liquid

• non-abrasive

• non-flammable.

3.7 Electrical data

3.7.1 Enclosure class

The enclosure class depends on the motor variant selected, see
motor nameplate.

The specified enclosure class can only be ensured if the power
supply cable is connected with the same degree of protection.

Pumps with electronics: The enclosure class is only met if the
sockets are protected! The data regarding the enclosure class
applies to pumps with correctly inserted plugs or screwed-on
caps.

3.7.2 Motor

Version: see motor and pump nameplates.

3.8 AR control unit

Functions of pumps with electronics:

• "Continuous operation" button for function test and dosing
head deaeration

• memory function (stores a maximum of 65000 pulses)

• two-stage tank-empty signal (e.g. via Grundfos tank empty
sensor)

• stroke signal/pre-empty signal (adjustable), e.g. as a feedback
to the control room

• dosing controller function (only with sensor - optional)

• diaphragm leakage detection (only with sensor - optional)

• access-code-protected settings

• remote on/off

• Hall sensor

• operating hours counter

• motor monitoring.

Operating modes:

• manual
Stroke frequency: manually adjustable between zero and
maximum

• contact signal control
Multiplier (1:n) and divisor (n:1)

• current signal control 0-20 mA / 4-20 mA
Adjustment of stroke frequency proportional to the current
signal.
