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:

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 used in accordance with section 3. Technical data. The specified 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.

In the event of a diaphragm leakage, the dosing liquid may leak out of the hole in the intermediate flange between the pump and the dosing head. The parts inside the housing are protected from the dosing liquid for a short time (depending on the type of liquid) by the housing sealing. It is necessary to check regularly (daily) if liquid is leaking out of the intermediate flange. For maximum safety, we recommend the pump version with diaphragm leakage detection.

8.4 Stroke-length adjustment

Warning

Wear protective clothing (gloves and goggles) when working on the dosing head, connections or lines!

Adjust the stroke length only while the pump is running!

The zero point (no dosing) of the dosing pump is factory-set to a counterpressure of 3 bar. See section

If the operating counterpressure at the injection unit deviates considerably from this value, it is advisable to readjust the zero point to obtain more precise values.

1. Install a graduated pipe at the suction valve.

– If such a pipe is not available, insert the suction line into a

graduated measuring jug.

2. Start the dosing pump.

3. Set the dosing flow to 15 %.

4. For pumps with tank-empty indication, remove the electric

plug of the tank-empty indication.

5. Turn the adjustment knob slowly clockwise (towards the zero

point) until the medium level stops falling in the measuring jug or pipe.

6. Remove the plug with a small screwdriver without changing

the position of the adjustment knob and unscrew the cheese-head screw together with the flat spiral spring.

7. Gently pull off the adjustment knob and fit it on the adjusting

spindle so that the zero line on the scale and the mark on the adjustment knob coincide.

8. Screw in the cheese-head screw and the spiral spring until the

spring is preloaded, but does not block. Even when adjusted to 100 %, the spring of the adjustment knob must remain preloaded.

13. Dosing curves.

8.5 Adjustment of stroke rate using a frequency converter

If a frequency converter is connected, the stroke rate can only be adjusted in the range 10-100 % of max. stroke rate. See installation and operating instructions for the frequency converter!

Warning

Observe the manufacturer’s instructions!

The connections must be carried out according to these instructions.

Settings of frequency converter when used with Grundfos dosing pumps

Pay special attention to the following parameters of the frequency converter:

• P013 (maximum motor frequency):

– Set the frequency converter to maximum 100 Hz.

TM03 6309 4506

– Due to this setting, the maximum stroke frequency of the

pump cannot be exceeded.

• P086 (motor current limit):

– Do not change the default setting (150 %). – The motor is protected by a PTC resistor. Therefore, this

parameter is not necessary.

• P081 - P085 (motor data):

– Set these parameters to the values stated on the motor

nameplate.

– Observe the manufacturer’s instructions!

10. Integral relief valve

Operating

Venting

English (GB)

10.1 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.

10.2 Permissible media

Warning

Dosing heads with integral relief valve must not be used for abrasive or crystallising media.

10.3 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.

Warning

When dosing dangerous media, observe the corresponding safety precautions!

Wear protective clothing (gloves and goggles) when working on the dosing head, connections or lines!

10.4.2 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.

TM03 6312 4506TM03 6313 4506

Fig. 24 Setting of opening pressure

Fig. 23 Connections

Warning

Never start the pump if the overflow line is not correctly connected to the relief valve.

10.4 Setting of opening pressure

10.4.1 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.

Warning

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 counterpressure 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 counterpressure. If an exact setting is required, the relief valve must be adapted to the local conditions.

Warning

Never set the opening pressure to values higher than the maximum permissible operating pressure of the dosing system and dosing pump.

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.

10.5 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).

• Once the pump has been completely vented, turn the knob

back into position A "Operating".
