DME and DMS 

Digital Dosing 

Digital Dosing represents state-of-the-art technology. 

This patented Grundfos solution sets new standards, 

including new principles and methods. 

Precise and easy setting 

The operator can easily install and set the pump to 

discharge exactly the quantity of dosing liquid required 

in the application. In the display, the setting of the pump 

is read out directly in ml/h or l/h, pulse or batch, and the 

operation mode is easily identified by means of icons. 

Unique technology 

A unique drive and microprocessor control ensure that 

dosing liquids are discharged precisely and with low 

pulsation even when the pump is operating with high 

viscosity or degassing liquids. Instead of the conventional 

stroke length adjustment, the capacity of the 

DME is regulated by automatic ajustment of the motor 

speed during the discharge stroke and by fixed suction 

stroke speed, ensuring optimal and uniform mixing. The 

capacity of the DMS is regulated by automatic regulation 

of the stroke frequency. 

GR7777r 

DME and DMS 

Fewer variants to cover all needs 

The powerful variable speed motor, a turn-down ratio of 

1:1000/1:800 and a complete control interface including 

• full pulse control, 

• pulse batch control, 

• internal timer batch control, 

• analog 0/4-20 mA control, 

• level control and 

• fieldbus communication module 

ensure that nine DME pumps cover the range from 0 to 

940 litres per hour up to 18 bar. The switch mode power 

supply ensures that the same pump is working 

precisely, irrespective of the mains supply (100-240 V; 

50-60 Hz). 

The DMS version with synchronous motor and a turndown 

ratio of 1:100 (consisting of four pump sizes and 

two control versions) cover the range from 0 to 12 l/h. 

The DMS-A pumps have external pulse, analog 4-20 

mA and level control interface; the DMS-B version is 

without external control interface. The DMS-D is 

without control and user interface. 

The DME and DMS dosing pumps feature diaphragm 

dosing head with integrated vent valve, suction and 

discharge ball valves. 

The pumps are fitted with power cable and plug. 

See page 5 and onwards for further information.

Functions 

Functional description, DME 

The electronically controlled variable-speed motor of 

the DME pumps provides optimum control of the stroke 

speed. As shown in the figure below, the duration of 

each suction stroke is constant while the duration of 

each discharge stroke varies according to the capacity 

set, resulting in optimum discharge flow in any operating 

situation. 

The advantages are as follows: 

• The pump is always operating at full stroke length, 

irrespective of the capacity set, for optimum accuracy, 

priming and suction. 

• A capacity range of 1:1000 (0-48 l/h) for each pump 

size.

Functional description, DMS 

The electronically controlled synchronous motor of the 

DMS pumps offers almost the same advantages as 

those of DME pumps. As shown in the figure below, the 

suction and discharge stroke speeds are constant while 

the stroke frequency varies according to the capacity 

set. The sinusoidal movement of the diaphragm offers 

the following advantages: 

• The pump is always operating at full stroke length, 

irrespective of the capacity set, for optimum accuracy,

Pulse control 

Applies to DME and DMS-A 

The pump is dosing according to an external pulse 

signal, e.g. from a water meter. 

There is no direct relation between pulses and dosing 

strokes. The pump automatically calculates its optimal 

speed to ensure the required quantity is dosed for each 

pulse. The quantity to be dosed is set in ml/pulse. The 

pump adjusts its speed and/or stroke frequency 

according to two factors: 

• frequency of external pulses and 

• the set quantity per pulse. 

Setting range, DME: 

DME 2-18: 0.000023 ml/pulse - 5.0 ml/pulse

Setting range, DMS: 

DMS 2: 0.00232 ml/pulse - 50 ml/pulse 




Analog 4-20 mA control 


The pump is dosing according to an external analog 

signal. The dosed capacity 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%. 

The maximum capacity limitation, see page 13, will 

influence the capacity. 100% (20 mA) corresponds to 

the maximum capacity or the set capacity limitation.

Applies to DME 

The pump is dosing the set quantity in batches at 

maximum capacity or the set capacity limitation. 

The time until the first dosing (NX) and the following 

sequences (IN) can be set in minutes, hours and days. 

The maximum time limit is 9 days, 23 hours and 59 

minutes (9:23:59) The lowest acceptable value is one 

minute. IN must be higher than the time required to 

perform one batch. If IN is lower than the time required, 

the next batch will be ignored. 

In case of supply failure, the set dosing quantity, the IN 

time and the remaining NX time are stored. When the 

supply is reconnected, the pump will start up with the 

NX time at the time of the supply failure. This way the 

timer cycle will continue, but it will be delayed according

Anti-cavitation (0-48 l/h) 


When this function is selected, the pump extends and 

smooths its suction stroke, resulting in softer priming. 

The anti-cavitation function is used: 

• when pumping liquids of high viscosity 

• when pumping degassing liquids 

• in the case of a long suction tube and 

• in the case of a high suction lift. 

The maximum capacity is reduced when this function is 

selected, see below. 

DME 2: 1.8 l/h 

DME 8: 5.6 l/h 

DME 12: 9 l/h 

DME 19: 14.5 l/h 

DME 48: 37 l/h. 

Anti-cavitation (60-940 l/h) 

The pump features an anti-cavitation function. When 

this function is selected, the pump extends and 

smoothes its suction stroke, resulting in softer priming. 

The anti-cavitation function is used: 

• when pumping liquids of high viscosity, 

• in the case of a long suction tube and 

• in the case of a high suction lift. 

Depending on the circumstances, during the suction 

stroke, the motor speed can be reduced by 75%, 50% or 

25% compared to the normal motor speed during the 

suction stroke. 

The maximum pump capacity is reduced when the anticavitation 

function is selected. 

Maximum capacity limitation 


This function offers the possibility of reducing the 

maximum capacity (MAX. CAP). It influences the functions 

in which the pump is normally operating at 

maximum capacity. Under normal operating conditions, 

the pump cannot operate at a capacity higher than the 

one stated in the display. This does not apply to the 

priming button. 

By means of this function, a large pump can be set to 

act as a much smaller pump. Together with the 1:1000/ 

1:800 capacity range, the purposes of this function are: 

13

14 

Functions 

1. To utilize the smooth and even dosing characteristics 

of the pump at low capacities, to achieve 

– improved chemical mixing, 

– improved dosing through long discharge tubes and 

– improved dosing of high-viscous liquids. 

2. To improve the dosing of gas-containing liquids: In a 

large pump, as compared to a small pump, the displaced 

volume (1) is much larger than the non-displaced 

volume (2). 

2 

Small pump Large pump 

3. To cover several needs with just one pump size. 

4. To adapt the pump to a 4-20 mA signal control with 

4 mA corresponding to 0% and 20 mA to the set 

maximum capacity. 

In this way it is possible for instance to use a DME 48 

for dosing a very small quantity of liquid without 

changing the input signal. See example below. 

Example: 

A DME 48 receives a 12 mA input signal from a control 

instrument, resulting in a 50% output (according to the 

analog curve on page 12) and a capacity of 24 l/h. A 

new situation occurs where it is only necessary to dose 

2 l/h. The maximum capacity limitation is set to 4 l/h. 

The pump is still receiving a 12 mA signal resulting in a 

50% output and a capacity of 2 l/h.

No cap. limitation 

The maximum capacity limitation will also reduce the 

pump speed in timer-based batch control, pulse-based 

batch control and during calibration where the pump is 

usually operating at maximum capacity. 

Calibration 

After start-up, the dosing pumps can be calibrated for 

the actual installation to ensure that the displayed value 

(millilitres or litres) is correct. A calibration program in 

the set-up menu facilitates calibration.

Integrated venting valve 

The DME and DMS dosing pumps are provided with an 

integrated vent valve. The valve makes it very easy to 

prime the pump during start-up: 

The vent valve must be connected to the tank by means 

of a 4/6 mm PVC tubing.

Functions 

The vent valve must be connected to the tank by means 

of a 15/20 mm PVC tubing. 

DME 60-940 l/h 

Switch-mode power supply 


The DME pump is incorporates a switch-mode power 

supply. This makes the pump independent of variations 

in supply voltage and frequency. Operating range: 1 x 

100-240 V, 50-60 Hz. 

Level control 


The pump can be connected to a level control unit for 

monitoring of the chemical level in the tank. 

The pump can react to two level signals. The following 

table shows the pump reactions to the sensor signals: 

Level sensors Pump reaction 

Upper sensor activated 

Vent valve 

• Red indicator light is on. 

• Pump running. 

• Alarm relay activated. 

• Red indicator light is on. 

Lower sensor activated • Pump stopped. 

• Alarm relay activated. 

Applies to control variant AR 

Bus communication 


The pump is available with a built-in module for bus 

communication with GENIbus (variant AG, up to 48 l/h 

only) or PROFIBUS DP (variant AP) systems. These 

modules enable remote monitoring and setting via the 

fieldbus system. 

All DME features are available via bus communication. 

The PROFIBUS GDS-file can be downloaded from 

www.grundfos.com/dosing. 

Diaphragm leakage sensor (60-940 l/h) 

The pump can be fitted with a diaphragm leakage 

sensor. The sensor will detect leakage of the 

diaphragm. The sensor should be connected to the 

drain hole of the pump head. In case of leakage of the 

diaphragm, the signal from the sensor generates an 

alarm in the pump and the alarm relay will be activated.

Functions 

Dosing monitoring 

Applies to all DME and DMS-A(R) (0-48 l/h) 

Dosing stoke measured 

Monitor mounted on suction side 

(DME and DMS) 

The dosing monitor is designed to monitor the dosing of 

liquids which may cause gas accumulation in the 

dosing head, thus stopping the dosing process even if 

the pump is still operating. 

For every measured dosing stroke, the dosing monitor 

gives a pulse signal to the level input so that the pump 

can compare performed pump strokes (from internal 

stroke sensor) with externally measured physical 

strokes (from the dosing monitor). If an external dosing 

stroke is not measured together with the internal dosing 

stroke, this is considered a fault that may have been 

provoked by empty tank or gas in the dosing head. 

When used together with a DME pump, the monitor will 

only operate if it is mounted on the suction side of the 

pump. 

When used together with a DMS pump, the monitor will 

also operate if it is mounted on the discharge side of the 

pump. 

The dosing monitor should be connected to the level 

input (pins 2 and 3). This input must be configured to 

dosing monitoring. Consequently, it cannot be used as 

level input. 

Once the input has been set for dosing monitoring and 

a dosing monitor has been connected and set, the 

dosing monitoring function will be active. 

Definitions: 

• Correct dosing stroke: A pulse from the dosing monitor 

corresponds to the internal stroke signal within 

acceptable time. 

• Incorrect dosing stroke: There is no pulse from the 

dosing monitor corresponding to the internal stroke 

signal within the acceptable time (the pump is not 

pumping). 


Monitor mounted on discharge side 

(DMS only) 


DME and DMS 

Monitor mounted in dosing tube. 

In discharge tube: DMS (in-line) 

In suction tube: DME and DMS (in-line) 

Logic: 

If two incorrect dosing strokes are performed, the pump 

will continue operating, but it will change over to alarm 

mode. The red indicator light will be on and the alarm 

output, if any, will be activated (variant AR). 

For each correct stroke the counter is reset and the 

alarm output, if any, is deactivated. 

Operation in connection with vent valve: 

It is possible to add a self-acting solution for liquids that 

cause gas accumulation by using an automatic vent 

valve. The solution is the dosing monitor with a pump 

and an alarm output (control variant AR). The alarm 

output thus activates the vent valve, which will automatically 

vent gas accumulated in the dosing head. When 

the dosing head has been vented, the pump will start 

pumping again, the alarm output will be deactivated 

and the vent valve will close.

Diaphragm leakage sensor (60 - 940 l/h) 

Optoelectronic leakage sensor to be inserted in the 

drain hole behind the diaphragm for sensing diaphragm 

breakage or leakage. 

The sensor unit consists of: 

• Transmitter receiver 

• Holder for fitting sensor in the drain hole of backplate 

• M12 plug and wire to transmit signal to pump. 

When the liquid gets into contact with the sensor, the 

light refraction changes, causing the sensor to emit a 

signal. 

The signal emitted from the sensor triggers the pump 

to stop dosing and give pump output alarm.

The dosing monitor is used in connection with the 

dosing monitoring function of DME and DMS-A, AR 

pumps. 

The monitor sends a pulse signal (closed contact) for 

every measured dosing stroke. 

As the DME pump will often operate without pulsation 

on the discharge side, the monitor must always be 

installed on the suction side. 

The monitor for a DMS pump can be installed on both 

suction and discharge side. 

Maximum pressure: 10 bar 

Maximum volume: 50 l/h 

Maximum liquid temperature: 35°C 

Maximum liquid viscosity: 20 mPas 

Maximum load of pulse

The flow indicator is used for discharge monitoring. 

When the dosing pump is discharging liquid, the white 

ball will jump in the transparent pipe. Each dosing 

stroke causes a ball jump. The design of the flow indicator 

allows ball movements to be seen at flow rates 

from 0.1 to 45 l/h. 

At a steady flow, the ball will always be in the top position. 

The flow indicator installs and retrofits easily.

Counter-pressure or relief valve 

Adjustable valve for installation in the discharge tube. 

• Installed in-line, the valve functions as a counterpressure 

valve optimising dosing accuracy into systems 

with fluctuating pressure or as anti-siphoning 

valve when dosing into pressureless systems. 

• Installed in a T-connection with the valve outlet connected 

to the tank, the valve functions as a pressure 

relief valve or a safety valve, protecting the pump 

and the discharge tube against excessive pressures. 

Pressure range: 0-10 bar 

Diaphragm material: PTFE.

For the installation in the suction and the discharge 

tube, the pulsation pressure surges, and ensuring a 

steady flow. The dampener is particularly suitable for 

long discharge tubes and/or lines with a small diameter. 

Installed in the discharge tube, the dampener can be 

used for optimising dosing accuracy and for protection 

of pump and discharge line against pressure surges. 

Depending on the system pressure, it may be necessary 

to install a counter-pressure valve after the dampener 

to optimise its function. 

Maximum pressure: 10 bar.

Priming aid 

The priming aid is a transparent, air-tight collector with 

a screw cap on top. It is mounted between the tank and 

the pump. The inlet from the tank and the outlet to the 

pump are both at the bottom of the collector. 

The priming aid is supplied with a bracket for wall 

mounting and a rod for mounting on top of the tank. 

The priming aid has the following functions: 

• Priming. 

The priming aid facilitates priming in case of frequent 

stops and/or high suction lifts by eliminating 

or reducing the dry-suction phase. 

• Gas trap. 

Gas occurring in the suction tube is trapped in the 

top of the priming aid to prevent it from entering the 

dosing head. 

• Pulsation dampening. 

The dampening gas cushion in the top of the priming 

aid reduces pressure surges, resulting in optimum 

dosing accuracy and reduced risk of 

cavitation. 

Material: PVC.

Electric mixers ensure homogeneous mixing of the 

chemical solution in the tank. Mixing is essential for 

dissolving powder additives or liquid additives, which 

are not easily dilutable. 

The mixer is equipped with a single or three-phase 

motor, an mixer shaft connected to the motor shaft and 

a three-blade mixing propeller. 

The selection of the mixer size depends on whether 

readily-soluble substances, or permanently poorly 

miscible emulsions or insoluble suspensions are to be 

stabilised. The latter requires higher power input and, if 

necessary, continuous operation instead of intermittent 

operation. 

The shaft and the propeller must be submerged into the 

liquid during operation. The mixer must be protected 

against dry-running.
