3.4 Principles

nBefore delivery, the manufacturer inspected the dosing pump and

operated it under speciﬁc conditions (with a speciﬁc dosing medium with a speciﬁc density and temperature, with speciﬁc pipe dimensions, etc.) Since these conditions differ at every location of usage, the delivery capacity of the dosing pump should be measured by gauging it at the operating company's installation. For details on the approximate values and the capacity of the dosing pump, refer to the chapter 15 „Delivery characteristic curves“ on page38.

nComply with the information regarding the operating and environmen-

tal conditions (see chapter "Technical data").

nAny restrictions regarding the viscosity, temperature and density of

dosing media must be followed. You must only use dosing media at temperatures above freezing point or below the boiling point of the respective medium.

nThe materials of the dosing pump and hydraulic parts of the system

must be suitable for the dosing medium that is used. In this connection, note that the resistance of these components can change in dependence on the temperature of the media and the operating pressure.

Information on the suitability of materials combined with different dosing media can be found in the Compatibility Chart of Lutz-Jesco GmbH. The information in this resistance list is based on information from the material manufacturers and on expertise obtained by Lutz-Jesco from handling the materials. As the durability of the materials depends on many factors, this list only constitutes initial guidance on selecting material. In all cases, test the equipment with the chemicals you use under operating conditions.

nThe dosing pump is not intended for outdoor use unless appropriate

protective measures have been taken.

nAvoid leaks of liquids and dust into the casing and avoid direct

exposure to sunlight.

nYou must never operate dosing pumps in a potentially explosive

atmosphere if they do not have corresponding nameplates or an appropriate EC Declaration of Conformity for potentially explosive atmospheres.

3.5 Prohibited dosing media

The dosing pump must not be used for these media and substances:

nGaseous media, nradioactive media, nsolid substances, ncombustible media, nall other media that are not suitable for delivery using this dosing

Table 8: Designation of components

4.4 Function description

Dosing pumps are positive displacement pumps. They are used if precisely deﬁned delivery of a medium is necessary. A constant volume per stroke or time is delivered.

The system delivers or meters the dosing medium by means of a repeated sequence of suction strokes followed by pressure strokes. This results in a pulsing ﬂow.

If the dosing pump is in the suction stroke phase, the diaphragm is pulled into the rear ﬁnal position. Due to the resulting vacuum in the dosing head, the pressure valve closes, the suction valve opens and dosing medium ﬂows from the suction line into the dosing head.

If the dosing pump is in the pressure stroke phase, the diaphragm is moved into the front ﬁnal position. Due to the pressure in the dosing head, the suction valve closes and the dosing medium ﬂows through the pressure valve from the dosing head into the pressurised pipe.

7 Installing the Dosing Pump

DANGER

Mortal danger from electric shock!

Electrically conductive liquid can enter pump housings, cable screw connections and mains connectors.

ðMake sure that all protective measures comply at least with the

requirements of protection class IP65.

ðAlways set up the dosing pump such that water cannot enter the

housing.

CAUTION

Danger of personal injury and material damage!

A dosing pump that is difﬁcult to access represents a danger due to incorrect operation and faulty maintenance.

ðInstall the dosing pump such that it is accessible at all times.

7.1 Set up information

When installing, follow the basic principles below:

nThe valves must be vertical: Pressure valve at top, suction valve at

bottom. in this connection, pay attention to the arrow on the dosing head. The dosing head must be aligned such that the arrow points vertically upwards.

nYou should install the dosing pump at a convenient height for

operation.

nIt must not be installed under the ceiling. nThe frame of foundation for ﬁxing the dosing pump must not be

subjected to jolts. The pump must be vibration-free and stable.

nThere must be enough free space in the area of the dosing head and

the suction and pressure valves for these parts to be easily dismantled if required. The entire space requirement for installation and maintenance is approximately 1 m².

nThe distance from the sides of the dosing pump to the wall or other

dosing pumps or equipment must be at least 3 cm. There must be a guaranteed ﬂow of circulating air.

nThe maximum ambient temperature must be complied with, see

chapter 5.2 „Operating conditions and limits“ on page13. If necessary, radiant heat from surrounding equipment must be screened.

nAvoid exposure to direct sunlight. nThe dosing pump is not intended for use out of doors unless

appropriate protective measures have been taken to prevent dust and water from entering the housing.

nFor the dimensions of the fastening holes, refer to chapter 6

„Dimensions“ on page15.

nThe tightening torque for the fastening bolts is 1.5 – 2 Nm.

7.2 Installation examples

7.2.1 Installation on a wall console

Fig. 7: Installation on a wall console

To reduce the structure-borne noise, the dosing pump is bolted to the wall bracket using rubber elements. The materials necessary for this are included with the wall bracket.

7.2.2 Installation on the wall

The dosing pump can be mounted to the ﬂoor or directly to the wall without the need for additional elements. Turn the dosing head appropriately to ensure the ﬂow direction of the medium through the dosing head.

Hydraulic installations

Design of the system

BA-10010-02-V01

Solenoid-diaphragm dosing pump MAGDOS LA / LD Operating instructions

8 Hydraulic installations

In this chapter, you will ﬁnd information about the hydraulic parts of a system that you should install or that can install additionally. In many cases, you must install hydraulic accessories to be able to use all the functions that the dosing pump offers, to guarantee functional safety or to achieve a high level of dosing precision.

WARNING

Caustic burns or other burns through dosing media!

A diaphragm rupture, blocked pressure lines or the use of material not suitable for the dosing medium can result in the discharge of dosing medium. Depending on the type and hazardousness of the dosing medium, this can result in injury.

ðWear the recommended personal protective equipment. ðMake sure that the materials you are using are suitable for the

dosing medium.

ðMake sure that the lubricants, adhesives, sealants, etc. that you

use are suitable for the dosing medium.

ðInstall a leakage drain. ðInstall pressure relief valves.

CAUTION

Danger of personal injury and material damage!

High peak pressures can lead to piping vibrating and cause them to snap. This can result in injury from piping or escaping dosing media.

ðInstall pulsation dampeners.

NOTE

Damage to drives due to overloading

The pressure conditions between the suction and discharge sides must be balanced; otherwise, overloading can result. This can lead to uncontrolled dosing processes, damage to the piping and to the dosing pump.

ðEnsure that the pressure on the discharge side is at least 1 bar

than on the suction side.

NOTE

Locking of threads

Stainless steel and plastic parts (particularly those made of PVC) that are bolted together in a detachable connection (e.g. the dosing head and the valves) can lock. This makes them difﬁcult to release.

ðBefore bolting, grease the corresponding parts with a lubricant

(e.g. PTFE spray). Ensure that the lubricant is compatible with the dosing medium.

8.1 Design of the system

nThe dosing pump s technical data must be taken into account and the

plant s layout must be set up appropriately (e.g. pressure loss when rating the lines with regard to their nominal diameter and length).

nThe entire system and its integrated dosing pump must be designed

in such a way that an escaping dosing medium (due to the failure of wearing parts such as the diaphragm, or burst hoses) does not lead to permanent damage to system parts or the premises.

nThe leakage opening of the dosing head must be visible so that you

can detect a diaphragm rupture. It must be possible for the outﬂow from the leakage drain to be on a free downwards gradient.

nIf you use hazardous dosing media, the installation must be designed

such that no disproportionately high consequential damages arise due to dosing media escaping.

nTo avoid dosing errors after the end of the process, the dosing pump

must be locked hydraulically.

nTo allow you to easily inspect the pressure conditions in the system,

you should provide connections for pressure gauges close to the suction and pressure valves.

8.2 System piping

nThe system piping must not exert any force on the connections and

valves of the dosing pump.

nThis means that steel piping should be connected to the dosing pump

by means of ﬂexible pipe sections.

nThe nominal diameters of the pipework and the installed ﬁttings

should be rated the same as or greater than the nominal diameters of the dosing pump's suction and pressure valves.

nThe suction line should be kept as short as possible. nYou should avoid intertwined hoses. nAvoid loops, since air bubbles can collect.

Aligning the dosing head

BA-10010-02-V01

Solenoid-diaphragm dosing pump MAGDOS LA / LD Operating instructions

8.3 Aligning the dosing head

Fig. 9: Aligning the dosing head

When connecting the dosing lines to the dosing pump, you must observe the direction of through-ﬂow (see arrow 2). The dosing head must be aligned vertically. The alignment can be changed in 90° intervals.

The suction valve (3) must always point downwards. Accordingly, arrow (2) and pressure valve (1) always point upwards. This is irrespective of the positioning of the dosing head to the drive.

8.4 Hydraulic connections

8.4.1 Connecting hose clips

Choose the hose connection according to the condition of the hose (material, inner diameter, wall thickness) in order to ensure maximum pressure resistance.

8.4.1.1 Size 4/6 and 6/9

2. Place a gasket that is suitable for the dosing medium between the connection (5) and the valve.

3. Screw the connecting piece e to the dosing pump's valve using the (2).

4. Thread the union nut (3) and the clamping ring (4) onto the hose.

5. Plug the hose all the way in to the grommet of connection piece.

6. Push the clamping ring onto the grommet of connection piece and

screw it to the union nut.

7. Carry out the same procedure with the connection to the dosing pump's other valve.

üHose clip connected.

8.4.1.2 Size 6/12

Fig. 11: Hose clip 6/12 (internal and external diameter in mm)

Size 6/12 hose clips only have a union nut. It clamps the hose onto the grommet of the connection piece and at the same time fastens on the dosing pump's valve.

Perform the following working steps:

1. Cut the hose (1) to the appropriate length neatly and at an exact right angle.

2. Place a gasket that is suitable for the dosing medium between the connection (4) and the valve.

3. Push the union nut (2) and the cutting ring (3) over the hose.

4. Press the end of the hose onto the grommet of connection piece. You

can do this more easily by moistening the end of the hose on the inside or applying some lubricant to the grommet in the cone area. You should push at least two thirds of the hose onto the grommet of the connection piece.

5. Push the cutting ring over the hose into the cone area on the grommet of connection piece.

6. Screw the union nut onto the valve of the dosing pump.

üHose clip connected.

1. Cut the PVC tube to length.

2. Push the union nut (1) onto the tube.

3. Stick the bonded coupling sleeve (2) to the tube (follow the

instructions of the adhesive manufacturer).

4. Screw the union nut onto the valve of the dosing pump. Use a gasket that is suitable for the dosing medium.

üGlue-in connection made.

8.4.3 Making the cemented connection

Perform the following working steps:

1. Cut the tube to length.

2. Cut the thread (2) onto the end of the tube.

3. Push the union nut (1) onto the tube.

4. Seal the thread. When choosing your sealing material, take into

account its resistance to material, temperature and pressure.

5. Screw the union nut onto the valve of the dosing pump. Use a gasket that is suitable for the dosing medium.

üCemented connection made.

Under normal conditions, you only need to screw the hydraulic connections ﬁnger-tight. However, due to the material settling, the pre-tension of the screw connection can slacken. This means that you must re-tighten the screw connection before carrying out commissioning.

8.5 Connecting a leakage drain

Lutz-Jesco GmbH dosing pumps are produced to the highest of quality standards with a long service life. However, some parts are subject to operational wear. This is the case particularly with the diaphragms that are continuously subjected to forces during the suction and discharge strokes and to the effects of the dosing medium.

If a diaphragm ruptures, the dosing medium starts to leak. This leakage is drained via the leakage opening. On the ﬂange of the dosing head, there are three openings for this purpose. Depending on the alignment of the dosing pump, the leakage is drained via the downward opening.

Fig. 14: Openings of the leakage drain

NOTE

Damage to drives due to effervescent media

If a hose is connected to the leakage drain and it is routed back into the dosing tank, effervescent media can enter the drive and damage it.

ðCollect the leakage in a collecting pan. ðAs an alternative, you can route the leakage back to to the dosing

tank using a funnel. You should install the funnel at an adequate distance from the leakage opening.

8.6 Connecting the dosing head venting facility

MAGDOS LA / LD dosing heads have an integrated dosing head venting facility (except for dosing heads made of stainless steel).

For the procedure when venting, refer to chapter 11.1.1 „Venting the dosing pump“ on page27.

2. Route the other end of the hose into the dosing tank or a collecting

tank.

üDosing head venting facility connected.

8.7 Hydraulic accessories

The following chapter is intended to give you an overview of installation options.

Please note that these operating instructions are no substitute for the instructions supplied with the accessories in each case. The corresponding documentation supplied with the product applies to safety information and provides exact instructions on assembly.

8.7.1 Injection nozzle

If the pressure line enters a main line, it is advisable to install an injection nozzle.

Injection nozzles have three main functions:

nDosing the medium into a main line, nPreventing ﬂowback into the pressure line through a non-return valve.

Notes on assembly:

nDouble-ball injection nozzles must be installed into the main line

vertically from the bottom. You can install hose and spring-loaded injection nozzles any way you like.

nWith dosing media that tend to crystallize, it is advisable to carry out

installation into the main line from the bottom. This prevents air bubbles from being trapped.

nMany dosing media tend to contaminate the injection nozzles, which

can lead to blockages. In cases like this, it is advisable to install an injection nozzle that is easy to dismantle and block off.

8.7.2 Contact-type water meter

The contact-type water meter measures the throughﬂow in a pipe and sends a pulse to the dosing pump, which then starts dosing. This means that ideal proportional dosing is also possible with large throughﬂow ﬂuctuations.

The contact water meter is connected to connection port 2 (see chapter

9.2.2 „Connection socket 3“ on page24).

8.7.3 Pressure-relief valve

Pressure relief valves have an important safety function for protecting the dosing pump and the associated pipes and ﬁttings. The dosing pump can generate a pressure that is many times the rated one. A blocked pressure line can lead to dosing medium escaping.

An improperly high pressure can occur if:

nthe shut-off valves are closed even though the dosing pump is

running,

npipes block.

At an appropriate pressure, a pressure relief valve opens a bypass line and protects the system in this way from damage caused by over-pressure.

Notes on assembly:

nThe line for returning dosing medium from the pressure relief valve

must be routed to the dosing tank or to a collecting pan.

nThe pressure in the dosing tank must not be too high so that it is

possible to accommodate the returned dosing medium.

nAs an alternative, the system can return dosing medium into the

suction line in front of the dosing pump. In this case, there must not be a non-return valve or a foot valve in the suction line.

nYou should install the pressure relief valve as close as possible to the

dosing head.

8.7.4 Back-pressure valve

Back-pressure control valves are necessary if:

nthere are considerably ﬂuctuating system pressures, nthe pressure on the suction side is higher than on the discharge side

or if you intend to carry out dosing into depressurized lines.

In cases like this, if you do not use a back-pressure valve, imprecise dosing results will occur or overloading will result. The back-pressure valve solves these problems by generating a deﬁned, constant backpressure.

In some circumstances, a back-pressure valve is unnecessary if you use a hose injection nozzle and if the backpressure that it generates is adequate.

8.7.5 Pulsation dampener

Pulsation dampeners have the following functions:

nDamping pulsating delivery ﬂows for processes that require

low-pulsation dosing,

nReducing the throughﬂow resistance with long pipelines.

When installed on the suction side:

nDamping of acceleration mass forces and with this reduction of wear

on the dosing pump.

nPreventing cavitation (pull-off of the liquid column) due to too high

acceleration.

However, pulsation dampeners also have important safety functions, since they prevent pressure peaks from arising that lead to piping vibrating and cause them to snap.

This problem can occur:

nwith the high amplitudes of the vibrations, nwhen using long pipes (the severity of the pulsation increases with the

length of the pipe),

nwhen using rigid piping instead of elastic hoses.

Notes on assembly:

nYou should carry out assembly in the direct vicinity of the location

where you want to damp the pressure peaks (directly in front of the suction valve or directly behind the pressure valve).

nPulsation dampeners should be installed with throttle valves or

back-pressure valves installed directly behind them. By setting the valves appropriately, you can further-optimise damping of the

Hydraulic installations

Hydraulic accessories

BA-10010-02-V01

Solenoid-diaphragm dosing pump MAGDOS LA / LD Operating instructions

pulsations.

nTo prevent unnecessary pipe friction losses, you should lay the

connecting line straight and in accordance with the rated width of the pulsation dampener.

nYou must separately fasten relatively large pulsation dampeners and

ones with hose connections.

nPipelines must not transfer any mechanical tensions onto the

pulsation dampener.

8.7.6 Priming aid

Priming aids are particularly advisable:

nin the case of dosing pumps with small volumetric displacements per

stroke or with low stroke length settings,

nwith high suction hights, nwith highly dense dosing media, nat priming for the ﬁrst time due to dry valves and air in the suction line

and the dosing head,

nin dosing systems with frequent downtimes.

Further advantages resulting from priming aids:

npreventing cavitation in the suction line, ngas removal, noptical dosing control with small amounts, nsmoothing of the suction ﬂow.

8.7.7 Level monitoring

Level monitoring of suction-side feeding of the dosing medium to prevent the tank being sucked dry and to ensure that it can be topped up again in good time.

8.7.8 Dosing of suspensions

When dosing suspensions, the dosing head must be rinsed regularly to prevent depositing. To do this, you install a feed line for the rinsing medium (water) in the suction side installation.

8.7.9 Suction pressure regulator

A suction pressure regulator may be necessary if the suction-side installation of the system demonstrates a varying suction pressure or supply pressure:

nDosing pumps that are installed above dosing tanks deliver less as the

tank empties, since the suction head increases.

nDosing pumps that are installed below dosing tanks deliver less as the

tank empties, since the positive delivery pressure reduces.

Further problems that can occur:

nGreater wear on the dosing pump, e.g. diaphragm rupture due to the

effects of heavy forces with particularly high tanks and high-density dosing media.

nIdling of the dosing tank in the case of a diaphragm rupture or pipe

breakage.

nImpermissibly high forces in the pump transmission that occur when

dosing pumps receive the dosing medium directly from the pressure line.

nReduced performance or destruction of ﬁttings due to cavitation with

long suction lines.

Installing a suction pressure regulator is a remedy for the problems above. The suction pressure regulator is opened by the dosing pump's suction pressure. This ensures that no dosing medium can ﬂow if the dosing pump is not running or no vacuum can be generated following a pipe fracture.

DANGER

Mortal danger from electric shock!

If there is an electrical accident, you must disconnect the dosing pump from the mains as quickly as possible.

ðInstall an emergency stop switch or integrate the dosing pump

into the plant safety concept.

CAUTION

Danger of automatic start up!

The dosing pump does not have an ON/OFF switch and may start to pump as soon as it is connected to the mains supply. This means that dosing medium can escape. Depending on the type and hazardousness of the dosing medium, this can result in damage to property or to injury.

ðInstall an emergency stop switch or integrate the dosing pump

into the plant safety concept.

NOTE

Damage due to incorrect mains voltage

The dosing pump can be damaged if you connect it to the wrong mains voltage.

ðObserve the information on the mains supply that is given on

the rating plate.

NOTE

Insufﬁcient electromagnetic compatibility

When you connect the dosing pump to a socket without an attached protective earth, it is not possible to guarantee the interference radiation and interference immunity according to EMC regulations.

ðOnly connect the dosing pump to sockets with an attached

protective earth.

9.1 Principles

nThe dosing pump is ﬁtted with a 115 V AC or 230 V AC (50 / 60 Hz)

power supply unit.

nThe electrical connection comply with local regulations. nThe dosing pump must be plugged into a grounded power outlet. nTo avoid dosing errors at the end of the process, the dosing pump

must be locked electrically.

nThe dosing pump must not be operated by switching the mains

voltage on or off.

nSignal cables must not be laid parallel to high-voltage current lines or

mains cables. You must route supply and signal lines in separate channels. An angle of 90° is required at line crossings.

NOTE

Conducting rubber hoses with versions LA and LD

The MAGDOS LA and LD are delivered with two conductive rubber hoses installed in connection sockets 1 and 3. These conduct electricity and ensure that the contacts in the connection sockets remain closed when no cables are connected. If the conductive rubber bands in connection sockets 1 and 3 are missing or not correctly installed and there are no cables connected to the sockets, it is not possible to start the dosing pump.

ðInsert the conductive rubber bands in connection sockets 1 and

3 if there are no cables connected to the connection sockets.

ðEnsure that the conductive rubber band is installed on the

correct contacts (see instructions in following chapters).

ðRetain the conductive rubber hoses so that you can change the

assignment of the connection ports later.

After connecting the mains supply, residual dosing media in the dosing head can spray out.

ðBefore connecting the mains supply, connect the dosing lines. ðCheck that all the screw connections have been tightened

correctly and are leak-proof.

CAUTION

Danger of automatic start up!

ðStop the dosing pump before disconnecting it from the mains

supply.

ðEnsure that the dosing pump has been installed correctly before

connecting it to the mains supply.

11.1 Commissioning the dosing pump

Precondition for action:

üThe dosing pump was ﬁtted and installed in accordance with the sec-

tions “Fitting the dosing pump”, “Hydraulic installation” and “Electrical installation”.

üAll the mechanical fastenings have been inspected to ensure

adequate load-bearing capacity.

üThe dosing head screws have been tightened with the correct torque. üAll the hydraulic sections have been inspected to ensure they are

adequately leak-proof and that the through ﬂow direction is correct.

For initial commissioning, it is advisable to use water as the dosing medium to check that the system is leak-proof and that the dosing pump is functioning correctly. Check ﬁrst whether undesirable reactions could occur between the actual dosing medium and the water.

Perform the following working steps:

1. Open the shut-off valves on the suction and discharge sides if present.

2. Plug in the dosing pump's mains plug to the power supply.

3. If the dosing head is ﬁtted with a vent screw, vent the dosing pump

(see section 11.1.1 „Venting the dosing pump“ on page27).

4. Select an operating mode and start the dosing pump in accordance with the instructions in the chapter 11.2 „Operating modes“ on page28.

4The dosing pump primes. If it does not prime enough, use a priming

aid (see chapter 8.7.6 „Priming aid“ on page21).

At initial commissioning, it is advisable to prime the pump without backpressure. For this purpose, we recommend installing a relief valve on the discharge side of the dosing pump.

üThe dosing pump is commissioned.

11.1.1 Venting the dosing pump

Plastic dosing heads are ﬁtted with a vent screw. Gas bubbles can be removed from the dosing head using vent screws, in order to improve the performance of the pump. Whether venting is helpful depends on the dosing medium and the size of the pump.

Table 25: Examples for transmission / reduction of pulse signals

With sequences consisting of successive pulses, it is necessary to ensure that given speciﬁc settings, the pulses are not always followed by the number of dosing strokes which correspond to the pulses. This is due to the circumstance that only one whole dosing stroke is performed, and not e.g. half or a quarter of a dosing stroke. Depending on the transmission or reduction factor and the number of pulses, however, there is a possibility of uneven results with "pending" pulse signals. In theses cases, the required number of dosing strokes is only achieved after a number of pulse cycles.

Examples:

The dosing pump receives pulses with a reduction factor of 30%. For the ﬁrst stroke, it requires 4 pulses in this setting (4x30% = 120%), as 3 pulses (3 x 30% = 90%) are insufﬁcient for one dosing stroke (= 100%). However, the second dosing stroke is executed after just 3 more pulses, as the stroke buffer of the dosing pump still has 20% pending from the ﬁrst 4 pulses (120% - 100% = 20%) and this is added to the 3 pulses (90% + 20% = 110%). The third dosing stroke also only requires 3 additional pulses (90% + 10% = 100%). A further 4 pulses are then required for the fourth dosing stroke.

If pulses are transferred to the dosing pump with a transmission factor of 125%, a dosing stroke is executed for each of the ﬁrst 3 pulses. With the 4th pulse, it executes 2 dosing strokes (3x 25% pending from the ﬁrst 3 pulses + 125% = 200%).

The dosing pump has a dynamic stroke buffer which includes the interval between the pulses in the calculation and adjusts the distribution of the dosing strokes accordingly.

11.2.2.4 Calculating the transmission factor

The dosing pump MAGDOS LD has a deﬁned stroke volume per dosing stroke. If a certain dosing quantity is required per pulse, the corresponding transmission factor can be calculated for the external operating mode.

You can ﬁnd a simple means of performing the necessary calculations on the Lutz-Jesco GmbH homepage. To do so, click on the following link or enter it in your browser: http://www.lutz-jesco.com/en/online-help

If you have no Internet connection, you can also perform the calculation yourself.

The following parameters are required for this:

nrequired dosing quantity in ml/pulse ndelivery capacity of the dosing pump in ml/stroke

The delivery capacity of the dosing pump can be taken from in the technical data and the delivery characteristic curves (see “delivery capacity data” on page 13 and “delivery characteristic curves” on page

46). Intermediate values can be interpolated.

Calculate the value using the following formula:

required dosing quantity per pulse x 100%

delivery capacity per stroke

Example: With a MAGDOS LD 6, 1 ml should be proportionally dosed per pulse. The stroke volume at 4 bar is 0.63 ml.

The factor to be set is calculated as follows:

required dosing quantity per pulse x 100%

delivery capacity per stroke

1 ml/pulse x 100

0,63 ml/stroke

= 159 %

In this example, the pump would execute 159 strokes for 100 incoming pulses.

Note that the stroke frequency of the dosing pump is restricted. For the MAGDOS LD 6, the max. stroke frequency is approx. 180 strokes/min. Any additional incoming strokes are not processed. For this example, this means that the dosing pump can process a maximum of 113 pulses/min (180/1.59).

11.2.2.5 Starting the dosing pump

Precondition for action:

üThe dosing pump has been connected in accordance with the

chapter “Pulse input (only LD)” on page 24.

1. Press Start.

2. Supply pulses to the pulse input of the dosing pump.

üDosing pump has started.

11.2.2.6 Stopping the dosing pump

èStop the incoming pulses or press Stop.

üDosing pump has stopped.

11.2.2.7 Operation with contact water meter (only LD)

The dosing pump MAGDOS LD is prepared for operation with a contact-type water meter. The contact sequence of the water meter and the size of the dosing pump must be matched to each other (calibrated).

You can ﬁnd a simple means of performing the necessary calculations on the Lutz-Jesco GmbH homepage. Visit us under: http://www.lutz-jesco.com/online-helfer

If you have no Internet connection, you can also perform the calculation yourself.

Preselection of the dosing pump size

You can use the following diagram to determine the necessary size of the dosing pump depending on the intended dosing quantity and the existing or selected pulse sequence of the contact-type water meter. Comparison with the technical data of the dosing pump with regards to the operating pressure is also necessary (see “Technical data” on page 13). ).

Solenoid-diaphragm dosing pump MAGDOS LA / LD Operating instructions

Calculating the transmission factor

The ﬁrst calculation phase is used to determine the transmission factor which is set in the display of the MAGDOS LD.

The following parameters are required for this:

nDosing quantity per cubic metre of water in ml/m3 nPulse sequence of water meter in l/lmp nDelivery capacity per stroke of the dosing pump in ml/stroke

Calculate the factor using the following formula:

required dosing quantity per pulse x 100%

delivery capacity per stroke

1 ml/pulse x 100

0,63 ml/stroke

= 159 %

required dosing quantity x pulse sequence of water meter

delivery capacity per stroke x 10

Example:

1000 ml of a dosing medium should be dosed per m3 of water in a water line at 4 bar. The contact-type water meter has an pulse sequence of 1 l/ pulse. The selection table (see 30) can be used to select a MAGDOS LD 6 with 0.63 ml/stroke at 4 bar. A MAGDOS LD 10 would also come into consideration as it doses 0.88 ml/stroke. A MAGDOS LD 15 is not suitable as it can only work at 3 bar.

The factor to be set is calculated as follows:

1 ml/pulse x 100

0,63 ml/stroke

= 159 %

1000 x 1

0,63 x 10

= 159 %

Calculating the necessary stroke frequency

The second calculation phase checks the size of the contact-type water meter and the maximum stroke frequency of the MAGDOS LD by comparing the required stroke frequency and the maximum stroke frequency of the dosing pump.

The following additional parameter is required for this:

nThe nominal size of the contact-type water meter in cubic metres per

hour [m³/h]

Calculate the necessary stroke frequency using the following formula:

required dosing quantity per pulse x 100%

delivery capacity per stroke

1 ml/pulse x 100

0,63 ml/stroke

= 159 %

required dosing quantity x pulse sequence of water meter

delivery capacity per stroke x 10

1000 x 1

0,63 x 10

= 159 %

dosing quantity in ml/m³ x nominal size of the water meter in m³/h

delivery capacity per stroke in ml/stroke

Example:

For the dosing speciﬁed above, a contact-type water meter with the nominal size of m³/h should be used.

The necessary stroke frequency is calculated with:

required dosing quantity per pulse x 100%

delivery capacity per stroke

1 ml/pulse x 100

0,63 ml/stroke

= 159 %

delivery capacity per stroke x 10

1000 x 1

0,63 x 10

= 159 %

delivery capacity per stroke in ml/stroke

1000 ml/m³ x 5 m³/h

0,63 ml/stroke

= 7937 strokes/h

This value is compared with the maximum possible stroke frequency of the dosing pump. The MAGDOS LD 6 achieves a maximum of 10800 strokes/hour.

Result:

The required stroke frequency must be smaller than the maximum stroke frequency of the dosing pump, which is the case here.

If the maximum stroke frequency is higher, the dosing pump cannot continue up to the water meter's maximum ﬂow rate. In this case, the following versions are possible:

nUse of a higher dosing pump model, e.g., MAGDOS LD 10 instead of

MAGDOS LD 6

nReduction of the dosing quantity via higher concentration of the

dosing medium

nIncrease of the pulse sequence of the contact-type water meter, e.g.,

0.5 l/pulse instead of 1 l/pulse

15 Delivery characteristic curves

This Chapter is intended to give you an idea of the delivery capacity that the dosing pump can achieve at speciﬁc back pressures. These delivery capacities were determined on the manufacturer's test stands. They apply at 20 °C (68 °F) for water, at 100% stroke frequency. The delivery capacity depends on the medium (density and viscosity) and temperature. Since these conditions vary at every installation location, you should calibrate the dosing pump.
