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 discharge 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 discharge valve from the dosing head into the pressurised pipe.

4.6 Conveying characteristics
The design of the dosing pump enables it to perform the pressure and suction stroke at different speeds. For low supply rates, for example, the dosing pump performs the suction stroke at the maximum speed and adjusts the speed of the pressure stroke to match the desired supply rate. This produces a constant supply stream, which gives you a low-pulsation, smooth dosing.

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.

7.2 Installation examples 7.2.1 Installation on a wall console

Operating instructions

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.
Especially the oil level glass, the oil inlet and the oil drain.
7.1 Set up information
When installing, follow the basic principles below:
n The valves must be vertical: Discharge 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 discharge 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.

Fig. 10: 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

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

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 pumps technical data (see chapter 5 ,,Technical data” on page 13) 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 discharge valves.

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.

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 discharge 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.

Operating instructions

8.5 Connecting a leakage drain

8.6 Connecting the dosing head venting facility

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.

The dosing heads of the MEMDOS SMART LB / LD 2, 5 and 10 have an integrated dosing head venting unit (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 30.

Fig. 17: Openings of the leakage drain

Fig. 18: Dosing head venting facility with hose connection
Perform the following working steps:
1. Connect a 4/6 hose to the dosing head venting facility. 2. Route the other end of the hose into the dosing tank or a collecting
tank.
ü Dosing head venting facility connected.

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.

8.7 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.

Hydraulic installations 21
Hydraulic accessories

Stepper motor-driven diaphragm dosing pump MEMDOS SMART LB / LD

Operating instructions

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 2″ on page 25).
The ratio of throughflow to executed strokes of the dosing pump is determined in “Pulse input” mode (see chapter “Water meter” 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 discharge 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 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
Only for LD: 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.

Hydraulic accessories

BA-10110-02-V01

Stepper motor-driven diaphragm dosing pump MEMDOS SMART LB / LD
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.
Notes on assembly:
n When using a large suction pressure regulator, you should provide a pulsation dampener on the suction side.

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. 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.

9.1 Principles
n The dosing pump has a 110 240 V AC 50/60 Hz wide-range 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
Compromised functions due to open contacts
The dosing pump is supplied with conductive rubber bands installed in the connection ports 1 (LB) or 1 and 3 (LD). The conductive rubber bands 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 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 if you do
not wire up the connection sockets. ð Ensure that the conductive rubber bands are installed on the
correct contacts (see instructions in following section).

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.

Operating instructions

11.2.2.2 Setting the transmission and reduction
The transmission and reduction factors can be set in 1% intervals of 1% to 1000%. A set value of 100% means that the dosing pump executes one dosing stroke per incoming pulse signal. For values above 100%, the dosing pump executes more dosing strokes per pulse signal accordingly. For values below 100%, the dosing pump executes less than one dosing stroke per pulse signal, meaning that several pulse signals are required before a dosing stroke is executed. The number of pulse signals required for a dosing stroke is displayed on the dosing pump display for values below 100%.
50% (2)

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.
11.2.2.3 Calculating the transmission factor
The dosing pump MEMDOS SMART 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.

Table 27: Examples for transmission / reduction of pulse signals

In cases of sequences of sequential pulses, it must be noted that the number of dosing strokes corresponding to the pulses does not always follow the pulses immediately in certain settings. This is due to the fact that only entire dosing strokes are executed, e.g. not half or quarter dosing strokes. 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%).
