Liquid End

6.1

The dosing process is performed as follows: The diaphragm is pressed into the dosing head; the pressure in the dosing head closes the suction valve and the feed chemical flows through the discharge valve out of the dosing head. The diaphragm is now drawn out of the dosing head; the dis‐ charge valve closes due to the negative pressure in the dosing head and fresh feed chemical flows through the suction valve into the dosing head. One cycle is completed.

6.2 Drive unit

The displacement body is driven by an electromagnet, which is controlled by an electronic control.

optoDrive® drive technology

Fig. 6: Metering types: a) pulsing, b) nearly continuous

The optoDrive® drive technology means the variation over time of the metering flow can be precisely matched to the requirements of the partic‐ ular application. Hence the user can, dependent on requirements, set a slow discharge stroke for nearly continuous metering or a quick stroke e.g. for quick clocked filling processes. In both operating modes it is possible, to selectively also slow the suction stroke, see figure. In this way, it is pos‐ sible to prevent the main cause for imprecise metering with high viscosity feed chemicals, namely the incomplete filling of the liquid end. For the case of gaseous feed chemicals, the slow suction stroke prevents cavita‐ tion and consequently increases metering accuracy. Oscillations in the back pressure in the metering line, which could lead to undesirable varia‐ tions in the metering volume, are automatically compensated for by the drive. Consequently, a dosing precision is attained, which otherwise could only be achieved using a complex control circuit.

p Pressure t Time

The integral injection point monitoring of the hydraulic metering parame‐ ters, optoGuard® is integrated in the drive. It automatically detects blocked points of injection or broken metering lines. Consequently, dependent on the hydraulic installation situation, separate relief valves and pressure sen‐ sors need not be used, and no uncontrolled metering through a broken line occurs. It also detects air or gases (airlock) trapped in the liquid end. This prevents metering of incorrect quantities and thus increases process reliability. The relevant messages are shown on the pump's display. The system operator can determine, depending on the type of fault, whether a message is to be sent to the process control system via the fault signal relay and whether metering is automatically stopped.

6.3

Capacity

The capacity is determined by the stroke length and rate.

"Calibrate" function

The stroke rate is set manually via the control unit.

This operating mode provides the option of working with large transfer fac‐ tors (up to 65535). Metering can be triggered by pressing the button by a pulse received via the "External control" jack through a contact or a semiconductor switching element. A metering volume (batch) or a number of strokes can be selected in the

This operating mode offers the option of activating the pump externally by means of potential-free contacts (e.g. by means of a contact water gauge). The number of strokes (reducing or transfer factor 0.01 to 99.99) can be pre-selected in the

The stroke rate is controlled using an analog current signal via the "External control" jack. Processing of the current signal can be preselected via the control unit.

The following functions can be selected vin the menu

The stroke rate is controlled using an analog current signal via the "External control" jack. Processing of the current signal can be preselected via the control unit.

The pump can also be operated in the calibrated state in all operating modes. The corresponding continuous displays can then either display the metering volume or the capacity (in the 2nd level continuous display). The calibration remains valid over the entire stroke rate range and over a stroke length range from 0 - 100 %.

Functional and fault Indicator

This combined relay can generate a contact with each stroke via its pacing relay in addition to its function as a fault indicating relay.

The relay can be retrofitted through a knock-out opening in the pump foot refer to "Retrofitting relays".

The function "Bleeding" is used for controlled bleeding of the liquid end, if the pump is provided with the option "Automatic bleed". The "Automatic bleed" option can be retrofitted, i.a. via a knock-out in the control unit.

There are two versions:

n version with only 1 relay - to control the bleed valve. n Version with only 2 relays - one relay to control the bleed valve and

one relay free for other uses.

The I signal of the current output signals the currently calculated pump metering volume. The option "mA output" can be retrofitted via a knock-out in the control unit.

The option additionally always provides a fault indicating relay or a pacing relay.

The operating and fault statuses are indicated by the three LED indicators and the "Fault" identifier of the LCD screen, see also the "Troubleshooting" chapter.

Hierarchy of operating modes, functions and fault statuses

The warning indicator lights up if the fluid level in the chemical feed con‐ tainer falls below the first switching point of the level switch.

The operating indicator lights up if the pump is ready for operation and there are no fault or warning alerts. It goes out quickly as soon as the pump has performed a stroke. It starts to flash as soon as the stroke rate falls below 30 strokes / min.

The different operating modes, functions and fault statuses have a dif‐ ferent effect on if and how the pump reacts.

The following list shows the order:

1. - Priming

2. - Fault, Stop, Pause

3. - Auxiliary rate

4. - Manual, Analog, Contact, Batch

Comments:

re 1 - "Priming" can take place in any mode of the pump (providing it is

functioning).

re 2 - "Fault", "Stop" and "Pause" stop everything apart from "Priming".

re 3 - The stroke rate of "Auxiliary rate" always has priority over the

stroke rate specified by an operating mode or priority 4.

The number of received pulses, which could not yet be processed, is stored by the pump in the stroke memory.

CAUTION! When changing over from the "Manual" operating mode

to the "Batch" operating mode, the pump maintains the stroke rate.

The stroke rate can also be set in ‘Contact’ operating mode. It should normally be set to 200 strokes / min.

In operation, the batch size can be changed more easily by using ‘Batch size’ in the continuous display:

Additionally, you can activate the "Memory" function extension (Identifier "m"). When "Memory" is activated, the pump adds up the remaining strokes , which could not be processed, up to the maximum capacity of the stroke memory of 65,535 strokes. If this maximum capacity is exceeded, the pump goes into fault mode.

The number of strokes per pulse depends on the factor which you can input. By using a factor you can multiply incoming pulses by a factor between 1.01 and 99.99 or reduce them by a factor of 0.01 to 0.99:

Tab. 4: ** Explanation of step-down

With a factor of 1 ... 1 stroke is executed per 1 pulse.

With a factor of 0.5 ...1 stroke is executed after 2 pulses.

With a factor of 0.1 ...1 stroke is executed after 10 pulses.

With a factor of 0.75 ...1 stroke is executed once after 2 pulses,

then 1 stroke is executed twice after 1 pulse,

and then again 1 stroke after 2 pulses etc.

If a remainder is obtained when dividing by the factor, then the unit adds the remainders together. As soon as this sum reaches or exceeds "1", the pump executes an additional stroke. Therefore on average during the metering operation, the resultant number of strokes pre‐ cisely matches the factor.

Non-processed pulses

The number of received pulses, which could not yet be processed, is stored by the pump in the stroke memory. When the pressed or the "Pause" function is activated, the stroke memory is deleted. You can avoid this with the "Memory" function extension:

You can select three types of current signal processing:

‘0 - 20 mA’

‘4 - 20 mA’

‘Curve’

At 0 mA the pump is stationary –

At 20 mA the pump works at maximum stroke rate.

Between these values, the stroke rate is proportional to the current signal.

4 - 20 mA

At 4 mA the pump is stationary –

At 20 mA the pump works at maximum stroke rate.

Between these values, the stroke rate is proportional to the current signal.

With current signals of less than 3.8 mA, an error message appears and the pump stops (e.g. if a cable has broken).

The maximum stroke rate can only be reduced in pro‐ cessing mode ‘Curve’ , not in processing modes "0 .. 20“ and “4 .. 20“.

The slowing of the discharge stroke only becomes noticeable at lower stroke rates.

–

At maximum stroke rate, ‘slow’ is identical to ‘fast’ !

–

Slowing of the suction stroke leads to a lower capacity.

Suction stroke

In both metering modes it is possible, to selectively also slow the suction stroke. For the case of gaseous feed chemicals, the slow suction stroke prevents cavitation and consequently increases metering precision ( b) and c) ). In this way, it is possible to prevent the main cause of inaccurate metering with high viscosity feed chemicals, namely the incomplete filling of the liquid end.

Fig. 29: Pulsed and quasi-continuous operation with:

a) normal suction stroke b) slightly delayed suction stroke c) maximum delayed suction stroke

The metering behaviour of the pump can be matched to the viscosity of the feed chemical.

Sequence of the bleed procedure (auto‐ matic):

1. The pump control stops the running normal metering operation - the "Stop" symbol appears on the LCD screen.

2. After 1 s, it opens the bleed valve of the liquid end (via the bleed relay and the solenoid valve).

3. 1 s later, the pump starts to run at its maximum possible stroke rate (as during priming) - the symbol "Airlock" appears on the LCD screen instead of the "Stop" symbol.

4. The pump operates in this way for the total set time.

5. Once the set time has elapsed, the pump stops, the symbol "Stop" appears on the LCD screen again.

6. After 1 s the pump control closes the liquid end bleed valve.

7. After 1 s the "Stop" symbol disappears and the pump recommences normal operation.

If the pump was in the "Stop" state upon triggering (Key pause, error), the start of the bleed procedure is delayed - until this state is cleared.

If the pump switched to "Stop" state during the bleed procedure, the pump control jumps immediately to phases 5 and 6. (see above) This definitely cancels the bleed procedure. As soon as the "Stop" state is cleared, the bleed procedure starts from the beginning.

In the "Stop" or "Pause" states (either because of a fault or operation) or "Pause" the current output emits a current of 4 mA.

The signal for the current, calculated capacity "Litre / h *" is calculated by the pump according to the following formula (here for the range 4-20 mA):

Warning of faulty operation Refer to the exploded drawings in the appendix when

working on the unit.

Warning of faulty operation

–

Discharge and suction valves differ from each other! Only take them apart one after each other, so that you do not confuse the components!

–

Only use new components which fit your valve, both in terms of shape and chemical resistance!

–

Readjust the pump after replacing a valve!

–

Using an Allen key or similar, insert it into the smaller hole of the pressure connector and push the valve inserts out of it.

Cleaning a suction valve for types 0730, 1020, 1612, 1608, 2508

Cleaning a discharge valve for types 0280, 0450

A suction valve is constructed in almost the same way as a discharge valve.

Please note, however, that:

n the two valve inserts are identical here. n There is an additional spacer between the valve inserts. n There is a shaped seal in the dosing head instead of an O-ring. n The flow direction of the suction connector is the opposite to that of

the pressure connector.

–

Discharge and suction valves differ from each other! Only take them apart one after each other, so that you do not confuse the components!

–

Only use new components which fit your valve (both in terms of shape and chemical resistance)!

–

With the PVT material version, the ball seat is inte‐ grated in the dosing head and so has to be cleaned separately!

–

With the PVT material version, the discharge valve is a double ball valve!

–

Using an Allen key or similar, insert it into the smaller hole of the pressure connector and push the valve inserts out of it.

WARNING! A few cubic centimetres of feed chemical may have

accumulated behind the metering diaphragm in the backplate following a leak - depending on the design!

– Take this feed chemical into consideration when you

are planning a repair - especially if it is hazardous!

Personnel:

Technical personnel

n If necessary take protective measures. n Adhere to the material safety data sheet for the feed chemical. n Ensure that the system is at atmospheric pressure.

1. Empty the liquid end (turn the liquid end upside down and allow the feed chemical to run out; flush out with a suitable medium; flush the liquid end thoroughly when using hazardous feed chemicals!)

2. Turn the stroke adjustment dial up to the stop below 0% stroke length if the pump is running (the drive axle is then difficult to turn).

3. Switch off the pump.

4. Unscrew the hydraulic connectors on the discharge and suction side.

5. With types with coarse/fine bleed valve: Firstly remove the coarse/ fine bleed valve (grip), then lift off the cover of the liquid end with a screwdriver.

6. Remove the screws (1).

7. Remove the dosing head (2) plus screws (1) from the pump - see figure Fig. 32

8. Replace the dosing head (2) and screws - the screws (1) should still extend into the holes in the diaphragm (3), but not into the pump housing!

9. Hold the pump housing (6) with one hand and clamp the diaphragm (3) with the other hand between the dosing head (2) and the back‐ plate (4).

10. Loosen the diaphragm (3) from the drive axle with a gentle back‐ wards turn of the dosing head (2), diaphragm (3) and backplate (4) in an anticlockwise direction.

11. Pull the dosing head (2) with the screws (1) out of the diaphragm (3) and completely unscrew this from the drive axle.

12. Remove the backplate (4) from the pump housing (6).

13. Check the condition of the safety diaphragm (5) and replace if nec‐ essary.

14. Push the safety diaphragm (5) onto the drive axle only until it lies flush with the pump housing (6) and no further!

15. Tentatively screw the new diaphragm (3) onto the drive axle up to the stop - ensure that this is successful, otherwise the pump will subsequently not meter correctly!

16. Check whether the diaphragm holes align correctly with the pump housing.

17. If not, start the pump and adjust the stroke length to 100%.

18. With the pump running, slowly turn the diaphragm (3) in the clock‐ wise direction until the 4 diaphragm holes align correctly with the pump housing (6). Do not turn anticlockwise!

19. Clamp the diaphragm (3) in this position, adjust the stroke length to 0% and stop the pump.

20. Unscrew the diaphragm (3) again.

21. Place the backplate (4) onto the pump housing (6).

CAUTION! – Make sure that the leakage hole points down‐

wards when the pump is subsequently fitted see figure in the "Maintenance" chapter!

Place the backplate (4) immediately into the

–

correct position on the pump housing (6)! Do not twist the backplate on the pump housing to prevent the safety diaphragm (5) from becoming warped!

22. Place the diaphragm (3) into the backplate (4).

CAUTION! – Do not over-tighten the diaphragm (3) in the

following step!

– Ensure that the backplate (4) remains in its

position so that the safety diaphragm does not become warped!

23. Hold the backplate (4) firmly and screw the diaphragm (3) in a clock‐ wise direction until it is sitting tightly (the twisting resistance of the return spring can be felt).

24. Place the dosing head (2) with the screws (1) onto the diaphragm (3) and the backplate (4) - ensure that the suction connector points downwards when the pump is in its subsequent fitting position.

25. Gently tighten the screws (1) and then tighten them diagonally. See below for the tightening torque.

26. With types with coarse/fine bleed valve: Allow the cover of the liquid end to rest in the dosing head, then press the grip of the bleed valve into the coarse/fine bleed valve.

Check the tightening torque of the screws after 24 hours of operation!

13.3 Cleaning the Diaphragm Rupture Indicator

WARNING! Warning of unnoticed escape of feed chemical After triggering of the diaphragm rupture indicator, any

feed chemical residues can be blocked.

– After the diaphragm rupture indicator has been trig‐

gered, clean and test it.

Personnel:

1. First replace the liquid end diaphragm - see above!

2. Unscrew the diaphragm rupture indicator using an SW 15 openended spanner.

3. Clean the diaphragm rupture indicator with suitable liquid - if pos‐ sible using water (polysulphone material).

4. Test the connected diaphragm rupture indicator: Immerse the for‐ ward hemisphere completely in water, a diaphragm rupture must be indicated in the continuous display.

The continuous display indicates a diaphragm rupture.

5. Thoroughly dry the diaphragm rupture indicator.
