WARNING

Poisoning and caustic burns

If corrosive, poisonous, ionising or biological media come into contact with skin, eyes and the respiratory tract they may cause serious injuries

➢ Observe the safety data sheets for the media to be trans-

ferred

➢ Use personal protective equipment ➢ Operate the pump in a suitably protected area ➢ Check the resistance of any parts which come into con-

tact with the fluid (see chemical resistance list or consult your local KNF dealer)

WARNING

Poisoning and caustic burns caused by bromine

Contact with skin, eyes and the respiratory tract causes serious injuries and ulcers

➢ Never transfer bromine

WARNING

Damage caused by ionising radiation

Radioactive materials cause serious damage to health and reduce the service life of the pump.

➢ Decontaminate the pump ➢ Wear personal protective equipment ➢ Mark the pump

NOTE

If it cannot be ensured that the transferred medium is free of solids, a < 70 µm filter with a sufficiently large filter area must be fitted upstream of the pump to prevent it from being damaged (see Chapter 13)

Using the fluid type setting "Visc500cSt" allows media with a viscosity of

500 cSt to be transferred at a limited flow rate. (see Section 7.11)

Applies to water and low-reactivity media. For aggressive media, re-

sistance is to be checked at a higher medium temperature.

Operating instructions SIMDOS10 EN Technical data

KNF Flodos BA_SIMDOS10_EN_05_167721.docx Translation of original operating instructions, English 21

NOTE

Before using a medium, check the compatibility of the materials of the pump head, pump housing, diaphragm and valves with the medium.

➢ Check resistance, see chemical resistance list and Sec-

tion 4.3

➢ Clarify resistance with KNF (see last page)

3.14 Accuracy/ reproducibility

The accuracy of the metering pump is appropriately characterised by the maximum absolute error A and the maximum relative error B:

 max. inaccuracy ≤ A + B

Error

Value

Absolute error A

≤ ± 1‰ nominal value

Relative error B

≤ ±1.9% of setting value

Max. deviation

≤ A+B

Mean accuracy

+/- 2%

Mean reproducibility4

+/- 1%

Tab. 12: Error A and error B

SIMDOS 10, nominal value of 100ml/min For a setting of 20ml/min, the accuracy should therefore be within

the following error limits: Deviation ≤ (±1‰ x 100ml/min) + (±1.9% x 20ml/min) ≤ (±0.1ml/min) + (±0.38ml/min) ≤ ±0.48ml/min ≈ ±2% of setting value

NOTE

Greater inaccuracies may occur for fluids with a viscosity of > 150 cSt or with a tendency to gassing out

➢ Set "fluid type" (see Section 7.11) ➢ Calibrate the pump in the system (see Section 7.12)

NOTE

The flow rate may differ from the calibrated value for some applications, according to the medium, its viscosity, density and temperature, pressure and installation type (e.g. cross-section constrictions)

➢ For accurate metering, calibrate the metering pump in the

system (see Section 7.12)

Under constant environmental conditions and with the same hose con-

The diaphragm liquid pumps are based on reciprocating displacement pump technology. The elastic diaphragm (4) is moved up and down by the eccentric (5) and the connecting rod (6). In the downward stroke it aspirates the medium to be transferred via the inlet valve (2). In the upward stroke, the diaphragm pushes the medium out of the pump head via the outlet valve (1). The diaphragm hermetically seals off the working chamber (3) from the pump drive (7).

Fig. 5: Low-pulsation operating principle

SIMDOS® diaphragm metering pumps are fitted with a patented drive system. The suction stroke is always driven at maximum speed, but the exhaust process is varied according to the selected speed, ensuring maximum possible uniformity of discharge during the entire stroke (see Fig. 4). This results in a low-pulsation, quasicontinuous transfer process. This is the key difference between SIMDOS® metering pumps and diaphragm metering pumps with linear magnet diaphragm drive or with conventional eccentric diaphragm drive.

The characteristic curve for the suction and exhaust strokes can also be adapted to the medium by setting the appropriate fluid type (see Section 7.11).

4.3 Valves

The SIMDOS is supplied with DuPont™Kalrez

valve disks as standard, but can also be supplied with valve disks made of CHEMRAZ

as an option.

WARNING

Danger of leaks and inaccurate metering caused by nonresistant valve materials

Using the wrong valve materials will result in inaccurate metering and possibly the complete failure of the valve system

➢ Check the resistance of any parts which come into con-

tact with the fluid (see chemical resistance list or consult your local KNF dealer, or contact lab@knf-flodos.ch)

➢ Avoid transferring media containing fluorine ➢ Regularly check that the pump is working properly and is

not leaking, especially when transferring aggressive and corrosive media

6.1 Safety

WARNING

Danger as a result of incorrect installation

Injuries or damage to equipment caused by escaping media

➢ Follow installation instructions ➢ After assembly, test the system with a harmless liquid ➢ Only use pump if it is in perfect working order

WARNING

Danger of serious injuries or property damage caused by escaping media in the event of rupturing of the pump diaphragm

Poisoning and caustic burns caused by escaping media as a result of rupturing of the pump diaphragm. If the pump diaphragm ruptures, the medium is channelled out of the pump through the discharge outlet.

➢ When transferring critical media, operate the pump in a

collecting tank

➢ Check discharge outlet for leaks

WARNING

Danger of serious injuries or property damage caused by escaping media in the event of overpressure on the suction side

Overpressure on the suction side will result in uncontrolled escaping of the fluid, even if the pump is not operating.

➢ Avoid overpressure on the suction side ➢ Fit a pressure control valve (see Section 6.3.3)

6.2 Installation

Before installation, store the pump at the installation location to bring it up to ambient temperature.

NOTE

For problem-free, safe operation the following instructions should be followed:

➢ Install in a dry place. ➢ Protect the installation location of the pump from water in

the form of rain, spray, splashes and drips.

➢ Do not operate the pump in an aggressive or inflammable

environment.

➢ Choose a safe location (a level, flat surface) for the pump. ➢ If the stability of the pump cannot be ensured, fasten the

pump in place using two screws.

➢ Make sure that the hose connections can be fitted without

strain on the hoses.

➢ Protect the pump against shocks, impacts and strong vi-

brations.

6.2.1 Connect mains plug

DANGER

6.2.2 Connect filter

CAUTION

Danger of excessive banking-up pressure (resistance) in the filter as a result of high particle concentration in the medium or a mesh size which is too small

This reduces the flow rate and causes errors in metering accuracy

➢ Use filters with a sufficiently large mesh size ➢ Filter fluid beforehand where appropriate ➢ Check filter penetration regularly, cleaning or replacing

the filter where necessary (see filter data sheet)

CAUTION

Danger of blocked filters as a result of excessive particle concentration in the medium

This reduces the flow rate and causes errors in metering accuracy

➢ Filter fluid beforehand where necessary ➢ Check filter penetration regularly, cleaning or replacing

the filter where necessary (see filter data sheet)

Many media contain solids or fibres that are not visible to the naked eye. In order to maintain reliable pump operation, a filter is to be used on the suction side.

Connect the filters supplied on the suction side

(for Order No. see Section 13.6). Set up the system in the fol-

lowing steps Rotate pump 90° anticlockwise Prime pump so that the air can escape from the filter. If there are no air bubbles in the system, the pump can be put

into operation.

7.11 Setting the fluid type

The "fluid type" setting is used to adjust the pump characteristic curve for different types of fluid.

Turn control knob until "Fluid Type" appears in the selection

window

Press control knob

 The current setting is shown by character on the right-

hand edge

The following settings are available for selection:

Fluid type: Standard

Symbol: S This is the optimum setting for all media with a viscosity similar to

that of water. A uniform flow characteristic curve is obtained with short suction times and appropriate linearisation.

Fluid type: Volatile

Symbol: D This is the appropriate setting for media with a low boiling point. As

these media are sensitive to any pressure drop and deceleration phenomena:

▪ The pump suction rate is reduced ▪ The transferring characteristic curve reduces fluid acceler-

ation and deceleration

Fluid type: Viscosity up to 100 cSt

Symbol: V The setting "Visc100cSt" is for media with a viscosity of up to

approx. 100 cSt. This setting alters the characteristics of the pump as follows:

▪ Suction rate is reduced ▪ Maximum flow rate is limited to 50 ml/min

Fluid type: Viscosity up to 500 cSt

Symbol: H This setting "Visc500 cSt" is for media with a viscosity of up to

approx. 500 cSt. This setting alters the characteristics of the pump as follows:

 The pump suction rate is significantly reduced  The maximum flow rate is limited to 20 ml/min

7.12 To calibrate the pump

The pump has already been precisely adjusted in the factory. However, the device will operate even more precisely if it is calibrated. Calibration eliminates any variances caused by supply lines, back-pressure and viscosity.

Calibration can be used to adjust the pump flow rate by ±20%.

Set up system Take an accurate measurement of the flow rate or metering

volume

Use the control knob to make the required menu selection [Cal.

100.0%]

Input the measured actual value with the control knob and

confirm (see Fig. 44)

Check the calibration with a repeat measurement.

NOTE

The calibration function uses the specified flow setting as the target value. This means the pump can always be calibrated for the current operating point.

NOTE

If the target flow rate still cannot be achieved after several calibration attempts, see "Troubleshooting" (Chapter 12).

8.5 Checking that pump is leak-tight

WARNING

Danger of bursting of the fluid system as a consequence of overpressure.

The pump builds up pressure. In a closed system the max. permitted operating pressure may be exceeded, thus causing damage to the pump and/or the system.

➢ In the case of parts that are in contact with the fluid, only

select those that are designed for the pump's operating pressure

➢ Do not transfer against shut-off devices or closed sys-

tems, or

➢ install pressure relief/safety valves and set them to 6 bar

(in the KNF product range)

In order to ensure correct assembly and hence reliability, it is essential to perform a leak test.

Fig. 57: Pressure test setup

Set up the system as shown in Fig. 57. Use distilled water as test medium. Set pressure control valve to working pressure. Make sure that the fitting is leak-tight

(see Section 6.2.3). Operate pump carefully for 5 minutes. Check pump for leaks.

If no traces of medium are visible on the head, the pump can be used in accordance with its specification (see Chapter 3).

Caution!

If it is found that liquid is escaping, under no circumstances should the pump continue to be used.

Check that connections are leak-tight. Check tightening torque of head screws. Check that elastomer parts are clean. Check leak-tightness again.

If these actions have no effect, contact your local KNF dealer and do not under any circumstances continue to use the pump.
