risk assessment. Safety precautions and warnings in this Chapter
and in other Chapters in the operating instructions must be observed in order to avoid dangerous situations.
DANGER
Danger of injuries and property damage caused by leaks in
connections and the pump head
Poisoning and caustic burns, or undesirable reactions caused by
escaping hazardous materials
➢ Maintain the tightening torque of connections (see Hydraulic connections)
➢ Check tightening torque of head screws regularly
➢ Only use pump if it is in perfect working order
➢ Operate pump in accordance with the technical data
DANGER
Danger of injuries and property damage caused by medium
escaping from the discharge outlet

escaping hazardous materials
➢ Place the pump in a suitable collecting vessel
➢ Never close the discharge outlet
➢ If medium escapes from the pump's discharge outlet, stop
using the pump and contact your KNF dealer
WARNING
Danger of serious injuries or property damage caused by
escaping media in the event of overpressure on the suction
side
Excessive pressure 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)
CAUTION
Danger of cavitation or particles in the fluid circuit
Errors in metering accuracy
➢ Use a prefilter, especially for media containing particulate
matter or fibres (see Chapter 6.2.2)

➢ Check the discharge outlet regularly for leaks
➢ Never close the discharge outlet (see Fig. 1)
➢ If medium escapes from the pump's discharge outlet, stop
using the pump and contact your KNF dealer
In the event that the pump diaphragm ruptures, the safety diaphragm prevents the transferred medium from penetrating into the
pump. If the pump diaphragm ruptures, the transferred medium is
channelled out of the pump through the discharge outlet (see Fig.
1).
2.7.2
Emergency Stop
Pulling out the mains plug acts as an Emergency Stop. If the pump
is installed permanently, an Emergency Stop and a maintenance
switch must be fitted.
2.7.3
Pressure control valve (optional)
In the event of overpressure on the suction side, the pump allows
the medium to flow through it freely. The pressure control valve
maintains a counterpressure of 0.5 bar and prevents the transferred medium from escaping. The pressure control valve is to be
used on the pressure side (see Section 6.3.3)

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)

Technical data
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 Section 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
Example:
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)

Operating principle
Pump assembly
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).

Patented drive system
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®5 valve disks as
standard, but can also be supplied with valve disks made of
CHEMRAZ®6 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 contact 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

Operation
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%.

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).

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 systems, 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.
