LABOPORT Pumps and Systems Use

2. Use

2.1. Proper Use

The pump/system is exclusively intended for transferring gases and vapors.

Owner's responsibility

Operating parameters and

conditions

Requirements for

transferred medium

High performance condenser

Accessories

Only install and operate the pump/system under the operating parameters and conditions described in chapter 5, Technical data.

Make sure that the installation location is dry and the pump/system is protected against rain, splash, hose and drip water.

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

Before using a medium, check whether the medium can be transferred danger-free in the specific application case.

Only transfer gases which remain stable under the pressures and temperatures occurring in the pump.

The high performance condenser must be installed on the outlet side of the pump; if it is installed on the inlet side there is a danger of implosion.

Observe the correct usage of the gas- and cooling liquidconnections on the high performance condenser. Inlet and outlet connections for the gas are not interchangeable.

Laboratory equipment or additional components connected to a pump/system have to be suitable for use with the pneumatic capabilities of the pump (see chapter 5.1, page 10).

2.2. Improper Use

The pump/system may not be operated in an explosive atmosphere.

The pump/system is not suitable for transferring dusts.

The pump/system is not suitable for transferring liquids.

For LABOPORT systems with vacuum controller: The vacuum system must not be used if the entry of air or gas into the vacuum system during venting (pump vent valve) could result in the creation of reactive, explosive or otherwise hazardous mixtures (e.g. with the medium).

The pump/the system must not be used to create vacuum and overpressure simultaneously.

An overpressure must not be applied to the suction side of the pump/ the system.

Safety LABOPORT Pumps and Systems

3. Safety

Note the safety precautions in chapters 7. Installation, mounting and connection, and 8. Operation.

The pump/system is built according to the generally recognized rules of technology and in accordance with the occupational safety and accident prevention regulations. Nevertheless, dangers can result during their use which lead to injuries to the user or others, or to damage to the pump/system or other property.

Only use the pump/system when it is in a good technical and proper working order, in accordance with its intended use, observing the safety advice within the operating instructions, at all times.

Personnel

Working in a safety-

conscious manner

Fig. 1: Notice sticker

Handling dangerous media

Handling flammable media

Make sure that only trained and instructed personnel or specially trained personnel work on the pump/system. This especially applies to assembly, connection and servicing work.

Make sure that the personnel has read and understood the operating instructions, and in particular the "Safety" chapter.

Observe the accident prevention and safety regulations when performing any work on the pump/system and during operation.

Do not expose any part of your body to the vacuum.

Open housing parts with notice sticker (see fig. 1) only after separating mains plug from power source.

When transferring dangerous media, observe the safety regulations when handling these media.

Be aware that the pump/system is not designed to be explosionproof.

Make sure the temperature of the medium is always sufficiently below the ignition temperature of the medium, to avoid ignition or explosion. This also applies for unusual operational situations.

Note that the temperature of the medium increases when the pump compresses the medium.

Hence, make sure the temperature of the medium is sufficiently below the ignition temperature of the medium, even when it is compressed to the maximum permissible operating pressure of the pump. The maximum permissible operating pressure of the pump is stated in the technical specifications (see chapter 5.1, page 10).

If necessary, consider any external sources of energy, such as radiation, that may add heat to the medium.

In case of doubt, consult the KNF customer service.

Environmental protection

6 Translation of original Operating Instructions, english, KNF 121211-121345 01/10

Store all replacement parts in a protected manner and dispose of them properly in accordance with the applicable environmental protection regulations. Observe the respective national and international regulations. This especially applies to parts contaminated with toxic substances.

Function Diaphragm pump

Fig. 5: Pump head

Diaphragm pumps transfer, compress (depending on pump version) and evacuate gases and vapors.

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 gas to be transferred via the inlet valve (2). In the upward stroke, the diaphragm presses the medium out of the pump head via the outlet valve (1). The transfer chamber (3) is hermetically separated from the pump drive (7) by the diaphragm.

12231

Function

In laboratory systems without a vacuum controller the pump runs continuously and works against its vacuum. If there is a vacuum controller, it will switch the pump off once the selected target vacuum has been reached.

With two vacuum controllers it becomes possible to simultaneously run two different and independent processes with just one pump.

Once one vacuum controller’s set point has been reached, that vacuum controller will close the valve it is controlling. If two vacuum controllers are used, the pump will continue to work until the second controller’s set point has been reached. Then the second vacuum controller will close the valve it is controlling. The pump switches off and the pump vent valve is opened.

If one of the two vacuum values falls below the hysteresis range, the pump will switch back on.

Refer to the vacuum controller’s operating instructions for more information.

reduction and post distillation time can be altered in automatic mode, however not until the first boiling point has been achieved.

 The last entered values are

retained once the system is switched off.

 The value inputs can be viewed at

any time (in „mbar“ display flashing):

 Pressure differential:

Press the SET key twice;

 Pressure reduction:

Press the SET key three times;

 Post distillation time:

Press the SET key four times.

5.3 Running

 Press AUTO key.

 In the "mode" display "A1" appears

and the start-up level of 600 mbar.

 The SET key, the UP key and the

DOWN key can not operated.

 The vacuum controller searches for

the first boiling point step by step and with short gaps.

 Once the first boling point has

been achieved, the code "bP" for "boiling point" appears on the "mode" display.

 The value found (first boiling point)

becomes the pressure set-point.

 If no values for pressure reduction

d and post distillation time t have been stored, the controller regulates the new pressure setpoint until this process is halted by pressing the STOP button.

 If values for pressure reduction d

and post distillation time t are stored, the pressure will be reduced after the distillation point has been found.

 "Mode“ display shows status

"bP". Alternating with "bP" the remaining post distillation time appears in minutes.

 When the pressure has been re-

duced:

- the controller switches off;

-display „mode“ shows „End“;

-a signal sounds ( 3 x 10 seconds)

-the vacuum valve closes, the system remains under vacuum.

 Press the STOP key to finish.  If the system is to be restarted eg.

in order to distill the solvent using the next lowest boiling pressure, after having pressed the STOP key (and possibly changing the d and t values), the AUTO key has to be

 Once the first boiling point has

been found an exchange on the manual mode is possible by pressing the MAN key. The „bP“ value will be retained as temporary pressure setpoint.

 The automatic mode can be stop-

ped by pressing the STOP key at any time.

6. Changing of Pressure unit

The physical unit indicating the pressure can be chosen between mbar and torr.

 When the controller is switched

off, press the AUTO-Key  and switch on the contoller with the On/Off-Switch  at the same time.

 With the DOWN-Key  and the

UP-Key  you can choose between the units hPA (mbar) and torr.

 The LEDs for mbar  and torr 

show the selected pressure unit.

 Press STOP-Key .

 The new pressure unit will be

stored after 5 seconds.

 The contoller changes to the

operating mode.

7. Calibration

 Whilst pressing the SET key,

switch on the Vacuum Controller.

 The "mode" display shows "CAL“.  If the "mode" display does not

show "CAL“, press SET key.  The "mode" display shows

"CAL“.

 Press the UP key.

 The "setp“ display shows "H1“ .

 Insert the actual atmospheric pres-

sure, using the UP or DOWN key.

 Press SET key to override.

8. Trouble Shooting

 Sufficient vacuum is not reached

Possible reasons:

 Tube connections are not tight, or

an external valve is open.
