1. About this document

1.1. Using the Operating and Installation

Instructions

The Operating and Installation Instructions are part of the pump.

Always keep the Operating and Installation Instructions handy

in the work area.

Pass on the Operating and Installation Instructions to the next

owner.

Customer-specific project pumps (pump models which begin with

“PJ” or “PM”) may differ from the Operating and Installation Instruc-

tions.

For project pumps, also observe the agreed upon specifica-

tions.

1.2. Symbols and markings

2. Use

2.1. Proper use

The pumps are exclusively intended for transferring gases and

vapors.

Owner’s responsibility

Only install and operate the pumps under the operating parameters

and conditions described in Chapter 4. Technical Data.

Only complete pumps may be taken into service.

Make sure that the installation location is dry and the pump is pro-

tected against rain, splash, hose and drip water as well as other

pollutions.

The gas-tightness of the connections between the application

pipes and the pump (or the pump connection) must be checked

regularly; with leaky connections, there is a danger that hazardous

gases or vapors may escape from the pump system.

Before using a medium, check whether the medium can be trans-

ferred danger-free in the specific application case.

Before using a medium, check the compatibility of the materials of

the pump head, diaphragm and valves with the medium.

Only transfer gases which remain stable under the pressures and

temperatures occurring in the pump.

2.2. Improper use

The pumps may not be operated in an explosive atmosphere.

The pumps are not suitable for transferring;

dusts

liquids

aerosol

biological and microbiological substances

fuel

explosive and combustible materials

fibers

oxidizing agent

foodstuffs.

The pumps are not suitable for use with aggressive media. Other

pumps in the KNF product line are designed for use with aggres-

sive media. Please contact us for more information.

The pumps must not be used to create vacuum and overpressure

simultaneously.

An overpressure must not be applied to the suction side of the

pump.

3. Safety

Note the safety precautions in Chapter 6. Installation and con-

nection

and 8. Operation.

The pumps are built according to the generally recognized rules of

the 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 or other property.

Only use the pumps when they are in a good technical and proper

working order, in accordance with their intended use, observing the

safety advice within the Operating and Installation Instructions, at

all times.

Components connected to the pump must be designed to with-

stand the pneumatic performance of the pump.

Take care that safety regulations are observed when connecting

the pump to the electricity supply.

Make sure that only specially trained personnel or trained and in-

structed personnel work on the pumps. This especially applies to

assembly, connection and servicing work.

Make sure that the personnel has read and understood the Operat-

ing and Installation Instructions, and in particular the Safety chap-

ter.

Observe the accident prevention and safety regulations when per-

forming any work on the pump and during operation.

Ensure that the pump is separated from the mains and is de-

energized.

The pump heads heat up during operation – avoid contact with

them.

Make sure that there are no hazards due to flow with open gas

connections, noises or hot gases.

Ensure that an EMC-compatible installation of the pump is ensured

at all times and that this cannot lead to a hazardous situation.

When transferring dangerous media, observe the safety regula-

tions when handling these media.

If the diaphragm ruptures, the transferred medium will mix with the

air in the environment.

Take all necessary care to prevent this leading to a dangerous

situation.

Be aware that the pumps are not designed to be explosion-proof.

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 (Chapter 4).

If necessary, consider any external sources of energy, such as

radiation, that may add heat to the medium.

For pumps with AC motor:

When the operation of the pump is interrupted by the thermal

switch, the pump will re-start automatically after cooling down.

Take all care necessary to prevent this leading to a dangerous

situation.

In case of doubt, consult the KNF customer service.

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 inter-

national regulations. This especially applies to parts contaminated

with toxic substances.

For the purposes of the Machinery Directive 2006/42/EC, pumps

are “partly completed machinery”, and are therefore to be regarded

as not ready for use. Partly completed machinery may not be

commissioned until such time as it has been determined that the

machine in which the partly completed machinery is to be assem-

bled is in conformity with the provisions of the Machinery Directive

2006/42/EC. The following essential requirements of Annex I of

Directive 2006/42/EC (general principles) are applied and ob-

served:

−General Principles No. 1

−No. 1.1.2. / 1.1.3. / 1.3.1. / 1.3.3. / 1.3.4. / 1.4.1. / 1.5.1.* /

1.5.2.* / 1.5.8. / 1.5.9. / 1.7.4. / 1.7.4.1. / 1.7.4.3.

(*only for pumps with AC motor)

As these partly completed machinery are OEM-models the power

supplies and the equipment for disconnecting and switching-off the

partly completed machinery respectively have to be considered

when mounting as well as over-current and overload protective

gear.

In addition a protection against mechanical parts in motion and hot

parts, if existing, has to be provided when mounting.

The pumps conform to the Directive 2011/65/EU.

The following harmonized standards have been used:

The pump is maintenance-free. But KNF recommends, checking

the pump regularly with regard to conspicuous changes in noise

and vibrations.

Only have repairs to the pumps carried out by the KNF Customer

Service responsible.

Housing with voltage-caring parts may be opened by technical

personnel only.

Use only genuine parts from KNF for servicing work.
