You have selected a high-quality KNF product; the following tips will help you operate it safely, and

reliably over a long period of time. Carefully study the Operating and Installation Instructions before

using the pumps and observe at all times the relevant instructions to avoid dangerous situations. The

manual was produced for the serial pumps stated above. With customer-specified projects (pump

types starting with “PJM“ or “PMM“) there could be differences in detail. For customer-specified pro-

jects please therefore take into account any agreed technical specifications, as well as these instruc-

tions.

1. About this document

1.1. Using the Operating and Installation Instruc-

tions

The Operating and Installation Instructions are part of the pump.

➔Pass on the Operating and Installation Instructions to the next

owner.

Customer-specific project pumps (pump models which begin with

"PJ", "PM", "PJM" or "PMM") may differ from the Operating and

Installation Instructions.

➔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.

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

protected against rain, splash, hose and drip water.

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, pump housing, diaphragms, 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.

The pumps are not suitable for transferring vapors and liquids.

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 Chapters 6. Installation and

connection, and 7. Operation.

The pumps are 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 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.

Make sure that only trained and instructed personnel or specially

trained 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"

chapter.

Observe the accident prevention and safety regulations when

performing any work on the pump and during operation.

When transferring dangerous media, observe the safety regula-

tions when handling these media.

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.

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.

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

assembled is in conformity with the provisions of the Machinery

Personnel

Directive 2006/42/EC. The following essential requirements of

Annex I of Directive 2006/42/EC (general principles) are applied

and observed:

−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.* /

(* only for pump type NMP 830 K_E)

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 (RoHS2).

The pumps conform to the EC Directive 2004/108/EC concerning

Electromagnetic Compatibility.

The following harmonized standards have been used:

Fig. 2: Pump head

The pumps transfer, compress and evacuate gases.

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.
