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”, “PMM”, “PU” or “MPU“) there could be differences in detail. For customer-

specified projects please therefore take into account any agreed technical specifications, as well as

these instructions.

1. About this document

1.1. Use of the Operating and Installation Instruc-

tions

The Operating and Installation Instructions are part of the pump.

➔Forward the Operating and Installation Instructions to any sub-

sequent owners of the pump

Customer-specific project pumps (pump models which begin with

"PJM", "PMM", “PU”, or “MPU”) may differ from the Operating and

Installation Instructions.

➔In the case of project pumps, take note of any additionally

agreed specifications.

1.2. Symbols and markings

Warning

WARNING

This symbol indicates a potential danger.

It also indicates the possible consequences of fail-

ure to observe the warning. The signal word (e.g.

"Warning") indicates the level of danger

➔Here you will see actions for avoiding the dan-

ger and potential consequences.

2. Use

2.1. Intended use

KNF pumps are to transfer, evacuate and compress gases and

gas-fluid-mixtures.

Owner's responsibility

Only install and operate the pumps under the operating parameters

and conditions described in Chapter 4, Technical data. Only com-

pletely installed pumps may be taken into service.

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

ferred danger-free in the specific application case.

Before using the pump, check the compatibility of the materials of

the pump head, pump housing, diaphragm, seals and valves with

the medium.

The temperature of the medium must lie within the permissible

temperature range (see Chapter 4).

The transferred media should not contain particles as these can

prevent the pump from working correctly. If this cannot be guaran-

teed, a filter < 50 m with sufficiently large filter area must be used

upstream of the pump.

See the type- plate or data sheet for full electrical and pneumatic

data.

2.2. Improper use

DANGER

The pumps must not be operated in an explo-

sive atmosphere.

The pumps are not suitable for transferring dusts and liquids.

Please contact your local KNF partner for special designs that

are not included in the technical specification.

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

pump.

3. Safety

Observe the safety precautions in Chapters

5. Installation and connection and 6. Operation.

The pumps are built according to the generally recognized rules of

technology and in accordance with the pertinent occupational

safety and accident prevention regulations. Nevertheless, dangers

may occur during their use which may 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 all personnel have read and understood the Oper-

ating and Installation Instructions, and in particular the "Safety"

chapter.

Always ensure adherence to all pertinent accident prevention and

safety regulations when working on and operating the pump.

When transferring dangerous media, observe the safety regula-

tions for handling such media.

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

Make sure the temperature of the medium is always sufficiently be-

low the ignition temperature of the medium, to avoid ignition or ex-

plosion. 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 be-

low the ignition temperature of the medium, even when it is com-

pressed to the maximum permissible operating pressure (Chapter

4) 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.

Always ensure adherence to all information stickers on the pumps,

such as flow direction arrows and type plates, and keep stickers in

legible condition.

All replacement parts should be properly stored and disposed of in

accordance with the applicable environmental protection regula-

tions. Observe the respective national and international regula-

tions. This especially applies to parts contaminated with toxic sub-

stances.

Dispose of all packaging in an environmentally-appropriate

manner. The packaging materials are recyclable.

Translation of original Operating and Installation Instructions, English 5

Dispose of end-of-life equipment in an environmentally

friendly manner. Use appropriate waste collection systems

for the disposal of end-of-life equipment. Used pumps con-

tain valuable recyclable materials.

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 com-

missioned until such time as it has been determined that the ma-

chine in which the partly completed machinery is to be assembled

conforms to the provisions of the Machinery Directive 2006/42/EC.

The 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. / 1.5.8. /

1.5.9. / 1.7.4. / 1.7.4.1. / 1.7.4.3.

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, hot

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

The pumps comply with the fundamental requirements of Directive

2011/65/EU; 2015/863/EU (RoHS).

All repairs to the pump(s) must be carried out by the relevant KNF

customer service team.

Exception service interval: see chapter 7.3.
