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

subsequent owners of the pump.

Customer-specific project pumps (pump models which begin with

"PL" or "PML") may differ from the Operating and Installation

Instructions.

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

agreed specifications.

2. Use

2.1. Intended use

The pumps are intended for transferring and metering liquids.

Owner's responsibility

Install and operate the pumps only under the operating parameters

and conditions described in Chapter 4. Technical data.

Only completely installed pumps may be taken into service.

Before transferring or metering a medium, check whether the

medium can be transferred danger-free in the specific application

case.

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

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

medium.

The temperature of the medium must lie within the permissible

temperature range (see Chapter 4).

The transferred medium should not contain particles as these can

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

teed, a filter < 100 m with sufficiently large filter area must be

used upstream of the pump.

 Filters may be ordered as accessories, see Spare Parts and

Accessories (Chapter 10).

2.2. Improper use

DANGER

The pumps must not be operated in an explosive

atmosphere.

Please contact your local KNF partner for special designs that

are not included in the technical specification (www.knf.com).

3. Safety

Observe the safety precautions in Chapters

6. Installation and connection and 7. Operation.

The pumps are built according to the generally recognised rules of

technology and in accordance with the pertinent occupational

safety and accident prevention regulations. Nevertheless, potential

dangers during use can result in injuries to the user or others, or in

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.

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.

Always ensure adherence to all information stickers on the pumps,

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

a legible condition.

All replacement parts should be properly stored and disposed of in

accordance with the applicable environmental protection regula-

tions. Ensure adherence to the pertinent national and international

regulations. This applies especially to parts contaminated with toxic

substances.

Dispose of all packaging in an environmentally-appropriate

manner. The packaging materials are recyclable.

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

contain valuable recyclable materials.

Translation of original Operating and Installation Instructions 5

The pumps comply with the fundamental requirements of Directive

2011/65/EU (RoHS2).

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 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.

The following harmonized standards are met:

NF 1.30 DCG

 EN 55014 - 1: 2001

All repairs to the pumps must be carried out by the responsible

KNF customer service team.

Use only genuine parts from KNF for servicing work.

Fig. 2: Pump assembly

The diaphragm liquid pumps are based on reciprocating displace-

ment pump technology. The elastic diaphragm (4) is moved up and

down by the eccentric (5) and the connecting rod (6). In the down-

ward 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).

6. Installation and connection

Install the pumps only under the operating parameters and condi-

tions described in Chapter 4. Technical data.

Observe all safety precautions (see Chapter 3).

6.1. Installation

 Before installation, store the pump at the installation location to

bring it up to ambient temperature.

 Mounting dimensions (see Fig. 3)

Fig. 3: Mounting dimensions NF 1.30 DCG

 Make sure that the installation location is dry and the pump is

protected against water in the form of rain, spray, splashes and

drips.

 Protect the pump against dust.

 Protect the pump against vibration and impact.

 Generally speaking, the pump can be installed in any position.

For maximum precision and rapid venting, install pump as

shown in the illustration (Fig. 4).

 KNF recommends mechanically decoupling the pump from the

piping system, e.g. by using flexible hoses or pipes. This pre-

vents any oscillations of the pump being transferred to the sys-

tem.

6.2. Electrical connection

 Only have the pump connected by an authorised specialist.

 Only have the pump connected when the power supply is

disconnected.

 When connecting the device to a power source, the relevant

norms, directives, regulations and technical standards must be

observed.

Connecting the pump

Make sure that the power supply data match the data on the

motor's type plate. The operating current can be found on the

type plate.

Connect positive and negative terminals. For electrical data

see Chapter 4

With DC motors, please pay attention to correct polarity:

red motor cable: +

black motor cable: -

6.3. Hydraulic connection

 Only connect components to the pump that are designed to

handle the hydraulic data of the pump (see

Chapter 4. Technical data)

 Only use hoses that are suitable for the maximum permissible

operating pressure of the pump (see Chapter 4).

 Only use hoses that are sufficiently chemically resistant to the

liquids being transferred.

6.3.1. Connecting the pump

Arrows on the pump head indicate the flow direction.

Remove the protective caps.

Connect the suction and pressure lines.

Keep the suction line as short as possible in order to keep the

priming process as brief as possible.

If the pump is used to build up pressure, make sure that all

transition joints between hose and pump are secure in order to

ensure that the hoses cannot come off.

Check that the hoses and transition joints are fitted correctly

and securely.

Check that the system is leak-tight.
