1.1. Use of the operating and installation

instructions

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

"PL" or "PML") 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

This symbol indicates a potential danger.

It also indicates the possible consequences of failure

to observe the warning. The signal word (i.e.

"Warning") indicates the level of danger.

 This specifies measures for avoiding the danger

and the consequences of failure to implement

these measures.

2. Use

2.1. Intended use

The pumps are intended for transferring and metering liquids.

Owner's responsibility

Only install and operate the pumps under the operating parameters

and conditions described in Chapter 4, Technical data.

Pumps must only be operated when fully assembled.

Before transferring or metering a medium, check that it can be

transferred without risk 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

pumped medium.

The temperature of the medium must lie within the permissible

temperature range (see Chapter 4).

The pumped medium should not contain particles as these can

prevent the pump from working correctly. If this cannot be

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

be used upstream of the pump.

2.2. Improper use

The pumps must not be operated in an explosive atmosphere.

For special modifications outside the standard technical

specifications please contact a KNF pump specialist.

Translation of Original Operating and Installation Instructions 4

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 pertinent 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 in perfect working order and in accordance

with their intended use. Always ensure adherence to the operating

and installation instructions and work in a safety-conscious

manner.

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

operating 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 pumping dangerous media, observe the safety regulations

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

legible condition.

All replacement parts should be properly stored and disposed of in

accordance with the applicable environmental protection

regulations. Ensure adherence to the pertinent national and

international regulations. This especially applies to parts

contaminated with toxic substances.

Dispose of all packaging in an environmentally appropriate

manner. The packaging materials are recyclable.

Ensure that the pump is disposed of in an environmentally

appropriate manner at the end of its useful life. Use

appropriate waste collection systems for the disposal of

end-of-life equipment. Used pumps contain valuable

recyclable materials.

KNF Flodos AG BA_NF1.60_EN_05_161566.docx

Translation of Original Operating and Installation Instructions 5

The pumps are in accordance with the requirements of the

guidelines 2011/65/EU (ROHS2)

Under Machinery Directive 2006/42/EC, pumps are partly

completed machinery, and as such should not be regarded as

ready for use. The partly completed machinery must not be put into

service until the final machinery into which it is to be installed has

been declared to be in conformity with the provisions of this

Directive. Always ensure implementation and enforcement of the

basic requirements of the Machinery Directive 2006/42/EC

according to Appendix I (General Principles).

The following harmonised standards are met:

NF 1.60 DCB-B / DCB-4B

 IEC/EN 61000-6-2

 IEC/EN 61000-6-3

NF 1.60 DC

 EN 55011

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

Customer Service team.

Only use KNF original parts for all maintenance work.

Fig. 2: Operating principle

Diaphragm liquid pumps are based on reciprocating displacement

pump technology. An elastic diaphragm (4) is moved up and down

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

stroke, the diaphragm sucks in the medium through the inlet valve

(2). During the up stroke, it forces medium out of the pump head

through the exhaust valve (1). The diaphragm hermetically seals

off the working chamber (3) from the pump drive (7).

This pump type represents this product in its simplest form and

delivers media at the specified flow rate.

6. Installation and connection

Only install the pumps under the operating parameters and

conditions described in Chapter 4, Technical data.

Observe the safety notes (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 to 5)

Translation of Original Operating and Installation Instructions 10

 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.

 The pump can be mounted in any orientation.

 Generally speaking, the pump can be mounted in any

orientation. For maximum precision and rapid venting, install

pump as shown in the illustration (Fig. 6).

 KNF recommends mechanically decoupling the pump from the

pipework system, e.g. by using flexible hoses or pipes. This

prevents any oscillations of the pump being transferred to the

system.

6.2. Electrical connection

For pumps with direct current motors:

 Pump should only be connected by an authorised specialist.

 Only connect the pump when the power supply is turned off.

 All electrical connection work must adhere to the pertinent

norms, directives, regulations and technical standards.

Connecting the pump

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

motor type plate. The current consumption can be found on the

type plate.

2. Connect the motor cables. For electrical data see Chapter 4.

Always check polarity of cables.

For DC motors:

red motor lead: +

black motor lead: -

In the case of brushless DC motors:

incorrect polarity may damage the electronics.
