1 General

1.1 Information about the instructions

The Installation Instructions describe the requirements for installing

the product correctly and safely into the complete machine.

These Installation Instructions are a part of the product. The safety-

relevant information should be taken over for the documentation of

the complete machine.

With customer-specific project pumps (pump types which begin

with “PL” or “PML”), there may be differences from the Installation

Instructions.

1.2 Warnings

Warnings in the Installation Instructions are marked by the hazard

symbol, the keywords, and the color. These features provide

information about the extent of the hazard.

DANGER

This indicates a dangerous situation that will directly cause death

or serious injury if not prevented.

WARNING

This indicates a dangerous situation that may cause death or

serious injury if not prevented.

CAUTION

This indicates a dangerous situation that may cause moderate or

slight injuries if not prevented.

NOTICE

This indicates a situation that may cause damage to property if

not prevented.

2 Safety

2.1 Intended use

The pump is intended solely for the following uses:

▪Transferring liquids and gases

▪For operation in accordance with the operating parameters

specified in the technical data of the supporting documents

2.2 Reasonably foreseeable misuse

The pump must not:

▪be operated in an explosive atmosphere

▪be used to transfer explosive media

▪be used to transfer media whose compatibility with the pump

head, valves, diaphragm, and seals has not been proven

2.3 Responsibility of the user

The user is responsible for ensuring that the safety precautions in

these Installation Instructions are complied with. Applicable safety,

accident prevention, and environmental protection regulations must

be complied with.

2.4 Product-specific risks

Remaining risks that were determined in a risk assessment are

described in this section. Safety precautions and warnings in this

section and in the other sections of the Installation Instructions

must be observed to prevent dangerous situations.

DANGER

Danger of injuries and damage to property due to dangerous

substances

Poisoning and chemical burns or unintended reactions caused by

leaking dangerous substances

➢Observe the safety data sheets of the transferred media.

➢Before transferring a medium, check whether it can be

transferred safely in the specific application case.

➢Ensure that the system is not subject to any risks of explo-

sion –not even under extreme operating conditions (tem-

perature, pressure) or in case of malfunctions.

➢Ensure the pump is used only by suitably trained, skilled

employees.

➢Clarify the chemical resistance of the head materials.

➢Check that the pump and the system do not leak at the op-

erating temperature of the transferred medium.

➢Check the pump for damage regularly.

➢Operate the pump only when you are sure it has no tech-

nical malfunctions.

➢Operate the pump in accordance with the technical data.

➢Work on the pump or fluid circulation system only after they

have been decontaminated and/or a decontamination decla-

ration is present.

KNF Flodos 178057_MA_FK1100_EN_00.docx

DANGER

Danger of injuries and damage to property due to leaks at the

interfaces to the pump head

Poisoning and chemical burns or unintended reactions caused by

leaking dangerous substances

➢Wear personal protective equipment.

➢Connect the pump correctly.

➢Operate the pump only when you are sure it has no tech-

nical malfunctions.

➢Operate the pump in accordance with the technical data.

DANGER

Danger of injuries and damage to property due to uncon-

trolled flow while the pump is not in operation

Poisoning and chemical burns or unintended reactions caused by

leaking dangerous substances

➢Construct the fluid system so that the operating pressure at

the pressure side of the pump is higher than at the suction

side.

➢Install a shut-off valve in the fluid circulation system.

The risk analysis indicates a risk of explosion from materials and

substances.

DANGER

Danger of injuries and damage to property due to an explo-

sion in the pump

The pump housing is made from aluminum. If the pump dia-

phragm is damaged, medium can accumulate in the housing and

form hydrogen (especially with acids and lyes). This could cause

an explosion in the pump housing.

➢Check and monitor the reactivity of the medium with alu-

minum.

➢No flammable materials in the direct vicinity of the pump or

piping

The pump housing is designed to withstand pressure surges

caused by explosions. The probability of a fault that would cause

an explosion is deemed to be low. When installed in the system,

the risks in the complete system must be assessed.

Safety Installation Instructions FK 1100

KNF Flodos 178057_MA_FK1100_EN_00.docx

DANGER

Danger of injuries and property damage caused by an explo-

sion in the connection lines and in the pump

Evaporation of flammable liquids

➢When flammable liquids are transferred, an explosive at-

mosphere can form in the pump and in the lines during fill-

ing and emptying.

➢With the hoses that are used, pay attention that no electro-

static charges can form (use conductive materials, ground-

ing and potential equalization).

➢The hoses and piping that are used must be able to with-

stand the expected pressure of explosion.

DANGER

Danger of injuries and property damage caused by the pump

exploding

If the pump has not been used or has been stored for some time,

residual medium may evaporate and, together with oxygen, form

an explosive atmosphere.

➢If the pump has not been used for some time or is stored,

empty the pump and rinse with neutral medium to prevent a

subsequent reaction.

WARNING

Danger of injuries and property damage caused by leaks to

the environment

Flammable materials

➢Keep flammable materials away from the direct vicinity of

the pump and piping.

2.5 Customer service and repairs

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.

3 Installation

WARNING

Danger from incorrect installation

Injuries or damage to property from leaking media

➢After installation, check the system for leaks with a safe

medium.

➢Observe the requirements for intended use.

➢Take precautions in the design of the end device so that

leaking liquids cannot come into contact with live compo-

nents.

➢Use only connections that are specified in the data sheet.

Do not use NPT threads or sealing tape, as cracks can

occur at the plastic connections.

The following requirements apply to all activities described in this

section:

3.1 Installation location

The installation location must:

▪protect the pump against immersion

▪keep aggressive and flammable liquids and vapors away

▪allow hoses to be connected without tensile or bending stress

▪take account of cooling the pump drive

▪ensure that any leaks can be handled

▪have appropriate precautions if flammable media are used

3.2 Mechanical mounting

▪Protect the product against impacts, knocks, and strong vibra-

tions.

▪Please refer to the product data sheet for dimensions, installa-

tion positions, and fluid connections.

CAUTION

Danger due to loss of stability

Injuries caused by the pump toppling over

➢Wear safety shoes with steel caps.

➢When the pump is installed in the machine, secure it with

screws or clamps.

➢When attaching accessories, make sure that the pump can-

not topple over.

3.3 Connecting the fluid system

Use suitable means to check the fluid connection for leaks.

For more information regarding dimensions, please refer to the

data sheet.

3.4 Electrical connection

For terminal assignment, output data, and control requirements,

please refer to the data sheet.

Observe the regulatory requirements for electrical installations:

▪Overload protection and separating protective devices

▪Contact protection and additional insulation

▪Ground connections

▪Protection against vibrations, tensile stress, and corrosion

WARNING

Danger of electric shock

If the pump is not installed correctly, there is a risk of electric

shock.

➢The electrical installation of the pump must be carried out

by a trained specialist who has relevant credentials.
