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 “PU” or “MPU”), 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 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.
DANGER

6
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.
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.

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 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.
