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
“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.

Diaphragm Pumps UNMP05, UNMP09, UNMP015_I
1.
Description, Operating Conditions
KNF pumps in the NMP range transfer, evacuate and compress
100% oil-free. In operation they are maintenance-free
ƒ
See the type- plate or data sheet for full electrical data.
1.1. Operating Conditions
Handling air, gases, and vapours at temperatures between
+ 5 °C…+ 40 °C.
For maximum permissible operating pressure, ultimate vacuum,
and flow capacity see data sheet.
Ambient temperature during operation: between + 5 °C…+ 40 °C
The pumps must not be used in areas where there is a danger of
explosion.
Before pumping a medium, the compatibility of materials of pump
head, diaphragm and valves with the medium must be checked (for
pump materials: see data sheet).
KNF pumps in the NMP range must not be used for liquids. You
will find suitable liquid pumps in our Product Program.
If your potential application lies outside the above limits discuss it
with our technical adviser (see last page for contact telephone
number).
2.
Safety
Note the safety precautions in chapters 3. Installation and
connection, and 4. Operation.
The pumps are built according to the generally recognized rules of
technology and in accordance with the 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 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.
Personnel
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
Operating and Installation Instructions, and in particular the
"Safety" chapter.
Working in a safetyconscious manner
Handling dangerous media
Handling combustible media
2
Observe the accident prevention and safety regulations when
performing any work on the pump and during operation.
When transferring dangerous media, observe the safety
regulations when handling these media.
Be aware that the pumps are not designed to be explosion-proof.
Diaphragm Pumps UNMP05, UNMP09, UNMP015_I
Description, Operating Conditions
Make sure the temperature of the medium is always sufficiently
below the ignition temperature of the medium, to avoid ignition or
explosion. 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
below the ignition temperature of the medium, even when it is
compressed to the maximum permissible operating pressure 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.
Environmental protection
EC Directives / Standards
Store all replacement parts in a protected manner and dispose of
them properly in accordance with the applicable environmental
protection regulations. Observe the respective national and
international regulations. This especially applies to parts
contaminated with toxic substances.
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
assembled is in conformity with 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 pumps conform to the EC Directive 2004/108/EC concerning
Electromagnetic Compatibility.
The following harmonized standards have been used:
UNMP05M
UNMP09M
DIN EN 61000-6-3
UNMP05L
UNMP09L
UNMP015L
DIN EN 55022 (Klasse B)

Installation
Pumps in the NMP range are OEM models intended for
installation in equipment. When installing them make certain
that accident prevention regulations, and safety instructions,
including those for subsequent operation are observed.
The dimensions of the mountings are given in Data Sheet.
Fit the pump at the highest point in the system, so that condensate
cannot collect in the head of the pump - that prolongs working life.
Compare the supply data with the motor data.
With dc motors the wires must be connected to the correct poles.
For brushless DC motors (type designation ending with B):
ƒ
Caution; incorrect lead connection will damage motor
electronics.
ƒ
Correct connection:
+ red cable
- black cable
In the electrical installation, arrangements (compyling with EN
60335-1) must be made for disconnecting the pump motor from the
electrical supply.

Description, Operating ConditionsOperation
Operation
Specific safety instructions for the media being handled must
be observed.
Before pumping a medium, the compatibility of materials of pump
head, diaphragm and valves with the medium must be checked (for
pump materials: see data sheet)
The pump must not start against pressure or vacuum. When it is
switched on the pressure in the suction and pressure lines must be
atmospheric.
The maximum permissible operating pressure (see data sheet)
must not be exceeded.
Exception: If the data sheet includes values for intermittent
operation, they may employed briefly.
To prevent the maximum permissible operating pressure being
exceeded, restriction or control of the air or gas flow should only be
carried out in the suction line.
If restriction or control of the air or gas flow is made on the
pressure side ensure that the maximum permissible operating
pressure is not exceeded.
When the pump is at a standstill the inlet and exhaust must be at
normal atmospheric pressure.

Trouble Shooting

5.
Trouble Shooting
Flow, pressure or vacuum are too low, or: Pump produces no
flow:
ƒ
Connections or lines are blocked.
ƒ
There is a leak at a connector, in a line, or in the pump
head.
ƒ
An external valve is closed, or a filter blocked.
ƒ
Liquid (condensate) has collected in the pump head.
`
Let the pump run for a few minutes pumping air (if
necessary for safety reasons: pumping an inert
gas.)
`
Install the pump at the highest point in the system.
ƒ
The cross-section of pneumatic lines, or connected components is too small, or they are restricted.
ƒ
There is pressure on the pressure side, and at the same
time vacuum, or a pressure above atmospheric, on the
suction side:
