Pump Ranges
These operating instructions concern the following dry
running rotary vane pressure/vacuum pumps: Models
KLT 15 to KLT 40.
They have nominal capacities of 15, 25 and 40 m
3
/hr
operating on 50 cycles. The pressure and vacuum
limits (bar) are shown on the data plate (N). The tables
showing capacity against pressure can be found in
data sheet D 480.
Description
All models are complete with a vacuum and pressure
connection. All the air handled is filtered by a built-in
micro-fine inlet filter. Excess carbon dust from the
carbon blades is also filtered on the pressure side by
built-in filters.
Both the motor and pump have a common shaft.
The KLT (01
➝
06) and (08
➝
10) are encased in a
rugged black plastic sound enclosure. The cooling fan
for the KLT is located inside the sound enclosure. The
vacuum regulating valve (C) and the pressure regulat-
ing valve (D) can be adjusted to the required levels,
however, they are limited to a maximum point. (see

)
On the versions (03), (06), (09) and (10) the compressed air is cooled by an aftercooler.
The KLT (13) is located in a sheet metal cover. The motor fan provides the cooling. The KLT (13) has on the vacuum side, a vacuum safety
valve (C

) and on the pressure side, a pressure limitation valve (D

). (see picture

Optional extras (as required): Non return valve (ZRK), motor starter (ZMS) and pipe connection (ZSA).
Suitability
The units KLT are suitable for the use in the industrial field i.e. the protection equipments corresponds to EN DIN 294 table 4, for
people aged 14 and above.
The models KLT produce simultaneously pressure and vacuum between 0 and the max. limits, which are shown on the data plate (N). They may
be operated continuously.
The ambient and suction temperatures must be between 5 and 40° C. For temperatures outside this range please contact your
supplier.
These dry running pressure/vacuum pumps are suitable for use with air of a relative humidy of 30 to 90 %.
Dangerous mixtures (i.e. inflammable or explosive gases or vapours), extremely humid air, water vapour, aggressive gases or
traces of oil and grease must not be handled.
The standard versions may not be used in hazardous areas.
For all applications where an unplanned shut down of the pressure/vacuum pump could possibly cause harm to persons or
installations, a corresponding safety backup system must be installed.
Handling and Setting up (pictures
���
to
���
)
Pumps that have reached operating temperature may have a surface temperature at position (Q) of more than 70° C.
WARNING! Do Not Touch.
There must be a minimum space of 30 cm in front of the exhaust grid (G), suction grid (G
1
) and housing cover (b) for servicing. The cooling air
entries (E) and the cooling air exits (F) must have a minimum distance of 10 cm from any obstruction. The discharged cooling air must not be
re-circulated.
The KLT pressure/vacuum pumps can only be operated reliably if they are installed horizontally.
For installations that are higher than 1000 m above sea level there will be a loss in capacity. For further advice please contact your
supplier.
When the pumps are installed on a solid base, they do not need to be fixed down. If the pumps are installed on a base plate we would recommend
fitting anti-vibration mounts. This range of pressure vacuum pumps are almost vibration free in operation.
Installation (pictures
���
to
���
)
These units must not be operated without the standard pressure and vacuum regulating and limiting valves fitted so that the
maximum pressure or vacuum is not exceeded (see data plate).
For operating and installation follow any relevant national standards that are in operation.
1. Vacuum connection at (A) and pressure connection at (B).
Long and/or small bore pipework should be avoided as this tends to reduce the capacity of the pressure/vacuum pump.
2. The electrical data can be found on the data plate (N) or the motor data plate. The motors correspond to DIN/VDE 0530 and have IP 55
protection and insulation class F. The connection diagram can be found in the terminal box on the motor (unless a special plug connection is
fitted). Check the electrical data of the motor for compatibility with your available supply (voltage, frequency, permissible current etc.).
3. Connect the motor via a plug-connector (J) if fitted or via a motor starter. It is advisable to use thermal overload motor starters to protect the
motor and wiring. All cabling used on starters should be secured with good quality cable clamps.
We recommend that motor starters should be used that are fitted with a time delayed trip resulting from running beyond the amperage setting.
When the unit is started cold overamperage may occur for a short time.
The electrical installation may only be made by a qualified electrician under the observance of EN 60204. The main switch must
be provided by the operator.
