2. Product description .
2.1 General product information .


Application
Test pumps are used to generate pressures for checking, adjusting and calibrating mechanical and
electronic pressure measuring instruments by comparative measurements. These pressure tests may
be carried out in laboratories, workshops or on site at the measuring point.


Functioning
The comparison test pump is equipped with two connections for the test specimen and the reference
instrument which can be used in any order. If the instrument to be tested and a sufficiently accurate
reference measuring instrument are connected to the test pump, the same pressure is applied to the
two measuring instruments when the pump is operated. By comparing the two measured values at
random pressure values, the accuracy can be verified or the instrument under test can be adjusted.
First the pressure is set via an integrated initial pressure pump. For fine adjustment by approaching
the measuring points precisely an adjustable volume with precision spindle is available. Another
important feature of the pumps is the rotating spindle that only runs inside the body of the pump. This
eliminates the negative effect of a bending torque on a spindle turning outside the body and offers the
advantage, especially for use in the field, that the dimensions of these pumps do not change during
operation due to the spindle turning.
The term ”reference instrument” in this manual relates to each kind of pressure
measuring instrument like: spring manometer, electrical pressure measuring
instrument and pressure transmitters with electrical outlet. The comparison test pump
is only as precise as the used reference instrument. The reference instrument should
be recalibrated in regular intervals to guarantee the specifications of the manufacturer.

3. Commissioning and operation .
3.1 Preparation .
3.1.1 Setting up the device .
Set up the comparison test pump on a solid surface. If it is not resting on a solid foundation or is
subject to vibrations, measurements could be affected. This should be avoided.
The water level should be used to align the device. Using the rotating feed, position the device so
that it is horizontal.
The medium container may need to be filled, or refilled (volume 250 ml). For this purpose, the
locking screw with the filling symbol on top of the basement must be opened. Special oil must be
used for refilling (1 litre supplied, or available as accessory) or distilled water. The system must be
vented before initial filling, or after a complete medium change. For this purpose, please proceed
according to section 5.2.3.
Place the star handle with knobs onto the spindle pump. Ensure that the spring-loaded thrust pad
engages into the star handle bushing.
We recommend unscrewing the spindle pump completely when you start to record measurement
values, (turning anticlockwise) to allow enough volume for measurements. The outlet valve must be
opened during this process.

Operating InstructionsComparison Test Pump Version 1.0 10
3.1.2 Connecting the test specimen and the reference instrument .
Place the device to be checked and the reference instrument in the quick connector with the
knurled nut. They can be freely positioned. The order makes no difference. Hand-tightening will
suffice for safe sealing.
To calibrate instruments with back pressure entry there is an angle connection 90°available (see
accessories section 7).
Check the O-ring seals in the test connections for proper seat and for any wear.
Replace, if necessary.
Please see to it, that each instrument mounted to the test pump must be clean
inside.
The quick connectors come equipped with a G 1/2 threaded insert in the standard delivery
package.
When you are calibrating devices with different connection threads, the threaded
inserts can be changed as appropriate (see accessories "Adapter Set").
3.1.3 Venting the system .
After the clamping of the test specimen and the reference instrument, air may be trapped in the
system. The system may be vented before beginning with calibration using the following procedure:
The test specimen and the reference instrument must be clamped
The outlet valve must be closed.
Generate a pressure of approximately 50 bar using the initial pressure pump (Pay attention to the
measuring range of the instruments!)
Increase the pressure with the spindle pump until just below the final value of the measuring range
of the test specimen or of the reference instrument (the smaller pressure range is the decisive
factor).
Open the outlet valve, any trapped air will escape into the tank
This procedure may need to be repeated several times in order to remove all trapped air.
The device is now ready to use.

3.2 Operation .
The maximum permissible pressure for the LSP 1000-BM is 1,000 bar resp. forthe
LSP 1600-BM is 1,600 bar.Higher pressures may damage the pump. The
reference instrument, test specimen and any connecting tubes that are used
must not be subjected to pressures above the maximum permissible level.
3.2.1 Increasing the pressure .
The outlet valve must be closed.
Then run the initial pressure pump for several strokes. The pressure increases to a maximum of
about 50 bar (depending on the volume of the connected instruments).
After that, increase the pressure resp. make a fine adjustment by turning the built-in spindle pump
clockwise to approach the calibration points.
Now you can compare the indication of the test specimen with the reference instrument at each
calibration point.
If small amounts of air are compressed in the system together with medium, the test
pressure that has been generated first drops off slightly. After this it must be
readjusted.
A longer waiting time before stable operating conditions are reached should be
expected at higher pressures than at lower pressures.

Operating InstructionsComparison Test Pump Version 1.0 12
3.2.2 Reducing the pressure .
Turn the spindle pump anticlockwise to release pressure in the system.
If the pressure is close to the next test level, make the fine adjustment with the spindle wheel.
To release pressure more quickly or for venting, the fine adjustment valve can also be carefully
opened.
3.3 Disassembly .
After all pressure points have been recorded, open the outlet valve.
Now the test specimen and the reference instrument can be removed from the quick clamp.
Do not disconnect the test specimen or the reference instrument until the
pressure in the comparison test pump has been completely released.
In order to remove the star handle from the spindle pump, the spring-loaded thrust pad must be
pressed downward with the aid of a small screwdriver, or a ball-point pen. The star handle may
now be pulled off toward the front.

4. Troubleshooting measures .
If faults cannot be repaired, the system must be put out of operation
immediately and this information is to be given to the manufacturer.
Repairs must only be carried out by the manufacturer. Interventions and
changes on the appliance are not allowed.
In case of faults caused by defects of the hydraulic equipment the operators must inform their
superiors immediately and call in the qualified and authorised technical staff for maintenance.
Table: Fault description and measures .
Type of fault Measures
I. Unable to build up pressure / leak in the system Close outlet valve correctly
Attention: Do not tighten the fine
adjustment valve more than finger tight.
Otherwise the valve seat could be
damaged.
Check whether the seals have been
placed in the quick clamp for the test
specimen and the reference instrument
and whether they are properly positioned.
Check whether there is enough operating
fluid in the tank.
II. Unable to build up pressure, or range cannot
be reached
After the clamping of the test specimen
and the reference instrument, air may be
trapped in the system.
Please note: The system should be
vented before beginning with calibration.
For this purpose, proceed according to
section 3.1.3.
Afterwards, build the pressure back up.
III. Slow lowering of the pressure
Leak in the system, see fault I.
If small amounts of air are compressed in
the system together with medium, the test
pressure that has been generated first
drops off slightly. After this it must be
readjusted.
If the system is pressurised quickly, it
takes a certain time (< 1 minute) until it
can stabilise thermally. The pressure
should then be adjusted accordingly.
After the clamping of the test specimen
and the reference instrument, air may be
trapped in the system (hydraulic design
only), see point II.
Afterwards, build the pressure back up.

5. Maintenance .
5.1 Wear parts .
The O-rings in the test connections are subjected to wear. Both O-rings must be checked for proper
seat and any wear before any calibrating is performed. If necessary, the O-rings must be replaced in
regular intervals, or whenever necessary (see Accessories, section 7).
Important: Use original seals only. Seals having deviant measurements, or
materials, or material grades, may cause damage to the device and test
specimen, and pose a danger for the operator.
5.2 Changing the operating fluid .
The operating fluid should be changed whenever visible contamination is present.
5.2.1 Removing operating fluid .
Open the locking screw with the filling symbol on top of the basement
Siphon the medium out of the tank, for example, by using a suitable nozzle
Small amounts of medium residue additionally may be siphoned off the test connections opened
and with the outlet valve closed, by means of slowly turning in of the spindle pump
Minute amounts of medium residue may remain in the piping
In case of severe contamination of the operating fluid, the complete cleaning of the
piping and of all media-contacted individual components of the basement in a
dismantled state may be advisable. This procedure may be performed by the
manufacturer only.
For operating fluid hydraulic oil:
Waste oil must be disposed of according to legal requirements.

5.2.2 Filling in of operating fluid .
Turn in the spindle pump clockwise until it reaches the initial stop
Close the outlet valve
Open the locking screw with the filling symbol on top of the basement
Fill in special oil (1 litre supplied, or available as accessory) or distilled water via the tank opening,
until the fill level reaches the thread of the tank opening (approximately 250ml). The fill level must
always be observed.
Twist out the spindle pump counter-clockwise until it reaches the rear stop. The filling medium is
suctioned out of the tank into the system.
Close the tank opening with the locking screw
5.2.3 Venting of the system (after complete filling only) .
After initial filling, or after a complete medium change, air may be trapped in the system. The system
should be vented using the following procedure:
The test connections must be open
Close the outlet valve
Twist out the spindle pump counter-clockwise until it reaches the rear stop.
Carefully pump using the initial pressure pump, while continuously observing the filling medium in
the open test connections. At this point, trapped air escapes toward the exterior by means of the
formation of bubbles. The initial pressure pump must be actuated until air bubbles no longer
appear.
Any medium escaping in the open test connections should be siphoned off, for example, with a
nozzle.
