1.2 Safety instructions .
Read these operating instructions carefully prior to operating the hydraulic
hand test pump CPP 700-H / CPP 1000-H. The pressure inside the pump can be
extremly high. Ensure that all pressure connections have been established
correctly.
2. Product description .
The CPP 700-H and CPP 1000-H hand test pumps are used to generate pressure for checking,
adjusting and calibrating mechanical and electronic pressure measuring instruments by co mparative
measurements. These pressure tests may be carried out in laboratories, workshops or on site at the
measuring point.
If the instrument to be tested and a sufficiently accurate reference measuring instrument are
connected up to the test pump, the same pressure is applied to the two measuring instruments when
the pump is operated. By comparing the two measure valves at random pressure values, the accuracy
can be verified or the instrument under test can be adjusted.
Despite their compact dimensions, the hand test pumps CPP 700-H and CPP 1000-H a re e asy to
operate and allow for exact generation of the required test pressures. The pumps are fitted with a fine
adjustment valve for the precise adjustment of pressures. The reference instrument is screwed directly
on the top of the pump and the unit under test is connected by means of the pressure hose
incorporating a 1/4" BSP female thread, contained in the scope of delivery.

3. Mounting instructions .
The reference instrument is fitted to the upper side of the hand test pump CPP 700-H or
CPP 1000-H. The reference instrument is sealed by the integral O-ring sealing gasket. The
maximum torque is 15 Nm.
The unit under test is mounted to the end of the flexible test hose. Tighten to the connector to
prevent any leaks to a maximum torque of 15 Nm.
Never apply external pressure to the CPP 700-H and CPP 1000-H. Do not
connect to external pressure sources.
As an accessory, several stainless steel sets of ad apters are available to cover different thread
dimensions of your test specimen.
Tighten the optional adapters to a maximum torque of 15 Nm.
Tip: It is possible to connect the test specimen directly to the pump. After dismounting
of the hose connector, there is a 1/4" BSP female thread at the side of the pump body.
Open the filling plug (3) of the liquid reservoir (6) and fill with a suitable fluid:
mineral oil based hydraulic fluid or clean water, free of calcium-carbonate / scale.
(Not suitable for hydraulic oils based on water and destilled water.)
Fill the liquid reservoir (6) not completely full

4. Operation (pressure) .
Make sure, the CPP 700-H or CPP 1000-H is in priming position. If necessary, press the switching
knob (7).
Switching knob (7)
handles in position - priming - - high pressure generation
Make sure that the release valve (2) is open.
Turn the adjustment valve (4) counter-clockwise fully out (smooth “stop” can be felt)
Turn the release valve (2) clockwise until the vent is closed.
Operate the handles (8) for priming, until the handles (8) are just before they cannot be pressed
fully together anymore, due to the generated priming pressure. Depending on the volume of the
calibration circuit, this can be at app. 200 to 400 bar / 3000 to 6000 psi.
Keep the handles (8) pressed together and operate the switch knob (7). The handles (8) are now in
“high pressure” position.
NOTE: if the generated priming pressure is too high and - as a result - it is no longer
possible to press the handles (8) fully together, please open the release valve (2) (turn
counter-clockwise) and try it again.
Operate the handles (8) until the required pressure is nearly achieved, but max. to app. 600 bar /
9000 psi. Higher pressure is made by turning the adjustment valve (4) clockwise.
NOTE: After increasing the pressure, the reading may slightly drop again for about 30
seconds, which is caused by thermodynamic effects, the tube connection and the
sealing gaskets. If the pressure drop does not come to a standstill, check the
measuring circuit for tightness.

A pressure reduction is achieved by turning the fine adjustment valve (4) anticlockwise first and
then by carefully opening the relief valve (2).
NOTE: For releasing the pressure please turn the release valve (2) only max. 1
revolution counter-clockwise. Afterwards close it again by turning clockwise.
Remove the reference instrument or the test specimen only when the relief
valve (2) is open and no pressure is in the test pump any more.
5. Maintenance instructions .
Prior to connecting the reference instrument and the test specimen, the sealing gasket in the two
connectors should be checked for correct position and wear, and should be replaced, if and when
necessary.
A service kit consisting of spare sealing gaskets and o-rings, is available as an accessory.
It is only allowed to clean the liquid reservoir with water or mild detergents. By
the use of alcohol, ethyl alcohol (spirit), acetone or benzol crack formations can
arise in the material of the reservoir and the reservoir can be damaged.
6. Cause of fault .
If the pressure cannot be generated correctly or if the set pressure does not stay stable, this is
likely to be caused by the incorrectly positioned or selected sealing gaskets. Please also check
wether any adapters used on the test specimen have been tightened sufficiently to eliminate leaks.
Before assuming there is a leak in the hand test pump:
First of all, check if the relief valve (2) is closed.
If the test pump has not been used for a longer period of time, the first lift may be somewhat
sluggish. This effect will disappear again during further operation.
By no means apply any force to the operating elements of the hand test pump.
Never connect an external pressure supply system to the
CPP 700-H or CPP 1000-H hand test pump.
