1. Safety instructions
Read these operating instructions carefully prior to operating the hydraulic
calibration test pump PGS 700 / PGS 1000. The pressure inside the pump can be
extremly high. Ensure that all pressure connections have been established
correctly.
2. Product description
The PGS 700 and PGS 1000 calibration test pumps are used to generate pressure 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..
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 calibration test pumps PGS 700 and PGS 1000 are
easy 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 optional HTH 1000 flexible hose.
(1) = Test hose connection (hose optional)
(2) = Pressure relief valve
(3) = Filling plug of liquid reservoir
(4) = Fine adjustment valve
(5) = Pressure port for reference
(6) = Liquid reservoir
(7) = Switching knob priming / high pressure
(8) = Handles
(9) = (Blind plug - do not open!)
3. Mounting instructions
• The reference instrument is fitted to the upper side of the calibration test pump PGS
700 or PGS 1000. 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 PGS 700 and PGS 1000. Do not connect to
external pressure sources.

4. Operation (pressure)
• Make sure, the PGS 700 or PGS 1000 is in priming position. If necessary, press the
switching knob (7).
Switching knob (7)
handles in position..... - priming - - high pressure generation -
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.
As an accessory, a stainless steel set of adapters is available to cover several 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 ( water based!) or clean water, free of
calciumcarbonate / scale ( distilled water!). (Optional: PGS 1000 Execution “S”
to be used with brake fluid or Skydrol).
• Fill the liquid reservoir (6) up to the lower edge of the aluminum label (type label,
placed around the liquid reservoir).
not
no
• 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

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 (Order-No. PGS700-SK) consisting of spare sealing gaskets and o-rings, is
available as an accessory.

?If the pressure cannot be generated correctly of 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 calibration 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 calibration test pump.
?Never connect an external pressure supply system to the PGS 700 or PGS 1000
calibration test pump.
