2 Operation
Wear protective glasses.
Do not use PGHH in any other way than as described in this manual.
Use only the connectors provided with the pump. Impurities from wrong materials may plug the pump.
Do not exceed the maximum operating pressure of the pump and the hose. Also observe the pressure
limit set by environmental conditions and the used pressure medium.
The pump is tested using water. Small amounts of water may still be inside the pump when you
receive it. Flush the pump with the pressure media to be used before connecting any instruments to it.
If you use water as the pressure medium, make sure that you store PGHH in temperatures above the
freezing point.
2.1 Operating instructions
1. Connect the optional external pressure module (EXT) to the pump (see 3 in figure 1)
using the appropriate seals (it is strongly recommended that the bonded seal
under the plug is used under 600 bar and copper seal above 600 bars).
Ensure that the measurement range of the connected module is appropriate.
2. Remove filling plug and fill reservoir (for 2/3
to max. 3/4) with the appropriate fluid
(don’t exceed the maximum level) and replace plug.
