  • Page 4: Introduction

    1 Introduction 1.1 Description The PGHH hydraulic calibration pump is designed to manually generate up to 700 bar (70 MPa, 10 000 psi) for quick and accurate calibration of pressure gauges, transducers and other pressure measurement instruments. Read the instruction manual carefully prior to setting up and using the pressure pump.

  • Page 5: Standard Delivery

    The standard delivery includes: • Carrying case; • G 1/4 (1/4’’ BSP) plug to blank off the connection for an optional Beamex EXT External Pressure Measurement module; • G 1/4 (1/4” BSP) adapter (on the top) for connecting the optional Beamex EXT External Pressure Measurement module;...

  • Page 6: Operation

    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.
  • Page 7 The maximum total volume of the measurement system may not exceed 200 cc (12.2 cubic inches). The volume inside PGHH is less than 1 ml (on the pressurized side, not the reservoir, with maximum volume in the fine control). The volume of the unpressurized Pressure Measurement Hose is 3.5 ml...
  • Page 8 Ensure that all connections are made correctly and that the hose and the connectors are undamaged. Do not use faulty hoses or connectors. Use only the measuring hose provided by Beamex. Observe the effect of the operational conditions to the maximum pressure allowed in the hose. The specifications can be found in chapter 4.
  • Page 9 PGHH but not the instrument to be calibrated. Pump until drops of water/oil come out of the end of the hose. Then connect the instrument and raise pressure as described in the previous paragraph.
  • Page 10 In that case, adjust the pressure back to required value using the fine control. The principal tool for releasing pressure from the measurement system is PGHH’s fine control. Use of PGHH’s vent valve is also possible, but requires caution in order to avoid pressure shocks to the measurement system.

  • Page 11: Reservoir (Fluid Level)

    Do not overfill the glass reservoir. The glass reservoir does not withstand high pressure but it is not pressurized when PGHH is used correctly. Do not add fluid to the glass reservoir when increasing pressure. The reservoir may overflow and explode when the pressure is released and all the excess fluid returns from system to the reservoir.

    4.3 Storage Permissible conditions at the place of storage -10...50°C Storage temperature Humidity 35...85% relative humidity After each usage, the instrument has to be emptied and let dry out (drain screw at the bottom of the reservoir). Store the hydraulic calibration pump in its original packaging in a location that fulfills conditions listed below.
