Master Instruments available to suit High Pressure Pump P12

The  following  manometer  types  can  be  directly  mounted  onto  the  High  Pressure 
Pump P12 without adapters. For further information about these products please 
refer to the specific datasheet.

General notes:

The  P12  pump  allows  the  easy  generation  of  pressure  up  to  700  bar.  The  pres-
sure  media  is  hydraulic  oil  (BP  HLP  22).  The  oil  chamber  volume  of  148  cm

3

  will 

pressurise large dead volumes. The pump has a fine pressure adjuster and release 
valve allowing precise pressure settings, making it the ideal test equipment for mano-
meters, pressure transmitters etc.

Using the High Pressure Pump P12:

  Connect the master instrument to connection (a). Tighten the instrument at the  
  hexagon, ensuring that the green Eolastic flat seal is flush mounted.

  Connect  test  unit  to  connection  (e)  with  the  high  pressure  quick-fit  connection  
  (supplied).

  Ensure that the pressure release valve (c) is not completely closed.

  Adjust the fine adjuster (b) to “mid-travel”.

  Close the release valve (c) fully clockwise.

  Operate lever arm (d) to generate pressure.

  Adjust  pressure  to  required  value  using  the  fine  adjuster  (b).  Turn  fine  adjuster  
  clockwise to increase pressure and anti-clockwise to decrease pressure until the  
  desired pressure is reached (displayed on master instrument).

   After measurements, open valve (c) slowly to release pressure.

  Remove test instrument

Note:

 Due to thermodynamical effects in the system, the pressure may fall slightly for a 

short time immediately after pressure generation. Use fine adjuster to stabilise pressure.

WARNING: To avoid possible destruction of the master- and test instru-
ments, do not exceed the max. operating pressure specified for these 
instruments!
