PV103R Pump Unit
Since the introduction of the PV103R in March 1994 there have been four build standards.With all four build standards there are two variants, the rack and flightline. Each standard hasimproved either the performance and reliability or extended the servicing period.The PV 103R rack-mounted variant provides pressure and vacuum supplies for use with other rack-mounted equipment (such as the ADTS 405) as part of an instrument and air data component servicing and testing facility. Alternatively the unit can be fitted in a trolley as part of a mobile air data test system.

3.Release the water drain trap from the spring clip, remove the drain pipe from the clear nylon bowl. Discard the water drain trap. Unscrew and remove the two screws securing the spring clip, discard the screws and spring clip.
4.Unscrew and remove the clips retaining the cooling coil. Discard the cooling coil and clips.
5.Front panel；Note：Take appropriate precautions to prevent swarf contamination of the unit from the following procedure. [Service tip - turn unit upside down when drilling.]
8.Connect the new pressure output pipe to the output port of the pump head. Connect the other end to the input connection of the water/cooler assembly.
9.Connect the new pipe to the output union of the water drain trap and the output connection of the rear panel. Connect the water drain pipe, make sure the other end locates in the grommet for correct venting of the water/cooler assembly.
10.Carry out an inspection of the unit look for loose connections and/or disturbance of the internal components.
11.Carry out a Standard Serviceability Test detailed in Chapter 5.

Build Standard 2：
Item：3-10a†；Description：..Valve, pressure release；Manufacturer's Part Number：AS405-18-1728M1；QTY：1
The second standard included improvements in materials and assembly methods that had been well proven during design/development of the military versions. A improved power supply included an upgraded motor control PCB. When this unit is used with an ADTS 405 the speed of the motor is controlled by the mode selection of the ADTS 405. During measurement mode the motor speed slows to reduce noise output and wear. An additional 15-way D-type connector was fitted to the rear panel to connect to the ADTS 405 mode selection.
Build standard 2 introduced a profiled spacer on the piston crown enabling the piston seals to be reversed for more effective vacuum generation. A new style of cylinder, with hard anodising and high polish, improved seal wear and reduced leakage. To keep stroke lengths correct a similar profile spacer is used on the pressure piston. Improvements to piston alignment with the piston seal changes has increased the servicing interval to 3000 hours. The output pressures can be sustained at 3.5 bar and 20 mbar absolute
Noise reduction has been achieved by increasing the filter area of the pressure air intake; air is drawn from inside the crankcase through an end-mounted porous plate. A robust three-axis anti vibration mounting reduces the effects of external vibration. Originally designed and developed for the ADTS 405F, this mounting fits into a surface mounting adaptor cradle.
