Flushing of accumulators is carried out at QHP using dedicated flushing rigs. Using dedicated flushing equipment eliminates cross contamination from differing fluid types such as water/ethylene glycols, mineral based fluids and synthetic fluids.

Particle counting is carried out using a laser based fluid analyser. The system analyses bottle samples taken from accumulators during flushing to verify that the fluid conforms to customer requirements or a specific specification. Fluid cleanliness can be verified to NAS 1638 or AS SAE 4059.

QHP have several flushing rigs, as standard we can flush with the following fluids:

  • Castrol Transaqua HT
  • Castrol Transaqua HT2
  • Mineral Oil
  • Castrol Brayco Micronic SV/3
  • Macdermid Oceanic HW443

We also have a dedicated rig for small accumulators and diaphragm accumulators.

Other fluids are available on request, please contact QHP for more details.
