Hydraulic Systems Limited
provide a unique oil flushing service, using conventional
or our patented equipment, developed to increase operating
efficiency and reduce timescales. This equipment, and
our team of experienced technicians, provide an effective
and highly economical service onshore, offshore and overseas,
for the rapid and effective clean up of lube, seal and
hydraulic oil systems.
Our equipment is compact, transportable, may be diesel
or electrically driven and configured to work in hazardous
areas.
Conventional Flushing Units
Hydraulic Systems Limited’s conventional flushing equipment has been
developed over many years to ensure the correct parameters are achieved during
flushing operations. Flowrates up to 10,000 L/min can be achieved using Hydraulic
Systems Limited equipment.
FlowMac
Our joint
Venture partnet Norson Services patented FlowMac technology
utilizing pulsing techniques allow pipe systems to
be effectively flushed in a shorter time with less
power demand and consumption.
FlowMac Nitro
Effective flushing of umbilicals or control lines up to 5km long is carried out by Norson's compact patented FlowMac Nitro Unit. The loading stage automatically charges the line with alternate slugs of oil and nitrogen. When pressure is released, turbulence occurs down the length of the line without the normal pressure drop problems encountered with conventional flushing.

Effective Flushing
In order for flushing to be effective:
- Turbulent flow must be achieved
- Reynolds No. must be > 4000
- High velocity required to remove contaminants
- High quality filtration must be used
Hydraulic Systems Limited’s
highly experienced technicians ensure that these criteria
are fulfilled to provide the fast,
cost-effective service.
Certification
On site certification of contamination levels to NAS 1638 and ISO 4406 are carried
out by technicians trained in manual particle counts using binocular microscopes
or automatic particle count equipment.
Conventional Flushing Units
Hydraulic Systems Limited use off-line filter units incorporating PALL high Beta
Ratio filters to provide efficient and rapid contamination removal.
