We offer comprehensive oil flushing services for industrial and marine applications
Our methods include high velocity hot oil flushing and may include pipe agitation, rapid oil temperature changes and chemical cleaning. Our flushing systems include BETA 1000 rated absolute filtration and vacuum dehydration.
All of our systems are equipped with laser particle counters and moisture content meters to give real time ISO or NAS Cleanliness Codes. At the end of flushing job, a comprehensive report is submitted documenting the oil cleanliness and dryness through multiple methods.
Our team adheres to strict safety procedures and spill awareness and response and strives to get the work done safely and efficiently during equipment outages, startups, and during or after system repairs or maintenance.
Typical oil flushing jobs include: steam, gas and hydro electric turbine lube oil systems, compressors, paper machines, hydraulic systems, EHC governor systems, seal oil systems or any other industrial or marine lube or hydraulic system where flushing and purification is needed.
Our methods have been proven for clients including the U.S. Army Corps of Engineers, GE, Kapstone Paper, The US Navy and many more.
Completed Oil Flushing & Purification Job Examples:
U.S. Navy Hydraulic Oil Purification for the U.S.S. Ohio Trident Nuclear Submarine at Puget Sound Naval Shipyard & IMF
High purity Northwest was selected to perform critical oil purification as part of a complete hydraulic system flush for this very important military asset. The system had been contaminated with water and particulate and all the fluid on board the vessel was in need of extensive dehydration and fine filtration. Our specialized systems and processing tanks were used to quickly restore the fluid to much cleaner and drier than navy specifications. Time of processing was critical in this application as there were large amounts of fluid needing to be processed in a short period of time. Our team was on station for months and tens of thousands of gallons of fluid were processed.

High Purity Northwest, Inc. Post Award Conference N4523A18P0819 – Hydraulic Oil Cleaning
Army Corps of Engineers Ballard Locks Large Lock Hydraulic Systems
High Purity Northwest Inc was selected by the US Army Corps of Engineers, Seattle District to perform a service of the main hydraulic systems for the large locks at the Lake Washington Ship Canal Ballard Locks. The job had a time window as the Ballard Locks are a critical passageway for commercial vessel traffic in the area. The large locks hydraulic systems could only be taken off line during the annual maintenance shutdown and could only be down for two weeks. The job is also in an extremely environmentally sensitive marine area, so equipment containment and zero oil spillage were of the utmost importance.
The job summary included complete drainage of the hydraulic systems, cleaning of the hydraulic reservoirs, replacement of all of the hydraulic hoses, inspection of all of the hydraulic components, complete fill and purge of the system with new oil and then flushing of each circuit to an ISO 4406 Cleanliness code of 17/15/12 and also moisture removal to less than 100 PPM residual water content.
The job had many logistical and environmental protection challenges, but the High Purity Northwest team completed the job ahead of schedule and we exceeded all of the performance specifications set forth by the USACE.
The equipment used included the latest technologies in vacuum dehydration, high velocity flushing, filtration and oil heating & cooling.
Nippon Paper New Power Plant GE Turbine Pre-Commissioning Hot Oil Flush
Our Team was chosen to perform a complete lube oil system flush for a new steam turbine at a major paper manufacturing plant. General Electric required the entire lube oil system to be flushed to specific and stringent ISO Cleanliness Codes and for this to be formally documented prior to commissioning of the new plant. Our flushing and filtration systems and specially designed flushing tank shown in the photos of the work site below are key components in reaching the target cleanliness levels fast.
