High Velocity Oil & Fuel Flushing

High Velocity Oil Flush

Welding slag, dirt, debris, and water often contaminate the inside of the tubing and piping of critical hydraulic oil, lube oil, and fuel oil systems.  OFS utilizes state-of-the-art high flow flushing equipment to achieve “turbulent flow” and a Reynolds Number of >4000 to effectively “flush” all contamination out of the piping, meeting or exceeding stringent cleanliness specifications established by leading OEMs (including GE, Solar, Caterpillar, etc.)

High Velocity Fuel Flush

It is very important to make sure that all piping and supply lines within critical fuel systems are free of moisture, particulate contamination, and debris.  For the exact same reasons that pre-commissioning and periodic maintenance flushing is necessary for hydraulic and lube oil system, it is also necessary for fuel systems in stand-by diesel generators and large diesel driven engines. 


OFS has specialized Fuel Flushing equipment to achieve “turbulent flow” through a wide range of fuel piping sizes, along with high efficiency filter elements designed to remove both particulate and moisture contamination to meet or exceed very stringent OEM cleanliness levels. 


Our Field Service Technicians all have extensive safety training and years of experience working with diesel fuel systems at Hospitals, Data Centers, and Fuel Farms within the Mining and Power Generation industries.

Thermal Transfer Fluid Flush

Sludge, solids, and other contaminants often accumulate within the piping of Thermal Transfer Systems, adversely affecting their thermal conductivity and overall performance.  Utilizing specialized cleaning agents, flush procedures, and state-of-the-art flushing equipment, OFS can quickly clean the entire system and restore it to “like new” condition and performance.

EHC Fluid Flush

OFS manufacturers and uses specialty flushing equipment designed for use with phosphate ester and other synthetic EHC fluids (including Fyrquel®).

Basics of High Velocity Oil Flushing

High Velocity Oil Flushing is an essential process to ensure optimal reliability of critical components within the lube oil systems of rotating equipment and hydraulic systems.  This White Paper gives a definition of terms (like “Turbulent Flow” and “Reynolds Number”) as they pertain to lube and hydraulic oil piping , and it explains why High Velocity Oil Flushing is such an important process for maintenance and reliability professionals at the plant level.  It also gives answers to some frequently asked questions, and discusses various “best practices” and procedures associated with proper configuration and execution of a High Velocity Oil Flush.

Fundamentals of High Velocity Oil Flushing

High Velocity Oil Flushing (HVOF) is performed to remove contaminants from the piping and tubing of critical hydraulic and lube oil systems.  It is an essential maintenance process that is designed to extend the life of rotating equipment, keeping turbines, compressors, engines, etc. operating at their optimal level, and improving their overall reliability.
