Over View on Turbine Lube Oil System Flushing – Trends and practices

System Contamination :

Type of contaminants in the lube / Hydraulic System pipe wok / components usually found during initial erection & commissioning stage:
a). Welding Splatters
b). Metal Grinding chips & Silt
c). Fluid Sealing Material
d). Rust and scaling material
e). Silica and black metal
f). Cotton waste / small left out tools like nuts & bolts etc.

Effects of Contamination :
a). Catastrophic failure
b). Shorter Bearings / components life
c). Forced outages / down time
d). System reliability issue.

General Flushing Requirements:
Most of the lube oil systems are designed with “laminar” flow conditions. This means constant operation without cavitation or vibrations. The problem with laminar flow is that with time impurities will deposit on the inside of your system and will not be carried out and caught by the inline system filters.

In order to obtain an efficient cleaning of the system, it is therefore necessary to use flushing with turbulent flow, which will dislodge and remove the impurities on the inside of the system Oil flushing is more than just starting up the internal system pump and employing the external flusher to circulating the oil through the system with high velocity and turbulent flow to ensure the effective cleaning .

The contamination collected in the process of the flushing needs to be trapped with high efficiency filters

General Flushing Conditions:

Flushing must take place after piping installation, but prior to system operation. The success of oil flush is dependent on:
Success of efforts to keep contaminants out, and the proper conduct of the flush.
A successful flush means that system piping components and piping meet acceptance criteria in a minimum of time with a minimum of effort.

BTG & CHP Lube/Hydraulic Oil System Filtration

Filtration plays a vital role in improving process efficiency and plant safety while reducing a plant costs and environmental impacts. Filtration can keep Oil clean and extend the life of plant components. Filtration helps plant processes to operate at the lowest possible cost and improves overall process efficiency. This means that equipment will be protected from unnecessary wear or pluggage, catalysts will be conserved, operations will experience less down time and product quality will be greatly improved.

Factors for Proper Oil Filter Selection

Structural Integrity - Arguably the most critical factor, structural integrity relates to a filter’s ability to prevent the passage of oil through an unfiltered flow path. The International Organization for Standardization (ISO) has established procedures for testing fabrication integrity, material compatibility, end load and flow fatigue. These tests can reveal defects such as improper sealing of seams and end caps or breaks in the media from high-flow conditions, as well as the effects of high temperatures on the filter element.

Contamination (Dirt-Holding) Capacity - This refers to the amount of contaminants that can be loaded onto the filter before the filter’s efficiency is limited.

Pressure Loss - This involves the overall differential pressure lost from the filter’s placement on the system. The pressure loss will be influenced by the filter media’s porosity and surface area.

Particle Capture Efficiency - This is the overall effectiveness of the filtration mechanisms within the filter media to extract and retain contaminants from the oil.

System/Environment - The characteristics of the system and environment in which the filter will be installed must be considered, including the contamination expectations, flow rates, location, vibration, etc.

Maintaining Installed Filters

The best way to prevent filters from reaching their dirt-holding capacity is to avoid contaminants in the system from the beginning. The fewer external contaminants that ingress, the fewer contaminants that are generated internally (particles produce particles). Use the following guidelines to maintain installed filters

Ensure proper breathers are installed to prevent contaminants and moisture from entering the system.
Keep seals and cylinders clean and dry by using appropriate wipers and boots.
Select the appropriate oil grade and additive package to counter contaminant ingression and internal friction.

Analysing the Filter

A filter not only is a trap for the machine’s undesirables but also a concentration of clues as to what’s occurring within the machine. Particles within the oil may be so highly diluted that practical analysis can become a daunting challenge. However, the particles trapped in the filter may be so plentiful that they can be easily visible to the naked eye. Metal contaminants are a primary indication of an issue within the machine. Although some amount of metal contaminants can be expected, an unusual amount should be recognized by trending the filter’s visual appearance after each oil change.


The Pall programme of Total Cleanliness Control provides a complete partnership to meet all related fluid filtration and service requirements.

This partnership enables our customers to achieve fluid cleanliness effectively and economically throughout, from the detection of contamination to the attainment of optimum system performance.

The TCC approach results in long term benefits to our customer including enhanced system reliability reduced maintenance costs, extension of fluid life and waste minimization and provide optimum equipment availability anywhere it is applied

One of the most effective tools to adopt Pall’s TCC approach is the ‘High efficiency Filtration System’ which can be used off-line of any hydraulic/lubrication system to achieve the desired oil cleanliness level and maintain it consistently


The PALL - High Efficiency Filtration system is a complete system with built-in pump, motor, filter with all other required accessories. It can be connected to any of the hydraulic /lube system reservoir as an offline unit and based on the oil volume it will give NAS Class 3 quality oil (ISO Code 14/11) and better in a short span of time.


Effective method of removing particulate contamination and maintaining desired oil cleanliness
level in the hydraulic/lube systems.
Filtration can be carried out when the system is shut-down.
Filter operation is independent of main system.
