Type of contamination and its effects
Effective fuel and oil management is vital to ensure the smooth operation of machinery and equipment in every industry. Failure to maintain clean fuel and oil can lead to numerous detrimental effects. This section delves into the key consequences of using contaminated fuel and oil.
| Type of Contaminants | Effects on Fuel and Oil | Effects on Engine Life | Effects on Environment |
|---|---|---|---|
| Particulate | Potential clogging in fuel injector | Likelihood of short engine life | Likelihood of short engine life |
| Water | Corrodes metal parts | Forms oxidation | Basis of acid rain and pollution |
| Chemical | Alteration in fuel properties | Corrosion of engine components | Responsible for air pollution and contributes to climate change |
| Metal Particles | Decrease fuel efficiency | Engine overheat, damage to fuel injectors | Risks to soil, crops and live stocks |
Understanding clean fuel and oil
Contaminant free fuel and oil is paramount to overall efficiency of engine and prolonging the lifespan of machinery. The ISO 4406 and NAS 1638 cleanliness codes offer standardized methods to evaluate fluid cleanliness. ISO 4406 provides three numerical values detailing the particle quantity in specific size ranges: 4 μm and larger, 6 μm and larger, and 14 μm and larger. In contrast, the NAS 1638 method differentially counts particles in size intervals of 5-15μm, 15-25μm, 25-50μm, 50-100 μm, and >100 μm.
For many equipment, an incoming cleanliness adhering to the ISO standard is typically 22/21/18. This indicates, for a 100ml fuel sample at an ISO level of 22, that there are between 2 to 4 million particles present. However, optimal machinery operation often requires a cleanliness closer to an ISO standard of 14/13/11. Utilizing KG Filter Carts guarantees high filtration efficiency, ensuring NAS level 4 clean oil. Ensuring such cleanliness levels significantly reduces wear and tear, providing optimal equipment performance and longevity.

|---|---|---|
| 24 | 8,000,000 | 16,000,000 |
| 23 | 4,000,000 | 8,000,000 |
| 22 | 2,000,000 | 4,000,000 |
| 21 | 1,000,000 | 2,000,000 |

What is bulk filtration and how does it work?
Bulk filtration is a comprehensive solution designed to remove contaminants from large quantities of fuel and oil, ensuring their cleanliness and optimal quality. This process involves the use of advanced filtration systems specifically designed for high-capacity applications. The bulk filtration process typically consists of multiple stages, each targeting different types of contaminants. KG Filter Cart uses SINGLE PASS FILTRATION technique to remove all contaminants and can be utilized in both in-plant machinery and mobile equipment. Below are the stages of KG Bulk Filtration systems:
- a. Main filtration in this stage, the fuel or oil flows through fine filtration media, such as high-quality filter cartridges. This stage consists of particulate filter designed to capture smaller particles, including those invisible to the naked eye, ensuring the fuel or oil is thoroughly purified.
- b. Water absorbing technology Water contamination is a common issue in fuel and oil systems. KG Filter Carts incorporate specialized technology to separate and remove free water from the fuel or oil.
Bulk filtration streamlines and expedites the cleaning process, offering a remarkably efficient solution. Traditionally, users would invest nearly half a day in cleansing equipment or storage tanks, incurring substantial labor expenses while grappling with operational downtime, untidy premises, and unsafe work conditions. KG International has ingeniously engineered systems for uninterrupted operation. These systems seamlessly integrate into prevailing fuel or oil storage and distribution frameworks, ensuring a smooth implementation devoid of any disruptive factors. The procedure of flushing is remarkably simple: insert the suction end of the hose at the tank’s inner base and the delivery end at a midpoint within the tank, initiate the pump and clean the entire tank within minutes.
Product range and use cases
KG Bulk Filtration solutions offer a diverse range of products that cater to unique demands, ensuring clean fuel and oil, improving equipment performance, and reducing overall maintenance costs. Every product in our range is meticulously crafted to fulfil these objectives. The use of premium-grade filter media guarantees high filtration efficiency and consistency in performance across multiple applications by effectively capturing particulate, water, and other contaminants. The pump used in the system is manufactured by an Italian company, PUS. With the capacity of 25 LPM, the pump can be used to filter Diesel, Lube Oil, Hydraulic or Gear Oil. A point to remember is when the liquid is changed, the filter needs to be changed as well.
