Types Of Hydraulic Oil Purifier Systems
Offline Filtration Systems
Offline filtration systems function autonomously from the primary hydraulic circuit, offering continuous filtration and maintenance capabilities without disrupting system operation. These systems typically consist of dedicated filtration units equipped with their own pumps, filters, and reservoirs. By operating independently, offline systems can target specific areas or components within the hydraulic system that require intensive filtration, ensuring thorough contaminant removal without affecting overall system performance.
Inline Filtration Systems
Inline filtration systems are seamlessly integrated into the main hydraulic circuit, filtering hydraulic oil as it flows through the system. These systems are designed to remove contaminants in real time, preventing their accumulation and safeguarding system components from wear and damage. Inline filters are strategically installed at critical points within the hydraulic system, such as before sensitive components or after high-wear areas, ensuring comprehensive filtration coverage.
Kidney Loop Filtration Systems
Kidney loop filtration systems utilize a dedicated loop within the hydraulic circuit to recirculate a portion of hydraulic oil through a specialized filtration unit. This dedicated loop, often called the “kidney loop,” allows for enhanced hydraulic fluid filtration, targeting specific contaminants and maintaining oil cleanliness levels beyond what inline filtration systems can achieve alone. Kidney loop systems are particularly beneficial for critical components or systems requiring ultra-clean oil, such as high-precision machinery or hydraulic systems operating in harsh environments. Kidney loop systems contribute to prolonged equipment lifespan and improved system reliability by continuously purifying a portion of the hydraulic fluid.
Mobile Filtration Units
Mobile filtration units offer versatility and convenience for on-site filtration applications, catering to equipment servicing needs in remote locations or during maintenance operations. These portable units are equipped with filtration equipment, pumps, and reservoirs, allowing them to be transported and deployed wherever needed. For example, in a construction site where heavy machinery is used, a mobile filtration unit can be brought in to maintain the cleanliness of the hydraulic systems. Mobile filtration units provide a practical solution for maintaining hydraulic system cleanliness when access to centralized filtration systems may be limited or impractical. Whether servicing equipment in the field or conducting maintenance operations in challenging environments, mobile filtration units offer flexibility and efficiency in ensuring hydraulic system integrity and performance.
After each use of this device, when using it again:
- Check for air leaks and tighten bolts if necessary.
- Check whether the electrical parts on the instrument panel are loose.
- Check that the points of each meter head should not be loose.
- Check that each valve has a good start.
- The vacuum pump oil level should be on the red line. In another word, make sure it is normal.

Components Of Hydraulic Oil Purifier
Filters
Filters are the frontline defense against contaminants in hydraulic systems. They are available in various types, each designed to tackle specific pollutants. For instance, depth filters effectively capture larger particles, while surface filters excel at trapping finer contaminants.
Filter Housings
Filter housings serve as protective enclosures for filters, ensuring proper functioning and preventing oil bypass. These housings provide structural support to filters, safeguarding them against damage from pressure fluctuations and external impacts. Additionally, they facilitate easy installation and sealing of filters, minimizing the risk of leaks, and maintaining filtration effectiveness.
Valves and Gauges
Valves and gauges are integral components of hydraulic oil filtration systems, responsible for monitoring and controlling oil flow and pressure. Valves regulate hydraulic oil flow through the filtration system, ensuring optimal filtration rates while maintaining system pressure. They act as the ‘traffic controllers’ of the system, ensuring that the right amount of oil is flowing through the filters at all times. Gauges, on the other hand, provide real-time feedback on pressure levels and filter conditions, enabling operators to identify potential issues and take corrective actions promptly. By maintaining proper oil flow and pressure, valves and gauges contribute to hydraulic systems’ efficient operation and longevity.
Bypass Systems
Bypass systems are safety features designed to ensure the continuous operation of hydraulic systems, even in the event of filter clogging. When filters become overly saturated with contaminants, bypass systems divert oil flow away from the obstructed filters, allowing uninterrupted operation. This is particularly useful in situations where a filter is clogged and needs to be replaced, but the system cannot be shut down. While bypass systems prevent system shutdowns, it is important to note that oil passing through bypasses may not undergo filtration, leading to reduced overall filtration efficiency. Therefore, regular filter condition monitoring and timely filter replacement are crucial for maintaining optimal filtration performance and preventing excessive reliance on bypass systems.
