What is kidney loop filtration?

Kidney loop oil filtration is an oil filtration method used to clean and maintain the quality of oil in machinery and equipment. It operates by diverting a portion of the oil from the main system into a separate filtration loop. Within this loop, the oil passes through various filtration mechanisms. These filters remove contaminants such as dirt, metal particles, and moisture from the oil, ensuring that it remains clean and free of impurities. After filtration, the cleaned oil is returned to the main system, contributing to prolonged equipment life, improved performance, and reduced maintenance costs. 

The continuous circulation and purification of oil through the kidney loop system help maintain optimal lubrication properties, mitigate wear and tear, and extend the lifespan of machinery components, making it a vital aspect of industrial maintenance practices.

Neptunus’ Kidney Loop Oil Filtration System

Kidney loop filtration systems, also known as offline filtration systems, draw oil from the oil reservoir and deliver it back to the reservoir after filtration. This helps in enhancing efficiency as it operates under below-ideal conditions such as reduced flow, minimal pressure, and no stress from flow and pressure pulsations.

Its continuous operation guarantees uninterrupted equipment functionality, reducing downtime and maintenance costs while extending the lifespan of critical assets. With Neptunus’ innovative technology, industries can rely on consistently clean oil for enhanced productivity and reliability in their operations

Kidney Loop Filtration System vs. Online Filtration System

Kidney Loop Filtration System Online Filtration System
Process Circulates a small amount of fluid from the main system through a filter and back into the main system. Filters and cleans fluids in real-time as they are being used.
Impact On Machine Does not hinder the equipment’s operation. Causes resistance for oil flow to equipment’s internal components.
Damage To Machine The offline filtration system doesn’t cause resistance to oil flow inside equipment’s internal components. Damage to the filtration system or choking of filters can cause oil starvation and seize the equipment.
Type It is an offline filtration system. It is an online filtration system.

Process of Kidney Loop Oil Filtration System

The working principle of a kidney loop oil filtration system involves diverting a portion of the oil from the main reservoir, passing it through specialized filtration mechanisms, and returning it to enhance machinery reliability and longevity. The detailed process of the kidney loop (offline) filtration system is as follows:

Step 1: Oil Extraction

The kidney loop filter system begins by drawing a portion of the oil from the main reservoir or sump of the machinery using a pump or other extraction mechanism.

Step 2: Filtration

The extracted oil is then passed through filtration components such as micron filters. These filters are designed to remove contaminants such as dirt, metal particles, water, and other impurities from the oil.

Step 3: Contaminant Separation

Within the filtration system, various techniques are employed to separate contaminants from the oil.

Step 4: Particle Retention

The filtration process traps contaminants within the filter media, preventing them from re-entering the oil stream.

Step 5: Oil Analysis

Some kidney loop filtration systems incorporate an oil condition monitoring system with sensors to monitor and assess the cleanliness and quality of the filtered oil. This step helps in determining the effectiveness of the filtration process and identifying any potential issues with the machinery.

Step 6: Return of Clean Oil

After filtration, the cleaned oil is returned to the main reservoir or sump of the machinery, where it can continue to lubricate and protect the various components.

Step 7: Continuous Circulation

The kidney loop filtration system operates continuously, constantly circulating a portion of the oil through the filtration process to maintain optimal cleanliness and quality.
