JY-DX40-L: Advanced Lubricant Filtration System Overview

I. Product Overview

1.1 Product Definition

The JY-DX40-L is a skid-mounted terminal precision guard filtration system engineered exclusively for independent lubricant manufacturers and OEM Lube Oil Blending Plants (LOBP). Positioned as the “last line of defense” between the blending kettle and the filling line, it guarantees absolute removal of harmful abrasive particles, agglomerates, and free water with an absolute retention rating of β₁₀ ≥ 200 before the oil is packaged. This ensures every batch consistently meets or exceeds the ultra-clean ISO 15/13/10 standards.

Unlike ordinary guard filters relying on traditional flexible media such as string-wound, melt-blown PP, or pleated paper elements, the JY-DX40-L utilizes the proprietary Jingyuan® Polymer Rigid Composite Membrane. This core industrial fluid purification technology entirely eradicates the four major pain points in high-viscosity lubricant filling scenarios:

• Zero Deformation: The rigid pore geometry remains entirely stable under cold-start shocks and pump pressure fluctuations, fundamentally eliminating the risk of “extrusion bypass.”
• Zero Fiber Shedding: The pore structure is solidified within the matrix, presenting zero risk of broken fibers shedding and contaminating the finished oil.
• Formula Protection: The pore size is strictly controlled within a 5–10 μm window. This optimally blocks harmful abrasive particles while safely allowing critical additive molecules, such as detergent-dispersant micelles and Viscosity Index Improvers (VII), to pass through intact.
• Non-Stop Production: A parallel three-valve bypass design ensures the filling line rhythm remains uninterrupted during backwashing and routine maintenance.

With a rated flow of 20–30 m³/h and suitability for medium-to-high viscosity lubricants (32–320 cSt), the system is equipped with a 7.5 kW low-shear gear pump to protect additive activity. Integrated into a 1680 kg skid with standard DN65 flanged connections, it seamlessly incorporates into existing filling lines, empowering high-end OEM plants to break through strict cleanliness barriers and build differentiated competitive advantages.

1.2 Addressing Core Pain Points

While most lubricant manufacturers possess robust capacities in the blending phase, traditional flexible media expose severe quality and efficiency vulnerabilities during the “final guard filtration” stage when handling 32–320 cSt medium-to-high viscosity fluids:

1.3 Value Proposition

The economic logic of the JY-DX40-L: A single capital investment in terminal precision filtration slashes batch rework rates from an industry average of 3.5% down to less than 0.5%, eradicating OEM return risks. The non-stop production design cuts unplanned filling line downtime by 80%. Consumable-free operation eliminates the dual costs of filter cartridge procurement and hazardous waste disposal. The quantifiable ISO 16889 report (β₁₀ ≥ 200) serves as the strongest commercial endorsement for breaking into high-end OEM supply chains, delivering an outstanding Total Cost of Ownership (TCO) advantage over traditional high-frequency cartridge replacement solutions.

II. Core Technology Analysis

2.1 Strict Pore Size Window (5–10 μm) — Blocking Abrasives While Protecting Formulas

The Unique Challenge of Lubricant Filtration: Unlike diesel or hydraulic oil conditioning, the core contradiction in lubricant filtration lies in the simultaneous presence of harmful abrasive particles (which must be intercepted) and critical additive molecules (which must be preserved):

• Detergent-dispersant micelle diameters generally range from 0.01 to 1 μm, while the hydrodynamic diameter of long-chain Viscosity Index Improvers (VII) can reach 2 to 5 μm.
• Harmful hard abrasive particles (metal shavings, oxide scales, environmental dust) are typically ≥ 5 μm.

While 1–3 μm filter media offer higher precision, they inevitably intercept VII and other critical additives, causing formula drift and viscosity index degradation—a result entirely unacceptable for high-end OEM finished oils.

The JY-DX40-L Solution: The Jingyuan® rigid membrane strictly restricts its pore size to a precise 5–10 μm window, featuring an absolute filtration ratio of β₁₀ ≥ 200 (ISO 16889). This means for every 200 particles ≥ 10 μm upstream, only 1 remains downstream (99.5% absolute retention). Harmful abrasives are entirely eradicated while all critical additive molecules pass through unharmed, achieving the ultimate balance between intercepting contaminants and protecting the effective formulation.

2.2 Rigid Membrane Zero Deformation & Zero Shedding — Absolute Safety for Filling Grades

Zero Extrusion Bypass: Cold starts and variable-speed pump pressure fluctuations are standard operating conditions on filling lines, causing sudden transmembrane differential pressure spikes. Under these shocks, ordinary soft filter media instantaneously expand their pores, allowing previously intercepted particles to “squeeze through” into the finished oil. Every pressure surge introduces a hidden batch quality risk.

The pore geometry of the Jingyuan® polymer rigid composite membrane is solidified within a high-strength sintered matrix (membrane wall thickness 3–5 mm). Across the entire operational range—from a normal working pressure drop of 0.2 MPa to the backwash trigger point of 0.5 MPa—the pore dimensions remain eternally constant. The absolute retention efficiency of β₁₀ ≥ 200 never degrades, regardless of differential pressure conditions.

Zero Fiber Shedding: Under high shear forces and long-term differential pressure, the breaking and shedding of micron-level fibers from string-wound and melt-blown media is physically inevitable. Once these shed fibers enter high-end OEM finished oils, the damage caused to precision components like servo valves and hydraulic lifters is immeasurable and notoriously difficult to trace.

Because the filtration channels are fixed via a sintering process into the polymer matrix, loose fibers physically do not exist. This eliminates secondary contamination at the source, serving as the most reliable quality endorsement a contract manufacturer can offer to OEM clients.

2.3 Intrinsic Superhydrophobic Water Removal — Mild Demulsification Without Separate Modules

Treated with a specialized chemical process, the surface of the membrane exhibits intrinsic superhydrophobic characteristics. It utilizes differences in interfacial tension to physically repel free and mildly emulsified water from the oil:

• Interfacial Tension Barrier: Due to variations in contact angles, water droplets are repelled and blocked by the membrane surface, preventing penetration to the clean oil side.
• Gravity Coalescence and Settling: The blocked water droplets coalesce into larger drops in low-velocity zones and settle into the water collection chamber at the bottom.
• Routine Drainage: Accumulated water is effortlessly removed by opening the bottom drain valve—no chemical demulsifiers required.

For mild cloudiness and emulsification issues caused by storage tank temperature differentials or pipeline condensation in LOBP filling lines, the JY-DX40-L accomplishes dehydration synchronously within the main filtration process. The system operates efficiently without the need for independent vacuum dehydration modules, drastically simplifying production line integration.

2.4 Three-Valve Parallel Bypass — Zero Production Downtime During Maintenance

Production continuity on lubricant filling lines is vital to a contract manufacturer’s output and delivery schedules. The JY-DX40-L comes standard with a Three-Valve Parallel Bypass Control Pipeline Design, ensuring the filling line never stops or slows down during gas-pulse backwashing or any maintenance operation:

III. Application Scenarios

3.1 High-End Anti-Wear Hydraulic Oil Filling Lines (HM / HV Series)

Applicable Products: Anti-wear hydraulic oils (ISO VG 32 / 46 / 68 / 100), high viscosity index hydraulic oils (HV), dedicated hydraulic fluids for high-end construction machinery and servo systems.

Typical Pain Points: Clearances in servo valves for high-pressure hydraulic systems (≥ 35 MPa) are typically less than 5–10 μm. A single hard particle ≥ 10 μm in the finished oil can trigger a servo valve jam. OEM manufacturers widely mandate ISO 16/14/11 or higher cleanliness levels, which ordinary guard filters struggle to maintain consistently. The cost of product returns and loss of OEM qualification far outweighs the capital expenditure of the purification equipment.

JY-DX40-L Advantages: An absolute retention rating of β₁₀ ≥ 200 ensures the finished hydraulic oil’s particle count is firmly locked at ISO 16/14/11, physically eradicating the risk of servo valve jamming. The quantifiable ISO 16889 test report acts as the strongest qualification endorsement for OEM audits. The non-stop design guarantees high-speed filling rhythms remain unaffected by filter maintenance.

Recommended Precision: 5 μm (Targeting ISO 16/14/11)
Installation Position: At the end of the blending kettle discharge pipeline, connected in series before the filling machine for full-flow guard filtration.

3.2 Industrial & Wind Power Gear Oil Filling Lines (VG 220–VG 680)

Applicable Products: Industrial enclosed gear oils (ISO VG 220 / 320 / 460 / 680), dedicated wind turbine gearbox lubricants, heavy-duty mining gear oils.

Typical Pain Points: Wind and mining equipment OEMs are enforcing increasingly strict gear oil particle count requirements, frequently demanding ISO 18/16/13 or higher. High-viscosity gear oils (220–680 cSt) cause traditional filter elements to experience rapid pressure surges, leading to exorbitant downtime frequencies. Agglomerated particles formed by incompletely dissolved additives during blending, if passed into the finished product, directly compromise gear surface protection and oil lifespan.

JY-DX40-L Advantages: A specialized 7.5 kW low-shear precision gear pump is engineered for high-viscosity media. It maintains stable flow rates under VG 320–VG 680 conditions without inflicting mechanical shear degradation on Extreme Pressure (EP) additives. The 10 μm precision window blocks harmful hard particles while permitting the active groups of EP and anti-rust additives to pass flawlessly. Dynamic viscosity compensation ensures consistent filling velocities across different seasons (where temperature shifts significantly impact viscosity).

Recommended Precision: 10 μm (Targeting ISO 18/16/13)
Installation Position: Blending kettle discharge pipeline for high-viscosity gear oils, series-connected prior to filling.

3.3 Passenger Car Motor Oil Filling Lines (SN / SP / GF-6 Specs)

Applicable Products: Fully synthetic / semi-synthetic engine oils (0W-20 / 5W-30 / 5W-40, etc.), API SP / ILSAC GF-6 specifications.

Typical Pain Points: Fully synthetic engine oils possess high concentrations of detergent-dispersants, VIIs, and friction modifiers, demanding supreme chemical inertness from filter media. Any chemical interaction between the media and active additive components can result in formula drift, jeopardizing the finished oil’s certified drain intervals. Component-level engine OEMs conduct rigorous spot checks on additive concentrations in batch oils; any formula loss immediately triggers supplier qualification reviews.

JY-DX40-L Advantages: Jingyuan® polymer membrane materials undergo deep chemical inertness treatments. Devoid of polar static charges, the membrane does not electrostatically adsorb detergent-dispersant micelles (0.01–1 μm), preserving the formula composition entirely. The 5 μm precision window achieves ≥ 99.5% retention of harmful abrasives ≥ 5 μm while granting passage to all functional additive molecules. The finished oil particle count stably achieves the ISO 17/15/12 level, fulfilling the stringent matching requirements of top-tier passenger vehicle OEMs.

Recommended Precision: 5 μm (Targeting ISO 17/15/12)
Installation Position: Guard filtration node between the blending kettle and the automated filling line.

3.4 Plant-Wide Consumable-Free Upgrades for Lubricant Contract Manufacturers

Applicable Scenarios: Comprehensive lubricant contract manufacturers (O&M) executing systematic terminal guard filtration upgrades across all production lines. The goal is to achieve “consumable-free operations” and comprehensively replace traditional disposable cartridge filters.

Typical Pain Points: Contract manufacturing product lines span multiple viscosity grades and specifications. Traditional setups require dedicated filter cartridge models for each line, creating complex SKU management and massive spare part inventory pressure. Annual expenditures on cartridge procurement and hazardous waste disposal of oil-soaked filters accumulate into the hundreds of thousands. As OEM clients tighten cleanliness standards, traditional disposable cartridges can no longer guarantee quantifiable and repeatable cleanliness across all lines.

VI. Customer Success Story: Lubricant Blending and Terminal Filling

6.1 Pain Points and Challenges

Prior to introducing the Jingyuan filtration system, the client was battling immense quality pressures brought on by high-capacity production:

• Quality Compliance Challenges: Finished oils lacking precision filtration exhibited visible and microscopic impurities, resulting in highly fluctuating particle count metrics. OEM clients enforce excruciatingly strict cleanliness standards that traditional filtration systems struggled to consistently meet (e.g., ISO 15/13/10).
• High Filling Line Attrition: Micron-level hard particles frequently caused severe wear on precision filling valves, generating dripping, inaccurate metering, and exorbitant annual unplanned maintenance expenses.
• Skyrocketing Batch Rework Costs: Once a spot check revealed elevated particle counts, thousands of liters of oil per tank had to be back-flushed and reprocessed, inflicting massive wastes in energy and time.

6.2 Solution and System Configuration

The client initially deployed a single JY-DX40-L skid-mounted precision filtration system for on-site validation, integrated into the online/circulation filtration loop between the blending kettle discharge and the automated filling line. Leveraging its rated large flow capacity of 20–30 m³/h, the system efficiently handled varying blending tank scales to process hydraulic oils, gear oils, transmission fluids, and specialty industrial oils. To satisfy the relentless retention demands of high-end OEMs, the system utilized a 5 μm absolute precision configuration (β₁₀ ≥ 200).

Deployment Logic: The pilot unit aimed to verify whether absolute filtration technology could instantly elevate particle counts to OEM standards without impeding blending efficiency. Within the first week of operation, the unit demonstrated such superior purification efficiency that previously borderline-failing batches achieved instant compliance, directly salvaging potential rework losses. Driven by this immediate Return on Investment (ROI), the client swiftly placed additional orders, deploying a total of 4 units to achieve comprehensive coverage across all core production lines.

6.3 Core Benefits

By implementing the JY-DX40-L system across all lines, the manufacturer achieved absolute production standard consistency.

• Leap in Cleanliness: Particle counts stably plummeted from ISO 21/19/16 down to ISO 15/13/10.
• Dual Optimization in Efficiency and Maintenance: The batch rework rate due to non-compliant oil plunged by 95%. Simultaneously, the replacement frequency of precision filling nozzles decreased by 30%.
• Significantly Enhanced Brand Premium: The maintenance team reported a drastic drop in filling line failure rates. More importantly, they are now equipped to provide certified cleanliness reports alongside high-quality products to any high-end OEM client, remarkably bolstering their brand’s premium pricing power.

📈 Core Metrics Overview: Following stable system operation, outgoing oil particle counts leaped from ISO 21/19/16 to ISO 15/13/10, triggering a cliff-like drop in batch rework rates to under 0.2%. Concurrently, unplanned equipment downtime was slashed by over 80%, yielding a structural reduction of roughly 30% in annual comprehensive maintenance costs per filling machine.

VII. Frequently Asked Questions

Q1: Will the 5–10 μm precision restriction affect the passage of critical additives like detergent-dispersants and VIIs in the lubricant?

A: No, and this is exactly the core logic behind the JY-DX40-L’s pore window design. The diameter of detergent-dispersant micelles is typically 0.01–1 μm, and the hydrodynamic diameter of long-chain Viscosity Index Improvers (VII) is roughly 2–5 μm—both significantly smaller than the minimum 5 μm pore size, allowing them to pass through completely. Furthermore, the Jingyuan® polymer membrane surface undergoes deep chemical inertness treatment. Devoid of polar static charges, it exhibits no electrostatic adsorption towards these polar active molecules. It is only filter media with pores that are too small (e.g., 1–3 μm) that will intercept VIIs and alter formula compositions. The JY-DX40-L’s 5–10 μm window achieves the ultimate balance between “intercepting abrasives” and “protecting the formula.”

Q2: When facing OEM commercial bidding, what is the substantive difference between β₁₀ ≥ 200 and a “nominal 10 μm precision”?

A: The difference is fundamental. “Nominal 10 μm” is merely an unverified manufacturer claim lacking a standardized testing basis; actual retention rates in the industry often fall below 50%. The β₁₀ ≥ 200 metric is based on the ISO 16889 Multi-Pass Test—the globally recognized standard for quantitatively evaluating filtration efficiency in hydraulic and lubrication industries. Its implication is profound: for every 200 particles ≥ 10 μm upstream, only 1 remains downstream, translating to a 99.5% absolute retention efficiency. Submitting a Beta ratio testing report to a multinational OEM is equivalent to presenting a quantified data commitment: “Equipped with our system, the number of ≥ 10 μm hard particles in the initial factory fill oil is reduced by at least 200 times compared to ordinary filter bags.” This is the universal language for breaking OEM entry barriers; it is verifiable proof of technical capability, not a simple marketing pitch.

Q3: When switching to Bypass V3 during backwashing, is the quality of the oil filled during that time still guaranteed?

A: This is a management issue that requires clear definition within the factory’s quality system. During the time V3 is open, the oil bypasses the JY-DX40-L precision filtration and directly enters the filling machine; therefore, the β₁₀ ≥ 200 cleanliness guarantee cannot be provided. Suggested handling methods: ① A single gas-pulse backwash takes a very short time (5–15 minutes) and can be scheduled during batch intervals (changing drums or tanks) to avoid affecting official product batches. ② If performing a backwash mid-production is unavoidable, products filled during that bypass period should be marked and segregated, to be released only after passing third-party particle count testing. ③ For product lines with the strictest cleanliness requirements (e.g., high-pressure hydraulic oil), we recommend configuring two JY-DX40-L units in a mutually redundant setup to ensure one unit is always providing precision filtration.

Q4: Is there a risk of the 7.5 kW gear pump causing shear degradation to lubricant additives?

A: The risk is extremely low and practically negligible. The shearing mechanism in a gear pump originates from short-duration shear in the gear meshing zone, which is fundamentally different from dedicated shearing equipment like high-speed homogenizers or colloid mills. The precision gear pump equipped on the JY-DX40-L features an extremely low linear shear rate and high volumetric efficiency, maintaining the fluid safely within the laminar flow regime inside the pipes. Mechanical shear degradation of high-polymer additives like VII typically occurs at high-speed centrifugal pumps or specific high-pressure throttling components. Within the JY-DX40-L’s normal working pressure range of 0.2–0.35 MPa, the gear pump will not inflict measurable shear degradation on conventional lubricant formula components.

Q5: How can we execute a “three-step” production line upgrade validation to obtain quantifiable ROI data before a factory-wide rollout?

A: We recommend the following proven implementation path: Step One: Fluid Full-Link Audit—Commission a third party to collect oil samples from three nodes: the blending kettle outlet, intermediate pipelines, and right before the filling head. Test the particle counts according to ISO 4406 to identify the “node with the highest contamination increment” and precisely pinpoint the installation location. Step Two: Single-Line Pilot Validation—Deploy a single JY-DX40-L unit on the product line with the highest cleanliness requirements (e.g., high-end anti-wear hydraulic oil). Run a pilot for two weeks, retaining samples of daily filling batches, and submit them to a third-party lab to compare Before / After particle count reports. Simultaneously record O&M data like downtime frequency, backwash frequency, and waste liquid volume. Step Three: ROI Calculation & Factory-Wide Rollout—Utilize the pilot data to quantify metrics such as annual reduced downtime, decreased rework rates, and saved consumable costs to calculate the true ROI. Use this data as the foundation to apply for a factory-wide deployment budget.

Q6: What is the lifespan of the entire machine? Do the membrane modules need to be replaced?

A: The design lifespan of the skid-mounted main body (pump group, housing, pipelines, instruments) is equivalent to industrial-grade fixed equipment, comfortably operating for over 10 years under normal maintenance conditions. The Jingyuan® membrane modules possess a design lifespan of ≥ 3 years and can be used continuously until the end of their lifecycle under standard operating conditions (temperature ≤ 80°C, regular gas-pulse regeneration). When the lifespan expires or mechanical damage occurs, the membrane modules can be replaced independently without scrapping the entire machine, preserving your capital investment in the skid structure. Early warning signals for replacement: The pressure drop recovery rate consistently remains below 80% after multiple deep cleanings, or spot checks reveal visible cracks on the membrane body.

Q7: What is the difference between the JY-DX40-L and the JY-DX40-W (Petroleum Re-refining Edition)? How do I choose?

A: Both belong to the Jingyuan® DX40 series and share the core rigid membrane technology, but they are optimized for entirely different application scenarios. The design focus of the JY-DX40-L (L = Lubricant) is “Formula Protection + High-End OEM Cleanliness Compliance.” Its 5–10 μm pore window is engineered specifically to protect the integrity of additive molecules, its 7.5 kW low-shear gear pump protects additive activity, and the three-valve bypass ensures continuous filling line production. Its target customers are lubricant manufacturers and contract plants. The design focus of the JY-DX40-W (W = Waste oil Re-refining) is “Heavy-Duty Filtration under High-Temperature, High-Pressure, and Highly Corrosive Complex Conditions.” It adopts a 304L stainless steel Wedge Wire structure, withstands temperatures up to 200°C, and adapts to waste oil re-refining, acid washing, and hydrogenation processes. Its target customers are petrochemical refineries. Selection principle: Finished Lubricant Filling → JY-DX40-L; Waste Oil Re-refining Processes → JY-DX40-W.
