LYC High-Precision Oil Purifier – Hydraulic Oil Series Mobile Offline Filtration Solution for Hydraulic System Maintenance

Product Performance & Technical 

HighlightsHydraulic Oil Optimized Design

The LYC purifier is purpose-tuned for hydraulic oil working conditions, accommodating conventional viscosity grades without stripping or

 degrading the original additive package. This ensures that oil performance characteristics—such as anti-wear properties, oxidation stability, 

and demulsibility—remain intact throughout the filtration process.

Graded High-Precision Filtration

The system integrates a progressive filtration train, from coarse pre-filtration to high-efficiency fine polishing stages, effectively intercepting

 particulate contaminants down to the micron level. This graded approach not only optimizes filter element service life but also stabilizes 

the oil's ISO cleanliness code, providing robust protection for hydraulic precision components including servo valves, piston pumps, 

and proportional actuators.

Compact & Ergonomic Mobility

Equipped with heavy-duty universal casters and a space-saving structural design, the LYC purifier can be easily maneuvered by a single operator. 

This mobility enables rapid deployment across multiple workstations, hydraulic power units, and field service locations, significantly enhancing

 operational flexibility and reducing equipment idle time.

Built-in Overload & Overflow Dual Safety Protection

The system incorporates dual safety mechanisms—motor overload protection and hydraulic overflow protection—to safeguard both the purifier

 and the connected hydraulic circuit under abnormal operating conditions. The unit operates with low noise emission and supports extended 

continuous duty cycles, ensuring reliable performance even during prolonged filtration campaigns.

Technical Specifications & Construction Features

*Industrial-Grade Gear Pump

Fitted with a high-performance industrial gear pump, the LYC purifier delivers strong self-priming capability and stable, pulsation-free flow output. 

This robust pumping system accommodates large-volume circulation filtration requirements while maintaining consistent pressure and flow 

characteristics across varying oil viscosities.

*Durable Frame Construction

The main frame is fabricated from corrosion-resistant carbon steel with a durable anti-rust coating, providing reliable service in both indoor 

workshops and demanding outdoor environments. This rugged construction ensures long-term structural integrity and resistance to mechanical impact, 

moisture, and chemical exposure.

*Differential Pressure Indicator

A built-in differential pressure indicator provides real-time visual feedback on filter element loading status. 

This allows maintenance personnel to promptly identify saturated or clogged elements and schedule timely replacement, preventing

 bypass valve activation and ensuring continuous filtration efficiency.

Standard 380V Industrial Power Supply

Powered by a standard 380V industrial power supply, the LYC purifier features a rationally matched motor that balances energy 

efficiency with output performance. The motor supports frequent start-stop operations without compromising service life, 

making it suitable for intermittent or batch filtration tasks common in maintenance workflows.

Scope of Application

The LYC High-Precision Oil Purifier is primarily deployed for oil filtration and purification in the following hydraulic systems:

· Hydraulic power stations and centralized hydraulic supply units

· Machine tool hydraulic systems, including CNC machining centers, grinding machines, and injection molding equipment

· Construction machinery hydraulic circuits, such as excavators, loaders, and cranes

· Hydraulic pump stations and servo drive systems

While specifically engineered for hydraulic oil purification, the LYC series is also well-suited for filtration and regeneration of lubricating oils 

with similar viscosity grades, including gear oils and circulating oils used in industrial gearboxes and bearing lubrication circuits.

Operational Benefits & Economic Value

*Extended Oil Service Life

By continuously removing particulate contaminants and maintaining oil cleanliness within specified ISO targets,

 the LYC purifier significantly extends hydraulic oil drain intervals. This directly translates into reduced fresh oil procurement costs and minimized 

hazardous waste oil generation.

*Reduced Component Wear & Downtime

Clean hydraulic oil reduces abrasive wear on pumps, valves, cylinders, and bearings, lowering the frequency of unscheduled maintenance and

 component replacement. The resulting improvement in system reliability contributes to higher overall equipment effectiveness (OEE) and reduced 

production interruptions.

*Versatile Deployment & Asset Optimization

A single LYC purifier can serve multiple hydraulic systems within a facility, eliminating the need for dedicated fixed filtration units at each workstation.

 This optimized asset utilization delivers a rapid return on investment while simplifying maintenance logistics.

*Environmentally Responsible Fluid Management

The LYC purifier supports sustainable fluid management practices by enabling on-site oil reclamation and reducing the volume of spent oil requiring 

off-site disposal. This aligns with corporate environmental goals and helps manufacturing facilities comply with increasingly stringent waste oil

 regulations.

Important Selection & Operation Guidance

*Filter Element Selection

Select the appropriate filter element micron rating based on the target cleanliness level required by your hydraulic system. For most industrial 

hydraulic applications, we recommend elements with βₓ≥200 (multi-pass efficiency) to achieve reliable contamination control.

*Pre-Operation Inspection

Before each operation, inspect all hoses, quick-connect couplings, and sealing gaskets for signs of wear or damage. Ensure that the suction line is

 properly submerged in oil to prevent air ingestion and pump cavitation.

*Maintenance Scheduling

Replace filter elements when the differential pressure indicator reaches the designated alarm zone, rather than adhering to rigid calendar-based 

schedules. This condition-based maintenance approach maximizes filter life while ensuring consistent filtration performance.

*Oil Sampling & Monitoring

Utilize the built-in sampling port to conduct regular oil analysis (particle count, viscosity, water content, and acid number). 

This data-driven approach enables predictive maintenance and provides objective evidence of filtration effectiveness.

Frequently Asked Questions

Q1: Can the LYC purifier handle high-viscosity hydraulic oils?

A1: Yes. The industrial gear pump and flow circuitry are designed to accommodate conventional hydraulic oil viscosity grades. 

For extremely high-viscosity fluids, please consult our technical team for specific recommendations.

Q2: Does the filtration process remove beneficial oil additives?

A2: No. The graded filtration media are specifically selected to target solid particulates while allowing dissolved additive molecules to pass through 

unaffected. Your oil's anti-wear, anti-oxidant, and anti-foam additive packages remain fully intact.

Q3: Is operator training required for installation and use?

A3: Basic hydraulic system familiarity is sufficient. The LYC purifier features intuitive controls and clear visual indicators. 

We also provide comprehensive operation manuals and optional on-site training upon request.

Q4: Can this unit be customized for special voltage or flow requirements?

A4: Yes. We offer customization services for motor voltage, pump flow rate, filter element grades, and frame configuration to suit specific 

application needs. Please contact our technical sales team for tailored solutions.
