LYC high-precision hydraulic oil purifier – mobile, multi-stage filtration, extends oil life.

Product Overview

The LYC High-Precision Oil Purifier is a mobile, integrated oil purification unit

 specifically engineered for hydraulic systems across industrial applications.

 Designed to remove solid particulates and dust contaminants from hydraulic oil with

 exceptional efficiency, this purifier employs a graded filtration architecture that rapidly

 improves oil cleanliness to prescribed ISO standards.

Whether you are filling new oil into a clean system, performing bypass offline filtration 

during production, or regenerating used oil for extended service, 

the LYC purifier delivers reliable, consistent performance. 

Its compact footprint and mobility make it an indispensable tool for daily maintenance 

programs in manufacturing plants, construction sites, and heavy equipment workshops.

Unlike stationary filtration systems that require dedicated installation and piping modifications, 

the LYC purifier connects quickly to any hydraulic reservoir or circulating loop via flexible hoses. 

It operates independently without interfering with normal equipment function, 

enabling convenient "kidney-loop" purification that keeps your hydraulic fluid clean

 while your machinery continues running.

2. Product Performance – Engineered for Hydraulic Systems

Optimized Filtration for Hydraulic Oil

The LYC purifier is purpose-designed for hydraulic oil working conditios. 

It accommodates conventional hydraulic oil viscosity grades without degrading

 or depleting original oil additives. This ensures that while contaminants are

 aggressively removed, the oil's chemical composition, anti-wear properties, 

and viscosity remain intact – preserving the fluid's full service life and performance

 characteristics.

Graded High-Precision Filtration

The purifier adopts a multi-stage graded filtration system that progressively removes

 contaminants from large to sub-micron sizes. The coarse stage intercepts larger particles

 and debris, protecting downstream fine filters from premature loading. 

The high-efficiency fine stage captures minute solid contaminants that would otherwise 

circulate through and erode hydraulic precision components such as servo valves, piston pumps,

 and proportional valves.

By stabilizing oil contamination levels within acceptable limits, 

the LYC purifier directly contributes to reduced component wear,

 fewer unscheduled breakdowns, and extended equipment overhaul intervals.

Compact & Mobile Design

Equipped with heavy-duty universal casters and a space-saving structural design, 

the LYC purifier is easily maneuverable by a single operator. It can be quickly repositioned 

to serve multiple hydraulic stations, machine tools, or construction machinery within a 

workshop or across a job site – eliminating the need for dedicated filtration units at every location.

Safety & Reliability

Built-in overload protection and overflow safety valves provide dual-layer security against 

abnormal operating conditions. The motor is protected from current surges,

 while the hydraulic circuit prevents pressure build-up that could damage the pump 

or filter elements. These features, combined with low-noise operation, 

support extended continuous working periods without supervision.

3. Technical Conditions – Robust Construction for Demanding Environments

Industrial-Grade Pump Assembly

The LYC purifier is powered by an industrial gear pump renowned for strong self-priming 

capability and stable flow output even under varying inlet conditions.

 This ensures consistent filtration performance regardless of oil temperature or viscosity

 fluctuations, meeting the demands of large-volume circulation filtration required by high-capacity hydraulic systems.

Durable Frame Construction

The main frame is fabricated from anti-corrosion carbon steel, finished with a rust-proof

 coating that withstands challenging indoor and outdoor environments. 

Whether operating in a humid factory, dusty construction site, or exposed workshop,

 the LYC purifier maintains its structural integrity and appearance over years of service.

Differential Pressure Indicator

A prominently mounted differential pressure indicator provides real-time visual feedback on

 filter element condition. When the indicator signals rising pressure differential, 

operators know it is time for maintenance – preventing bypass valve opening or filter rupture. 

This simple but crucial feature enables condition-based maintenance rather than fixed-interval 

changes, optimizing consumable life and reducing waste.

Standard 380V Industrial Power

The purifier operates on standard 380V industrial power supply, with a motor power rating

 matched to the pump's requirements for efficient energy consumption. The configuration

 supports frequent start-stop cycles common in mobile maintenance operations without

 compromising motor life or performance.

4. Scope of Application

Primary Applications

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

· Hydraulic power stations and centralized hydraulic pump stations

· CNC machine tool hydraulic systems

· Construction machinery hydraulic circuits (excavators, loaders, etc.)

· Injection molding machine hydraulic systems

· Metal forming and pressing equipment

Additional Applications

Beyond hydraulic oil, the LYC purifier is also suitable for filtration and regeneration of

 lubricating oils with viscosity grades similar to hydraulic fluids. This includes gearbox lubricants, 

circulating system oils, and certain turbine oils, offering versatility across multiple fluid types

 within the same facility.

Typical Use Cases

Scenario Application

New oil pre-filtration Remove contaminants introduced during storage and transport before 

filling clean systems

In-service oil maintenance Periodic kidney-loop filtration to keep oil cleanliness within ISO 

targets

Post-maintenance flushing Clean hydraulic circuits after component replacement or system

 overhaul

Oil regeneration Extend used oil service life by removing accumulated contaminants without

 replacing fluid

5. Economic & Operational Benefits

Cost Reduction

By extending hydraulic oil service life, the LYC purifier dramatically reduces new oil purchase

 frequency. Fewer oil changes also lower the volume of used oil requiring disposal – a growing

 expense in regions with stringent environmental regulations.

Extended Component Life

Clean hydraulic oil significantly reduces wear in pumps, valves, actuators, and seals. 

The LYC purifier's high-precision filtration ensures that abrasive particles are removed before 

they can damage critical surfaces, translating to longer component service intervals and lower

 spare parts consumption.

Reduced Downtime

Contamination-related hydraulic failures are a leading cause of unplanned downtime in 

manufacturing and construction. Regular use of the LYC purifier minimizes these incidents, 

keeping production lines running and projects on schedule.

Improved Asset Utilization

The mobile design allows one LYC purifier to serve multiple machines and systems, 

spreading its cost across a broader asset base and delivering higher return on investment 

compared to fixed-installation alternatives.

7. FAQ

Q1: What oil viscosity grades does the LYC purifier support?

A1: It handles conventional hydraulic oil viscosities as well as lubricating oils with similar

 viscosity ranges. For specific viscosity requirements, please consult our technical team.

Q2: How often should filter elements be replaced?

A2: Replacement is recommended when the differential pressure indicator signals a rise to 

the designated change level, rather than on a fixed time schedule. This condition-based 

approach maximizes filter life and minimizes waste.

Q3: Can this unit operate in outdoor environments?

A3: Yes. The anti-corrosion carbon steel frame with rust-proof coating makes it suitable for 

outdoor use, provided that electrical connections comply with site safety requirements.

Q4: Is installation complex?

A4: No. The LYC purifier connects via flexible hoses with standard fittings. No permanent 

plumbing modifications or foundation work are required – simply position, connect, and start.

Q5: Does filtration remove water from hydraulic oil?

A5: The standard LYC model focuses on solid particle removal. For applications requiring 

water separation, please enquire about our optional coalescing dehydration module.
