Portable High-Precision LYC-63B Explosion-Proof Oil Filter

The LYC-63B is a state-of-the-art, portable high-precision explosion-proof oil filtration system

 engineered for hydraulic and lubrication systems across a broad spectrum of industries. 

Designed to deliver exceptional fluid cleanliness, this unit effectively removes solid particulate 

contaminants from hydraulic oil, lubricating oil, and other industrial fluids, thereby extending

 the service life of hydraulic components, reducing wear, and optimizing overall system 

performance. Whether employed for routine maintenance of new oil, purification of oil in 

active systems, or cost-effective recovery of used oil, the LYC-63B stands as a versatile and 

indispensable solution for modern fluid management.

One of the standout features of this oil filter is its ability to operate independently from the 

main hydraulic system, serving as a bypass filtration unit. This allows for continuous, 

offline cleaning without interrupting primary operations. The unit is engineered for exceptional 

filtration precision, offering interchangeable filter elements with nominal ratings of 3μm, 5μm, 

10μm, 20μm, 30μm, and 40μm. Users can effortlessly switch between different filtration grades 

to achieve their desired cleanliness level, tailoring the unit's performance to specific application 

requirements. With its compact, mobile design and rugged construction, 

the LYC-63B is equally suitable for workshop use, field servicing, and mobile maintenance fleets.

Technical Parameters

The LYC-63B series is powered by a specially designed gear pump, directly coupled to a

 high-efficiency electric motor. This pump configuration is renowned for its low operational noise,

 strong self-priming capability, and exceptionally smooth running characteristics—even under

 varying fluid viscosities and operating pressures. The high-pressure circuit is equipped with 

an integrated overflow protection valve, which safeguards the hydraulic system against pressure 

surges and ensures safe, reliable operation under all working conditions. Additionally, 

the motor is protected by a thermal overload relay, which automatically shuts down the unit

 in the event of excessive current draw, preventing motor burnout and prolonging equipment life. 

The machine is built to handle a wide range of industrial fluids and operates effectively in 

demanding environments, with a sturdy base frame and casters for easy maneuverability.

Performance Characteristics and Advanced Design

1. Robust All-Steel Enclosure for Harsh Environments

The LYC-63B features a refined, heavy-duty steel shell that fully encloses all internal 

components—pump, motor, valves, and piping. This protective housing shields the

 filtration system from external contaminants such as dust, moisture, and mechanical impacts, 

making it particularly suitable for use in demanding environmental conditions, 

including outdoor sites, mining operations, and chemical plants where airborne particulates or 

explosive atmospheres may be present. The explosion-proof design complies with relevant 

safety standards, ensuring peace of mind in hazardous zones.

2. High-Efficiency Gear Pump Assembly

At the heart of the system lies a precision-machined gear pump, driven directly by the motor. 

This assembly is engineered for quiet, vibration-free operation, minimizing noise pollution in 

the workplace. Its strong self-priming ability ensures rapid start-up and consistent flow rates, 

even when drawing oil from remote reservoirs or through long suction lines. The pump's robust 

construction guarantees long service intervals and minimal maintenance.

3. Integrated Over-Pressure Protection

The high-pressure side of the system incorporates a reliable overflow (relief) valve. 

This protective device automatically diverts flow back to the inlet when system pressure exceeds

 a preset limit, preventing damage to the pump, filter elements, and downstream hydraulic

 components. This feature is critical for maintaining system integrity during cold starts, 

when oil viscosity is high, or when filter elements become progressively clogged.

4. Thermal Overload Motor Protection

To ensure maximum operational safety and equipment longevity, the motor is equipped with 

a thermal overload relay. This relay continuously monitors motor current and temperature, 

tripping the power supply if abnormal conditions arise—such as overloading, phase loss, 

or mechanical seizure. This proactive protection minimizes downtime and repair costs.

5. Two-Stage Filtration Architecture

The LYC-63B employs a highly effective two-stage filtration process. The suction line is fitted 

with a coarse strainer (crude filter) that captures large particulates and debris, protecting the

 gear pump from abrasive wear and extending its operational life. This is followed by a two-stage 

fine filtration section, where the primary and secondary fine filter elements work in tandem to

 rapidly achieve and maintain high oil cleanliness levels. This dual-stage design ensures both 

pump protection and superior final filtration efficiency.

6. Customizable Fine Filtration Precision

The fine filter housing accepts a wide range of interchangeable filter elements, allowing users to 

select the exact filtration rating required for their application—from 3μm for ultra-clean 

servo-valve systems to 40μm for general-purpose circulation. This flexibility means that 

a single machine can serve multiple roles across different equipment or processes, simply by 

swapping elements, offering outstanding return on investment.

7. Tool-Free Quick-Open Shell Design

Maintenance and filter changes are remarkably simple, thanks to the innovative quick-opening 

top cover. The shell is designed with a clamping or twist-lock mechanism that allows the cover 

to be opened rapidly without any tools, enabling operators to inspect or replace filter elements

 in minutes. This minimizes service downtime and encourages regular maintenance, ensuring 

consistent filtration performance.

8. Real-Time System Monitoring with Panel-Mounted Pressure Gauge

A large, easy-to-read pressure gauge is mounted on the front control panel, providing continuous, 

real-time indication of the system's operating pressure. This gauge serves a dual purpose: 

it verifies normal pump output and, more importantly, acts as a visual indicator of filter element 

contamination. As the element loads with captured particles, the differential pressure rises; 

a significant increase signals that the filter element requires replacement. This simple yet 

effective monitoring tool empowers operators to schedule maintenance proactively,

avoiding unexpected failures and ensuring that the oil remains at the desired cleanliness level.

Operational Benefits and Industrial Applications

The LYC-63B explosion-proof oil filter delivers measurable operational benefits: 

reduced component wear, extended oil life, lower disposal costs, and improved machine 

reliability. It is ideally suited for use in power generation, steel and aluminum rolling, 

mining equipment, offshore platforms, chemical processing, paper mills, and heavy-duty 

mobile machinery. Its explosion-proof certification makes it the preferred choice for applications

 involving flammable fluids or atmospheres, such as in refineries, fuel handling, and paint shops.

Furthermore, the unit is designed for easy integration into existing maintenance routines.

Its mobility allows it to be shared among multiple machines, while its bypass capability ensures 

that filtration can occur without shutting down primary production equipment. 

With its combination of rugged construction, flexible filtration precision, 

and user-centric maintenance features, the LYC-63B represents a best-in-class solution for 

achieving and maintaining ultra-clean hydraulic and lubrication fluids in the most demanding

 industrial settings.
