ZX-63*80 Hydraulic Oil filter element

Product Overview

The ZX-63×80 filter element is a high-performance filtration component engineered specifically for hydraulic 

systems requiring reliable particulate contaminant removal. Designed as a direct replacement element for 

a wide range of hydraulic filtration assemblies, this product plays a critical role in maintaining fluid cleanliness, 

protecting sensitive hydraulic components, and extending the operational life of entire hydraulic circuits.

 With its robust construction, versatile material compatibility, and exceptional contamination-holding capacity, 

the ZX-63×80 has become a trusted choice across multiple heavy industries.

Sources of Contamination in Hydraulic Systems

Understanding the contamination sources that the ZX-63×80 addresses is essential to appreciating its value. 

Particulate impurities in hydraulic systems originate from multiple pathways:

Internal Generation: Normal mechanical wear of pumps, valves, cylinders, and motors continuously produces fine 

metal particles and abrasion debris. Even under ideal operating conditions, component interfaces generate microscopic 

wear particles that, if left unfiltered, accelerate further wear through abrasive action.

Ingressed Contaminants: During tank breathing, atmospheric air drawn into the reservoir carries airborne dust, dirt, 

and moisture. In industrial environments, ambient particle concentrations can be significant, and without effective filtration, 

these contaminants enter the hydraulic fluid and circulate through the system.

Maintenance Introduced: During fluid top-ups, component replacements, or system repairs, external contaminants can

 be inadvertently introduced unless strict cleanliness protocols are followed.

The ZX-63×80 filter element is specifically designed to capture these contaminants efficiently, preventing them from

 reaching critical system components.

Advanced Construction and Material Advantages

The ZX-63×80 is manufactured using premium-grade metal mesh media, configured in a pleated design that significantly

 increases the effective filtration area within a compact envelope. This pleated geometry delivers several performance 

benefits:

High Contamination-Holding Capacity: The expanded surface area allows the element to retain a substantial volume of 

particulate matter before reaching its pressure-drop limit, extending service intervals and reducing maintenance frequency.

Corrosion Resistance: The metal mesh construction resists degradation from moisture, water-glycol mixtures,

 and phosphate ester fluids, ensuring long-term reliability even in challenging operating environments.

Thermal Stability: The element maintains its structural integrity across a wide temperature range, performing consistently 

in both low-temperature start-up conditions and high-temperature continuous operation.

Pressure Durability: Engineered to withstand nominal system pressures of 1.6 MPa, the element resists collapse or deformation 

under transient pressure spikes, maintaining filtration efficiency throughout its service life.

Filtration Performance Characteristics

The ZX-63×80 employs an adsorption-type surface filtration mechanism, effectively capturing particles across the entire 

spectrum of 2–200 μm in size. This uniform filtration performance ensures that both fine silt-sized contaminants and larger 

wear debris are removed, providing comprehensive protection for pumps, servo-valves, proportional valves, and actuators.

Key performance attributes include:

· Uniform porosity across the entire filter medium, ensuring consistent filtration accuracy

· High flow capacity per unit area, minimizing pressure drop and energy consumption

· Excellent resistance to thermal and mechanical stress

· Cleanable and reusable design, offering economical long-term operation

Application Fields

The ZX-63×80 filter element is deployed across a broad spectrum of industries where hydraulic system reliability is 

non-negotiable:

Metallurgical Industry: Used in rolling mills, continuous casting machines, and various lubrication systems to protect 

hydraulic actuators and bearings from abrasive wear.

Petrochemical Sector: Applied in oil refining and chemical production for product and intermediate separation,

 liquid purification, and particle removal from well water and natural gas streams. Also utilized in manufacturing processes

 for tape, CDs, and photographic films.

Textile Manufacturing: Employs in polyester melt purification during drawing processes, air compressor protection filtration, 

and compressed air oil/water removal.

Electronics and Pharmaceutical: Critical in reverse osmosis water treatment, deionized water filtration, washing liquid

 pretreatment, and glucose solution clarification.

Thermal and Nuclear Power: Used in gas turbine and boiler lubrication systems, speed control circuits, bypass control oil 

purification, and feedwater pump/fan dust removal systems.

Product Differentiators

The ZX-63×80 stands apart from conventional filter elements due to its:

· Reusability after proper cleaning, reducing lifecycle costs

· Compatibility with multiple hydraulic fluid types, reducing inventory complexity

· Reliable performance in both low-temperature and high-temperature extremes

· Interchangeable design compatible with standard filter housings

Frequently Asked Questions

Q1: What is the filtration accuracy of the ZX-63×80, and is it suitable for servo-valve protection?

The ZX-63×80 offers a filtration accuracy of 80 μm. While this provides excellent protection for general hydraulic components, 

servo-valves typically require finer filtration (3–10 μm). For servo-valve applications, we recommend using a finer-grade filter

 element in series upstream of sensitive components.

Q2: Can the ZX-63×80 be cleaned and reused?

Yes, the metal mesh construction allows for cleaning and reuse. The element can be backwashed or ultrasonically cleaned

 using appropriate solvents. However, we recommend replacing the element after 3–5 cleaning cycles, as the metal mesh

 may experience fatigue over repeated cleaning operations. Always inspect the element for damage before reuse.

Q3: What is the difference between nitrile rubber (NBR) and fluoro rubber (FKM) seals, and which should I choose?

Nitrile rubber seals are suitable for mineral oils and general hydraulic fluids, offering good cost-effectiveness. Fluoro rubber

 seals provide superior chemical resistance, particularly for phosphate ester hydraulic fluids and higher-temperature 

applications. Select FKM seals if your fluid type or operating temperature exceeds 80°C.

Q4: How do I know when the ZX-63×80 filter element needs replacement?

The primary indicator is the pressure differential across the filter housing. When the differential pressure reaches the 

manufacturer's specified change-out value (typically 0.2–0.3 MPa above clean-element pressure drop), the element should 

be cleaned or replaced. Visual inspection for visible debris accumulation is also recommended during routine maintenance.

Q5: Is the ZX-63×80 compatible with water-glycol hydraulic fluids?

Yes, the ZX-63×80 is fully compatible with water-glycol hydraulic fluids. The metal mesh material and NBR seals are resistant

 to

 water-glycol mixtures, ensuring reliable performance and preventing seal degradation.

Q6: What is the maximum operating temperature for this filter element?

The ZX-63×80 operates effectively between -20°C and +120°C, depending on the seal material used. FKM seals offer better

 high-temperature performance than NBR. Always refer to your system's specific temperature range and select the 

appropriate 

seal option.

Q7: How does the pleated design benefit filtration performance?

The pleated configuration increases the effective filtration surface area by 3 to 5 times compared to a non-pleated element 

of the same size. This results in higher dirt-holding capacity, lower initial pressure drop, and extended service life—all critical 

factors for cost-effective hydraulic system operation.

Q8: Can the ZX-63×80 be used in systems with reverse flow?

The ZX-63×80 is designed for unidirectional flow. Reverse flow may damage the pleated structure or dislodge captured 

contaminants. If your system requires bidirectional filtration, please consult our engineering team for alternative solutions.

Q9: What maintenance practices are recommended to maximize element life?

To maximize the service life of the ZX-63×80, we recommend: maintaining system fluid at recommended viscosity levels, 

replacing fluid according to manufacturer schedules, installing a coarse pre-filter upstream to remove large debris, 

and monitoring differential pressure regularly to schedule cleaning before the element becomes fully saturated.
