Hydraulic Filter

Petronash hydraulic filters are designed to remove:

• dirt and dust particles
• micro particles (fine contamination)
• wear debris from pumps and valves
• impurities formed due to oil degradation
• foreign particles introduced during maintenance or oil filling

This prevents failure in sensitive hydraulic components.

If contamination remains in hydraulic oil, it can lead to:

• pump wear and damage
• control valve malfunction
• leakage and seal failure
• poor actuator performance
• frequent system breakdowns
• increased maintenance and downtime

Clean oil directly means stable system performance and lower operating cost.

Hydraulic filters are used in:

• hydraulic power packs (HPU)
• oil & gas hydraulic control systems
• wellhead control panels (WHCP)
• industrial presses and machines
• lubrication oil systems
• offshore hydraulic systems
• automation and process control hydraulic circuits

Essentially, wherever hydraulic oil is used, filtration is critical.

Petronash hydraulic filters support filtration levels:
3µm, 5µm, 10µm, and 20µm

Also, filter elements are available down to:
filter fineness of 3 microns

This makes them ideal for both general filtration and precision protection.

Filtration level depends on system sensitivity:

• 3µm: for high precision hydraulic systems & critical components
• 5µm: excellent for most hydraulic circuits
• 10µm: general filtration for normal-duty systems
• 20µm: pre-filtration or low sensitivity applications

If you're unsure, Petronash can help recommend the best micron rating based on your pump type and operating conditions.

Petronash hydraulic filters are designed for high-pressure service:
Working pressure: 150 / 450 / 700 Bar(g)
and suitable for working pressure up to:
700 Bar(g)

This makes them suitable for demanding industrial and oil & gas hydraulic applications.

Petronash hydraulic filters are suitable for:

• petroleum-based fluids
• mineral oils
• hydraulic fluids
• lubrication oils

They are designed for compatibility with hydraulic fluids as per:
ISO 2943

This ensures reliable sealing and long-term chemical resistance.

Petronash hydraulic filters support:
Working temperature: -10°C to 100°C

This covers most industrial operating environments including onshore and offshore installations.

A clogging indicator shows the level of filter element blockage due to accumulated contaminants. Petronash hydraulic filters can be provided with:
Visual clogging indicator (optional)

This helps operators know when to replace the element before pressure drop increases and affects performance.

DP setting refers to the differential pressure level at which the clogging indicator triggers.
Petronash standard clogging indicator DP setting:
5.0 Bar (standard)
Other DP settings can be provided on request based on project requirement.

This ensures timely filter element replacement and system protection.

Petronash hydraulic filters are built for durability and corrosion resistance:

Filter Head Material

• SS316L / Duplex SS / others

Filter Bowl Material

• SS316L / Duplex SS / others

O-ring / Seal

• FKM (Viton) / PTFE

These materials ensure strong compatibility with hydraulic fluids and long service life even in harsh environments.

Petronash hydraulic filters are trusted because they offer:

• high pressure capability up to 700 bar
• filter fineness up to 3 microns
• ISO 2943 hydraulic fluid compatibility
• optional clogging indicator for preventive maintenance
• robust construction with SS316L / Duplex materials

They are built for high reliability in critical hydraulic systems.

Yes. Petronash can customize hydraulic filters based on:

• connection size and porting requirements
• pressure rating (150/450/700 bar)
• filter fineness (3µm to 20µm)
• material selection (SS316L, Duplex, etc.)
• DP clogging indicator setting as per client standard

This helps ensure perfect integration into your hydraulic package.

Absolutely. Petronash can supply hydraulic filters:

• as standalone units, or
• integrated into complete packages such as HPUs, WHCPs, skids, and hydraulic control panels

This ensures correct sizing and performance matching to the overall system.
