20mm SS316L Perforated Hydraulic Suction Strainer

20mm SS316L Perforated Hydraulic Suction Strainer

From Toptitech, this filter element is manufactured from 316L stainless steel, offering corrosion resistance and oxidation stability for use in water-based fluids, oils and mild industrial environments. The 2mm holes are precision-punched with uniform spacing and clean edges, ensuring consistent filtration. Formed by stamping without welding, the structure maintains full material integrity.

With 1mm wall thickness, this component provides structural strength to withstand pressure fluctuations and fluid impact in hydraulic systems. Its open-ended design allows straight-through flow and flexible installation in various piping layouts. Smooth surfaces and clear internal passages minimize pressure drop and maintain flow efficiency. This filter element suits applications including hydraulic suction strainers, pump inlet protection and pipeline coarse filtration where reliable performance is required.

Product Features
Material Purity
Manufactured from high-purity 316L stainless steel, this filter element ensures long-term corrosion resistance and service life, maintaining stable chemical inertness in hydraulic return line applications.

Integral Formed Structure
Formed through continuous stamping in a single operation, the design eliminates stress concentration points associated with welded joints, preserving structural integrity under high-frequency vibration at hydraulic suction ports.

Negative Pressure Resistance
The uniformly thick wall construction withstands瞬时 negative pressure surges in suction lines, maintaining consistent cylindrical geometry without collapse or deformation to ensure uninterrupted pump suction.

Optimized Flow Cross-Section
Hole arrangement is engineered based on fluid dynamics principles, maximizing flow capacity within the limited cylindrical surface area to accommodate high suction flow demands during hydraulic system startup.

Hole Edge Quality
Punched edges undergo specialized finishing treatment, eliminating burrs that could generate secondary contaminants, protecting hydraulic pumps and downstream precision components from abrasive wear.

Surface Cleanliness Treatment
Each component undergoes professional degreasing and cleaning prior to shipment, removing processing residues for direct installation into hydraulic systems without oil contamination, reducing commissioning time.

Product Applications
Hydraulic Tank Suction Protection
Installed at the suction port inside hydraulic reservoirs, this element intercepts large particulate contaminants before fluid enters the suction line, providing the primary barrier for hydraulic pump protection.

Pre-Pump Inline Filtration
Positioned in the hydraulic pump inlet line, it removes suspended particles prior to fluid entering the pump chamber, reducing internal wear and extending pump service life.

Return Line End Filtration
Placed at the terminal end of hydraulic return lines, it captures particulate contaminants generated during system circulation before fluid re-enters the tank, maintaining internal fluid cleanliness.

Construction Machinery Hydraulic Systems
Engineered for excavators, loaders, and similar heavy equipment, it delivers reliable pump protection under demanding conditions, addressing contamination risks inherent in high-dust environments.

Industrial Lubrication Systems
Installed at suction ports of oil lubrication units, it filters solid impurities from lubricating oil, ensuring clean fluid reaches lubrication points to protect bearings and friction surfaces.

Flush System Temporary Filtration
Deployed as a temporary suction strainer during hydraulic system flushing, it captures dislodged contaminants, accelerating the process of achieving target system cleanliness levels.
