Hydraulic Filter YWU-100X180J

Hydraulic Filter YWU-100X180J (Type: YWUX-100X180) – High-Flow Suction Line Element

The YWU-100X180J (Element Type: YWUX-100X180) is a heavy-duty, cleanable wire-mesh suction filter engineered specifically to safeguard high-displacement hydraulic pumps, steering gear hydraulic systems, mooring winches, and centralized hydraulic power units (HPUs).

This filter screens out primary particulate contaminants, weld slag, scale, seal degradation fragments, and suspended solids before hydraulic fluid enters positive displacement pumps (axial piston, vane, or gear configurations). Built with corrosion-resistant stainless steel wire mesh over a high-collapse perforated inner core, the YWUX-100X180 element provides minimal pressure drop across high-velocity flows, actively preventing suction line cavitation during cold starts and high-viscosity marine service conditions.

Features

1. Rigid Pleated SUS Mesh: High-grade stainless steel woven wire mesh delivers precise 180-micron coarse filtration without fiber migration or chemical breakdown under high hydrodynamic shear.
2. Ultra-Low Suction Resistance: Specially calibrated open-area ratio guarantees minimal entry head loss (Δp ≤ 0.01 MPa), protecting expensive hydraulic pumps against catastrophic suction cavitation and dry-run damage.
3. Pressure-Resistant Heavy Center Core: Perforated inner steel tube supports continuous radial suction loads and abrupt vacuum spikes caused by cold-start surges or valve shifting.
4. Washable & Reusable Media: Unlike micro-glass or cellulose filter elements, the SUS wire cloth can be chemically ultrasonically washed and back-flushed during scheduled vessel overhauls, reducing operational consumables costs.
5. Universal Tank/Line Porting: Standard threaded port design fits cleanly through inspection covers or tank top fittings for fast drop-in turnaround during dry-docking and critical port turnarounds.

Applications

• Marine anchor windlass and mooring winch electro-hydraulic power packs.
• Auxiliary engine lubrication pre-filtration and booster pump suction loops.
• Tank-mounted submerged suction lines for axial piston and vane pumps.
• Shipboard davits, cargo crane winches, and steering gear hydraulic reservoirs.
• Mobile heavy-equipment transmission and hydraulic drive suction lines.
• Metal recycling shears, stamping presses, and plant hydraulic flushing skids.

Frequently Asked Questions

What is the filtration rating of the YWU-100X180J hydraulic filter?

The YWU-100X180J operates at a nominal rating of 180 microns (µm), utilizing a stainless steel wire mesh design. This provides coarse straining to protect hydraulic pumps from mechanical particles while keeping hydraulic inlet flow resistance minimal.

What is the difference between YWU-100X180J and YWUX-100X180?

YWU-100X180J typically designates the complete filter assembly (housing, threaded head, and internal screen), whereas YWUX-100X180 refers specifically to the internal replacement filter element/cartridge used within that assembly.

Can the YWUX-100X180 stainless mesh element be cleaned and reused?

Yes. Because the filter medium is manufactured from high-grade woven stainless steel wire cloth, it can be cleaned using non-chlorinated hydrocarbon solvents, solvent degreasers, and low-frequency ultrasonic cleaning baths, followed by dry compressed air blowing from the inside out.

Where should the YWU-100X180J filter be installed in a hydraulic circuit?

This filter is engineered for suction-side service. It is installed either immersed directly inside the oil reservoir on the pump intake pipe or mounted in-line immediately preceding the primary hydraulic pump inlet.

What happens if the suction filter becomes clogged during operation?

If the filter element becomes fouled with debris, inlet flow to the pump drops sharply, creating a severe vacuum. This causes oil cavitation—where vapor bubbles form and violently implode against pump pistons, gears, or vanes—leading to noise, severe vibration, overheating, and mechanical pump failure. Ensure regular inspection of suction pressure gauges.
