0500D010BN3HC 0160D020BH3HC Hydraulic Pressure Filter Element | Hydac Equivalent

The industrial-grade 0500D and 0160D High-Pressure Pipeline Hydraulic Filter Elements (including globally demanded replacement codes 0500D003BN3HC, 0500D005BN3HC, 0500D010BN3HC, 0500D020BN3HC, 0160D020BN3HC, and the high-strength 0160D020BH3HC), engineered by Chengyuan Hydraulic, are premium-tier fluid purification components designed for high-pressure lines, servo-proportional blocks, and closed-loop hydraulic motor circuits. Formulated with direct-fit geometries that provide 100% drop-in interchangeability with prominent global filtration catalogs (such as HYDAC Betamicron series), these elements insert seamlessly into pre-existing pipeline filter assemblies without custom enclosure alterations or spatial re-engineering.

Up to 80% of systemic failures in high-pressure oil circuits stem directly from solid particulate contamination. Positioned downstream of high-displacement pumps and upstream of sensitive valve banks, these pressure filters must endure severe transient fluid velocity rushes, high thermal shifts, and sudden structural impulses during hydraulic reversing cycles. Chengyuan’s replacement elements feature micro-toleranced machining on the zinc-plated end caps, precision outer multi-layer pleating, and high-durometer Fluorocarbon (Viton) sealing rings that strictly match the original manufacturer datasheet standards. This guarantees complete bypass exclusion and rigid seal longevity under peak system pressure.

The ultimate value of a high-pressure filter element relies on its ability to resist structural pleat collapse and maintain a high particle capture efficiency (Beta ratio) under extreme differential pressures ($\Delta p$). Any localized pleat bunching or media breach allows destructive contaminants to bypass the filter and scoring downstream components. To ensure reliable performance under these conditions, 100% of Chengyuan’s pressure elements undergo 100% rigorous dynamic simulation test bench and collapse pressure validation. Adhering to multi-pass ISO 16889 testing protocols, our batches are verified under high-viscosity cold-start loads and strict pressure limits (2.1 MPa for BN3HC and 21.0 MPa for BH3HC) to guarantee zero structural deflection over extended lifetimes.

Key Technical Advantages

• Multi-Layer Gradient Microglass Matrix Material: The main filtration layer utilizes premium imported composite glass microfibers featuring a void volume porosity exceeding 85%. Engineered with a tapered gradient matrix—where the pore sizing narrows progressively from the outer boundary to the inner core—it captures coarse contaminants on the surface while trapping fine silt deep within, boosting total dirt-holding capacity by over 1.5 times compared to single-layer or paper variants.

• High Particle Retention Stability ($\beta_x(c) \ge 1000$): Tested in accordance with international ISO 16889 multi-pass evaluation standards, this media delivers a Beta rating of 1000 at the designated micron level. This ensures that 99.9% of targeted particulate matter is captured on its initial pass. The fiber matrix resists shifting or media migration even under high fluid velocities or steep viscosity changes.

• High-Mesh Stainless Steel pleat-Support Underlay: To prevent pleat bunching and folding deflection caused by continuous hydraulic cycles, the microglass layer is reinforced on both sides by high-rigidity galvanized or stainless steel mesh. This provides a durable mechanical backing and clear flow channels, maximizing effective surface area and reducing initial differential pressure drop by over 20%.

• Thermosetting Structural Epoxy End Cap Adhesive Curing: The interface between the pleated media bundle and the metal end caps is sealed using a computer-controlled, two-part structural thermosetting epoxy. Cured under strict thermal parameters, the polymer achieves a strong chemical bond with the components. The resulting adhesive layer is dense, uniform, and free of air pockets, preventing fluid bypass even under prolonged $+120^{\circ}\text{C}$ oil exposures or high differential pressure loads.

Application Areas

The 0500D and 0160D series high-pressure elements are critical inline safeguards used to protect highly sensitive downstream control components:

• Heavy Duty Power Units & Servo Circuits: Positioned immediately downstream of high-pressure pumps to protect servo valves, proportional throttle systems, and electronic logic manifold blocks.

• Metallurgical Smelting & Rolling Mill Control Blocks: Serving as the main full-flow continuous filtration core within rolling mill AGC (Automatic Gauge Control) hydraulic loops.

• Severe Construction & Tunnelling Machinery: Return-line or pressure-feed filter cartridges for cutterhead drive motors on tunnel boring machines (TBM) and heavy drilling rigs.

Expert Maintenance Tips

• Never Substitute a High-Collapse BH3HC Element with a Standard BN3HC Variant in Non-Bypass Loops: BH3HC cores are specifically designed for non-bypass high-pressure filter housings where oil must never pass downstream unfiltered. If a standard BN3HC element is used instead, it can collapse and burst when clogged, causing catastrophic downstream contamination.

• Replace the Filter Element Immediately When the Differential Pressure Indicator Reaches $\Delta p = 0.5 \text{ MPa}$: Do not delay maintenance to extend component run-time. At this threshold, the core has accumulated significant debris, causing flow restriction to rise sharply. In systems with a standard bypass valve (often paired with BN3HC elements), exceeding 0.6 MPa will open the valve and allow unfiltered fluid to bypass the media entirely.

• Thoroughly Inspect and Lubricate the Viton O-Rings with Clean System Oil Before Installation: The tolerances within high-pressure filter heads are exceptionally tight. Sliding a dry O-ring into the housing can cause it to twist, nick, or shear against internal metal steps or thread edges. Applying a thin layer of clean hydraulic oil ensures smooth sealing alignment and prevents high-pressure cross-port weeping.
