Pall HC7500SDS8Z Replacement Filter Element — Cross-Reference & Specifications
Pall HC7500SDS8Z Replacement Filter Element — Cross-Reference & Specifications
Hydrafil Part Number: BF-PAL-923913-L8-12MV | Ships same day from Detroit, MI | OEM-equivalent performance
The Pall HC7500SDS8Z combines three demanding specifications into one element: 12-micron filtration, Viton (Fluorocarbon) seals, and the long 10.9 in body for maximum media surface area. This configuration is engineered for large, high-flow hydraulic systems that also operate on phosphate ester fluids, synthetic esters, or at sustained elevated temperatures — the kind of environment found in steel mill hydraulics, heavy-press circuits, and marine applications where chemical resistance can’t be sacrificed for flow capacity. If your system specifies an HC7500 long-body housing and runs any fluid other than conventional mineral oil, the SDS8Z’s Viton seal is not optional; it’s the correct OEM spec.
Dimensional Specifications
The long-body 10.9 in length provides substantially greater media area than the short-body SDS4Z — verify your housing model before ordering, as L4 and L8 housings are not interchangeable.
| Specification | Value |
|---|---|
| Outer Diameter (Top) | 5.06 in |
| Outer Diameter (Bottom) | 5.06 in |
| Element Length | 10.9 in |
| Thread Size | 1.5 - 16 |
| Collapse Rating | 100 psid |
Media & Construction
The BF-PAL-923913-L8-12MV delivers OEM-grade construction throughout, with Viton sealing for compatibility with aggressive hydraulic fluids.
- Filtration Media: Microglass Fiber Media — the extended L8 body provides greater media area, reducing initial ΔP at high flow rates and extending element service life before reaching bypass pressure
- Seal Material: Viton (Fluorocarbon) — resists swelling and degradation in phosphate ester fluids (Fyrquel, Skydrol), synthetic esters, and polyol ester-based fire-resistant fluids; rated for sustained service temperatures up to 400°F where Buna-N would fail
- End Caps: Corrosion Resistant Steel — essential in chemical-aggressive fluid environments where standard steel end caps would corrode prematurely
- Center Tube: Corrosion Resistant Steel — provides structural stability under the 100 psid collapse rating, critical in high-flow circuits with rapid pressure cycling
Filtration Performance Rating
The 12µm rating positions this element between general-purpose 25µm return-line filtration and high-precision 6µm servo-valve filtration — ideal for proportional valve circuits, vane pump pressure lines, and actuator circuits where ISO 4406 cleanliness targets in the 17/15/12 to 16/14/11 range are required.
The Viton-sealed long-body configuration is the OEM specification for high-flow phosphate ester systems in heavy industry — steel processing, die casting, and marine hydraulics — where both chemical compatibility and 12µm particle removal are mandatory, not optional.
| Rating | Value |
|---|---|
| Beta Ratio (Bx) | 200 |
| Beta Ratio Bx[c] | 1000 |
ISO Standards Compliance
Manufactured and tested to the full ISO hydraulic filter standard suite, matching the Pall OEM element specification.
| ISO Standard | What It Tests |
|---|---|
| ISO 2941 | Collapse & burst resistance |
| ISO 2942 | Fabrication integrity & bypass valve function |
| ISO 2943 | Material compatibility with hydraulic fluids |
| ISO 3724 | Flow fatigue characteristics |
| ISO 3968 | Pressure drop vs. flow rate characteristics |
| ISO 16889 | Multi-pass performance (Beta ratio methodology) |
About the Pall HC7500SDS8Z
The HC7500SDS8Z is the high-capacity, chemically resistant specification in Pall’s HC7500 / 50-AT element family — selected for large industrial hydraulic power units in steel mills, heavy press installations, offshore marine systems, and die casting facilities where fire-resistant phosphate ester fluids are mandated by safety codes and flow rates demand the full media area of the long-body housing. The 12µm Viton combination delivers reliable intermediate filtration performance in the most chemically aggressive hydraulic service environments.
