Product Overview
hydraulic filter cartridge renewal in power plants is normally driven by element part numbers rather than by housing replacement, and the PALL HC8314FKN26H is one of the return-line elements most frequently requested for turbine lube oil service. Our element is built as a direct interchange: the same end-cap geometry, the same sealing interface and the same nominal dimensions as the original, with HV grade fiberglass media in place of the OEM material. It is installed in the return-line housing of the turbine lubrication console, where it removes bearing wear debris and oxidation products from oil returning to the main reservoir.
Basic Technical Parameters
| Cross-reference | PALL HC8314 series element (HC8314*26H) |
| Media | HV grade fiberglass, multi-layer pleated |
| Micron rating | Per original part number (003 / 006 / 012 / 025 μm options) |
| Seal material | NBR standard; FKM on request |
| Working medium | Mineral turbine oil, hydraulic oil, phosphate ester / water-glycol with matching seals |
| Application | Turbine lube oil return line, hydraulic return line |
Power Plant Application Scenario
On a steam turbine unit, the lubrication console returns several hundred litres per minute to the main tank, and bearing wear particles produced during start-up collect in that return flow. The PALL replacement filter element sits in the return-line housing downstream of the bearing drains, so any debris released during a start-stop cycle is captured before it re-enters the supply header. Plant practice is to change elements after each major overhaul and to monitor differential pressure in between; because the housing stays in place, the work is limited to isolating the chamber, removing the cover and swapping the cartridge. Particle counts taken after the change are compared against the cleanliness target for the turbine oil, and the beta-ratio performance of the fiberglass media is what determines whether that target is met.
Product Advantages
Gradient multi-layer fiberglass construction puts coarser media upstream and finer media downstream, so the element holds a larger dirt load than a single-density pleat of the same area. The pleat pack is stabilised to resist flow fatigue, and end caps are bonded rather than merely crimped, which avoids bypass at the seal under pressure cycling. Dimensional control is held to the original interface so the element seats without force and without gaps at the O-ring groove. Each unit is checked for fabrication integrity before packing, and material compatibility is verified for the intended oil family.
Manufacturer & Factory Strength
Xinxiang Lifeierte Filter Corp., Ltd (Stock Code: 837936) has more than 15 years of experience producing interchangeable elements for PALL, HYDAC, MAHLE and PARKER housings, and publishes test results against ISO 2941, 2942, 2943, 3724 and 16889. Elements are supplied from a dedicated PALL replacement filter element line, so cross-reference verification and repeat ordering use one process. Where a plant is renewing the complete console rather than the element alone, the matching return line filter assembly is available from the same programme.
FAQ
Q1: Does the HC8314FKN26H element fit the original PALL housing without modification?
A1: Yes. End-cap geometry, sealing interface and nominal dimensions follow the original, so installation is a direct drop-in with no housing change.
Q2: What micron rating should be ordered?
A2: The rating follows the original part number; 003, 006, 012 and 025 μm options exist. Confirm against the OEM part list rather than assuming a grade.
Q3: Is fiberglass media acceptable for phosphate ester fluid?
A3: Media compatibility is generally acceptable, but the seal material must be matched to the fluid and compatibility should be confirmed at order stage.
Q4: When should the element be changed?
A4: On differential pressure reaching the alarm value, or at the overhaul interval set by the plant. Do not extend the interval purely on calendar time.
Q5: Can you supply other PALL series elements in the same order?
A5: Yes. The HC series covers many sizes; send the original part numbers and quantities for a cross-reference quotation.
