What The HFPK Series High Flow Parker Equivalent Does In Your Line
HFPK is a 6 inch large diameter high flow cartridge with a pleated polypropylene media pack, an inner core and an injection moulded outer cage. It runs outside-in, so dirt is captured on the outside of the pleat pack and stays there during change-out. One HFPK element replaces a bank of 2.5 inch cartridges, which is why plants fit it when the existing filter skid has run out of housing space. It is dimensionally equivalent to the installed Parker Filtraman HFPK series and drops into those housings without adapters.

Why Buyers Pick This Element
- One 6 inch element does the work of a bank of 2.5 inch cartridges and frees skid footprint
- Large filtration area and high flow rate reduce pressure drop and extend change-out intervals
- Outside-in flow path keeps captured solids on the cartridge when an operator lifts it out
- Built-in handle enables fast and easy change-out without tools
- Injection moulded outer cage takes the differential pressure without pleat collapse
- Dimensional equivalent to the installed Parker Filtraman HFPK series so no piping or housing change is needed
Buyers Who Specify This Cartridge
- Water treatment plant engineers replacing OEM high flow cartridges on an existing skid
- RO system integrators specifying prefiltration for new desalination or process water trains
- Beverage and food plant maintenance teams standardising on one cartridge across lines
- Filtration distributors who need an equivalent series to quote against OEM part numbers
What It Fixes On The Line
- Cartridge change-out on a large skid takes hours because there are too many small elements
- OEM high flow cartridges carry long lead times and high unit cost per replacement cycle
- Filter housings are full and there is no floor space to add another vessel for more flow
- Pleat packs collapse under differential pressure and shed captured solids back into the line
- Solids fall off the element during change-out and contaminate downstream filtrate
Construction Detail
- Vertical pleated construction that maximises effective filtration area per element
- Single piece full length media pack with no joints along the cartridge
- Inner core plus injection moulded outer cage for differential pressure strength
- Outside-in flow path for contaminant retention during change-out
- Built-in handle for fast and easy change-out without tools
- Round double O-ring and claw single O-ring adapters to match installed housings
- Absolute micron ratings from 1 to 100 micron across the same body
Materials Of Construction
- Polypropylene filtration media, thermally bonded without adhesives or surfactants
- Polypropylene inner core and injection moulded outer cage
- EPDM O-rings for general water and hot water service
- Viton O-rings for aggressive chemical and higher temperature duty
- Buna O-rings for hydrocarbon and general industrial water
- Silicone O-rings where a low extractable elastomer is preferred

How This Cartridge Is Built
Media Preparation
Media extrusion and pleating to a fixed pleat pitch
Pack Forming
Vertical pleat pack forming to full cartridge length in one piece
Hardware Assembly
Core insertion and injection moulded cage assembly
End Cap Bonding
Thermal end cap bonding without adhesive
Configuration
O-ring and adapter fitting to the ordered configuration
Inspection And Packing
Flush, drain and individual packing
Checks Before It Ships
- Dimensional check of outer diameter, length and adapter against the ordered code
- Pleat pack inspection for collapse, gaps and end cap bond integrity
- Differential pressure check against the 3.5 bar at 21 C rating
- O-ring compound and seating verification before packing
What We Can Change For You
- Length combinations from 40 inch to 60 inch to match the installed housing
- Micron rating selected from 1 to 100 micron for the duty
- O-ring compound chosen from EPDM, Viton, Buna or Silicone
- Standard adapter or extended adapter to match the existing seat
- Private label printing and carton marking for distributors
How It Compares With The Alternatives
| 2.5 inch pleated cartridges | HFPK cuts element count and change-out labour, but the initial cartridge cost per piece is higher |
|---|---|
| HFPK series with extended adapter | Same 6 inch envelope; HFPK with standard adapter fits most housings, extended adapter for deeper seat or longer seal |
| Bag filters | HFPK holds a tighter absolute rating and does not bypass at the seal, but a bag is cheaper for coarse duty |
| OEM branded high flow cartridges | Same dimensions and fit at a lower landed cost and shorter lead time, without the OEM warranty documentation |
Installing And Running This Cartridge
- Confirm housing bore, seat type and cartridge length before ordering; the adapter code must match
- Start clean differential pressure logging from day one so change-out is data driven
- Change out at 2.4 bar differential rather than waiting for the 3.5 bar maximum
- Do not exceed 80 C; select Viton O-rings if the duty runs warm or carries solvents
- Flush the housing before fitting a new element so settled solids do not load it immediately
- Lift the element vertically and keep it upright so captured solids stay on the pleat pack
