    Donaldson HPK04 In-Line Cartridge Filters


    Donaldson HPK04 filters are high pressure in-line cartridge filters, constructed of ductile iron and steel for strength and durability.

    Machined bypass valves are case-hardened at critical points to provide maximum strength and reliability. A reverse flow bypass valve allows bi-directional flow through the filter head, and filter change out is simplified with standard housing drain plug.

    HPK04 filters are suitable for: hydrostatic transmission and servo valve circuits.

    Maximum working pressures go to 413.8 bar (6000 psi) and rated static burst to 1173 bar (17000 psi). Their flow range is to 454 litres/minute and operating temperature range is -27°C to 121°C (-20°F to 250°F).

    Filter cartridges for HPK04 contain Synteq™, Donaldson’s exclusive synthetic fibre media formulated specially for liquid filtration. Upgraded Donaldson high-performance DT filters are also offered for superior performance.

    Bypass options include 4.1 bar (60 psi) bypass, 6.2 bar (90 psi) bypass with reverse-flow check valve, or no bypass.
