Donaldson HMK05 HMK25 Spin-On Filters
Donaldson HMK05 (single) and HMK25 (dual head) series DURAMAX® spin-on filters feature a heavy-duty steel body and die-cast top plate for added strength. The HMK25 double filter head means twice the flow capability, with two filters to hold more contaminant.
They are suitable for high flow applications including: case drains, cooling circuits, fluid conditioning systems, fuel transfer, hydrostatic charge pumps, lube oil systems, power transmissions, return lines and side loop systems.
A special head-to-canister O-Ring seal prevents leakage. Nitrile seals are standard; fluorocarbon seals are available on some models.
Maximum working pressures go to 24.2 bar (350 psi) and rated static burst to 55.2 bar (800 psi). The HMK05 has a flow range to 189 litres / minute, and the HMK25 to 379 litres / minute. Operating temperature range is:
- -29°C to 121°C (-20°F to 250°F) for synthetic;
- -29°C to 107°C (-20°F to 225°F) for cellulose;
- -29°C to 121°C (-20°F to 250°F) for wire mesh.
Standard bypass ratings are: 3.5 bar (50 psi), 1.73 bar (25 psi) or no bypass.
