Medium Pressure

HNK DURAMAX® spin-on hydraulic filter is the newest addition to Donaldson’s family of medium pressure filters. The HNK adds a proprietary fit to help you retain the replacement element business. DURAMAX is well-known as the highest rated spin-on style filters available. They are most often used in return-line positions. As spin-ons, they are particularly well-suited for duplex circuits. Available with Donaldson Synteq® and cellulose media. DURAMAX working pressures range from 350 psi up to 1000 psi; static pressures from 800 psi up to 2000 psi.

	W061 In-Line Hydraulic Filter Working Pressures to 600 psi / 41 bar Typical Burst Pressure to 1500 psi max / 103 bar Flow Range to 100 gpm / 379 lpm W061 specs
	HNK Duramax® Working Pressure: 500 psi / 3450 kPa / 34.5 bar Static Pressure: 1000 psi / 6895 kPa / 69 bar Flow Range: 0-50 gpm / 0-189 lpm HNK Duramax offers improved performance including higher burst, greater fatigue strength and longer filter life compared to standard spin-ons. It also provides a proprietary fit to help you keep the replacement business HNK specs
	HMK03 Duramax® Working Pressure: 1000 psi / 6895 kPa / 69 bar Static Pressure: 2000 psi / 13790 kPa / 138 bar Flow Range: 0-25 gpm / 0-95 l/min HMK03 offers TWICE the pressure capability of competitive filters, yet is physically smaller than traditional housing/cartridge filter assemblies HMK03 specs
	HMK04 (single head) & HMK24 (dual head) Duramax® Working Pressure: 500 psi/3450 kPa/34.5 bar Static Pressure: 1000 psi/6900 kPa/69 bar HMK04 Flow Range: 0-35 gpm / 0-130 l/min HMK24 Flow Range: 0-60 gpm / 0-230 l/min HMK04/24 Duramax models offer high flow capacities, heavy-duty design, and a very wide choice of replacement filters. HMK04/HMK24 specs
	HMK05 (single head) & HMK25 (dual head) Duramax® -- High Flow Static Pressure: 800 psi/5520 kPa/55.2 bar Working Pressure: 350 psi/2413 kPa/24.1 bar HMK05 Flow Range: 0-50 gpm / 0-189.3 l/min HMK25 Flow Range: 0-100 gpm, 0-378.5 l/min Full-range performance with Synteq® filter media for high-flow applications, with the ease and convenience of a spin-on! The double element head means double flow capability, with two filters to hold more contaminant! HMK05/HMK25 specs
