Two-stage high/low pressure hydraulic pump 8.3 cm3/rev, 250 bar | HL series
Marzocchi Pompe
Very special double stage pumps with unloading valves. HL pumps are ideal for applications requiring a quick approach and/or return of the actuator at low loads (defined by the sum of the flows of the first and second stage) and slow motion of the actuator at high loads (defined by the first stage). Compared to traditional pumps, HL ones require a less powerful motor. HL pumps are available for groups 1, 1P, and 2. All displacement combinations for the two stages, flanges and shafts are available for a very flexible configuration of the pump.
