Pumps for applications that require a fast approach and/or return of the actuator at low loads and slow motion of the actuator at high loads. In particular, these models offer the advantage of requiring lower power of the motor.
Specially designed for applications such as:
waste compactors
log splitters
clamp mechanisms
crimping machines
metal forming machines and so on
The Marzocchi 1HL, 1PHL and 2HL High/Low hydraulic gear pumps are special double-stage pumps with special integrated valves.
