The pumps with open circuit and inverse piston technology are design especially for high pressure applications and impress with their large swing angle as well as a high resistance to pressure. They offer a through-drive of 100 percent and can be combined with all conventional controllers.
Hydraulic component - Axial piston pump
Circulation - open
Adjustability - variable
Nominal sizes - 108 / 140 / 165 / 215 / 215 impeller
Areas of application - Machinery and plant construction
The Liebherr axial piston pump DPVO series is developed for the open circuit in swash plate design.
These variable displacement pumps are available in nominal sizes ranging from 108 to 215. The nominal pressure of the units is 400 bar and the maximum pressure is 450 bar absolute.
The open circuit pumps with inverted piston design were especially developed for high pressure applications.
They impress with a 22° swivel angle and high compressive strength as well as a 100 percent through-drive capability.
The DPVO series is available with a variety of hydraulic and
electric controls. In nominal size 215, the variable displacement pump is also available with impeller. This achieves a higher selfsuction
speed and a higher displacement.
