Product catalog summary
Overview: The Liebherr DPVO series axial piston pumps are designed for open circuits with a swashplate configuration. These pumps are suitable for high-pressure applications, offering nominal sizes from 108 to 215, with a nominal pressure of 5,802 psi (400 bar) and a maximum pressure of 6,527 psi (450 bar).
Specifications: The pumps feature a 22° swivel angle and 100% through-drive capability. They are compatible with various control types and can be combined with common controls. The pumps are available with or without an impeller, which enhances self-suction speed and displacement.
Technical Data: The displacement volume ranges from 6.57 to 13.22 inch³ (107.7 to 216.6 cm³), with maximum speeds varying from 2,000 to 2,600 rpm depending on the model. The drive power ranges from 202 hp (151 kW) to 503 hp (375 kW), and the drive torque ranges from 505 lbf·ft (685 Nm) to 1,016 lbf·ft (1,378 Nm).
Control Options: Available controls include electro-proportional regulation, pressure control, load sensing, and fan drive control. The pumps can be equipped with various mounting flanges and shaft ends, and they support through-drive for pumps of the same size.
Design and Configuration: The pumps are designed with a splined shaft profile and offer different connection diameters and fastening options. They are available with or without additional components such as gear pumps and sensors.
Applications: These pumps are suitable for a wide range of applications in mechanical, hydraulic, electric, and electronic drive and control technology. Liebherr provides comprehensive support from product development to customer service.

DPVO Short Description-1

Short description Axial piston pump DPVO --- The Liebherr axial piston pumps in the DPVO series are designed as swashplates for open circuits. These variable displacement pumps are available in nominal sizes ranging from 108 to 215. The nominal pressure of the units is 5,802 psi (400 bar) and the maximum pressure is 6,527 psi (450 bar) absolute. These pumps for open circuits with inverted piston design were specially developed for high pressure applications. They stand out with a 22° swivel angle and high pressure capacity, as well as 100 percent through-drive capability. They can be combined with all common controls. In nominal sizes 165 and 215, the variable displacement pump is also available with impeller. This achieves a higher self-suction speed and a higher displacement. Valid for: DPVO 108 involute gear hub profile DPVO 140 involute gear hub profile DPVO 165 / DPVO 165i DPVO 215 / DPVO 215i Features: D series Open circuit Control types: Various control types can be selected Pressure range: Nominal pressure pN = 5,802 psi (400 bar) Maximum pressure pmax = 6,527 psi (450 bar)
