Variable displacement pump DPVO

DPVO product family

The new nominal size 550 cm³

On the pulse of current affairs with new nominal sizes of open circuit pumps

The variable displacement axial piston pumps DPVO are of swash plate design and built for open circuit and high-pressure applications. They stand out through their large swivel angle as well as a high-pressure resistance. The pumps offer a 100-percent throughput capability. In order to keep pace with the ever-increasing demands for availability and durability, the DPVO product family has been extended to include the nominal size 550 cm³. This can also be used as a double pump 1100 cm³.

DPVO 550i – the newest member of the pump family

The new nominal size 550 cm³ was developed in close cooperation with customers for use under extreme working conditions. Thanks to its robust and reliable design, it is particularly suitable for mining and maritime applications, mechanical and plant engineering, special vehicle construction and tunnelling. Thanks to the impeller, a higher speed and thus a higher displacement becomes possible. With the new variable displacement pump the customer's requirements for very long working hours were achieved.
