Danfoss Series 90 Axial Piston Pump are developed in three sizes available (55, 75, and 100cc), used in various mobile machineries within construction, agriculture and material handling. Danfoss Series 90 pump is designed in high-Power Closed-Circuit displacements. These pumps are tried and true reputation, with millions of units produced over the span of more than three decades.

These pumps have perennial powerhouse that provide flexibility built right in, PLUS+1 Compliance, and is easy to convert or install. Danfoss series 90 is known for higher performance. low noise level and high power density. This pumps are available in minimum pressure 450 bar and maximum pressure 480 bar, also use the parallel axial piston/slipper design in conjunction with a fixed or tiltable swashplate. They can intake/discharge fluid through either port; they are bidirectional.

In order to supply cooling and system replenishing oil flow as well as control fluid flow, Series 90 pumps come with an integrated charge pump. In order to accommodate supplementary hydraulic pumps for usage in complementary hydraulic systems, they also have a variety of auxiliary mounting pads. There is a full range of control choices to accommodate different control systems.

Characteristics

Ease of integration with a small and clean footprint
Modular architecture that’s easy to convert and PLUS+1 compliant, give you fast tuning and easy parameter settings
Three displacements available so you can pick the right size for your machine
Long-lasting product life and global service available
