Hydraulic Pumps

A hydraulic pump is a mechanical device that converts mechanical power into hydraulic energy. It generates flow with enough power to overcome pressure induced by the load.

When a hydraulic pump operates, it performs two functions. First, its mechanical action creates a vacuum at the pump inlet which allows atmospheric pressure to force liquid from the reservoir into the inlet line to the pump. Second, its mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system.

A pump produces liquid movement or flow: it does not generate pressure. It produces the flow necessary for the development of pressure which is a function of resistance to fluid flow in the system. For example, the pressure of the fluid at the pump outlet is zero for a pump not connected to a system (load). Further, for a pump delivering into a system, the pressure will rise only to the level necessary to overcome the resistance of the load.

Axial Piston pumps

Axial piston pumps in swash plate and bent axis design are intended for the medium and high pressure range. Numerous variations in the designs, performance ranges, and adjustment options offer ideal solutions for mobile and stationary applications.

Maximise performance, efficiency, and profit

Perfect fit for your applications: The H1P can be used in overall hydraulic systems. Also, it fits hundreds of applications in an easily integrated package

Efficiency: The integral electro-hydraulic servo system is controlling the rate and direction of the hydraulic flow. This guarantees lowest servo pressure and excellent high-power density. Operating at maximised efficiency, the H1P will lower your total costs of ownership

Optimized profile and design: The integrated Gerotor charge pump design including pressure balanced port plates reduces volumetric losses to a possible minimum

Compactness: A lower total number of parts such as one single swash plate, and no T-bar. These make operating your machine as simple as possible, still providing best quality at highest standards

Clean side and flexibility: The lightweight, compact H1P is designed with one true clean side. In addition, no operating ports to connect resulting in a flexible placement of components

Precise control and reliability: Lower total control losses and better resolution due to high current solenoid. These lead to an optimized, reliable, overall control performance, allowing for predictable and safe machine operation

Variety of control options: Automotive Control (AC), Electrical Displacement Control (EDC), Fan Drive Control (FDC), Forward-Neutral-Reserve Control (FNR), Mechanical Displacement Control (MDC), Non-Feedback Proportional Electric Control (NFPE)

The H1P solution model: Tools, documentation, modeling, software, and expert knowledge. These are based on Danfoss’ decades of experience available when need mean you get quicker access

Wide range of displacements: Offering a range of pumps with 45-280 cm² per round. The H1P is a modular pump flexible enough to fit all kinds of applications
