Danfoss Hydraulic Portfolio: Pumps, Motors, HPU, and Systems

Danfoss built its hydraulic product range around a specific proposition: that the greatest efficiency gains come not from improving individual components but from designing those components to work together. The breadth of their hydraulic portfolio — pumps, motors, hydraulic power units, system controls, and now digital displacement technology — is what makes that proposition actionable.

Hydraulic Pumps

The Danfoss hydraulic pump range spans fixed displacement gear units for simple circuits through variable displacement axial piston designs with advanced load-sensing controls, up to the digital displacement pump for applications demanding the highest available efficiency at partial loads. Each series is designed with defined control interface options that integrate with Danfoss motor drives and system electronics without requiring custom adaptation.

Hydraulic Motors

Danfoss motors — orbital, bent-axis piston, and axial piston designs — cover the output end of the same hydraulic circuits their pumps serve. An industrial hydraulic motor from the Danfoss range is matched in control interface and fluid specification to the corresponding pump, reducing the system integration work that independently sourced pump-motor pairs require. The speed and torque controllability available through Danfoss servo valve integration is comparable to dedicated servo electric drives in many positioning applications.

Hydraulic Power Units

Danfoss hydraulic power unit packages — HPUs — integrate pump, motor, reservoir, and control electronics in a tested and commissioned assembly. This approach shifts engineering work from the end customer or system integrator to Danfoss, where the component interactions are fully understood. For industrial machinery builders who need a hydraulic drive without deep hydraulic expertise in-house, a Danfoss HPU significantly reduces development risk and time.

System-Level Approach

The consistent design language across Danfoss pumps, motors, and controls means that system-level optimization — coordinating pump displacement with motor speed and load feedback — is achievable without the custom control software that mixed-supplier systems require. Energy efficiency and low emission targets that are difficult to meet with individual component selection become realistic when the pump, motor, and drive are all operating on a shared control architecture.
