Danfoss DDP Digital Displacement Pump

Description

Danfoss DDP Digital Displacement Pump

Danfoss DDP Digital Displacement Pump is Danfoss’ electronically controlled Digital Displacement® pump for use in Dextreme excavator hydraulic systems. Its digital controller activates individual pistons in response to system demand, distinguishing the technology from a conventional swash-plate pump.

Manufacturer family: DDP Digital Displacement® pump (confirm full type code and system configuration)

Family-level product information: The specifications below describe the Danfoss family or product range, where applicable. They do not identify a single configured unit. Variants within a series can differ in displacement, pressure rating, control, shaft, mounting, ports, rotation and optional equipment; the complete type code is needed to check the requested configuration.

DDP Digital Displacement Pump for hydraulic equipment

This listing covers the Danfoss DDP Digital Displacement Pump. The family uses electronically controlled Digital Displacement® pump technology and is listed for excavator hydraulic systems using Danfoss Dextreme digital pump control. The range can include multiple sizes and configurations, so the complete type code and the machine’s requirements are needed to determine whether a specific unit suits the application.

Technical specifications

Use the values in this table as a first technical reference. Where a range or family-level figure is shown, confirm the exact rating for the complete model code and operating conditions before specifying a replacement.

Applications

Danfoss positions DDP within Dextreme hydraulic systems for excavators. The exact pump and controller configuration must be checked against the machine and its control architecture.

In open-circuit applications, the pump supplies controlled flow to the hydraulic system. The system design and selected controls determine how that flow is delivered to machine functions. The listed application sectors help frame the product search, but do not replace checks against the machine, installation space, duty and interface requirements. Please include those details with an enquiry so the requested version can be assessed.

Key features and compatibility

The Digital Pump Controller activates individual pistons to respond to hydraulic demand. Danfoss describes DDP as the core pump technology in Dextreme SWAP and FLEX excavator systems; compatibility depends on the complete pump code, controller and machine system.

Danfoss and related model names are used for technical identification. INTEREQ is independent and not an authorized Danfoss distributor. Availability is on request and subject to confirmation.

Pump selection starts by confirming the required circuit type and flow demand, then checking pressure limits, drive speed and control arrangement. Shaft, mounting face, port layout, rotation, charge or auxiliary provisions can vary between versions. These details should be checked together against the machine documentation; a matching family name by itself is not a fit confirmation.

Model identification and replacement compatibility

For a replacement review, send the complete Danfoss type code or a clear nameplate photo, together with the machine make, model and the component’s role in the circuit. If available, include the existing displacement, operating pressure and speed, connection drawing, and any control or accessory codes. This helps distinguish a family-level match from a configuration that fits the installed system.
