D1P145 Axial Piston Pump
The 145 cm³ workhorse of the D1P open circuit family for construction and material handling machines.
Product Overview
Built around 145 cm³, the D1P145 is a core size of the Danfoss D1P range, flowing 319 L/min in standard trim and 363 L/min with the boost impeller for the hard-working circuits of construction and material handling machines.
Angled piston bores and spherical valve plates hold efficiency high at its 350 bar continuous rating, while roller-element cradle bearings extend service life under shock-loaded duty - the stops, starts and load spikes typical of crane and excavator work.
The control menu spans pressure compensation, load sensing, mechanical torque control (MTC) and electronic displacement control (EDC). PLUS+1-compatible electronics pair cleanly with Danfoss PVG 128 valve systems, so the pump behaves as part of an integrated machine architecture rather than an isolated component.
Core Advantages
Spherical valve plate design sustains volumetric efficiency at full working pressure.
Roller-element cradle bearings handle repeated peak torque better than sliding designs.
PC, LS, MTC and EDC builds cover mechanical machines and electrified platforms.
PLUS+1-compatible electronics and PVG 128 valve matching simplify machine control design.
Key Selling Points
Standard and impeller-boosted builds give machine builders a flow upgrade path on the same SAE D mounting.
The 145 cm³ class is widely applied to concrete pump and crane circuits that alternate between idle and full flow.
Full 350 bar continuous rating delivers force without adding frame size.
EDC and PLUS+1 support let OEMs move from hydraulic pilot control to electronic machine control at their own pace.
Send machine make, model and the old pump part number - we match control and shaft configuration before quoting.
Mechanical control configurations can be supplied with ATEX certification for hazardous-zone installations.

Frequently Asked Questions
Yes - the D1P145 is rated for 350 bar continuous working pressure, with 400 bar permitted intermittently. Duty-cycle data should be checked for sustained peak operation.
145 cm³ sits in the sweet spot between flow capacity and frame size for many construction machines - enough flow for heavy functions without moving to the larger SAE E frame.
Both displacements share the SAE D envelope, so frame geometry is consistent - porting, shaft and control differences must still be verified against the machine before changing displacement.
Load sensing is common where flow varies with load. Pressure compensation suits constant-pressure duties. Tell us your circuit layout and we will advise the best control for the build.
Yes - D1P pumps are the recommended partner for PVG 128/256 spool valves, and PLUS+1-compatible controls allow electronic matching of pump and valve response.
Machine make and model, the old pump part number, and a photo of the nameplate if available. We confirm control, shaft, rotation and mounting from that information.
ATEX certification is available on mechanical control configurations for hazardous environments - confirm the required zone classification with us when enquiring.
The roller-element cradle bearing design is a key durability feature. Follow the recommended filtration, oil cleanliness and suction conditions for the frame, and service parts are available on request.
