Danfoss D1P130 Variable Displacement Piston Pump – 130cc
Load-sensing capable mid-displacement pump on the SAE D frame shared with the D1P145.
Product Overview
The D1P130 delivers 130 cm³ of variable displacement for mid-flow open circuits, producing 286 L/min in standard form and up to 325 L/min when specified with the integral impeller boost stage. The boosted variant also lifts the continuous speed rating, which matters when the prime mover runs fast.
It mounts on the standard SAE D flange and shares its envelope with the D1P145, giving machine builders one mounting family across two flow classes and simplifying retrofit planning. A machine designed around the frame today can grow into the larger displacement tomorrow without a pump-compartment redesign.
Rated at 350 bar working pressure with 400 bar peaks, the D1P130 suits load sensing circuits on excavators, concrete pumps and cranes, where matching flow to demand directly cuts fuel and heat load.

Core Advantages
One mounting family, two displacements - simpler machine platforms and easy upgrades.
Integral impeller raises continuous speed to 2,500 rpm and tolerates harder inlet conditions.
Flow-on-demand control trims fuel and heat in partial-load excavator and crane cycles.
Full family pressure rating with 400 bar peaks for demanding duty cycles.
Angled bores, spherical valve plates and roller cradle bearings as standard.
Pairs with PVG 128 valves and PLUS+1-compatible electronics for matched machine systems.

Frequently Asked Questions
Theoretical flow is 286 L/min at 2,200 rpm in the standard build and up to 325 L/min at 2,500 rpm when the integral impeller boost stage is fitted.
The SAE J744 152-4 flange and DIN 5480 W50 shaft match the common SAE D mounting pattern. Compare porting positions and control type with your existing unit before ordering.
Choose it when the prime mover runs above 2,200 rpm or when inlet conditions are marginal - the impeller supports 2,500 rpm continuous operation.
The two displacements share the same mounting envelope and family design. Specific internal and control components differ, so always quote using your part number.
350 bar working pressure continuously, with 400 bar intermittent peaks - the same family rating across the D1P range.
Pressure compensation, load sensing, mechanical torque control (MTC) and electronic displacement control (EDC) are available depending on the build specification.
Rotation is set by the build. Tell us the rotation of your current pump - CCW or CW viewed from the shaft end - and we will confirm it against the model code.
Yes - D1P pumps are designed to work with PVG 128/256 spool valves for an optimized machine system, and PLUS+1-compatible controls integrate with machine electronics.
