D1P open circuit high power axial piston pumps

High power and reliability

The D1P pump family meets the highest pressure and flow needs of new machine applications requiring variable displacement open-circuit flow. Designed for heavy-duty mobile and industrial applications in the high-pressure range (up to 350 bar), the D1P family is available with a variety of control options and is robust for harsh conditions.

Optimized system design

When you equip your machine with D1P pumps, choosing valves and controls that are made to work together can truly optimize your machine. D1P pumps are PLUS+1® compliant and our electronic controls are ready to go with plug and play software using the Danfoss PLUS+1® GUIDE programming environnent. They are also the perfect match for PVG spool valves, providing efficient and precise machine movement across a wide range of flow requirements.

A broad portfolio for maximum control

D1P pumps can be equipped with a broad range of control options. In addition to a full range of standard pressure compensation and load sensing controls, we offer many controls for today’s electrified systems needing electronic actuation or power management.

Mechanical Torque Control (MTC) is ideal for applications needing cost effective torque limitation without implementing complex electronic control architectures. Help improve machine productivity by eliminating engine stalls in high demand conditions with MTC controls.

Electronic Displacement Control (EDC) is an excellent choice for simple and robust control of pump flow to machine functions. This control can reduce dependency on intermediate valves for motor applications, provide dynamic maximum displacement limitation for auxiliary flow functions, or provide power management for overload protection.

Robust design results in robust performance

The fundamental design of D1P products raises the standard of performance. D1P pumps use angled piston bores and spherical valve plates for high efficiency performance in the rotating group. Combined with available integral vane boost pumps, speed ratings are maximized, and a greater range of adverse inlet conditions can be tolerated. Equipped standard with low friction roller-element cradle bearings, durability is increased versus traditional sliding frictional bearings. For the most extreme market conditions, ATEX certifications are available on mechanical control configurations.
