D1P Series D1P060 D1P065 D1P65 D1P130 Hydraulic Piston Sundstrand Sauer D1P145 D1P193 D1P260 Pump
The D1P145, D1P193, and D1P260 are all Danfoss D1 series heavy-duty open variable axial piston pumps, designed for high-pressure, high-flow-rate applications under extreme conditions, making them the mainstay pumps in heavy equipment hydraulic systems.
Key Common Features:
Basic Design: All pumps utilize a 9-piston rotating assembly, conical cylinder, and spherical distributor plate design, providing strong self-priming capability and smooth operation. They feature built-in low-friction roller bearings, offering superior durability compared to traditional sliding bearings.
Pressure and Speed: Continuous operating pressure reaches 350 bar, with intermittent pressure up to 400 bar; an integrated booster pump is optional, allowing for a maximum speed of 2500 rpm and high power density.
Control Options: Supports multiple control methods including pressure compensation, load sensitivity, mechanical torque control, and electronic displacement control (with manual override). Some mechanical control configurations are ATEX certified, suitable for hazardous environments.
System compatibility: It can be seamlessly integrated with Danfoss PVG128/256 high-flow multi-way valves to form a complete hydraulic system solution. It is also compatible with the PLUS+1® GUIDE programming environment, which facilitates the customization of control logic.

Typical Application Scenarios
All three pumps are suitable for extreme working conditions, specifically applicable equipment including:
Construction and Engineering Machinery: Concrete pumps, excavators, cranes, road tunneling machines;
Special and Industrial Equipment: Mining drilling rigs, port container cranes, material handling equipment;
Marine and Energy Equipment: Marine vessels, oil and gas field extraction equipment, industrial power stations.
Among them, the D1P260, as the largest displacement model in the series, is particularly prominent in heavy-duty equipment requiring ultra-high flow output.
Selection and Usage Considerations
Prioritize selecting the model based on the required flow rate of the equipment: select D1P145 for small flow requirements, D1P193 for medium to high power applications, and D1P260 for ultra-high flow scenarios.
During installation, pay attention to the rotation direction (supports clockwise/counterclockwise rotation, observed from the shaft end), and the suction port pressure must meet a minimum absolute pressure requirement of 0.6-0.8 bar.
During maintenance, attention should be paid to the boundary filter (designed by Danfoster), which filters the control oil through the gap between the valve core and the valve orifice, preventing the control valve from sticking. Its cleanliness needs to be checked regularly.
