D1P open-circuit high-power axial piston pumps
We design D1P pumps to meet the tough pressure and flow demands of today's variable-displacement open-circuit applications. Built to withstand harsh conditions in heavy-duty mobile machines, they are available globally with displacements up to 260 cm3 [15.87 in3], maximum working pressures of 350 bar [5,076 psi], input speeds up to 2,500 rpm, and a variety of control options.
Features and benefits
- Broad control options, including mechanical torque (MTC) and electronic displacement (EDC) controls
- Most power dense 160 cm3 [9.76 in3] pump on the market
- Available integral boost pump for higher speeds
- Angled piston bores and spherical valve plates for highest performance
- Roller cradle bearing for incredible durability
- ATEX certifications available
