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
