Digital Displacement® Pump

Digital displacement is a new revolutionary hydrogenerator based on the principle of a radial piston hydrogenerator. The cooperation of the Danfoss Digital Displacement® hydrogenerator (DDP096) with the control unit (DPC12) offers the hydrogenerator with the highest efficiency on the market.
The DPC12 control unit controls each piston individually using On / Off valves, which changes the geometric volume of the hydrogenerator. This achieves the required flow quickly and accurately. DDP096 has high efficiency and very low idle losses.

Features and benefits of DDP096 and DPC12 include:

• Radial piston hydrogenerator with exceptional efficiency even at partial load
• Geometric volume 96 cm3
• Working pressure up to 420 bar
• Low power losses at idle, even when the hydrogenerator is under pressure
• Direct digital control
  • Fast response, small hysteresis of geometric volume
  • CAN-bus interface with power monitoring and control and monitoring of diagnostic information, adjustable parameters
• Virtually no oil leakage at zero flow
• From zero to full geometric volume (or back) in 3/4 turn (24.7 ms at 1850 rpm)
• Possibility of several independent outputs from one hydrogenerator, possibility of a continuous shaft for tandem needs
