Max. continuous inlet pressure: 200bar Outlet pressure at 167bar
HRD Series Orbital Hydraulic Motor,it is a spool
distrabution motor,adopts needle tooth ring and star
design,low start-up pressure,high efficiency and high
reliability.
• It adopts spool distribution structure, small size and light weight. • The high-pressure shaft seal can carry high back pressure and allow series and parallel use. • It adopts advanced rotary stator parameter design, low starting pressure, high efficiency, and high reliability and smooth operation. • Reinforced drive link design for long service life. • Multiple displacements and mounting sizes are available.
