Detailed Engineering Overview
Nachi Fujikoshi PVS series variable displacement piston pumps feature patented Japanese semi-cylindrical swashplate supports and double balance plates. These design breakthroughs suppress pressure ripples by up to 50% compared to conventional pumps while minimizing operational noise to whisper-quiet levels.
Key Performance Features
- Whisper quiet operation (<62 dB(A) at 210 bar)
- Sharp pressure compensation cut-off saves massive electrical energy
- Dual pressure adjustment and load-sensing control configurations
- Extremely compact footprint allows tight integration inside machine power units
