Serial Advantage

• 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.
