1. Intravane pumps with hydraulic balancing structure provide more stable performance and longer life since less pressure from vane on stator.

2. Twelve vane system provides low amplitude flow pulsation resulting in low system noise characteristics.

3. Various displacement and shafts with 4different outlet opposite position make operation more flexible.

4. The cartridge is independent of the drive shaft, allowing for easy servcing withoyt removing the pump from its mounting.
