This pump uses a gear with teeth named lunary (patented), and rotates in conformity to continuous one-point contact. The conventional one-point contact gear (segmental gear, sinusoidal gear, etc.) is based on correction of the theoretical curve, so the slippage ratio tends to increase. However, the lunary gear provides a highly durable pump with small slippage ratio because an ideal closed curve is gained from a theoretical straight line and ellipse.
- Pulsation and noise are extremely limited due to lack of confinement.
- This pump is effectively used for highly viscous oil due to no cavitation.
- It has the durability thanks to the use of a patented lunary gear.
- The shaft input is low and it's economical.
