GPL [patented lunary gear pump]



Structure

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.

Features

  1. Pulsation and noise are extremely limited due to lack of confinement.
  2. This pump is effectively used for highly viscous oil due to no cavitation.
  3. It has the durability thanks to the use of a patented lunary gear.
  4. The shaft input is low and it's economical.
