  • A side view of the elicloid gear, our company’s unique technology.

    The ellicloid gear was developed as a liquid transfer pump.
    The one-point continuous contact tooth provides a high conduction efficiency, flexibility in design, and is easy to be machined.

    Ellicloid gear pump is a
    displacement type gear pump that uses an ellicloid gear.
    We can apply Kanigen plating to the casing, gear, shaft, etc. upon request.
    Excellent corrosion and abrasion resistance, and quiet operation even at high speeds, along with less cavitation;
    it is a high performance pump.

  • The locking phenomenon does not occur when using a one-point continuous contact tooth; the vacuum phenomenon and extreme high-pressure phenomenon also do not occur. It is a gear pump that is quiet, does not cause foaming of liquids, is highly efficient, and has a long life.
    Here are the details.

    Our company’s elicloid gear pump
  • The enclosed volume changes as the gear rotates, and wears quickly, vibrates, makes noise, and causes foaming.
    Here are the details.

What is an ellicloid gear pump?
Among rotary displacement pumps, our company’s ellicloid gear pump was developed as a liquid transfer pump and has adopted the one-point continuous contact tooth for its gear. It is a type of double helical gear pump.
It can transfer liquid efficiently with low vibration and noise levels.

What is a cloid rotary pump?
It is a rotary pump designed to withstand high-viscosity liquids and even the transfer of solution-containing solids.
It has two lobe rotors rotating synchronously through the timing gear, and causes no metal-to-metal contact.
Thus, change in the solution quality is minimal. Also, it can be easily assembled/disassembled, and cleaning is also easy.
