Cycle experiment, the Japanese enterprise finally broke the hard and brittle material problem
Rotor Pump With Water-proff Cover
We are a world-leading technology-based enterprise
focus on R&D and manufactures non-Newtonian fluid conveying equipment. We
specialize in rotary pumps, homogeneous pumps and grinding pumps. We have
obtained 11 invention Patents and 46 practical patents, and won many national honorary
titles.
Twin-rotor
lobe pump are multi-functional and bi-directional positive displacement pumps,
produced with fine technology. These products use synchronic rotors, driven by
a pair of synchronic gears in the gear box. Transmitted by the main shaft and
the sub-shaft. The rotors move synchronically in counter-clockwise a
directions, which, consequently, varies the pump capacity and builds up high
vacuum capacity and emission pressure. It is particularly suitable to pump
sanitary medium, high-corrosive and high-viscous medium.
Rotor
pump with water-proff cover: The pump is equipped with a detachable protective
cover for the whole machine, and the material is S.S., it can protect the
motor, coupling and other parts from corrosion during on-site cleaning.
In
the past 30 years, we dedicate to provide the scientific and professional
solutions in fluid field. In the field of complex fluid transportation, our
company's R&D technology, manufacturing technology, application technology is
at the leading position in the world.
Durrex pumps can be widely used in food, consumer chemical, refined
chemical, paper making, chemical fiber, pharmaceuticals, coating, etc. We will
continue to focus on scientific research and innovation, improve the level of
precision manufacturing, and continuously promote the intelligent development of
fluid transportation industry, to create greater value for global users

One notable example is the machining of a silicon carbide (SiC) adsorption plate used in semiconductor manufacturing. This component is a disk-shaped part with a diameter of 290 mm and a thickness of 10 mm. It features 10 concentric grooves, each 1 mm wide, on its surface. Due to SiC’s extremely high Vickers hardness—about 1.3 times that of Al₂O₃—traditional machining methods are not effective. Instead, TOP Seiko uses a super-hard diamond-coated drill bit made from a special alloy. Although this tool is very rigid, it is also fragile and wears quickly. To address this, the company developed a specialized technique using two custom-made tools equipped with rectangular diamond segments (800 μm in width) on the bottom of an open disc. By rotating the tool on a machining center (MC), they can efficiently cut the required grooves into the workpiece.
In addition to ceramics, TOP Seiko also works extensively with metals like tungsten and molybdenum. For instance, when processing molybdenum rods on an NC lathe, the company uses a self-designed cutter to process hundreds of units at once. This method significantly extends the tool life, allowing for up to 40–50 hours of continuous, unmanned operation. Another unique approach involves clamping tungsten sheets without a traditional chuck. Instead, the material is fixed to a jig using adhesive, ensuring that no portion of the sheet is wasted due to clamping. This allows for full utilization of the material, which is especially important when working with expensive or rare materials.
According to industry reports, TOP Seiko excels in handling difficult machining tasks efficiently. Beyond their 12 years of accumulated expertise, the company relies on a collaborative problem-solving approach. When faced with a challenging task, operators and on-site staff engage in a process called "looping." This involves three main steps: first, observing the phenomenon before, during, and after processing; second, forming hypotheses based on those observations; and third, testing these hypotheses through actual machining. Through repeated cycles of observation and trial and error, the team has developed unconventional but highly effective techniques that often defy traditional machining logic.
Overall, TOP Seiko stands out in the field of precision machining by combining advanced technology, innovative methods, and a deep understanding of material behavior. Their commitment to continuous improvement and hands-on problem-solving makes them a key player in the production of high-quality components for cutting-edge industries.
