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 processing of a silicon carbide (SiC) adsorption plate used in semiconductor manufacturing. This component is a disk-shaped part measuring 290 mm in diameter and 10 mm in thickness, featuring 10 concentric grooves, each 1 mm wide. Due to SiC's extreme hardness—about 1.3 times that of alumina—traditional machining methods are not effective. Instead, TOP Seiko uses ultra-fine diamond-coated drills made from super-hard alloys. However, these tools are fragile and wear out quickly. To address this challenge, the company developed an innovative method using two custom-made tools equipped with rectangular diamond segments (800 μm wide) on the bottom of a disc-shaped tool. By rotating the tool on a machining center, they can cut precise circular grooves into the workpiece efficiently.
In addition to ceramics, TOP Seiko also processes metals like tungsten and molybdenum, often using unconventional techniques. For instance, when machining molybdenum rods on an NC lathe, the company employs self-designed cutters that allow for continuous, unattended operation for up to 40–50 hours. Another unique approach involves clamping tungsten sheets without a traditional chuck, instead securing them with adhesive on a custom jig. This ensures that the entire sheet can be used without any material being lost due to clamping pressure.
According to industry reports, TOP Seiko’s success stems not only from its technical capabilities but also from its culture of problem-solving. When faced with particularly challenging machining tasks, the company relies on a collaborative, iterative process known as "looping." This method involves three key steps: first, observing the entire machining process before, during, and after; second, forming hypotheses based on those observations; and third, testing those hypotheses through trial and error. Through this cycle of experimentation and refinement, the company has developed several unconventional yet highly effective machining techniques that defy traditional expectations.
