• Parts and Materials

The "DP, ASP type" is a defoaming and degassing pump that, despite its compact size of about 1 meter in width, can reduce the oxygen in liquids to about one-eighth in the case of water. By rapidly rotating the impeller installed inside the pump, it separates the gases contained in the liquid using centrifugal force. This allows for efficient removal of gases by suctioning them with a vacuum pump. We also offer on-site demonstration operations (for a fee), and online remote demonstrations and meetings are possible. Please feel free to contact us when needed. 【Features】 ■ Instantly removes unnecessary foam and gas generated during the transfer and filling of liquid foods, etc. ■ Plays an important role in maintaining the quality and freshness of beverages, etc. ■ Contributes to a safe and secure food production system as it does not use chemical agents ■ Customizable to produce sanitary specifications and devices suitable for large-capacity defoaming ■ Equipped with self-priming and pressurizing functions, enabling numerous processes such as suction, stirring, defoaming, degassing, and pressure transfer to be achieved with a single unit * For more details, please refer to the PDF materials or feel free to contact us.

This product is a high-performance check valve (non-return valve) that safely and economically solves the significant issue of water hammer (water shock) in pumping and water supply systems. Its operation is quiet and matches a serene surrounding environment. Thanks to its patented structure, the valve opens and closes in response to flow without delay, preventing water hammer from occurring. The valve's loss of head is equivalent to that of JIS swing check valves (non-return valves), making it adaptable to a wide range of specifications. Even in large sizes, its simple single-plate structure ensures no failures and significantly reduces maintenance costs. 【Features】 ■ No water hammer ■ Excellent characteristics ■ Easy to handle ■ No water supply detector *For more details, please refer to the PDF document or feel free to contact us.

• Air compressors, blowers and pumps

The "YM type" is a large-capacity, high-efficiency spiral axial flow pump that has pursued the limits of its usage range with a single suction and single stage design. The wetted parts can be configured to accommodate various liquid qualities, including chemical solutions and discharge gypsum slurries. Since the wetted parts are all metallic, it is free from unexpected complaints related to rubber linings and similar issues. With its single suction design, inspection can be performed not only from the suction cover side but also from the coupling side using a back pull-out method, significantly reducing maintenance time. 【Features】 ■ Large capacity and high head ■ Compatible with various liquid qualities ■ All metallic construction ■ Reduction in maintenance costs ■ Abundant material options ■ Self-priming with linked exhaust (optional specification) *For more details, please refer to the PDF document or feel free to contact us.

• Air compressors, blowers and pumps

The "HD type" is a dual-suction volute pump that operates efficiently over a wide range of pumping volumes, has a low NPSHR, and can maintain stable operation up to high head usage ranges. The casing is designed with a horizontal split at the top and bottom, allowing for internal inspection of the pump by simply removing the upper cover without disassembling the piping or bearings. By linking a unique air separation mechanism (patented) with the pump, it can self-prime even with suction piping that has a mountain-shaped configuration exceeding the dam, enabling automatic pumping operation. 【Features】 ■ Wide operating range ■ Easy maintenance ■ Abundant material options ■ Self-priming with linked air extraction (optional specification) *For more details, please refer to the PDF document or feel free to contact us.

• Air compressors, blowers and pumps

This is a unique degassing device that can continuously degas, suck up, and transfer a liquid mixed with bubbles. It separates bubbles from the liquid with remarkable efficiency and extracts them using a vacuum pump, providing a stable supply of degassed and defoamed liquid. It operates mechanically without the need for chemical agents, ensuring safety for health and being environmentally friendly, while also reducing maintenance costs. <Features> - When the liquid mixed with bubbles flows in, the rotation of the inducer separates the gas and liquid, accumulating gas mixed with liquid. - The gas mixed with liquid transitions to the separation blades, and the remaining liquid is further separated before being discharged. *For more details, please download the catalog.

• Air compressors, blowers and pumps

The "UHN Series" is a self-priming vortex pump that achieves a negative pressure of 60 to 90 kPa due to its internationally patented air-water separation mechanism, demonstrating exceptional self-priming capability. Its simple structure without an inlet check valve makes it robust and easy to maintain. Typically, there is no need to install a foot valve or intermediate valve on the suction side. To accommodate various liquid qualities, we offer a wide range of materials, including FC, SCS, and corrosion-resistant and wear-resistant materials such as Yokota special stainless cast steel (YST). 【Features】 ■ Exceptional self-priming capability ■ No issues even if air mixes during pumping ■ Low NPSH ■ Simple structure without an inlet valve, no foot valve required ■ Capable of overcoming hills and long suction piping *For more details, please refer to the PDF document or feel free to contact us.

• Air compressors, blowers and pumps

This product is a spiral pump linked with a gas-water separation blade and an exhaust pump. The gas-water mixture collected at the center of the spiral pump is centrifugally separated into water and air by the rotation of the gas-water separation blade, with only air being suctioned and exhausted by the exhaust pump. The spiral pump operates under a constant state of high negative pressure and exhaust volume from the exhaust pump. Therefore, it does not cause air blockage in the spiral pump, and cavitation is less likely to occur, allowing it to consistently demonstrate stable, top-level pump performance during operation. 【Features】 - Capable of powerful continuous suction and transfer of high-viscosity sludge-like substances and liquids containing bubbles. - Able to continuously suction and transfer liquids mixed with solid materials such as food ingredients, muddy water with stones, and sewage mixed with empty cans. - No priming water is needed from the start. - The suction pipe can be freely laid out in various shapes, such as corrugated or over-the-hill shapes. - Its rational structure allows for high reliability, easy maintenance, and economical automatic operation. *For more details, please refer to the PDF document or feel free to contact us.*

The "Super Float UFSF Type" is a high-performance valve equipped with functions such as liquid level control and constant flow rate, which automatically stops when the liquid level reaches the upper limit. Thanks to its unique balance mechanism, reliable liquid level control is possible with a compact float, regardless of the inlet pressure. This allows for a significantly more compact water tank. We offer a standard type "UFSF-S Type" suitable for general use, and a full-range constant flow type "UFSF-C Type" that is ideal for constant flow control under any conditions. 【Features】 ■ Compact float and compact water tank ■ Complete shut-off capability ■ Durability and maintenance-free ■ Full-range constant flow function (UFSF-C Type) ■ Proven performance *For more details, please refer to the PDF document or feel free to contact us.

The "Uniflow Valve UF Series" is a direct-acting constant flow valve that automatically achieves the specified flow rate regardless of fluctuations in primary pressure, thanks to its built-in control functions. By adopting a balanced structure, the flow rate setting operation requires low torque and is independent of the water supply pressure. Its unique pressure reduction mechanism allows for a very small allowable cavitation coefficient to be set. With the built-in lift-type adjustment valve, it enables flow control that is close to linear characteristics, combining the functions of a constant flow and an adjustment valve, making it a user-friendly automatic control valve suitable for various applications. 【Features】 ■ Excellent constant flow characteristics (variable constant flow type) ■ Extremely low operating torque ■ Simple direct-acting design ■ Cavitation characteristics ■ Flow control characteristics ■ High performance *For more details, please refer to the PDF materials or feel free to contact us.
