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, matching 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-disc structure ensures no failures, significantly reducing maintenance costs. 【Features】 ■ No water hammer ■ Excellent characteristics ■ Easy to handle ■ No water flow detector *For more details, please refer to the PDF document or feel free to contact us.

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, such as water, to about one-eighth. By rapidly rotating the impeller installed inside the pump, it separates the gases contained in the liquid through centrifugal force. This efficiently removes the 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 a crucial 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. ■ Custom devices suitable for sanitary specifications and large-capacity defoaming can also be manufactured. ■ Equipped with self-priming and pressurizing functions, it can achieve numerous processes such as suction, stirring, defoaming, degassing, and pressure delivery all in one machine. *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce our self-priming multi-stage centrifugal pumps, the 'USM/UBM/MEF models.' Thanks to the patented self-priming (air-water separation) mechanism, these pumps exhibit outstanding self-priming capability. The simple structure without an inlet check valve makes them durable and easy to maintain. We offer a range of models including the versatile "USM model," which features a direct connection to a 4-pole motor and is equipped with a self-priming mechanism, as well as the "UBM model" and "MEF model." 【Features】 ■ High-lift type with advanced self-priming mechanism ■ Excellent self-priming performance ■ Self-balancing mechanism ■ Variety of materials available *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 maintains a specified flow rate regardless of fluctuations in primary pressure, thanks to its built-in control functions. By adopting a balanced structure, the flow setting operation requires low torque and is independent of the 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 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.

• Flow Control

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, it enables reliable liquid level control 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 "UFSF-C Type" that is ideal for constant flow rate control under any conditions. 【Features】 ■ Compact float and compact water tank ■ Complete shut-off capability ■ Durable and maintenance-free ■ Full-range constant flow rate function (UFSF-C Type) ■ Proven performance *For more details, please refer to the PDF document or feel free to contact us.

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 outstanding 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 types, 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】 ■ Outstanding 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.

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 lift ranges. The casing is designed with a horizontal split at the top and bottom, allowing for internal inspection of the pump simply by removing the upper cover without disassembling the piping or bearings. By linking with a unique air extraction pump (patented) that has an air-water separation mechanism, it can self-prime even with suction piping that has a peaked configuration over a 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 materials or feel free to contact us.

The "YM type" is a large-capacity, high-efficiency spiral axial flow pump that has pursued its operating range to the limit with a single suction and single stage design. The wetted parts can be configured to accommodate various liquid qualities, such as chemical agents and discharged gypsum slurry. Since the wetted parts are all metallic, it is free from unexpected complaints related to rubber linings and similar issues. Due to the single suction design, inspection from the suction cover side is possible, and disassembly inspection can also be performed from the coupling side using a back pull-out method, significantly reducing maintenance time. 【Features】 ■ Large capacity and high lift ■ Compatible with various liquid qualities ■ All metallic ■ Reduction in maintenance costs ■ Abundant material options ■ Self-priming due to linked air extraction (optional specification) *For more details, please refer to the PDF document or feel free to contact us.

The product is a spiral pump linked with a gas-water separation blade and an exhaust pump. The gas-water mixture gathered 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 air bubbles. ■ Can continuously suction and transfer liquids mixed with solids, 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 wave shapes, over hills, etc. ■ With a rational structure, it offers high reliability, easy maintenance, and economical automatic operation. *For more details, please refer to the PDF document or feel free to contact us.
