We have released an interview video featuring Yamada employees about the "Seven Challenges."

We are currently offering a catalog introducing over 150 basic models of air-driven diaphragm pumps with intrinsic safety explosion-proof specifications.

From the ultra-compact model series 5, which is palm-sized, to the large series 80, we offer a total of 9 types, with 9 types of wetted materials and 7 types of diaphragm materials, providing over 150 basic models. It is possible to select models suitable for the usage conditions, and it can also transfer flammable liquids and liquids with abrasive elements. 【Features】 ■ Powered by compressed air, making it safe and eliminating the need for explosion-proof measures ■ Capable of transferring slurry liquids (liquids with solids and high abrasiveness) ■ Discharge volume can be adjusted and stopped by operating the air regulator ■ Fully self-priming, so no priming water is required ■ No mechanical seals, eliminating concerns about liquid leakage or failures due to dry running ■ Simple structure makes maintenance easy, and after-sales service is thorough. Fewer parts make maintenance straightforward. Equipped with a reset button to reduce downtime. 【Examples of Applications】 Recovery of waste liquids/sludge, transfer of factory wastewater, transfer of alcohol/ethanol, transfer of lubricants and hydraulic oils, paint supply to roll coaters, supply to filter presses. *For more details, please download the PDF or contact us. You can view the digest version from the 【Catalog Download】.

A diaphragm pump made of PTFE resin that allows for the large supply of strong acids, strong alkalis, and other chemical solutions! Flow rate can be adjusted with a regulator, making it easy to operate.

The BTT series is a diaphragm pump designed for chemical applications, utilizing fluororesin in all wetted parts. It employs highly corrosion-resistant PTFE resin, enabling the large-scale supply of strong acids, strong alkalis, and other chemical liquids. It operates on compressed air and is designed to be intrinsically explosion-proof, ensuring safe use. Features: - The body and diaphragm materials are made of fluororesin (PTFE)! - Since fluororesin is used in all wetted parts, it allows for the transfer of strong acids and strong alkalis. - High performance with a discharge rate of 125L/min! (NDP-P25BTT) * The discharge rate is only a guideline and may vary depending on the operating conditions of the diaphragm pump. For more details, please contact us or download the catalog.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.
