The manufacturing factory for diaphragm pumps has been completely renovated! We have released an introduction video for the new factory. We will expand our production capacity to meet customer needs.

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.

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.

Realizing Precision Control in Energy Innovation Hydrogen, fuel cells, CCUS, biofuels, CNT manufacturing. There are technologies on-site that monitor precise flows to support the energy of the future. Brooks Instrument's flow meters support the energy transition.

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.

We are pleased to announce that our company will be exhibiting at the "Monozukuri Fair 2025" held in Fukuoka. ECAD is a dedicated CAD solution for electrical design, equipped with a wealth of features for control design and power distribution panel design, developed for domestic electrical designers over the past 40 years. It addresses challenges such as improving design quality, enhancing operational efficiency, and reducing labor. At the venue, we will introduce the "Panel Manufacturing Skill-less Solution," which utilizes the panel manufacturing support system "WIRE CAM DX" to create pre-manufacturing information as a solution to the labor shortage issues in panel manufacturing that have traditionally required skilled workers. This enables less experienced operators to achieve high-quality manufacturing in processes such as wire processing, component assembly, and wiring work. We invite you to visit our exhibition booth. ■ Exhibition Name: Monozukuri Fair 2025 ■ Location: Marine Messe Fukuoka Hall A & B ■ Booth Number: Hall B BN-9 ■ Dates: October 15 (Thursday) to October 17 (Saturday), 2025 (3 days) ■ Hours: 10:00 AM to 5:00 PM (last day until 4:00 PM) *For more information about the exhibited products, please download the materials.
