◆Demo units of diaphragm pumps are available for loan◆ Campaign period: Until the end of September 2023

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.

Japan is among the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of significant earthquakes occurring. For the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake measures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" ◎ For more details, please download the materials or contact us.

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 even 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.
