Do you have concerns about choosing a pump, such as 'I want a model equivalent to the pump I'm currently using,' 'How durable is it?' or 'I want to try it, but I'm worried about cavitation'?

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】.

• Other pumps

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.

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 affecting the base material with heat. 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.

Parking space management refers to the real-time display of parking availability and the management of efficient use of parking spaces. By utilizing Hotron's sensors, drivers can quickly discover available parking spaces, enabling efficient parking lot operations. For large parking lots, we recommend the "Floor Management Method" and "Block Management Method," which focus on cost reduction. Sensors are installed at regular intervals to count and manage the number of passing vehicles. This method offers the advantages of easy installation and low costs. 【Target Products】 - Vehicle Count Sensor CCS2 - Ultrasonic Sensor HM-UX2/UW2 For smaller facilities, we recommend the "Parking Space Management Method," where sensors are installed in each parking space to display availability with high accuracy. By providing reliable occupancy information, this method helps reduce unnecessary entry of new vehicles and ensures safe parking lot operations. 【Target Products】 - Occupancy Detection Sensor HM-UX2/UW2 - Occupancy/Pass Detection Sensor HM-LC6 - Occupancy Detection Sensor HM-LC7/LC7-FLS - Occupancy/Pass Detection Sensor HM-S6 - Occupancy Detection Sensor HM-S8

In facilities operating nurse call systems, we have made bed exit sensors wireless, allowing them to notify in conjunction with the nurse call system. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensors wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ Bed exit sensors wirelessly notify in conjunction with the nurse call system. ○ Up to 5 transmitters can be registered with a single receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.
