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. 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.

• Other pumps

Maximum discharge capacity of 840L/min*! A large model with a discharge diameter of 3 inches. Air-driven, suitable for various applications such as waste liquid recovery and the transfer of flammable liquids.

The "NDP-80 Series" is a large air-driven diaphragm pump, ideal for oil plants and marine applications. 【Features】 ■ Maximum flow rate of 840L/min (excluding models with fluororesin diaphragm and GF polypropylene body) ■ Selection of models suitable for operating conditions is possible with four types of body materials and nine types of diaphragm materials. ■ Capable of transferring slurry liquids (solids and highly abrasive liquids) due to the use of ball valves. 【Examples of Applications】 Collection of wastewater/sludge, transfer of factory wastewater, transfer of alcohol/ethanol, transfer of lubricating oil and hydraulic oil, paint supply to roll coaters, supply to filter presses. 【Main Specifications】 ○ Nominal diameter: 3" (80mm) ○ Operating air pressure: 0.2 to 0.7MPa ○ Maximum discharge pressure: 0.7MPa ○ Slurry limit (maximum passing particle diameter): less than 10mm 【The NDP-80 Series is made to order, so please be sure to check the delivery date.】 * The flow rate is only a guideline and may vary depending on materials, liquids being transferred, piping conditions, etc. * For more details, please refer to the materials and catalog.

Are you making progress on measures for the "2024 Problem"? With stricter management of drivers' working hours, reducing "waiting time" has become an urgent issue in the logistics field. To address this challenge, our company, Hotron, proposes the "Vehicle Detection Ultrasonic Sensor 'HM-UX2'," which instantly grasps the availability of loading bays. The 'HM-UX2' contributes to the resolution of waiting times by accurately understanding the availability situation, reducing unnecessary waiting and queueing, and shortening waiting times to alleviate the burden on drivers! By replacing the "eyes" of your loading bay management with this high-precision sensor, why not start addressing the "2024 Problem"? Take a look at the product features: "Can it accurately detect availability?" "Can we really use it in our company?" "I just want to know the cost, even if it's an estimate." If you have any questions or requests, please feel free to consult with us.

Dear Valued Customers, Thank you very much for your continued support. We would like to inform you that our company will be closed for summer vacation from Wednesday, August 13, 2025, to Friday, August 15, 2025. We will resume normal operations on Monday, August 18. We appreciate your understanding and cooperation.

Technoa Co., Ltd. (Headquarters: Gifu City, Gifu Prefecture, Representative Director: Koji Yamazaki) will hold a limited-time summer special event, "Monozukuri DX CAMP," from Saturday, August 9, 2025, to Saturday, August 23, 2025. Small and medium-sized manufacturing companies face challenges such as a shortage of specialized personnel and a lack of know-how and information, which act as barriers to promoting DX (digital transformation). This event will provide a step-by-step approach to "realistic DX," based on the know-how accumulated by Technoa while supporting the DX transformation of small and medium-sized manufacturing companies. It will be structured as DAY.1 to DAY.5, offering an opportunity for skill development during the summer break and supporting the learning and growth of small and medium-sized manufacturers.
