This is the replacement procedure for the consumable parts diaphragm and valve. It can also serve as a reference for the maintenance procedures of other micropumps.

The maintenance procedures for the other gas pumps are generally similar, so please refer to them.

SPACECOOL Inc. has received the Excellence Award in the "JA Accelerator Program 8th Term," an open innovation program hosted by the "AgVenture Lab," an innovation lab by eight JA Group organizations nationwide, which supports startup companies with innovative ideas and technologies in the agriculture, forestry, and livestock sectors. In this program, startups that passed the preliminary screening from a record number of over 270 applications presented at the final selection meeting held on May 21, 2026. During this event, our company proposed a new solution utilizing the radiative cooling material "SPACECOOL" to maintain and improve productivity in the agriculture and livestock industry and to reduce the risk of heatstroke for agricultural workers, earning the Excellence Award. Due to the worsening heat waves associated with recent climate change, the importance of heat countermeasures in the agriculture and livestock industry has increased. Taking this recognition as an opportunity, our company aims to further contribute to various challenges related to heat in the agriculture and livestock sector through the radiative cooling material "SPACECOOL." Additionally, to accelerate our expansion into the agriculture, forestry, and livestock sectors, we will participate in the upcoming "Livestock Week" this month to recruit demonstration sites.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs often change the base material around the crack due to heat, leading to residual stress and deformation, which constantly carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made 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 or download the catalog.

On our company's website introducing vehicle detection sensors, you can easily find products that meet your needs from three categories: "Purpose of Use," "Location of Use," and "Product List." [Introduction to Vehicle Detection Sensors] The sensors detect the passage of vehicles and notify you with a rotating light or switch the display of parking availability. They contribute to safe driving within parking lots and smooth management operations. They are used in various areas, from coin parking to large-scale parking lots. We will continue to improve our webpage to provide information about Hotron's "Vehicle Detection Sensors."
