Website Renewal! Celebrating 122 Years, When it Comes to Dry Vacuum Pumps and Rotary Blowers, Think of Unosawa Ironworks.

Energy-saving and maintenance-free! Compact air-cooled dry vacuum pump for clean processes.

The "KTS type" is a lightweight and compact air-cooled dry vacuum pump. Due to its durable Roots design, it has a long maintenance cycle and can also exhaust water vapor. It is ideal for non-corrosive gas applications that require clean vacuum and high reliability without oil back-diffusion. 【Features】 ○ Clean vacuum ○ Air-cooled ○ Lightweight and compact ○ Strong against water vapor and mist ○ Low noise and low vibration For more details, please contact us or download the catalog.

• Vacuum pump

Multi-purpose series! Rotary blowers developed based on extensive experience and achievements.

The ARJ type is a rotary blower (Roots blower) that incorporates a three-lobe rotor and combines the technology of Unosawa Group Co., Ltd. to achieve high performance, low noise, and low vibration. This series is highly standardized and can be used widely from low pressure to high pressure and from low flow rates to high flow rates. It also accommodates special gases, low-temperature fluids, and high-temperature fluids. 【Features】 ○ High reliability ○ Support for special specifications ○ Selection of optimal shaft sealing structure ○ Support for special materials and surface treatments ○ High pressure resistance specifications available For more details, please contact us or download the catalog.

• Positive Displacement Pump

Extremely robust against condensate! Vertical dry vacuum pump for chemical processes.

The "TRV Series" is a versatile dry vacuum pump (Roots vacuum pump) uniquely developed as a vacuum pump that is strong against condensable gases. The gas flow path is arranged to flow from the top to the bottom in a Down-Flow manner, allowing mist and liquids condensed inside the pump, which are drawn in with the gas, to easily flow down to the discharge port and be expelled or collected under atmospheric pressure. Therefore, it is an extremely robust pump against the inflow of mist and condensate from gases. In addition to the standard FC material, corrosion-resistant materials are also available for selection. 【Features】 ○ Strong against liquids ○ Energy-saving and high-performance design ○ Low temperature rise ○ Capable of drawing high-temperature gases ○ Small installation footprint For more details, please contact us or download the catalog.

• Other pumps

Ideal for the suction of condensable gases! General-purpose dry vacuum pump for chemical processes.

The "TRM Series" is a general-purpose dry vacuum pump (Roots vacuum pump) with many years of experience and numerous achievements. It can operate efficiently and stably at a consistent temperature thanks to the intermediate cooler. Additionally, it is capable of recovering condensates such as solvents and is suitable for suctioning condensable gases in vacuum drying, distillation, and degassing processes. The dry vacuum pump can cover a wide exhaust speed range from approximately 2m³/min to 35m³/min, and it can also accommodate special specifications made of corrosion-resistant materials such as stainless steel. 【Features】 ○ Wide operating range ○ Completely dry ○ No water contamination ○ Long-term continuous operation For more details, please contact us or download the catalog.

At construction sites, temporary parking lots may be established for workers and construction-related vehicles. On unpaved ground, mud and ruts can easily occur due to rain, which may hinder vehicle access. Hyper CLT mats are civil engineering materials that utilize wood CLT. By laying them in temporary parking lots, a suitable environment for vehicle passage and parking can be created while protecting the ground. They can be laid only in the necessary areas, and after the construction is completed, they can be removed and repurposed for temporary roads or access routes. The 5×10 panels weigh approximately 230 kg, and the 5×20 panels weigh about 460 kg, making them lightweight and easy to install and remove even with small machinery, allowing for changes in parking space. Additionally, they offer benefits unique to wood, such as glare reduction, noise reduction, and CO2 fixation. They are registered as a technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS as "TH-250021-A," and can be utilized for the development of temporary parking lots and innovative public works.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can change the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment 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.
