No dust generation at all! The rotor speed is low, making the raw materials less likely to break.
The "Raw Material Transport System" adopts the DJM type with a single blade design, which is less likely to break raw materials due to its low rotational speed. Since it discharges the absorbed amount directly, it has high accuracy in measurement, and there is almost no wear on the rotor and casing. This system can transport water at about one-third the amount of conventional spiral pumps. 【Features】 ■ Type for raw material transport: DJM (single blade design) ■ Due to the low transport ratio, the diameter of transport piping and hoses can be reduced ■ Smaller power consumption and energy-saving compared to air transport (about 1/4) ■ Unlike air transport, raw materials and water are sufficiently mixed before preparation ■ There is no dust generation like in air transport ▼ For more details, please refer to the materials on the official website.

Cheaper and shorter construction time than demolition and transfer! Ideal for reinforcing conceptual stone masonry and for weed removal effects.
The stone wall mortar injection work involves injecting mortar (a mixture of cement, sand, and water) into the gaps between stones using mechanical pressure, which acts to "reinforce" the stone wall, "eradicate weeds," "improve drainage management," and "enhance aesthetics," thereby alleviating the concerns and burdens of owners managing stone masonry. The stone wall mortar injection by Arai Co., Ltd., which boasts over 30 years of experience and achievements, has been certified as a new technology (NETIS) by the Ministry of Land, Infrastructure, Transport and Tourism. 【Features】 ○ More cost-effective than demolition and reconstruction ○ Possible to shorten construction period ○ Ideal for reinforcing existing stone masonry and weed removal ○ Mortar injected through gaps between stones using mechanical pressure ○ Improved drainage management and enhanced aesthetics For more details, please contact us or download the catalog.
Oil backflow prevention & low vibration/low noise! With the adoption of a pressurized oil supply system, operation from atmospheric pressure to high vacuum is smooth.
The "Small Rotary Pump" is a product that operates smoothly from atmospheric pressure to high vacuum using a pressurized oil supply method. In particular, the RV series is designed to achieve smooth continuous operation not only at high vacuum but also at high throughput (high pressure), incorporating an oil flow adjustment valve. It completely prevents oil backflow during sudden stops, such as power outages, keeping the system in a vacuum state. Additionally, due to precision machining and a special oil supply method, it has extremely low vibration and noise, with the RV series operating at around 48 dB(A). 【Features】 ■ Smooth operation from atmospheric pressure to high vacuum using a pressurized oil supply method ■ Oil backflow prevention mechanism ■ Low vibration and low noise ■ Complete prevention of oil backflow during sudden power outages *For more details, please refer to the PDF document or feel free to contact us.
Moisture-retaining jacket built-in type JW model
This is a pump that incorporates a jacket function in a W shape. It is capable of maintaining the temperature of the transferred liquid using steam, thermal oil, etc. A rotary pump is structurally a type of rotary pump and is classified as a positive displacement pump in principle. This rotary pump has two fan-shaped blades inside the casing, which rotate in sync via a pinion gear, and there is no contact between the blades. Additionally, there is no contact with the casing or cover. As the blades rotate, the chamber pressure on the suction side (the pressure in the space between the two blades and the casing) decreases, allowing liquid to enter. As the blades continue to rotate, the liquid moves along the inside of the casing toward the discharge side. Furthermore, the blades interlock, and the liquid is discharged from the pump.

![[Case Study] Elimination of Foreign Matter Contamination During Concentrated Juice Transfer](https://image.mono.ipros.com/public/product/image/da4/2000583506/IPROS81336010977964341166.png?w=280&h=280)
Eliminating foreign matter contamination with existing rotary pumps! A case study from a food manufacturer.
The food manufacturer was transferring concentrated fruit juice (with a maximum viscosity of 20,000 mPa·s) from the raw material tank to the filling machine tank at a flow rate of 2 tons per hour. However, the existing rotary pump had issues where wear particles were generated from the pump's mechanical seal, which could mix into the liquid, necessitating frequent disassembly and inspection. For solutions to the challenges and requests, please download and view the PDF document. 【Customer's Challenges and Requests】 ■ There was a risk of bacterial contamination every time the pump was disassembled, as it came into contact with outside air. ■ Maintenance costs were high due to the need for specialized maintenance personnel and the high cost of replacement parts. ■ Frequent disassembly and inspection were required because wear particles from the pump's mechanical seal could mix into the liquid. *For more details, please refer to the PDF document or feel free to contact us.
