Achieve a continuous constant flow without pulsation, without using an air chamber! Measurement is possible with a flow meter!

The smooth flow pump "BPL Series" is diaphragm-type and achieves a continuous, pulsation-free flow without using an air chamber, allowing for measurement with a flow meter. There is no inconsistency in the injection and mixing of chemical solutions, enabling stable quality control at all times, and the power consumption is less than half that of air-driven pumps or rotary pumps. 【Features】 ■ Achieves a continuous, pulsation-free flow. ■ No mechanical seals, so there is no liquid leakage to the outside. ■ No need for an air chamber, eliminating piping vibrations due to air reduction and the risk of chemical spillage from air chamber damage. ■ The absence of pulsation allows for design with smaller and more cost-effective piping. ■ Since the flow is constant, the usage of chemicals can be managed with a flow meter. ■ Compared to conventional diaphragm pumps (300L/H class), CO2 emissions are reduced by approximately 50%. ★ For more details, please download the catalog. We also accept requests for loan units. Feel free to contact us.

A dedicated machine for injecting sodium hypochlorite with peace of mind. It features an inline automatic air release mechanism and a double block with an air block mechanism!

This is a dedicated pump for hypochlorite injection with a gas lock-free type. 【Features】 ■ Automatic air release mechanism that reliably eliminates sucked-in air Adopts a special valve seat mechanism (patented) that allows air to be easily released. It automatically and reliably eliminates air that may mix into the pump head, quickly expelling it during restart after long periods of inactivity or during low-speed operation. ■ Air block mechanism that prevents air from mixing into the pump head (DCLPW only) An air block mechanism that prevents air mixing. Even when up to 15cc of air is rapidly injected, no air will mix into the pump head. ■ Pump head designed to minimize air retention The flow path within the pump head is minimized to reduce dead space, decreasing the amount of air mixing and retention, thereby increasing the compression ratio for easier air expulsion. ■ Transparent acrylic head for easy visibility The transparent acrylic head allows for immediate visibility of the pump's operational status, as well as the state of air mixing and retention. ■ Dedicated injection nozzle to prevent clogging at the injection point The dedicated nozzle prevents backflow of raw water and crystallization or clogging due to reactions with raw water at the injection point. Please feel free to contact us as we will help you select and introduce the most suitable product for you.

On November 6th (Thursday) to 7th (Friday), 2025, we held the "Human Body Day 2025" at the NAC Image Technology Akasaka Multi-Purpose Space. We have uploaded videos of the highlights from each company and the presentations that took place on the day to our website. We encourage you to take a look. ---[Report on Human Body Day 2025 is here]------------------- https://info.nacinc.jp/jintaiday2025-report ------------------------------------------------------------------------- On the day of the event, participants were able to experience a wide range of products in a hands-on session format, including motion capture, force plates, eye tracking, and human body analysis software. We received numerous comments from attendees expressing high satisfaction, saying, "It was great to gain various information all at once," which makes us very happy. NAC Image Technology will continue to provide "valuable products to our customers." We hope you will join us for our next event as well.

The "Mechanical Stitch 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 causing any thermal impact to the base material. 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.
