This is a gas-lock-free type pump specifically designed for sodium hypochlorite injection. 【Main Features】 ■ Automatic air venting mechanism that reliably eliminates sucked-in air Adopts a special valve seat mechanism (patented) that facilitates air venting. Even if air mixes into the pump head or is generated within the pump head, it is automatically and reliably eliminated. It also quickly removes air during restart after long periods of inactivity or during low-speed operation. ■ Air block mechanism that prevents air from mixing into the pump head (only for DCLPW) The DCLPW is equipped with an air block mechanism that prevents air mixing. Even if up to 15cc of air is injected at once, no air will mix into the pump head. ■ Pump head structure that minimizes air retention The flow path within the pump head is minimized to reduce dead space, decreasing the amount of air mixing and retention while increasing the compression ratio, making it easier to discharge air. ■ Transparent acrylic head for easy visibility of the pump head interior The transparent acrylic head allows for immediate visibility of the pump's operating condition, as well as the state of air mixing and retention. ■ Sodium hypochlorite-specific injection nozzle to prevent clogging at the injection point The injection nozzle developed specifically for sodium hypochlorite prevents backflow of raw water and crystallization or clogging due to reactions with raw water at the injection point.

However, there were challenges such as "damage that can occur unknowingly due to corrosion from sulfuric acid" and "the need for pump overhauls every three years, incurring costs each time." Please download the PDF document to see the solutions to the challenges and requests. 【Customer's Challenges and Requests】 ■ An accumulator was installed to eliminate pulsation, but it can be damaged unknowingly due to corrosion from sulfuric acid. ■ Due to long-distance piping, a high-pressure pump is used considering pressure loss, and continuing operation without the accumulator functioning poses a risk of pipe damage, which is very dangerous. ■ Pump overhauls are required every three years, incurring costs each time. *For more details, please refer to the PDF document or feel free to contact us.

The electronic component manufacturer was using a gear-type pump to supply a slurry-like high-viscosity liquid (3000 mPa·s) to the coating machine. However, there were issues such as "the slurry particles getting clogged in the pump, causing it to stop" and "severe wear on the pump, leading to a decrease in flow rate in a short time." For solutions to these issues and requests, please download and view the PDF document. 【Customer's Issues and Requests】 ■ The slurry particles got clogged in the pump, causing it to stop. ■ There was severe wear on the pump, leading to a decrease in flow rate in a short time. *For more details, please refer to the PDF document or feel free to contact us.

The request from the petrochemical manufacturer was to transfer organic solvents (diglyme) containing micro-particles of a few microns. Furthermore, they requested that "the flow rate be 50L/min and the discharge pressure be 0.5MPa" and that "they want to monitor and record the actual flow rate." For solutions to the challenges and requests, please download and view the PDF materials. 【Customer's Challenges and Requests】 ■ Flow rate of 50L/min and discharge pressure of 0.5MPa are required ■ They want to monitor and record the actual flow rate *For more details, please refer to the PDF materials or feel free to contact us.
