Trochoidal type internal gear pump for chemical raw materials

Trochoidal type internal gear pump for chemical raw materials

For the transport of anaerobic liquids! Ideal for transporting liquids that must not come into contact with air, such as polyurethane raw materials!

The internal gear pump is a pump that operates on the principle of an internal gear mechanism, where an external gear and an internal gear mesh together and rotate while tracing a trochoidal curve. This pump, specialized for chemical raw materials, uses two seals made of special PTFE (Teflon) and fills the space between the seals with solvents or plasticizers. It can safely isolate the external air, preventing the curing of isocyanates due to contact with the outside air. It is ideal for the transfer of urethane raw materials (isocyanates, polyols). 【Features】 ● For the transport of anaerobic liquids 　→ By using special PTFE (Teflon) seals and sealing the liquid between the seals, it prevents contact between the liquid and external air. It is optimal for transporting liquids like isocyanates, which are strictly prohibited from contact with air. ● For use at high temperatures 　→ This model can withstand temperatures up to 120°C. If you require higher temperatures, please consult us. ◎ Download the catalog 　→ You can view the specifications of all 11 models. Additionally, we also offer internal gear pumps for fuel oil. You can find more details by downloading the same catalog.

[Case Study] Space-saving Neutralization Treatment of Medical Wastewater

[Case Study] Space-saving Neutralization Treatment of Medical Wastewater

Space-saving neutralization in the clinic! Introducing a case study of an automatic pH neutralization device.

We received a contact from a design company in the Kanto region and would like to introduce a case where we delivered an "automatic pH neutralization device" to Kanto Gastroenterology Clinic. The request was to "neutralize the wastewater from the cleaning machine," and the available installation space was approximately 500×500 mm with a height of about 1000 mm. Within this range, it was necessary to complete the chemical injection, stirring, and control panel. Due to the need for installation within the clinic, space-saving installation was a must, and there were strict requirements for operation on 100V single-phase power and minimal operational noise. We ordered a custom-sized control panel and achieved space-saving by mounting everything above the neutralization tank. [Case Overview] ■ Challenges - Need to neutralize wastewater from the cleaning machine - Must complete chemical injection, stirring, and control panel within the installation range - Space-saving installation is essential due to in-clinic installation - Operation on 100V single-phase power - Operational noise must be kept to a minimum *For more details, please refer to the PDF document or feel free to contact us.
