Example of diaphragm pump adoption: Pharmaceutical raw material manufacturer: Zinc oxide slurry

Example of diaphragm pump adoption: Pharmaceutical raw material manufacturer: Zinc oxide slurry

[Industry Case Studies Available] Introducing examples where equipment lifespan has increased even for slurry-type liquids.

We would like to introduce a case study of our air-driven diaphragm pump, the "One Nut Pump." ★Target Users: Pharmaceutical Raw Material Manufacturers (Zinc Oxide Slurry) The manufacturer had been using pumps from other companies, which required approximately 10 overhauls and parts replacements over three years, leading to serious issues with pumping zinc oxide slurry. Therefore, they switched to our "One Nut Pump." For the three months following the change, up until the preparation of this report, pumping has been possible without any issues. Additionally, the SUS316L body of the pump, made through machining, has resulted in a longer lifespan for the equipment when handling slurry-type liquids. 【Case Study Overview】 ■Pump Series: Slim Type ■Pipe Diameter: 2” ■Discharge Pipe: 5m Head *You can view the "Usage Collection," which summarizes all case studies, immediately through PDF download. We also welcome any inquiries you may have.

[Case Studies of Diaphragm Pump Adoption] Hydrochloric Acid / Caustic Soda / Liquid Fragrance

[Case Studies of Diaphragm Pump Adoption] Hydrochloric Acid / Caustic Soda / Liquid Fragrance

[Industry Case Studies Available] Preventing Damage and External Contamination! A Case Study That Significantly Reduced Maintenance Time

We would like to introduce a case study of our air-driven diaphragm pump, the "One Nut Pump." ★Application: Hydrochloric Acid / Caustic Soda / Liquid Fragrance, Burst Prevention System, Alarm A specialty chemical manufacturer has significantly reduced maintenance time by using the polypropylene "One Nut Pump" compared to the pump they previously used. Previously, maintenance took half a day, but with the "One Nut Pump," it takes only about 30 minutes, and replacing the diaphragm is very easy, taking just about 20 minutes. With the burst prevention system option, the diaphragm is doubled, so in the event that the primary diaphragm fails, the fluid is retained within the secondary diaphragm, preventing damage from hazardous products inside the pump and external contamination. 【Case Study Overview】 ■ Pump Series: 500 Series ■ Pump Model: F33PPTTPEBSP ■ Products: Hydrochloric Acid (36%), Caustic Soda (32%) ■ Product Temperature: 0–80℃ *You can view the complete "Case Study Collection" compiled from all examples via PDF download. We also welcome any inquiries you may have.

[Case Study of Diaphragm Pump] Latex/Emulsified Mixture

[Case Study of Diaphragm Pump] Latex/Emulsified Mixture

[Industry Case Studies Available] Significant benefits in terms of productivity! Examples of greatly improved production efficiency.

We would like to introduce a case study of our air-driven diaphragm pump, the "One Nut Pump." ★Target Application: Latex/Emulsified Mixtures The pump previously used by the relevant company required operators to travel back and forth a distance when turning the pump ON/OFF. The "One Nut Pump" is designed to close the discharge side, putting the pump in a deadhead state, and it restarts when the same valve is opened, eliminating the need to travel 80 meters back and forth, significantly improving production efficiency. The "One Nut" design allows for easy disassembly of the pump, minimizing the time required for the cleaning process and extending the lifespan of the diaphragm, providing substantial benefits in terms of productivity. 【Case Study Overview】 ■Pump Series: 500/700 Series ■Flow Rate: Approximately 670/min ■Viscosity: Approximately 200cps *You can view the complete collection of all case studies in the "Usage Collection," available for immediate PDF download. We also welcome any inquiries you may have.
