【Case Study on the Introduction of Diaphragm Pumps in Printing Equipment Manufacturing and Sales】 ● Usage Environment and Application Our company handles high-viscosity chemical solutions and uses diaphragm pumps as circulation pumps. ● Reason for Purchasing the Product To select an appropriate circulation pump, it was essential that the pump could discharge and recover the chemical solution. Additionally, the pump itself needed to have chemical resistance suitable for the type of chemical solution being used. Finally, since the viscosity of the chemical solution may change, it was important that the pump could easily adjust the discharge/recovery volume. We purchased it because it met these criteria. ● Advantages of Introduction and Post-Implementation Feedback The advantages of adopting the diaphragm pump include its reliable operation. The pump is compact and can be easily mounted on the equipment. By changing the assembly method of the pump, it can easily switch between discharge-only, recovery-only, and both discharge and recovery. ● Product Model Numbers - 666053-3EB - 666053-344
