【Case Study of Printing Equipment Manufacturing and Sales】 ●Product Model Numbers ・666053-3EB ・666053-344 ●Usage Environment and Purpose 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 necessary for the pump to be capable of discharging and recovering 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 can change, the pump needed to allow for easy adjustment of discharge and recovery amounts. We purchased it because it met these conditions. ●Benefits of Implementation and Post-Implementation Impressions 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 be easily switched between discharge-only, recovery-only, and both discharge and recovery.
