The diaphragm is the driving force behind every Yamada pump. Selecting the wrong material can lead to tearing, deformation, reduced efficiency, and costly, unnecessary downtime. With the right diaphragm, however, your pump operates longer, safer and with minimal maintenance.
As an official Yamada distributor, Flowtec helps you choose the optimal diaphragm for your specific pump model and application. Yamada offers a broad range of materials, each engineered to perform under different chemical, temperature, and process conditions.
