DBY Electric Diaphragm Pump

I. Product Overview

The DBY series electric diaphragm pump represents a new type of pump. Thanks to recent breakthroughs in diaphragm material technology, this pump type is increasingly adopted in industrialized nations across the globe—replacing other pump types—for applications in industries such as petrochemicals, ceramics, and metallurgy. The product design is based on prototypes from the US company ABEL; the pump is suitable for low-pressure applications (specifically, an outlet pressure of ≤3 kgf/cm²).
