DBY electric diaphragm pump

Electric-driven double-diaphragm (DBY) pump engineered for industrial fluid transfer where chemical resistance, particulates, viscosity or volatility are concerns. The pump is driven by an electric motor through a reducer and is suitable for handling corrosive liquids, liquids containing solids, high-viscosity media, volatile or flammable fluids, and other demanding industrial liquids.

Ordering and configuration

This model is available in multiple material and motor configurations to match fluid compatibility, temperature and site-safety requirements. Specify required flow/head, fluid characteristics (viscosity, solids content, temperature, chemical composition) and preferred materials or motor type when requesting a quote or technical datasheet.

Note: Verify material compatibility for aggressive chemicals, high temperatures or food-grade applications prior to selection.
