Diaphragm Pumps Key benefits Positive displacement pumping that handles a wide range of liquids without contaminating the fluid stream. Selfpriming and tolerant of intermittent operation; continues to pump reliably even when run dry for short periods. Lowshear operation protects shearsensitive fluids and suspended solids from damage. Simple serviceability: replaceable diaphragms and valves minimize downtime and maintenance cost. How this pump solves problems Eliminates sealing leaks because the pumped fluid is isolated by the diaphragm, reducing contamination and maintenance from shaft seals. Handles fluids with solids, viscosity, or chemical aggressiveness where other pumps clog or fail. Adapts to varying flow and pressure demands through stroke or speed control, reducing the need for multiple pump types. What makes it stand out Flexible diaphragm design provides a reliable barrier between drive and process liquid. Robust construction suited to repeated start/stop cycles and intermittent duty. Versatile mounting and connection options support integration into existing systems. Important attributes Function: positivedisplacement diaphragm mechanism that alternately flexes a membrane to move fluid; check valves control inlet and outlet flow. Compatibility: suitable for water, chemical solutions, slurries and shearsensitive liquids. Select diaphragms and wetted materials based on chemical compatibility for specific applications. Size: available in compact bench units to larger inline or skidmounted configurations to match space and capacity requirements. Material: commonly supplied with plastic or metal wetted parts and elastomeric diaphragms; material selection determines chemical resistance and service life. Performance: provides steady flow at variable pressures; effective for low to moderate flow rates where precise metering or gentle handling is required. Installation and maintenance Simple piping connections and flexible mounting options ease installation. Routine maintenance typically involves diaphragm and valve inspection/replacement; no shaft seal servicing is required. Periodic checks for diaphragm wear and valve seating extend service intervals. Typical use scenarios Water and wastewater treatment: chemical dosing, polymer transfer, flocculant feeding and sampling where accurate, contamination transfer is required. Chemical processing and plating: transfer of corrosive or abrasive solutions using appropriate wetted materials. Manufacturing and laboratory: dosing of adhesives, inks, paints or shearsensitive formulations in production lines or bench setups. Select materials and diaphragm options based on your fluid's chemical compatibility and solids content to ensure reliable, longterm operation.
