Diaphragm Pumps What this pump does Positivedisplacement pump that moves fluid by the reciprocating action of a flexible diaphragm. Designed to provide leakminimized, controlled transfer of liquids across a wide range of viscosities and chemistries. Suited to intermittent or continuous duty and to applications where contamination, leakage, or shearsensitive handling are concerns. Key benefits — why you need it Leakresistant and safe: The diaphragm barrier reduces the risk of external leaks, making the pump suitable for hazardous or corrosive fluids. Broad fluid compatibility: Works with low to viscosity liquids, slurries, and fluids containing solids when configured with appropriate wetted components. Gentle handling: Low shear action protects shearsensitive materials such as emulsions and biological fluids. Reliable priming and operation: Selfpriming capability improves installation flexibility and reduces downtime. Low maintenance and long service life: Simple mechanical design with replaceable diaphragms and valves keeps service time and costs low. Precise metering and consistent flow: Positivedisplacement action supports repeatable dosing and stable delivery under varying back pressures. Important attributes Function: Positivedisplacement diaphragm action delivers a controlled, pulsecharacteristic flow suitable for transfer, dosing, and recirculation tasks. Compatibility: Available in configurations to match many chemical families, viscous media, and particulateladen fluids; selection of wettedpart options lets you tailor chemical resistance and abrasion performance. Size and installation: Offered in compact to industrial package sizes, suitable for benchmounted, panel, or line installations; simple connections and adaptable mounting ease integration. Materials and serviceability: Wetted components and diaphragms are designed to be serviceable and replaceable to extend pump life and simplify maintenance cycles. Performance: Delivers repeatable flow and pressure for process control; designed to tolerate brief dryrun conditions when appropriately specified. Practical use scenarios Chemical transfer and metering: Safely move and dose corrosive process chemicals from drums, totes, or tanks into process lines with minimal leakage risk and accurate repeatability. Wastewater and solids handling: Transfer slurries, sludge, or particulatebearing fluids where a sealed pumping method reduces leaks and clogrelated downtime. Process and laboratory dosing: Provide controlled, lowshear delivery of reagents, additives, or formulations where precise volumes and gentle handling matter. How to choose/configure Match wettedcomponent compatibility to the fluid's chemistry and abrasion level. Select the pump size and displacement based on required flow and head, and consider options for pulsation dampening or backpressure control if needed. Plan for regular diaphragm and valve inspection/replacement as part of preventive maintenance.
