The Duplex Pump provides a streamlined solution for metering, mixing, and dispensing two fluids from a single integrated system. Two independently adjustable CeramPump® heads driven by one motor deliver synchronized, repeatable flow, reducing system complexity while supporting precise dual-fluid control in a compact footprint.
Independent adjustment of each pump head enables ratio control from 1:1 to 1:100 for mixing, dilution, and dual-channel delivery. Chemically inert ceramic components and a valve-free fluid path minimize drift, supporting stable, long-term performance that often exceeds the lifetime of the instrument.
