Miniature Valveless Pumps

Fluid Metering, Inc

Fluid Metering, Inc, manufactures miniature stepper-driven valveless OEM pumps that are ideal for low and micro-volume fluid control in medical diagnostic and clinical chemistry instrumentation. The OEM pumps integrate FMI's CeramPump valveless pumping principle with precision stepper control. The CeramPump utilizes one moving part, a sapphire-hard ceramic piston, to perform all fluid control functions. The valveless function is accomplished by the synchronous rotation and reciprocation of the ceramic piston within a precisely mated ceramic liner. Utilizing sapphire-hard dimensionally stable components, as well as eliminating check valves, results in a pump that will maintain 0.5% precision for millions of cycles without maintenance or recalibration.
