Fluid Metering is touting a new valveless waste transfer pump that is designed to remove waste fluid created by medical diagnostic instrumentation while analyzing patient fluid samples.
Waste fluid usually has a mixture of patient samples, like blood components and urine samples, that get combined with reagents, byproducts of reagent reactions and wash fluids. The fluids typically have a lot of different physical characteristics, including viscosity, suspended solids, human tissue and blood cells.
The valveless, brushless DC waste transfer pump from Fluid Metering uses Fluid Metering’s unique CeramPump valveless piston fluid control technology. It also includes a moving part, a rotating and reciprocating ceramic piston, that controls fluid within the pump and reduces the need to check valves.
The solids in waste fluid generally cause valves to stick, clog and fail which eventually leads to the pumps having to be removed from the systems for servicing.
Fluid Metering’s pump can easily be integrated into existing system designs that have a 24V DC input supply. With its 6-by-2-by-2-ft footprint, flow rates can be factory calibrated from 20 ml per minute to 400 ml per minute.
