The company’s miniature, stepper-driven valve-less OEM pumps are viable for use in low and micro-volume fluid control in medical diagnostic and clinical chemistry instrumentation. They rely on a patented CeramPump valve-less pumping principle with precision stepper control. The CeramPump involves one moving part, a sapphire-hard ceramic piston, to perform all fluid control functions, eliminating valves typically present in low volume metering technologies. The valve-less function is accomplished by the synchronous rotation and reciprocation of the ceramic piston within a precisely mated ceramic liner. The reciprocation action of the piston, similar to a standard piston pump, accomplishes the pumping function. However, the piston also rotates, alternately aligning a flat at the end with the inlet and outlet ports of the pump. When the flat is aligned with the inlet port, fluid is drawn into the pump. When the flat is aligned with the outlet port, fluid exits the pump. Only one port is open at any time and at no point are both ports interconnected. This effectively functions as, and replaces, conventional check valves. For more details and specs, go to http://fluidmetering.com/sth-feature.html
