Valveless piston metering pumps from Fluid Metering Inc. (FMI) provide precision fluid control for environmental monitoring, sampling and treatment applications. The low-current DC motor is ideal for extended 12/24 volt battery operation in remote locations. The design of the company's CeramPump(R) uses one moving part, a rotating and reciprocating ceramic piston, to accomplish both pumping and valving functions without valves. The piston and mated liner are made of dimensionally stable, sapphire-hard ceramics that ensure long term, drift-free accuracy of 1% or better for millions of maintenance-free cycles.
