FMI: Low-Current DC Pumps For Extended Use In Remote Locations
September 29, 2004
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.
