Reliability, repeatability and flexibility are among the essential requirements when choosing a pump for dispensing and filling duties in medical, laboratory, pharmaceutical, electronics, food and other similar applications.  FMI has developed a wide range of ceramic piston pumps which include these features and benefits.

FMI pumps are designed for simple and reliable operation and require minimal maintenance, thanks to features such as no valves to clog, leak or service and just one moving part - the piston. They offer drift-free operation of better than 1% from set point, precision dispensing of -0.5% CV, flows from microlitres up to 2.3 l/min with positive displacement pumping and dispensing up to 6.9 barg.  The pumps are also self-priming and offer instant reversibility so they will pump in either direction.

Typical applications for FMI piston pump include accurate dispensing of sensitive fluids in medical, biotech and pharmaceutical applications, transferring corrosive fluids in industrial and electronics manufacturing, metering and mixing paints, metering petroleum additives, photo chemicals, inks, coating sweets and the addition of flavours.
