Ultra-Precise Fluid Control. . . from Microliters to Liters
FMI is a metering pumps and dispensers manufacturer, who pioneered the first valveless rotating and reciprocating piston metering pump concept over 56 years ago. Enhanced and improved over the years FMI metering pumps continue to provide innovative fluid control solutions. Our dispensers and metering pumps are the industry standard for high degree of accuracy, precision and reliability.
Utilized in a broad range of Medical, Laboratory, Analytical, Industrial Process, Environmental and OEM applications requiring precision fluid control, FMI pumps have provided users with the ultimate performance.
Our Unique Valveless Pump Design Features:
- Patented “No-Valve” Pump Design
Eliminates problems and errors caused by valves which clog, leak, hang up,
and require service.
One Moving Part!
FMI’s CeramPump® design utilizes a single, dimensionally stable, chemically inert CERAMIC piston ensuring long term, drift free fluid control. The valveless pumping function is accomplished by the synchronous rotation and reciprocation and reciprocation of the ceramic piston in the precisely mated ceramic cylinder liner. One complete piston revolution is required for each suction/discharge cycle.
- Accuracy, Precision, & Reliability
Long term drift free performance measured in millions of “trouble-free” cycles. Fluid Metering Pumps accuracy is held from microliters to the full flow range. Output does not
change more than ± 1% of set value. An important cost saving factor considering the waste
generated by inaccurate pumps
- Proven Performance!
Over 56 years of experience and more than 1 million metering pumps and
dispensers in service.
Fluid Metering, Inc. (FMI) manufactures unique, patented, valveless piston metering pumps and dispensers.
FMI Pumps utilize only one moving part, a rotating and reciprocating ceramic piston to accomplish all fluid control functions within the pumps, thereby eliminating valves and their associated maintenance.
Flow rates range from 2.5 μl/dispense to flows of 4,600 ml/min with pressures to 100 psig.
FMI pumps will dispense and meter fluids for millions of cycles with a drift free accuracy precision of 1% or better.
These pumps are ideal for Medical Applications including precise dispensing, aspirating, rinsing, & mixing systems and for syringe pump replacement in diagnostic, clinical chemistry, dialysis and medical equipment manufacturing. Also for dispensing adhesives and lubricants used in assembly of disposable medical components.
Ideal in other industries with typical applications including fluid metering, dispensing and sampling for chemical process, laboratory, pilot plant, food processing, water treatment, and environmental analyzers.
