Valveless Piston Pump

Advantages of a valveless piston pump:

- There are no valves to service, leak, hang up, or clog.

- Features only one moving part.

- Equipped with ceramic internals.

- Ensures drift-free operation.

- Offers precision dispensing with a variation coefficient of -0.5%.

- Flow rates range from microliters to 2.3 liters/min.

- Provides positive displacement up to 6.9 barg.

- Capable of self-priming up to 4.5 meters.

- Features instant reversibility.

- The fluid path is inert, made of ceramic and fluorocarbon.

- Performance is viscosity independent.

- Comes with a wide selection of drives.

Fluid Metering Inc. has been a leading manufacturer of metering pumps and dispensers for over 60 years in the USA, having introduced the first valveless rotating and reciprocating piston metering pump. Over time, FMI's metering pumps have been refined and remain a benchmark for accuracy, precision, and durability in the industry.
