Precision Fluid Control for Food & Beverage Ingredient Additions

Fluid Metering, Inc.’s (FMI’s) Valveless Metering Pumps provide precision dispensing of additives for Food processing applications. Addition of vitamins, colors, flavors, fragrances, enzymes and preservatives are typical ingredients, which benefit from FMI’s valveless piston technology.

Often in concentrated form, FMI pump’s precision of 0.5% ensures product consistency, while eliminating waste of expensive ingredients.

FMI’s patented valveless CeramPump^® pumping principle utilizes one moving part, a sapphire-hard ceramic piston, to perform all fluid control functions, eliminating valves typically present in other low volume metering technologies. Elimination of valves, as well as having dimensionally stable ceramic internals, results in a pump that will provide millions of maintenance-free dispenses without the need for recalibration.

The IVSP Industrial Variable Speed Metering Pump (shown above) is ideal for viscous fluids. It has a rugged 1/4 HP variable speed drive motor and available with sanitary quick-disconnect fittings. Speed is controlled via a DIN mountable controller for both manual and electronic speed control.

The valveless function is accomplished by the synchronous rotation and reciprocation of the ceramic piston within a precisely mated ceramic liner. The reciprocation action of the piston, similar to a standard piston pump, accomplishes the pumping function. However, that’s where the similarity ends.

The piston also rotates, alternately aligning a flat at the end with the inlet and outlet ports of the pump. When the flat is aligned with the inlet port, fluid can be drawn into the pump. When the flat is aligned with the outlet port, fluid can exit the pump. Only one port is open at any time and at no point are both ports interconnected. This effectively functions as, and replaces, conventional check valves.

For over 55 years FMI pumps have been used Food & Pharmaceutical Processing; Medical, Analytical, & Laboratory Instrumentation; Industrial Process, Water & Wastewater Treatment, Environmental Monitoring, and much more.
